Impact of different types of fertilizers to reduce the population density of the sap sucking pests to bean plants
The experiment was laid out in a randomized complete block design with three replicates. The aim of the work is to investigate the effect of different fertilizers on the rates of beans infestation by different piercing sucking pests Tetranychus urticae, T. cucurbitacearum, Bemisia tabaci and Thrips tabaci and on the resulting crop yield. The fertilizer treatments are Ammonium sulfate, Calcium super phosphate, Potassium sulfate, a mixture of NPK and Micro-elements (Zn, Mn, Fe, Cu, Bo & Mo). Results showed that means of green pods yielded by NPK fertilizer was significantly higher than other fertilizers in the two seasons

Biological Aspects of the Spider Theridion incanescens (Araneae: Theridiidae) Feeding on Tetranychus urticae and Ceratitis capitata With Notes on its Mating Behaviour
The life history of Theridion incanescens Simon, 1890 is studied for the first time in Egypt. T. incanescens was first recorded from Egypt in 2012. It was collected from Aloe vera cultivated in Giza, mango, citrus and grape trees at El-Sharqia & Ismalia. The individuals were reared under laboratory conditions and were fed every two days on motile stages of Tetranychus urticae (Koch, 1836) until reaching to subadults, after that they were fed on Ceratitis capitata (Wiedemann). The males and females reached maturity in the fifth instar after 41–47 & 34–52 days respectively.Adult longevity, life span, fecundity of female and food consumption were studied too. The mating behaviour of T. incanescens was described. It began with courtship followed by four copulatory sequences. Total duration of themating behaviour was 3:05 hour.

Insecticidal potential of the bioagent radiant sc 12% against stored rice weevil, Sitophilus oryzae L. (Curculionidae: coleoptera)
The bioagent, Radiant SC12% (Spinetoram) is a commercial reduced-risk pesticide that is naturally derived. Efficacy of five concentrations (1.8, 0.93, 0.46, 0.23 and 0.11ppm) of spinosad against adults of the rice weevil, Sitophilus oryzae was studied under laboratory conditions. Data obtained demonstrated that the highest concentration of the bio-agent Radiant SC 12% (1.87 and 0.93 ppm) achieved the highest mortality percent of adults (55 and 31 %, respectively) after 4 days of treatment and 100 mortality percent for both two concentrations after 6 and 8 days of treatment. Antioxidant defense components protect insects by scavenging reactive oxygen species, leading to oxidative stress. The present study also investigated the effects of Radiant SC 12%, on the oxidative stress indicator, and antioxidant enzymes [superoxide dismutase (SOD) and catalase (CAT)] activities in Sitophilus oryzae tissues. The use of the bio- agent lead to statistically significant increases in SOD and CAT activities after 48h of application as compared to untreated Sitophilus oryzae. These results indicated that Radiant causes a significant increase in oxidative stress, that increasing oxidative stress induces antioxidant defense mechanisms, which lead to mortality action.

Influence of larval density on some biological and demographic aspects of Chrysomya megacephala (Diptera: Calliphoridae).
The objective of this work was to study the influence of larval density on some aspects of the population ecology & survival of Chrysomya megacephala, analyzing demographic aspects of adults kept under experimental conditions. A positive effect of density on survival and pre-ovipostion period was observed, while no simultaneous influence of density in sex ratio. The results showed that the demographic parameter for life expectancy at intrinsic growth rate (e0), total fecundity (TF), net fecundity (NF) and men reproductive age (T) increased with increasing the density of population larvae. Other population parameters such as the intrinsic growth rate (r), the finite growth rate (λ) and the time to double population (DT) were also calculated.

