Effect of Insect Infestation by Macrosiphum rosae L. on the Vase Live Period of Rose Flowers under Greenhouse Conditions
This study was carried out to study the effect of insect infestation by Macrosiphum rosae L.on the vase life period on the rose flowers under greenhouse conditions at two locations International Garden (Cairo Governorate) and El-Orman Garden, (Giza Governorate) under glasshouse conditions during successive seasons 2018. This is because vase life period is a very important parameter in cut flowers. And there are many factors affected on the vase life period. Therefore this study divided into two parts, first part studied the effect of insect infestation by M. rosae on the vase life period of rose flowers after picking. Second part studied the effect of insect infestation by the same insect on the internal components of the rose flowers which correlated with vase life period of these flowers such as total sugar and total protein. Results showed that the infestation by M. rosae reduced the vase life period of rose flowers after picking at the infested rose flowers compared to control (which non infested by the same insect). Also, results showed that the infestation by M. rosae reduced total sugar and total protein at the infested rose flowers compared to control. Lastly, results showed that the infestation by M. rosae changed the number and arrangement of the protein banding patterns (amino acids) of infested rose flowers petals compared to control.

Ecological Studies of Certain Piercing-Sucking Insects Infesting Squash Plants and Relation with Their Chemical Constituents
The homopterous insects are considered polyphagous pests on some cucurbitaceous crops. The objective of aim study was to survey the aphids, leafhoppers and whitefly insect species infesting certain varieties of squash plants i.e.(hybrid Otto, hybrid Daphne and hybrid Aziad) and also to study the seasonal abundance of the dominant species as well as to evaluate the effect of different varieties and their chemical constituents on the population density of the aforementioned homopterous insects during the studying period. The present experiments were carried out at the experimental farm belonging to the faculty of agriculture , zagazig university during 2016 and2017 seasons. The least susceptible variety of squash was Aziad hybrid variety, while the highest susceptible variety was Daphne hybrid variety and the certain chemical constituents in all tested varieties were associated with the insects infestation. The resistance variety should be used as an effective factor in integrated pest management programs which played an important role in depressing the population of the tested insects.

Impact of Land Reclamation on the Diversity of Darkling Beetles, (Tenebrionidae) in Arid Ecosystem of El-Kharga, New Valley Governorate, Egypt
The present study aimed to assess the impact of land reclamation on the distribution, diversity and monthly occurrence of darkling beetles (Tenebrionidae) in El-Kharga, New Valley Governorate, Egypt. Beetles were sampled with pitfall traps over a 6-month, from September 2015 to February 2016. Four different reclaimed sites were selected site I, site II, site III and site IV. The totals of 4725 collected beetles belong to 7 species; Akis elevata Solier , Prionotheca coronata Olivier, Mesostena angustata Fabricius, Trachyderma hispida (Forskal), Akis reflexa Fabricius , Pimelia arabica Klug and Scaurus puncticollis Solier. The abundance of recorded beetles differed significantly in the four studied sites. The highest density of total beetles was recorded at long period reclaimed site; the site I (1.68±1.7 individual/day*trap). P. coronata recorded the highest density (1.85±1.66 individual/day*trap) among the seven collected species. Results indicated monthly variations in the density of the beetles in the studied sites. A. elevata, P. coronata, M. angustata and S. puncticollis showed a significant increase in October. Canonical correspondence analysis revealed that the abundance and diversity of beetles mostly related to soil pH followed by wind velocity and relative humidity. The results indicate that land reclamation led to variations in the community of tenebrionids.

The Biological Role of Cymbopogon proximus Leaf Extracts against the Malaria Vector, Anopheles pharoensis
Due to the increased insecticide resistance, control of mosquito vector encounters a number of major difficulties. In this respect, searching for new compounds from nature for their insecticidal activities may offer an effective tool for mosquito vector control. In this study the biological activity, reproductive potential, and repellency effect of methanolic, aqueous, and petroleum ether extracts of C. proximus against the malaria mosquito, An. pharoensis was evaluated. Based on LC50 values, the toxicity may be arranged as the following: petroleum ether extract (LC50 = 200.1ppm) > methanol extract (LC50 = 216.1ppm) > aqueous extract (LC50 = 848.6ppm). The biological activities were significantly (P<0.01) affected by different tested extracts, especially at higher concentrations. The female fecundity and the egg-hatchability were remarkably decreased in a concentration-dependent manner. In addition, the repellency percentages were influenced by tested extracts at any concentration used and the highest repellent action was recorded for methanol extract followed by petroleum ether extract. In conclusion, these findings may contribute insight into the possibility of a novel insecticidal development for use in mosquito control programs.

