A mosquito larval survey was carried out in the southwestern region of Saudi Arabia. Twelve mosquito species were identified: 4 Anopheline species; Anopheles arabinesis Theobald, Anopheles tenebrosus Donitz, Anopheles multicolor Combouliu, and Anopheles sergenti Theobald and 6 Culicine species; Culex pipiens Linnaeus; Culex tritaeniorhynchus; Culex lutzia; Culex sinaiticus; Culex quinquefascitus Say; Culex theileri Theobad as well as one Aedine species, Aedes caspius, and Culiseta subochrea. Culex pipiens is the most common culicine species in the southwestern region.
The insecticidal activity of tested compounds (acetonic and ethanolic extracts of agricultural waste product, rice bran and plant,extract of Milkweed) was bioassay against the 3rd instars of the Culex pipiens larvae in the laboratory. Therefore, the toxicity of the tested plant extracts based on LC50 values could be arranged in an ascending order as follows: ethanolic extract of milkweed leaves < acetonic extract of milkweed leaves < acetonic extract of milkweed flower < acetonic extract of rice bran < ethanolic extract of rice bran < ethanolic extract of milkweed flower.
The SR of ethanolic extract of Rice bran with Triton x100 (1.64) was higher than other one.

The cowpea weevil, Callosobruchus maculatus (Coleoptera: Chrysomelidae), is the most serious insect pest attacking stored pulses in tropical and subtropical regions. The effects of maternal age on offspring fitness of the cowpea weevil have been previously studied, but the combined effects of maternal age and temperature are reported here for the first time. Adult longevity was negatively correlated with temperature, and female longevity was longer than males. The number of eggs deposited daily was negatively correlated with maternal age for the tested temperatures. Females required 24 hours longer at 20oC and 25oC and 12 hours longer at 30oC than males to develop from egg to the adult stage. The mean intrinsic rates of increase were 0.06, 0.10, and 0.15 at 20, 25, and 30oC, respectively. There was a significant positive correlation between maternal age and development time at 25oC. Percent survival was negatively correlated with the maternal age at 20 and 30oC. The effects of maternal age were not consistent at the three tested temperatures; therefore, there is a need for additional studies of the impact of maternal age on offspring quality under different biotic and abiotic conditions.

Pepper crop (Capsicum annuum,l) is considered one of the most important vegetable crops, under greenhouse conditions. This work aim to study influence of certain environmental factors (Temperature and relative humidity) on population of pepper pests i.e. aphid (Aphis gosspii), white fly (Bemisia tabaci) and spider mites (Tetranychus urticae), through growing seasons 2012 and 2 013, at two different regions (El-Dokki region, Giza governorate and El-Nobria region, Beheria governorate), Egypt. Population of white fly was the most severity compared with other pests, but population of aphid was moderately severity and population of spider mites was less severity. While, population of tested pests were more severity in El-Nobria region (Beheria governorate) than El_Dokki region (Giza governorate). However, population of tested pepper pests were increased with increasing the temperature through studied seasons. Also, population of tested pests were the most severity during the period from May to June compared with the period from January to March for to growing seasons and two regions. Population of all pepper pests were the most severity during may in El_Nobria region (Beheria governorate) during may-june in El-Dokki region (Giza governorate) Meanwhile, relative humidity was less effectively on population of tested pepper pest through this study.

The efficiency of three modifications on hive entrance to protect honeybee colonies from the serious damage occurred by the predatory hornet, Vespa orientalis Fab. Was investigated at apiary in Giza region during hornet active season, 2012. These modifications were large or small cuboid queen excluder (LCQE & SCQE, respectively) and a piece of queen excluder (QE) covered wintering entrance of the hive door, in comparison with unprotected colonies, (control). The numbers of predatory hornets attack SCQE and control colonies was significantly higher (6.8 & 6.7 hornets/col./3 min., respectively) than those attacking colonies supplied with LCQE and winter hole with QE, (6.0 & 6.3 hornets/col./3 min., respectively). The peak of hornet onslaught recorded during October and September, (9.6 & 8.8 hornets/col./3 min., respectively). Unprotected colonies were significantly lost the highest number of bees by predation, (2.39 bees/col./3 min.) in contrast with LCQE and SCQE (0.27 & 0.29 bees/col./3 min.) treatments. Sever attack resulted in extermination of control colonies within three weeks of September and colonies of QE through October. Good success was attained using LCQE and SCQE stabled over hive entrance which resulted in 100 % survival.

