<span style="color: windowtext;">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, <em>Sitophilus oryzae</em> 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 <em>Sitophilus oryzae</em> 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 <em>Sitophilus oryzae</em>. 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.</span>Egyptian Society of Biological SciencesEgyptian Academic Journal of Biological Sciences.

The results indicated that the infestation rate of <em>B. tabaci </em>and <em>T. tabaci</em> increased on cucumber leaves more than kidney bean. On the contrary, kidney bean was suitable host to development of aphid and <em>T. urticae</em>. 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.

Box 22491, Riyadh 11495,
Saudi ArabiaJournal Article20180910House 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 <em>Musca domestica</em> (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 <em>Aspergillus </em>spp. (66%). <em>Penecillium</em> spp. (14%), <em>Fusarium</em> spp. (11.3%), <em>Alternaria</em> spp. (6%) and among the filamentous fungi, (8.6%) of the isolates as <em>Microsporum gypseum </em>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.Egyptian Society of Biological SciencesEgyptian Academic Journal of Biological Sciences.

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 (r<sub>0</sub>) 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 r<sub>0</sub> 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.Egyptian Society of Biological SciencesEgyptian Academic Journal of Biological Sciences.

F.AliPlant Protection Department, Faculty of Agriculture, Al-Azhar University, Cairo, EgyptJournal Article20180910Predatory potential of <em>Chrysoperla carnea </em>(Stephens) was studied on different larval instars of <em>Phyllocnistis</em><em> citrella</em> (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 <em>P. citrella</em> affected predator biology with different degrees. It had no significant effect on incubation period of <em> C. car</em><em>nea</em> eggs females, pupation period, adult longevity and pre-and post - oviposition periods. On the other hand, it had significant effect on <em>C. carnea</em> larval period and its survival, female fecundity and eggs fertility. In general, third instar larvae of<em> P. citrella</em> was the most preferred prey for <em>C. carnea</em>. The results illustrate the potential importance of prey resources (life stage) on <em>C. carnea</em> population growth and indicate that <em> C. carnea</em> has considerable potential for the biological control of <em>P. citrella.</em>Egyptian Society of Biological SciencesEgyptian Academic Journal of Biological Sciences.