Feeding Rate and Reproductive Performance of Three Mosquito Species as Influenced by Different Blood Meal Sources
The present study evaluated the effect of different blood meal sources (human volunteer, pigeon, guinea pig and Egyptian mastigure) on feeding rate and reproductive performance of laboratory colonizedCulex pipiens L., Anopheles sergentii Theobald and Culex antennatus Becker mosquitoes during two sequential gonotrophic cycles. The obtained results showed that, mosquitoes tested exhibited a special feeding rate to human blood, as the mosquitoes fed on human blood exhibited higher feeding, fecundity and fertility rates than those fed on either type of blood sources. Concerning with feeding rates, the highest percentages of engorged females during a first blood meal (82.3, 88.1 and 86.3) were recorded when Cx. pipiens, An. sergentii and Cx. antennatus females fed on the pigeon and human hosts. Meanwhile, the highest percentages of engorged females during second blood meal (88.4, 93.5 and 92.7) occurred when Cx. pipiens, An. sergentii and Cx. antennatus females fed on the human host, respectively. Also, fecundity and fertility rates of mosquitos fed on different hosts were varied between gonotrophic cycles, as at the first gonotrophic cycle fecundity and fertility of tested mosquitoes were greater than those at the second gonotrophic cycle. In addition, feeding on human blood recorded higher fecundity and fertility rates in tested mosquito species as compared with feeding on other hosts.

Effect of Magnetic Power and Radiant Compound on Some Biological and Biochemical Aspects of Earias insulana (Boisduval) (Lep.: Noctuidae )
Under laboratory conditions, the spiny bollworm, Earias insulana (Boisd.) pupal stage of laboratory strain were exposed to three magnetic levels (2.0, 10.0 & 24 mt) and half recommended compound of radiant, to study some aspects of the pest act in biological and biochemical assays as affected by the treatments used.
The results showed that the exposed of one-day old pupae for the three MFs and Radiant (compound) elongated the pupal duration of E .insulana compared with control. The pupal durations were 9.6 , 12.6and 11.3 days/ pupae when exposed to three magnetic levels (2.0, 10.0 & 24.0 mt), respectively, and 12.6 days/ pupae with Radiant, compared with 8.3 days in control. The adults' emergence percentages were decreased to 89, 86, 77.0 and 67 % for three magnetic fields (MFs) and Radiant, respectively, compared with 98% for control.
Data obtained of E. insulana adult resulted from pupal stage treated with MFs or Radiant, revealed that increasing in pre-oviposition and post-oviposition period in the all treatments used; but the vice direction happened with oviposition period. It were 9.3, 7.3 5.6 and 8.2 compared with 12.5 days in control.
At the same times, the total eggs laid /female and hatchability percentages in adults resulted from all treatments were highly significantly affected compared with the untreated adults. These data indicated that the high decreased in number of eggs laid by females was estimated by 116.0, 79.9 and 132.0eggs, when exposed to magnetic power (MF2 &3) (10.0 & 24.0 mt), and radiant, respectively, compared to 216.0 eggs in control. In addition to the above, when sequence treatment adult resulted from pupal stage treated with 10.0mt (MF1) to a same power magnetic or fed on sequence fed on half recommend radiant cussed high reduction in number of eggs laid by females approximately from 2 to 4 times than control. some biochemical analyzes were performed to determine the som biochemical effect of the magnetic field on adults of E. insulana. The results showed high decreased estimated in levels of some key biochemical such as total proteins, total lipid and total carbohydrates contents that may be reflect the decrease in activities, also led to reduction in total eggs laid and decreasing in longevity adults.

The Effect of Temperature Regimes and Tissue Types on The Development of Chrysomya megacephala Larvae (Diptera: callophoridae).
This study investigated the effects of three temperature regimes representing several specific development conditions of this blowfly: (25.7, 28.4and 30.6oC) and tissue types. Furthermore, Chrysomya megacephala colonies were reared on three different food sources (all rabbit carcasses, Liver and muscles) on the development of C.megacephala as important forensic fly, and their possible implications to calculate the postmortem interval (PMI). The results showed that the mean durations period from egg to adult eclosion of C. megacephala when reared on control rabbit at 25.7, 28.4 and 30.6 oC were 303.5, 217 and194.5 hrs, respectively. In addition, the mean duration period from egg to adult eclosion when the larvae reared on liver tissue at 25.7, 28.4and 30.6oC were 275.5, 205.5 and 188.5 hrs, respectively. Moreover, The Larvae of C.megacephala reared on muscle tissues from rabbit carcasses, the mean duration from egg to adult eclosion at 25.7oC 28.4oC, and 30.6oC were 293, 214.5 and 192.5 hrs, respectively. From the previous results, it is obvious that the mean duration in larvae reared on control rabbit carcasses was longer than those fed on muscle which longer than those reared on the liver at all temperature regimes.
