Signaling molecules affecting patterning processes are usually proteins and rarely peptides. Two novel peptides, pedibin and Hym-346, that are closely related to one another have been isolated from Hydra vulgaris and Hydra magnipapillata. Several experiments indicate that both cause a reduction in the positional value gradient, the principle patterning process governing the maintenance of form ...
Many insects possess a sexual communication system that is vulnerable to chemical espionage by parasitic wasps. We recently discovered that a hitch-hiking (H) egg parasitoid exploits the antiaphrodisiac pheromone benzyl cyanide (BC) of the Large Cabbage White butterfly Pieris brassicae. This pheromone is passed from male butterflies to females during mating to render them less attractive to con...

باکتریهای (α-proteobacteria) wolbachia هم زیستهای درون سلولی هستند که در بافتهای تناسلی تعدادی از بندپایان یافت میشوند. القاء بکرمادهزایی در زنبورهای تریکوگراما اغلب توسط این باکتری که از طریق سیتوپلاسم تخم منتقل میشود، صورت میگیرد. در این تحقیق، آلودگی به باکتری wolbachia در 5/49، 6/3 و 5/2 درصد از افراد جمعیتهای طبیعی زنبور trichogramma brassicae bezdenko که به ترتیب از بابلسر، چمستا...
