Mate recognition and reproductive isolation in the sibling species Spodoptera littoralis and Spodoptera litura
*Correspondence: Ahmed M. Saveer, Department of Plant Protection Biology, Box 102, SE-230 53 Alnarp, Sweden e-mail: [email protected] Mate recognition is crucial for reproductive isolation and for maintaining species integrity. Chemosensory-mediated sexual communication with pheromones is an essential component of mate recognition in moths. Confronted with sex pheromone stimuli released fr...
متن کاملComparison of Amino Acid Sequences of Halloween Genes in Spodoptera litura and Spodoptera littoralis
20-Hydroxyecdyone (20E), an active form of ecdysteroid, is the key hormone in insect growth and development. To date five P450 enzymes involved in the last four steps of ecdysteroid biosynthesis from ketodiol to 20E namely Spook (Spo), Phantom (Phm), Disembodied (Dib), Shadow (Sad) and Shade (Shd) related to ecdysteroid biosynthesis, are identified and the character of last four enzymes is well...
متن کاملبررسی اثرات بیمارگری سه نوع نوکلئوپلی هیدرو ویروس، Spodoptera littoralis NPV، Helicoverpa armigera NPV و Spodoptera litura NPV روی مراحل زیستی پروانه برگخوار مصری پنبه Spodoptera littoralis
در این تحقیق قدرت بیمارگری سه ویروس Spodoptera littoralis NPV، Helicoverpa armigera NPV و Spodoptera litura NPV در سه غلظت مختلف 10۲×6، 104×6 و ۱۰۶×۶ OB در میلی‌لیتر روی لاروهای ۵ روزه کرم برگخوار مصری پنبه (Spodoptera littoralis) در دمای ۲5 درجه سلسیوس روی غذای مصنوعی بررسی شد. بیشترین طول دوره لاروی با 19.7 روز مربوط به ویروس H. armigera در غلظت ۱۰۴×6 OB در میلی‌لیتر بود که با بقیه تیمارها اخ...
متن کاملMechanisms of Gustatory Coding in Spodoptera Littoralis
Adult Lepidoptera use their antennae to probe their distant and proximate environment with sensory organs which detect volatile and contact chemicals. In this work, we have investigated the role and the sensitivity of antennal contact chemoreceptors of Spodoptera littoralis. Adults of both sexes have long and filiform antennae composed of about 70 flagellomeres. Each flagellomere bears six tast...
متن کاملDetoxification System in Spodoptera littoralis against Abamectin
Biochemical and histological analysis were performed on 4 larval instar of the cotton leaf worm Spodoptera littoralis to determine the effect of abamectin (LC50) on the biomarkers acetylcholinesterase (AChE), glutathione S-transferase (GST), α-, βesterase and mixed function oxidase (MFO).Biochemical analysis showed a severe reduction in the enzymatic activities of GST and α-esterase, as compare...
