A phylogenetic study of the Cynipoidea (hymenoptera)
… and relationships of the Cynipoidea with other Hymenoptera were all discussed. Finally the phylogenetic reconstruction was used to provide the first reasoned classification for the super family.

Communication in the hymenoptera : chemistry, ecology and evolution
… male European beewolves Philanthus triangulum (Hymenoptera, Crabronidae) might have evolved according to the sensory exploitation hypothesis. A three-step scenario is supported by our studies. First, a major component of the honeybee alarm pheromone, (Z)-11-eicosen-1-ol, is also found on the …

Revision of Xanthomicrogaster Cameron, 1911 (Hymenoptera: Braconidae: Microgastrinae)
Subfamily Microgastrinae (Hymenoptera: Braconidae) is one of the largest subfamilies of parasitoid wasps, both in terms of number of described species as well as estimated total number of species. Containing ~57 genera and exclusively attacking Lepidoptera, most of the diversity is concentrated …

Identifying dryinidae (hymenoptera) - auchenorrhyncha (hemiptera) host associations using phylogenetics
Dryinidae is a family of ectoparasitoid wasps with cosmopolitan distribution that exclusively preys on and parasitizes members of the suborder Auchenorrhyncha (Hemiptera). Host records of these important biocontrol agents are fragmentary because previous records have been based on tedious …

The Effects of Urban Land Use on Wasps (Hymenoptera: Apocrita)
… is intended to (1) provide a broader survey of Hymenoptera in an urban context; (2) provide new information on diversity and distribution of parasitoid Hymenoptera; (3) assess the potential for parasitoids as providers of bio-control services for urban agriculture in Cleveland, OH; (4) determine …

Electrophoretic Discrimination of Species of the Muscidifurax (Hymenoptera: Pteromalidae) Complex
The systematics of Muscidifurax (Hymenoptera: Pteromalidae), a parasitoid of the housefly, has been studied using gel electrophoresis of enzymes. Electrophoretic techniques have been perfected for the genetic analysis of Muscidifurax. These methods reveal "fixed" genetic differences between …

Ethologie des fourmis Eutetramorium mocquerysi (Emery, 1900) Hymenoptera, Formicidae, en laboratoire
The laboratory breeding study of Eutetramorium mocquerysi was conducted in an artificial fourmiliere: formicarium. The colonies were nourished with portions of insects (larvae of coleoptera, locusts, cockroaches. ..).All social insects have several morphoanatomic castes (worker dominating, workers …
