This study aimed to evaluate the<br />efficiency of hydrophilic silica nano-particles at 500 ppm concentration compared<br />with recommended chemical insecticide “Malathion” against <em>Callosobruchus<br />maculatus</em> Fab. (Coleoptera: Chrysomelidae) under laboratory stored<br />conditions. <em>C. maculatus</em> is a major pest of cowpeas in Egypt.<br />Hydrophilic silica-nano-particles showed that the number of <em>C. maculatus</em>,<br />mortality were 99 ± 1.2, 96 ± 3.2, 100 ±<br />0.0 and 100 ± 0.0 % six, four, two months <br />and zero time post treatment;<br />respectively, reduced to 5 ± 4.2, 12 ± 6.2 , 24 ± 3.2 and 63 ± 1.2 in case of<br />using Malathion. Biological parameters revealed decrease of egg number and seed<br />damage % with hydrophilic silica nano-particles. This investigation recommends<br />Silica nano-particles as an effective matter in control <em>C. maculatus</em><br />under laboratory condition with low damage in cowpea seeds. Also, we need more<br />study on the effect of using different degrees of temperature during using<br />silica nanoparticles on pest suppression.

A study purposed to evaluate the acute residual toxicity of six insecticides (different groups); Dursban and Malathion (OP), Chess (Selective feeding broker), Spintor (bioinsecticide), Biogard: (<em>Bacillus thuringiensis</em>) (bacteria), and Biover: (fungus) on immature stages of the predator, <em>Chrysoperla carnea</em> (Stephens) (Neuroptera: Chrysopidae) was carried out under laboratory conditions. Lethal and sub-lethal effects of the tested insecticides (4 concentrations each) on the development of the eggs (3 ages) and the 2<sup>nd</sup> instar larvae of the predator were assayed. The eggs were treated using the dipping method, while the larvae were treated using the residual film contact method. LC<sub>50</sub>, LC<sub>90,</sub> LC<sub>99 </sub>and the sub-lethal concentration (LC<sub>20</sub>) for each insecticide were estimated. Hatchability values, percentages of the treated eggs as well as percentages of larvae were calculated. Pupation and adult emergence percentages were estimated and compared with those of the untreated check to study the residual effect on the treated larvae, using LC<sub>20 </sub>of each insecticide. The dose-mortality responses of theeggs were compared in terms of differences in slopes and LC<sub>50</sub> values. Data showed that the 3-day old eggs were more tolerant to the tested insecticides than the newly ones. The mean mortality percentages of treated larvae were: 100, 100, 55, 50, and 20% for Dursban, Malathion, Biogard, Chess and Spintor, respectively. According to the classification of (IOBC/WPRS), Dursban and Malathion were classified as harmful insecticides, Biogard and Chess as moderately harmful, and Spintor as harmless insecticde.<em> C. carnea</em> larvae showed a relative tolerance to the insecticides tested as they pupated and developed successfully to the adult stage. The highest larval mortality (24%) was recorded for Dursban, while the lowest one (18%) was for Spintor compared with (10%) for the control. Statistical analysis of accumulated larval mortality indicated that there were insignificant differences among the mortality percentages in any of the studied insecticides and also between the treated larvae with each insecticide and the control. Spintor was the most suitable insecticide recommended to be used in IPM programs as it is safe for different stages of <em>C. carnea</em>.

<em>Euseius scutalis</em> developed and oviposited when provided with egg stage of <em>Parlatoria ziziphi</em>as prey under laboratory conditions of 28 ± 2°C and 70 ± 5% relative humidity (RH).<em> Euseius scutalis</em> was significantly affected by food source but a slight difference was noticed between females and males. The efficiency of the predator increased as it advanced in its development. Egg incubation period of female and male lasted 2.11 days. The life cycle lasted 8.04 and 7.32 days for female and male, respectively. The female lived for a longer period than that of the male, where longevity was 23.3 and 17.11 days for female and male, respectively. The number of prey eggs consumed per individuals was 16.11 and 10.30 eggs for total immature stages. The female predator devoured 43.81 prey eggs during the oviposition period (11.46 days) and deposited 0.91 eggs per day.

The two-spotted spider mite, <em>Tetranychus urticae</em> Koch was considered the major pest of agricultural systems. The diversity of toxicological effect of different acaricide formulations recently recommended for use were done. Behera and Dakahlia populations were tested. Results showed thatthe individual LC<sub>50</sub>s were not significantly different but Dakahlia population was considered more tolerant than Behera in hexythiazox, propargit, spirodiclofen, sulfur, abamectin and chlorfenapyr. The ratio between the LC<sub>90</sub>values of all bioassays and the high recommended field dose were relatively higher for only abamectin in Dakahlia. The lowest adult survival percentage was recorded with chlorfenapyr, 15.66%, in Beheraan detoxazole, in Dakahlia15.0%recorded by contact treatment after 72h. The percentage of the eggs that not hatched was higher for clofentezine andetoxazole in both regions about 84%, but abamectin and spirodiclofen was the lowest reduction reached 67%.The residual effect at their recommended field rate, acaricides were non-significant to each other but significantly different from control. The estimated mortality percentages in Behera ranged between 94.0 to 74.6 % for pyridaben and abamectin respectively at1 day after application, while, mortality at 12 days after application was ranged between 52.6 to 30.6 % for spirodiclofen and abamectin respectively. The total effect of the acaricide tested in the two populations was ranged between 81.69 to 64.3 % in Behera and 80.7 to 65.3% in Dakahlia.

Daily behavioral and<br />physiological rhythms in most animals are regulated by a circadian clock. In<br />the fruit fly, <em>Drosophila melanogaster</em>, this clock consists of a network<br />of about 150 cerebral neurons. Different parameters of the fruit fly circadian<br />locomotion are attributed to specific neuronal subsets and the molecular<br />rhythms of clock genes and proteins within them. To understand the clock<br />machinery, many clock mutant flies have been used. <em>yellow white</em> (<em>y w</em>) mutation in <em>D. melanogaster</em> cause impaired<br />melanisation, eye pigmentation loss, and behavioral alterations including<br />changes in circadian locomotion. This study investigates the possible molecular<br />background for these circadian alterations. Results revealed that in the output<br />pathway of the clock, the Pigment-Dispersing Factor (PDF) expression was<br />suppressed in <em>y w</em> mutant fruit flies compared to <em>Canton S</em> (<em>CS</em>) wild-type in the PDF<sup>+</sup> clock neurons. On<br />the other hand, the degradation of the PERIOD (PER) protein was significantly<br />delayed in <em>y<br />w</em> mutants and their levels was higher, especially at<br />the transition from dark to light. The combined effect of elevated PER levels<br />and suppressed PDF signaling provides an explanation for the delayed morning<br />locomotor activity peak (M) and advanced evening peak (E) of <em>y w</em> flies<br />compared to <em>CS</em>.<br />It could be concluded that mutations affecting eye pigmentation like the <em>y w</em> mutation<br />could have profound effects on the circadian regulation of behavior and their<br />underlying molecular oscillations in clock neurons. These effects reduce the<br />plasticity and robustness of the circadian clock and expose the flies to higher<br />levels of the environmental risk of desiccation.