New Formula of Pollen Supplemental Diets to Study Honey Bee (Apis mellifera carnica) Attractiveness
The present work aimed to examine the attractiveness of ten new pollen supplemental diets to honey bees (Apis mellifera) through evaluating the consumption rate, besides their efficiency in supporting the colony through measuring colony growth (sealed workers brood area). Twelve materials were used and mixed with honey bee in different proportions forming diets taking numbers from 1 to 10. These materials were flours of: gram seeds, beans seeds, pea seeds, fenugreek seeds, coriander seeds, cumin seeds, anise seeds, white kidney beans seeds, caraway seeds, rice seeds, fennel seeds and oats. Diets were consumed at rates that were comparable to the control (sugar candy). Generally differences among consumption rates of supplemental pollen diets were highly significant. The highest consumed amounts were recorded in colonies fed on diet (1); 47.42gm/ colony in average, mix. (2); 43.35 gm/ colony in each week. While the lowest consumption rate (27.3 gm/ colony) in each week was recorded for diet no. 10 in average. There was a significant relationship between the amount of diet consumed and the increase in workers sealed brood area. Where colonies fed with mixture diets from gram seeds (Diet 2), dried pea with rice, fennel and fenugreek (Diet 3), dried beans seeds with fennel seeds (Diet 4) and oats, rice, anise seeds (Diet 1), showed 53.71%, 38.44%, 35.98% and 5.85% more brood area than control ones.

Persistence of Entomopathogenic Nematodes and Fungi in Soil around Olive Trunks and Their Virulence to Zeuzera pyrina L.
The present work has been conducted through a project for biological control of olive pests in Aljouf region, Saudi Arabia Kingdom. (Steinernema spp., SAK1 isolate), (Ord. Rhabditida: Fam. Steinernematidae) and (Heterorhabditis spp., SAK2 and SAK3 isolates), (Ord. Rhabditida: Fam. Heterorhabditidae) were applied in soil around trunks of olive trees. Successive soil samples were tested for persistence and their virulence to larvae and pupae of Zeuzera pyrina L; where it is attacking olive trees and strongly considered one of the most dangerous pests. Heterorhabditis spp., SAK2 and SAK3 isolates achieved 100 % mortality to larvae and pupae of Z. pyrina at the second day, where mortality gradually decreased to 22.2 and 11.1 % after 16 days for both larvae and pupae, respectively. Steinernema spp., SAK1 isolate was less virulent, it caused 88.9 and 50.5 % mortality after two days and no mortality achieved after 16 days for both larvae and pupae of Z. pyrina, respectively. After two and four days, mortality due to the fungus is 66.7 and 44.4 %, respectively, where no mortality achieved after 8 and 16 days for both larvae and pupae of Z. pyrina, respectively. On the other hand, applying nematodes either via spraying or injection in olive branches infested with Zeuzera pyrina larvae and /or pupae caused 100% control to the insect stages inside the branches within seven days.

Comparison between the infestation rate of certain pests on cucumber and kidney bean and its relation with abiotic factors and anatomical characters.
Two host planst, Cucumber, Cucumis sativus L. and kidney bean Phaseolus vulgaris L.were sown at Horticultural Research Station at Kaha region, Qalubiya Governorate, Egypt to determine the host preference to certain pests including, thrips Thrips tabaci (Lind.), aphids, whitefly, Bemisia. tabaci (Genn.) and the two spotted spider mite, Tetranychus urticae (Koch) and its relationship with climatic factors and anatomical characters during two successive seasons 2011 and 2012.
The results indicated that the infestation rate of B. tabaci and T. tabaci increased on cucumber leaves more than kidney bean. On the contrary, kidney bean was suitable host to development of aphid and T. urticae. The incidences of the four studied pests were significant and positive correlated with maximum temperature and maximum relative humidity. While, the population density of these pests positively correlated and non-significant with minimum temperature. On the contrary, the minimum relative humidity had negative and non-significant effect on the two host plants.
In the two host plants, anatomical characters of play an important role in the infestation rates of the previously mentioned pests. Kidney bean had the thickest layers of upper& lower epidermis and spongy tissues and the thinnest layer of palisade tissue. On the other hand, cucumber leaves had the thickest layer of palisade tissue. The population density of all pests had positive relationship and significant with palisade and spongy layers. While, this relation was significantly negative with upper and lower epidermis. i.e., infestation rates of all studied pests increased by increasing the thickest layers of palisade and spongy tissues and decreased by increasing the thickest of upper and lower epidermis. The amount of variability that could be attributed to the combined effect of the tested weather factors and anatomical characters on the four studied pests was more than 60%.

