Five maize hybrids viz., yellow three ways cross 352, yellow single cross 168, white single cross 122, white single cross 10 and white single cross 128 were tried on three sowing dates viz. 1st April, 15th April and 1st May. Results showed that, population of S. cretica (eggs and larvae) was highest in early sown crop (1st April) while was least in late sown maize (1st May). Also, none of tested hybrids showed immunity or high resistance and S.C.128 hybrid was more resistant to larvae (minimum dead heart percent), while T.W.C.352 hybrid was more sensitive to S. cretica (maximum dead heart percent). Five hybrids can be arranged in ascending order according to their susceptibility (population density of eggs, larvae and infested percentages) as follow: T.W.C.352, S.C.168, S.C.122, S.C.10 and S.C.128. These results were repeated in both seasons study. Five insecticides were tested for their efficacy against S. cretica under field conditions. All treatments were found effective in reducing larvae and protecting plants compared with control. Insecticide Emamectin benzoate was found best, led to minimum number of larvae followed by Chlorantraniliprole and Lufenuron, respectively. While, radiant resulted lowest. On the other hands, Chlorantraniliprole was found best, led to minimum infested followed by Emamectin benzoate.}, keywords = {Sesamia cretica,sowing dates,Hybrids,Zea mays}, url = {https://jppp.journals.ekb.eg/article_64424.html}, eprint = {https://jppp.journals.ekb.eg/article_64424_58d8125326650acd8872b528a7a213ed.pdf} } @article { author = {Ghanim, A. and Awadalla, S. and Mosalam, A. and Nassem, Asmaa}, title = {Effect of Fallen Fruits In Peach Orchards on the Occurrence of Fruit Flies at Gharbia Governorate}, journal = {Journal of Plant Protection and Pathology}, volume = {10}, number = {10}, pages = {483-486}, year = {2019}, publisher = {Mansoura University, Faculty of Agriculture}, issn = {2090-3677}, eissn = {2090-3758}, doi = {10.21608/jppp.2019.60358}, abstract = {This experiment was carried out in Shobra El- Namla (Tanta), Gharbia governorate on peach orchard.

Latex showed LC50 of 37 μl latex/g diet after 48 hours of feeding on latex incorporated artificial diet. Larvae were continuously fed, until pupation, with artificial diet containing LC20 of latex. Feeding inhibition and accumulated larval mortality of 53 .0 ± 15% and 73 ±2.6%, respectively, were observed before pupation for the LC20 fed larvae. The incorporation of C. procera latex into the diet significantly prolonged the larval stage duration and decreased larval and pupal weight than untreated larvae.  Furthermore, latex significantly reduced relative consumption rate (RCR), relative growth rate (RGR) and efficiency of conversion of ingested food (ECI). While there were no significant effects of latex on activities of both invertase, and esterases (α and β Esterases) it showed a strong and significant inhibitory effect on α–amylase.  However, latex induced an obvious and significant increase in alkaline phosphatase activity. It is suggested that the antifeedant effect of C. procera latex could be due to the digestion inhibition through the inhibition of α–amylase activity, while a significant portion of the digested food were used by C. procera latex fed larvae for synthesis alkaline phosphatase. These results provide more evidences regarding the mode of action of the lethal and sublethal effects of C. procera latex on G. mellonella.as a model insect species.}, keywords = {Calotropis procera,latex,Galleria mellonella,Growth,Development,Nuteation,physiology}, url = {https://jppp.journals.ekb.eg/article_63674.html}, eprint = {https://jppp.journals.ekb.eg/article_63674_6d0c21ea850cf04865d241e6407e9ed1.pdf} }