The identification of adults of the Calliphoridae (Diptera: Oestroidea) or blowflies is important in regard to sanitary biology, medical, veterinary, and forensic entomology. No comprehensive study of the Calliphoridae for the Kingdom of Saudi Arabia is currently available. An examination of 2,211 specimens collected from June 2010-June 2012 and literature records indicated at least 34 species of Calliphoridae are known from Saudi Arabia. Four species represent new country records, Pericallimyia greatheadi, Pollenia hungarica, Rhyncomya sinaiensis and Rhyncomya zumpti. Keys and illustrations are presented to allow determination of the adults of the 34 species. Additionally, distribution maps for these species for Saudi Arabia are provided.

Monitoring resistance in different strains of pink bollworm, Pectinophora gossypiella (Saund.) to profenofos and its relationship of some biochemical aspects
Seleman
E.
Profenofos resistance was found in field strains of the pink bollworm, Pectinophora gossypiella (Saunders) collected at late season of 2013 from four Governorates in Egypt. Resistance was high in regions where profenofos were frequently used. Resistance ranged between 31.31 and 59.60% in the tested strains. Profenofos resistance was the highest in the individuals collected from Gharbia Governorate as compared with the other field strains; whereas the lowest resistance percentage was noticed in individuals collected from Kafrel-Sheikh Governorate. Studies carried out through estimation of the detoxification enzymes activity indicated that enhanced acetylcholinesterase, alkaline & acid phosphatases and α & β nonspecific esterases as well as total protein contents were probably important mechanisms for profenofos resistance in field strains. Colorimetric assays showed a significant positive correlation between increased resistance to profenofos in strains of P. gossypiella examined and the hydrolytic enzymes activity. The information presented illustrates the importance of proper Integrated Pest Management programs (IPM) to avoid the consequences associated with improper insecticide used.

The seasonal activity of the pine scale, Leucaspis pusilla Löw (Hemiptera: Diaspididae) was conducted for two successive years (Mar., 2009 - mid-Feb., 2011) on Aleppo pine trees (Pinus halepensis) (Pinales: Pinaceae) cultivated at International Center For Training and Development at El-Amriya district, Alexandria Governorate. The obtained results revealed that, L. pusilla has two overlapping generations a year on Aleppo pine trees occurred in spring and autumn seasons. The insect population reached its maximum activity during May and October/November, peaked during May in the 1st generation and October/ November in the 2nd one. The shortest generation occurred in spring with duration of 5.5 months at 21.3 - 22.3ºC and 64.7 - 69.5%R.H. whereas the longest one occurred in autumn with duration of 7 months at 21ºC & 66.4 - 67.6%R.H. The autumn generation is the largest one (495.5 - 557.4 insects) and spring generation is smaller one (336.7 - 360.6 insects). On the other hand, the insect population reached to minimum numbers in summer season. The tested climatic factors (daily mean max. and min. temperatures as well as R.H.%) showed significant effect on the insect population in the both generations in the two years, the changes in the half monthly counts of nymph and adult populations referred to the combined effect of the tested climatic factors on the insect population in the 1st generation (spring generation) were 56.9 - 57.2% for nymphal stage; 53.7 - 65.3 for adult stage and 56.4 - 61.0% for insect population (nymph and adult) in the two years, respectively. In the 2nd generation (autumn generation) were 73.6 - 73.8% for nymphal stage; 62.4 -72.7% for adult stage and 70.7 -73.9%for insect population (nymph and adults) in the two years, respectively.

