Neuroethology of Parasitoid Wasps

Predators as diverse as snakes, scorpions, spiders, insects and snails manufacture venoms to incapacitate their prey. Most venoms contain a cocktail of neurotoxins and each neurotoxin is designed to target specific receptors in the nervous and muscular systems. Most neurotoxins act peripherally and interfere with the ability of the prey's nervous system to generate muscle contraction or relaxat...

report new one genus and two species in suborder aphelenchina for fauna nematodes of iran

abstract in order to identify the plant parasitic nematodes of cucumber field and greenhouses in jiroft and kahnoj regions, during 2007 and 2008, 45 soil and root samples were collected. in this survey, 13 genus and 16 species were identified. genus ektaphelenchoides and one species of it, e. compsi and aphelenchus isomerus are reported for the first time in iran. the first species was found in...

A contribution to the sphecid wasps of Iran (Hymenoptera: Sphecidae), including first record of six species

مطالعات انجام شده در مورد زنبورهای خانواده‌ی Sphecidae توسط محققان ایرانی محدود است، اما محققان خارجی مطالعات نسبتاً زیادی در مورد زنبورهای این خانواده در ایران انجام داده‌اند. در این مقاله‌ی کوتاه ضمن بررسی اجمالی مطالب منتشر شده در مورد فون این خانواده در ایران، شش گونه برای اولین بار از کشور گزارش می‌شود.

The evolution of gregariousness in parasitoid wasps

The evolution of polyembryony in parasitoid wasps.

Polyembryony has evolved independently in four families of parasitoid wasps. We review three main hypotheses for the selective forces favouring this developmental mode in parasitoids: polyembryony (i) reduces the costs of egg limitation; (ii) reduces the genetic conflict among offspring; and (iii) allows offspring to adjust their numbers to the quality of the host. Using comparative data and ve...
