From the study, it was obvious that the different biological aspects (incubation period, life cycle, longevity and life span) of the predator were significantly affected by feeding on the different diets. When the two preys were compared as food, Collembola showed a higher fecundity source than using of free living nematodes as rearing food, where the number of deposited eggs of the predator was 39.11 eggs at 25 ºC, but the free living nematodes as diet was the lowest favorable one, where the predator female deposited 33.05 eggs at 35 ºC<strong>.</strong> Generally, Collembola proved to be the more suitable prey as resulted in more deposited eggs and longer life span.Egyptian Society of Biological SciencesEgyptian Academic Journal of Biological Sciences.

Results revealed that the combined effect of the three weather factors (<em>i.e.</em> maximum and minimum temperatures and relative humidity) did not fully explained the variance in the population density over time. Explained variance (EV) was 19.98, 62.23, 60.62 and 59.7 % for tomato, eggplant, pepper and potato plants, respectively.
Considering plant phenology as plant age (X) (presented by three degree polynomial equation, Y= a + b<sub>1</sub>X+ b<sub>2</sub>X<sup>2</sup>+ b<sub>3</sub>X<sup>3</sup>) revealed the most relation to the variance in population. EV was 49.67, 90.58, 76 and 84.22% for tested plants, respectively.
The added effect of weather factors to the plant age revealed EV as 74.32, 92.24, 83.45 and 94.02% for tomato, eggplant, pepper and potato plants, respectively. These added values did not seem to be significant.
These results do not eliminate the effect of weather factors on the population dynamics. Under laboratory conditions; these factors may reveal a great deal of effect. Under field conditions these factors firstly affect the plant growth which makes the plant more palatable for infestation. So plant phenology as plant age took over the effect of weather factors mathematically.Egyptian Society of Biological SciencesEgyptian Academic Journal of Biological Sciences.

The exposed virgin and mated queens did not affected by different low doses of radiation (20 - 200 rad), except the number of sealed brood cell produced by irradiated virgin queens was decreased at dose 200 rad, high dose of irradiation (400 rad) caused a complete died in virgin queens while mated queens irradiated by 400 rad produced significant low numbers of sealed brood.
Bee honey production was significantly decreased only when virgin or mated queens irradiated with high dose (400 rad).
No significant changes in the measurement of workers appendages, such as flagellum, hind wings, fore and hind legs as a result of exposing virgin queens to doses between 20 and 200 rad, except fore wing reduced in length and width only at dose 200 rad. In case of mated queens, the above mentioned measurement did not affected at doses between 2o and 200 rad while significant decreased in the morphological measurement was occurred at dose (400 rad).Egyptian Society of Biological SciencesEgyptian Academic Journal of Biological Sciences.

And <em>Tetranychus urticae </em>(Koch) and on yield of this plant, were studied during two successive seasons (2014 and 2015). The degree of infestation by <em>A. gossypii </em>and <em>B. tabaci </em> increased significantly by delaying planting date, as cucumber plants cultivated in the earliest planting date (August, 1st) were attacked by the lowest numbers and highest weight of cucumber fruits, while the plants of the latest planting date (September, 12<sup>th</sup>) were more liabled to insects infestation with lowest weight of cucumber fruits. The results showed that, the mean rate of infestation with <em>A. gossypii</em> were (5.1, 9.2 and 11.9 individuals/leaf) during 2014 season and (5.5, 10.6 and 12.4 individuals/ leaf) during 2015 season for the three tested dates, respectively. So, the mean number of infestation with <em>B. tabaci </em> were (8.5, 15.4 and 13.6 nymphs/ leaf) during 2014 season, (7.8, 13.7 and 12.2 nymphs/ leaf) during 2015 season for the three dates, respectively. also, the highest weight of cucumber yield (20.5 and 19.7 kg/ 100m<sup>2</sup> in the two seasons, respectively) was obtained. On the contrary, the populations of <em>T. tabaci</em> and <em>T. urticae </em>increased significantly with the early planting date compared with cucumber plants cultivated in the latest planting date during the two seasons. Therefore, it was concluded that, the planting date was effective on the rate of infestation with pests and yield of cucumber plants.Egyptian Society of Biological SciencesEgyptian Academic Journal of Biological Sciences.

As a result of experiment and investigation on the population of mites inhabiting soil underneath Cotton (<em>Gossypium barbadense</em> L.) in Giza Governorate, (Kerdasa region) during April to September 2014 and 2015 to study the effect of applying lay soil with the rice straw as organic wastes with the inoculation with Humic acid both separately or together on the population of different soil mites. The obtained results revealed the presence of 17 different mite species belonging to 11 families related to four suborders, Prostigmata (Actinedida), Mesostigmata (Gamasida), Astigmata (Acaridida) and Cryptostigmata (Oribatida) associated with soil of cottonplants treated with different types of fertilizers. The percentage of collected four soil mites suborders, the actinedids were higher in the abundance inhabiting cotton plantssoil in comparison with other three collected mite groups, followed by oribatid mites, followed by acaridid mites but the gamasid mites abundance was the lower category in all three tested methods of fertilization. The obtained data demonstrated that the mean number of collected mites in case of using recommended + humic acid fertilization method was higher than those recorded in recommended only and in case of recommended + humic + rice collectively. The study also indicated that the collected different mites during 2015 cultivated season were higher in number than those obtained during the first season 2014.

In medium mature mango variety there were three one peak at the beginning of August and two peaks at late of August and September during the two successive seasons, respectively. Meanwhile, in case of late-mature mango varieties only one peak at the beginning and end of October were recorded in the two successive seasons, respectively.

In addition, the simple correlation during the second seasons between the maximum temperature and CTD of <em>B. zonata</em> was positive significant in early variety. While the medium-mature mango varieties, was significant between the maximum temperature and CTD number of <em>B. zonata</em> in medium mature mango variety during the two successive seasons , while the minimum temperatures and CTD number of <em>B. zonata </em>were significant and high significant during the two successive seasons, respectively. On the other hand, the simple correlation during the two seasons between relative humidity all tested mango varieties was insignificant and However late mango variety were insignificant between the maximum and minimum temperatures and CTD number of <em>B. zonata </em>.

Hematite nanoparticles were synthesized by a simple hypothermal method. The obtained nanoparticles average size was below 50 nm. TEM images determined the size and morphology of nanoparticles. Serial concentrations were applied on mosquito larvae. It was found that LC<sub>50</sub> of hematite nanoparticles after 48 hours of treatment was 5.6997 ppm. The obtained results added a new weapon to control mosquitoes.