Effect of certain climatic factors and plant age on the population density of leafminers , Liriomyza spp. infesting Fenugreek plants, Trigonella foenum- graecum L. in different planting dates.
An experiment was carried out to study the effect of planting date, climatic factors and plant age on the population density of Leafminers, Liriomyza spp. infesting fenugreek plants in Plant Protection Research Station at Kaha region during two successive seasons 2010-2011 and 2011-2012.
The obtained results revealed that the population density of Liriomyza spp larvae on fenugreek plants differed significantly according to the planting dates (Oct.,31st, Nov., 15thand Nov.,30th) during the two studied seasons. Planting of fenugreek seeds in the early planting date (Oct., 31st) lead to plants suffered from the highest infestation by Liriomyza spp. larvae. On the contrary, sowing the fenugreek at the second date (Nov., 15th) can be reduced the infestation rate of this insect pest.
The population density of leafminers, Liriomyza spp increases by increasing the plant age. The lightest population was recorded during the vegetative stage. While the fenugreek plants infested by the heaviest population during flowering and fruiting stages.
Statistical analysis of correlation coefficient values showed that the effect of climatic factors on the population density of Liriomyza spp. was differed positive or negative correlation according to plant stages (vegetative, flowering and fruiting stages) during two studied seasons. The population density of Liriomyza spp. correlated positively with plant age except for the early planting date (Oct., 31st) in the second season, as the calculated (r) values were 0.15, 0.68 and 0.48 for the three planting dates in the first season and -0.05,0.43 and 0.62 in the second season, respectively.
The climatic factors were more effective on leafminers population when comparing with plant age, as the explained variance (E.V. %) were 55.73, 70.83 and 42.93% for the three planting dates in the first season and 69.72, 78.59 and 39.40% in the second season, respectively.
The combined effect of the tested weather factors (maximum & minimum temperature maximum & minimum RH% and average wind speed) and plant age together on Liriomyza spp. population in the tested planting dates on different stages of fenugreek plants were 59.90, 73.15 and 66.82% at the three planting dates during first season and 72.74, 79.51 and55.82% during second season, respectively.

Biological studies on Bracon brevicornis (Hymenoptera: Braconidae) reared on different host larvae
The present work was carried out to study the biological aspect of B. brevicornis when reared on different hosts (Ephestia kuehniella, Galleria mellonella, Corcera cephalonica, Sesamia cretica, Spodoptera littoralis and Pectinophora gossypiella). Our Results assured that the type of host had great impact on the durations of the immature stages and longevity of the parasitoid. The highest & lowest incubation periods were when reared the parasitoids on Pectinophora gossypiella (45.75±1.4hours) and E. kuehniella (39.87±0.95 hours) respectively, the difference was insignificant at the other hosts. Duration of larval stages was significant shorter when parasitoid reared on S. cretica (1.86±0.079 days) than the rest hosts. The longer pupation period was recorded when parasitoid reared on Pectinophora gossypiella (7.6±0.13 days), but was insignificant on the other hosts. The highest duration period of immature stage was when reared B.brevicornis on P. gossypiella (12.75±0.74 days) but insignificant difference when reared on G.mellonella [ 9.16±0.22 days ] and S. cretica [ 9.91±0.14 days ]. The mean duration of male longevity of parasitoids was longer when reared on E. kuehniella (15.73±0.73 days) and shorter when reared on C.cephalonica (11.75±0.51 days). The mean duration of female parasitoids was highest when reared parasitoids on S. cretica (19.6±0.51 days). The total number of eggs laid per female of B.brevicornis during its life span was highest on Galleria mellonella (268.88±19.65 eggs), and lowest on C.cephalonica (78.1±10.63 eggs). A percentage of eggs hatchability was significantly lowest when reared on S. littoralis (0.09±0.02642 %) than when reared on the other hosts, while percentage of emergence was insignificantly different when reared on Sesamia cretica (87.36±3.92 %) and Pectinophora gossypiella (87.02±3.85 %).

