The ichneumid wasps (Hymenoptera: Ichneumonidae) have essential role in biological control of insect agricultural and forest pests. A list 17 species 14 genera these parasitoids collected from different regions Iran is given. All them are new for the fauna country.

Drosophila melanogaster Meigen, 1830 has served as a model insect for over a century. Sequencing of the 11 additional Drosophila Fallen, 1823 species marks substantial progress in comparative genomics of this genus. By comparison, practically nothing is known about the genome size or genome sequences of parasitic wasps of Drosophila. Here, we present the first comparative analysis of genome siz...

Many parasitic wasps (parasitoids) exploit volatile organic compounds (VOCs) emitted by herbivore-infested plants in order to locate their hosts, but it remains largely unknown which specific compounds within the volatile blends elicit the attractiveness to parasitoids. One way of studying the importance of specific VOCs is to test the attractiveness of odor blends from which certain compounds ...

Many insects defend themselves against predation by being distasteful or toxic. The chemicals involved may be sequestered from their diet synthesized de novo in the insects’ body tissues. Parasitoid wasps are a diverse group of that play critical role regulating host insect populations such as lepidopteran caterpillars. successful parasitization caterpillars parasitoid is contingent upon aptitu...

Different assemblages of parasitoids may attack a given host species and non-random distribution patterns in parasitoid have been reported on various occasions, resulting co-occurrence at the population, colony, or even individual levels. This is case for different closely related eucharitid wasps (a family specialized ant parasitoids) sharing similar niches co-occurring same Here we reviewed a...

Abstract Habitat loss is a primary driver of biodiversity decline, but differences in species responses to habitat from local landscape scales are poorly understood. Trophic level, food and specialization have been suggested be important predictors loss, diversity scale. Using cavity‐nesting communities bees, wasps their parasitoids on calcareous grasslands as model system allowed us compare di...

Title of Document: THE ROLE OF HOST-PLANT SPECIES IN THE DIFFERENTIATION OF SYMPATRIC POPULATIONS OF HYMENOPTERAN PARASITOIDS. Raul F. Medina, PhD, 2005 Directed By: Professor, Pedro Barbosa, Department of Entomology The biology and ecology of insect parasitoids is strongly influenced by the hostplant species on which their herbivorous hosts occur. Hymenopteran parasitoids in particular, presen...

Cuticular hydrocarbons from the ponerine ant Ectatomma ruidum Roger and a highly integrated eucharitid myrmecophile, Kapala sulcifacies (Cameron), associated with it, have been characterized. Ninety hydrocarbons were identiÞed from the ant, 55 hydrocarbons from the female wasp and 54 hydrocarbons from the male wasp. The wasps and ants share 40 hydrocarbons. These shared 40 hydrocarbons represen...
