The effect of the entomopathogenic fungus Beauveria bassiana on the biological characteristics and life table of Aphidius matricariae , a parasitoid of the green peach aphid, Myzus persicae , was studied under laboratory conditions. Aphids were first

International audience; Several hundred species of haplochromine cichlid fish have evolved rapidly in Lake Victoria. Divergent sexual and ecological selection probably played an important role in this radiation, generating divergent mating preference

International audience; In parasitoid wasps, the process of locating and selecting suitable oviposition sites is under strong selection due to the direct linkage of successful host selection and female fitness. Leptopilina clavipes Hartig (Hymenopter

International audience; We simulated a meta-population with random dispersal among demes but local mating within demes to investigate conditions under which a dominant female-determining gene W, with no individual selection advantage, can invade and

There is evidence that longevity and starvation resistance are determined by a common genetic mechanism. Starvation resistance in Drosophila strongly correlates with both fat content and longevity, and is affected by density during rearing. In this s

Theory predicts that asexual reproduction has a competitive advantage over sexual reproduction because of the twofold cost of producing males. Few systems are suitable for directly testing this prediction. In the solitary parasitoid wasp Venturia can

Species of the genus Leptopilina are larval parasitoids of Drosophilidae, mainly species of the genus Drosophila. We provide four lines of evidence (i.e. morphological descriptions, crossing experiments, ITS2 sequences and RFLP’s) to show that at l

African cichlid fishes have undergone outbursts of explosive speciation in several lakes, accompanied by rapid radiations in coloration and ecology. Little is known about the evolutionary forces that triggered these events but a hypothesis, published

This study compares the life histories of five hymenopteran species (genus Leptopilina), and aims to identify reasons why developmental time and life span are not correlated in parasitic Hymenoptera, a relationship that is present in many other taxa.

1. Six species of drosophilid parasitoids of the genus Leptopilina (Hymenoptera: Eucoilidae) exist in Europe. Laboratory experiments reveal that the fundamental niches for most of these species overlap. Field collections indicate that overlap in thei