Effect of planting date on seasonal abundance of the Aphis craccivora koch and the associated predators in the new Valley-Egypt
The population density of A. craccivora on broad bean plants of the recommended sowing date fluctuated in scarcely numbers to attain the peak (17.50 and 3.00 individuals/plant) during the third week of November of 2012/2013 and 2013/2014 seasons, respectively. On the other hand, the highest numbers (0.27 and 0.06 individuals/plant) of the coccinellid beetles included the larvae and adults of C. undecimpunctata and C. septempunctata were recorded during the second week of December and the third week of November of the two successive seasons, respectively. There was an insignificant positive and / or negative simple correlation (r) between the number of the pest and the population density of the coccinellid beetles.
The plants cultivated in the early planting date (first of October) harbored the highest number of the pest with an average of (22.72 individuals/plant). Meanwhile, the plants of the late planting date (end of October) harbored the lowest number of the pest with an average of (2.55 individuals/plant).
Broad bean plants of the early and recommended sowing date which harbored the high levels of infestation with A. craccivora recorded the highyields (gm)/plant. Meanwhile the plants of the late planting date which harbored the minimum number of the pest recorded the lowest yield (gm)/plant during 2012/2013 and 2013/2014 seasons.

Inhibited reproductive capacity of Egyptian cotton leaf worm Spodoptera littoralis (Boisd.) (Lepidoptera: Noctuidae) by the chitin synthesis inhibitor Novaluron.
For evaluating the effects of Novaluron on various parameters of the reproductive capacity of Spodoptera littoralis, a concentration range of 1.00-0.0001ppm was applied on the newly moulted penultimate (5th) instar larvae and a concentration range of 0.10-0.0001ppm was applied on the newly moulted last instar larvae. A predominant inhibitory effect of Novaluron was exhibited on the oviposition efficiency since the oviposition rate was seriously regressed in no certain trend, regardless the time of larval treatment and concentration level. Treatment of penultimate or last instar larvae with Novaluron resulted in drastically reduced fecundity in a dose-dependent course. A reducing action of Novaluron was exerted also on fertility after treatment of larvae with different concentration levels, regardless the time of treatment. After treatment of penultimate or last instar larvae with Novaluron, the embryonic development had been generally subjected to a retarding effect since the incubation period was pronouncedly prolonged, regardless the concentration level.

Field evaluation and biochemical studies of novel insecticide on the cotton leafworm, Spodoptera littoralis (Boisd).
Field evaluation for the efficacy of indoxacarb, spinetoram and methoxyfenozide against larval instars of S. littoralis, infested clover plants Trifoliuma lexandrium was studied at two different Governorates (Al- Qalyubia and El- Fayoum) during cultivation season 2012 - 2013.All three insecticides, of indoxacarb, spinetoram and methoxyfenozide had no great difference among themselves in reducing the larval population of S. littoralis with difference in the time needed to induce this reduction according to the mode of action of these insecticides.The initial reductionwas recorded after 1 day from spraying for indoxacarb and spinetoram while after 3 days from spraying for methoxyfenozide. Indoxacarb was the most effective insecticide followed by methoxyfenozide and spinetoram.Under semi-field conditions, results showed that, at Al- Qalyubia Governorate, persistence of indoxacarb is higher than other tested insecticides while, the half life of all tested compounds is short at El-Fayoum Governorate.Tolerance to the toxicity of the three tested insecticides increased as the larvae grew older from 2nd to 4thinstar.Biochemical clarification was carried out in an attempt to disclose the effect of sub-lethal concentration (LC50) of the three tested insecticides; on haemolymph contents of 6th instar larvae of S. littoralis which was treated as 4thlarval instar with LC50 of the tested insecticides and their effects on main components of insect metabolites and changes in protein patterns.