Biological aspects of the predaceous mite, agistemus vulgaris soliman and gomaa and life table parameters on three host phytophagous mite species, (Acari: stigmaeidae)
Omar
Mohamed
Mites of family Stigmaeidae are potential predators of various species of phytophagous mites through the world.The present study was conducted in Acarology Research Laboratory Plant Protection Research Institute, Dokki, Egypt. The aim of this work was to study the effect of different prey species on the biology of stigmaeid mite, Agistemus vulgaris Soliman and Gomaa. The results showed that A.vulgaris completed its life cycle in 12.56 days when fed on Tetranychus urticae Koch as compared to 12.09 and 10.75 days when fed on Oligonychus sayedi Zaher, Gomaa & El-Enany and Aculops lycopersici Massee, respectively. The maximum average fecundity (53.75 eggs/female) was recorded after feeding on O. sayedi where as after feeding on T. urticae and A. lycopersici , it was 28.43 and 21.93, respectively. Predatory mite has better life table parameters in comparison with the other prey mites. The biological aspects of the predator was as follow, Mean generation time (T) averaged 18.63, 19.18 and 15.34 days, respectively; Net reproductive rate (Ro) averaged 12.82, 24.38 and 9.81; intrinsic rate of natural increase (rm) was 0.13, 0.16 and 0.14; finite rate of increase (λ) averaged 1.14, 1.18 and 1.16 when the mite fed on immature stages of T. urticae, O. sayedi and A. lycopersici, respectively. A. vulgaris is considered a promising biological control agent against phytophagous mites.

Mosquitoes have a world-wide distribution occurring mostly in sub-Saharan Africa where they cause considerable annoyance due to their bites also an important disease vector. The study was undertaken within a six week period in Asa-Obingwu a rural community, in Abia State South eastern Nigeria, to identify the different mosquito vector species and to determine the level of vector host association using blood meal status. In determining the distribution and abundance of mosquito in the study areas, indoor residual spraying using pyrethrum was adopted. The entire Knock down mosquitoes were collected and preserved in labeled bottles accordingly. The mosquitoes were there after identified to species level using dissecting microscope. The results showed that out of 613 mosquito knocked down during the study, 485 (79.1 %) were Anopheles specie, 77 (12.6%) were Aedes specie while 51(8.3 %) were Culex specie.The meal status of the different species encountered showed that Anopheles specie were more fed 324(66.8%) followed by Culex 19 (37.3%) and the least was Aedes 9(11.7 %)specie. These results were significantly different (P<0.05). The average indoor resting density showed that 4 anopheles mosquitoes were found in every house per night as compared to Culex (0.4) and Aedes (0.6) these findings were attributed to the presence of water bodies around the residential areas which were good breeding sites for the vector. The inhabitants were mostly individuals with poor knowledge of malaria transmission and control. It is therefore advocated that government intensify efforts at educating the rural populace on the dangers posed by the presence of the vector.

Preliminary investigation were carried out concerning the occurrence of dengue vectors Aedes aegypti and Aedes albopictus in rural and urban areas of various localities of Distt Dehradun. The distribution of dengue vectors, A. aegypti and A. albopictus vary from place to place. Epidemiological interpretation of various entomological indices like house index, container index, breteau index and pupal index were carried out by WHO norms. A total of 971 houses were searched during house to house larval survey for Aedes breeding in all kinds of temporary and permanent water bodies both indoors and outdoors in rural and urban areas. Of 971 houses breeding of Aedes could be detected in 226 houses, 684 water containers were searched for Aedes breeding, out of which 93 were found positive. The over all house index (HI), Container index (CI), breteau index (BI) and pupal index (PI) were 23.27%, 13.60%, 9.58% and 5.87% respectively. All the indices were found to be higher than normally acceptable limits (WHO, 2003) and Aedes breeding was recorded in all the localities except Mussorie and found to vary from locality to locality. Dengue viruses circulate mainly between human and vector mosquitoes, and the presence of vector is a limiting factor of transmission. Therefore, spatial distribution of dengue vectors is a significant concern in the epidemiology of the disease.

S.
Adenekan
A.
Background: Malaria control is a major challenge in many endemic countries including Nigeria;implementation of evidenced-based control strategies is therefore needful in thesustainability of malaria control programme.
Method: Across-section study was designed to access perception two communities of Oyo state using pre-tested structured questionnaire.
Result: Ninety six percent of respondents reported to have heard of malaria, though majority reported mosquito as major transmitter of the infection but only 22.6% has adequate knowledge of the correct transmission route. Misconception about the causative agent of malaria is high, only 13.2% mentioned Plasmodium species as the causative agent. The knowledge about the ecology of mosquito was greatly applauded in the study area. Health-seeking behaviors and possession of insecticidal treated bet net were found to be associated with socio-economic status of individual.
Conclusion: In spite of the high knowledge about malaria demonstrated in this study, some misconceptions about transmission and symptom still exist.The need to improve the spreading of information about malaria through rural dispensaries andprimary health centers is essential for resounding success to be recorded.
