اثر سمیت چهار اسانس گیاهی پونه Mentha longifolia ، آویشن Thymus daenensis، بومادران زرد Achillea wilhelmsii و درمنه Artemisia hausskenechtii روی حشرات بالغ دو گونه شپشه آرد (Tribolium castaneum (Herbst و (T.confusum (Du val بررسی شد. اسانس ها با روش تقطیر با آب تهیه گردیدند. غلظت‌ها بر اساس آزمایشات اولیه برای هر اسانس تعیین شد. میزان مرگ و میر بعد از گذشت 3، 6، 24، 48 و 72 ساعت ثبت گردید. ب...
Maternal-Effect Dominant Embryonic Arrest ("Medea") factors are selfish nuclear elements that combine maternal-lethal and zygotic-rescue activities to gain a postzygotic survival advantage. We show that Medea(1) activity in Tribolium castaneum is associated with a composite Tc1 transposon inserted just downstream of the neurotransmitter reuptake symporter bloated tubules (blot), whose Drosophil...
Genetic screens are powerful tools to identify the genes required for a given biological process. However, for technical reasons, comprehensive screens have been restricted to very few model organisms. Therefore, although deep sequencing is revealing the genes of ever more insect species, the functional studies predominantly focus on candidate genes previously identified in Drosophila, which is...
The insect mushroom bodies play important roles in a number of higher processing functions such as sensory integration, higher level olfactory processing, and spatial and associative learning and memory. These functions have been established through studies in a handful of tractable model systems, of which only the fruit fly Drosophila melanogaster has been readily amenable to genetic manipulat...
Sex combs reduced (Scr), a Hox gene located in the Antennapedia complex of Drosophila melanogaster, is required for the proper development of the labial and first thoracic segments. The Tribolium castaneum genetically defined locus Cephalothorax (Cx) is a candidate Scr ortholog based on the location of Cx in the beetle Homeotic complex and mutant effects on the labial and first thoracic segment...