Detection of Enteric Pathogenic Bacteria Transmitted by Housefly (Musca domestica) in Riyadh
The house-fly, Muscadomestica L., not only is a nuisance pest, but also acts as an importantmechanical vector for lots of pathogenic microorganism agents, including:bacteria protozoa, worms, fungi and viruses amongst humans and animals. The aimof this study was to use Microbial methods for identification of bacteria thatare pick up by house-fly over the human. In this study totally 200 houseflieswere collected to isolate their bacteria from the centre, east, and west ofRiyadh. The common isolated bacteria were Escherichia coli with 85 cases(42.5%). Were Enteric pathogenic bacteria Helicobacterpylori was 63cases (31.5%), and other isolated bacteria wasStaphylococci aureus21 cases (10.5%), Pseudomonas spp. was 20 cases(10 %) and Proteus spp. Was 11 cases (5.5%). The results of the currentstudy confirm that flies are much more than a nuisance and that they posepotentially serious health risks. Consequently, the population of houseflieshas to be controlled

Isolation of Fungi from House fly (Musca domestica) at Slaughter House and Public Places in Riyadh
House flies have long been regarded as potential carriers of microorganisms especially fungi. Since pathogenic microorganisms are widespread in the environment, there is abundant opportunity for flies to become contaminated and in turn to contaminate the human environment and residential regions. The aim of this study was to isolate and identify fungi which transmitted by flies and present in environment at the Slaughter House and Public Places. In this study, a total of 250 Musca domestica (125 flies from the Slaughter House environments and 125 flies from the public places) were collected in Riyadh. Flies were treated and Sabouraud’s dextrose agar (SDA) was used for isolation of fungi. The main fungus isolates were Aspergillus spp. (66%). Penecillium spp. (14%), Fusarium spp. (11.3%), Alternaria spp. (6%) and among the filamentous fungi, (8.6%) of the isolates as Microsporum gypseum of dermatophytes was identified. The present study supports belief that the house fly is a carrier for fungal spores. Therefore they have to be controlled and density of their population should be reduced undertaken different vector control approaches.

Delimiting survey and seasonal activity of peach fruit fly, Bactrocera zonata and Mediterranean fruit fly, Ceratitis capitata (Diptera: tephritidae) at El-Beheira Governorate, Egypt
Peach fruit fly (PFF), Bactrocera zonata (Saunders) and Mediterranean fruit fly (MFF) are the most destructive insect pests of fruit and vegetables in Egypt. The current study was carried out over two successive years; 2012 and 2013 in thirteen districts of El-Beheira governorate and aimed to conduct a delimit survey and monitor the seasonal activity of PFF and MFF populations. The results showed that the PFF was recorded in almost all of the examined districts except for Edko district. Moreover, the PFF was not found in El-Mahmodiya district throughout the second study period, while the MFF was spread throughout all tested districts at both years. Inter–site comparison revealed significant differences in the abundance of PFF and MFF across the tested districts during 2012 and 2013 seasons. A significant positive correlation was reported between the population activity of PFF and MFF through 2012 (r=0.34), while a non-significant positive correlation (r=0.24) was obtained in 2013. Population growth rate (r0) of PFF was higher than that of the MFF through the first interval of population increase through both 2012 and 2013 seasons; 1.02 and 0.17 for PFF, and 0.83 and 0.13 for MFF, respectively. The r0 values of the MFF was higher than the PFF through the second interval of increase through both tested seasons; 1.04 and 1.10 for MFF, and 0.16 and 0.21 for PFF. It could be concluded that these two insects exchange their role as a key-pest of fruit hosts along the tested seasons.

Effect of different larval instars of Phyllocnistis citrella Stainton on some biological aspects of Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae) under laboratory conditions
Predatory potential of Chrysoperla carnea (Stephens) was studied on different larval instars of Phyllocnistis citrella (i.e. second, third and mixture of all larval instars) under laboratory conditions (26± 2ºC, 65±5% R.H, 16:8 L: D photo period).
Results revealed that feeding and rearing on different larval instars of P. citrella affected predator biology with different degrees. It had no significant effect on incubation period of C. carnea eggs females, pupation period, adult longevity and pre-and post - oviposition periods. On the other hand, it had significant effect on C. carnea larval period and its survival, female fecundity and eggs fertility. In general, third instar larvae of P. citrella was the most preferred prey for C. carnea. The results illustrate the potential importance of prey resources (life stage) on C. carnea population growth and indicate that C. carnea has considerable potential for the biological control of P. citrella.
