Female antennal sensilla of Epidinocarsis lopezi and Leptomastix dactylopii (Hymenoptera: Encyrtidae), parasitoids of pseudococcid mealybugs
Antennal sensilla were compared in females of two encyrtid Hymenoptera, Epidinocarsis lopezi and Leptomastix dactylopii, parasitoids of adults and larvae of Pseudococcidae. The external morphology of… Expand

Antennal sensilla of hymenopteran parasitic wasps: variations linked to host exploitation behavior
Parasitoid wasps lay their eggs in or on the body of their hosts, mostly arthropods. This paper presents the antennal sensilla used by female parasitoids to locate and evaluate these hosts. A variety… Expand

Physiological costs of cold exposure on the parasitoid Aphidius ervi, without selection pressure and under constant or fluctuating temperatures
The aim of this study is to evaluate the physiological costs and the consequences on fitness of cold exposure on the parasitoid Aphidius ervi (Hymenoptera: Aphidiinae) under non-lethal conditions. We… Expand

Impact of change in winter strategy of one parasitoid species on the diversity and function of a guild of parasitoids
AbstractThe rise of temperatures may enable species to increase their activities during winter periods and to occupy new areas. In winter, resource density is low for most species and an increased… Expand

Effect of low temperature exposure on oviposition behaviour and patch exploitation strategy in parasitic wasps
Learning of olfactory and gustatory cues occurs throughout the adult stage of parasitoids, particularly during host location and patch exploitation. A loss of learning capacities could affect both… Expand

Intra- and interspecific host discrimination in two closely related egg parasitoids
Intraspecific host discrimination is frequently found in solitary parasitoids, but interspecific host discrimination, where female parasitoids recognize hosts already parasitized by females of other… Expand

Patch leaving decision rules in parasitoids: do they use sequential decisional sampling?
Within the framework of optimal foraging theory, models assume that parasitoid insects are able to evaluate the quality of the patch in which they are currently searching for hosts and the travel… Expand

Intraspecific hyperparasitism in a primary hymenopteran parasitoid
In solitary parasitoids, in which only one individual can emerge per host, the adaptive value of conspecific superparasitism is a function of the survival probability of the egg laid by the… Expand

Behavioural consequences of cold exposure on males and females of Aphidius rhopalosiphi De Stephani Perez (Hymenoptera: Braconidae)
Cold storage of insect parasitoids is currently used before mass release in the field in biological control programmes. The physiological consequences of constant cold storage are known in various… Expand

The response of life‐history traits to a new species in the community: a story of Drosophila parasitoids from the Rhône and Saône valleys
In the present study, we investigated the evolution of life-history traits in the main species of a community, after the arrival of a new competitor. Two parasitoid species, Leptopilina heterotoma… Expand
