We studied the morphology of the ovipositor of Platygaster diplosisae (Hymenoptera: Platygasteridae) and Aprostocetus procerae (= Tetrastichus pachydiplosisae) (Hymenoptera: Eulophidae), two parasitoids associated with the African rice gall midge (AF

We investigated the female reproductive system of Platygaster diplosisae (Hymenoptera: Platygastridae) and Aprostocetus procerae (= Tetrastichus pachydiplosisae) (Hymenoptera: Eulophidae), two parasitoids associated with the African rice gall midge,

In solitary parasitoid species, superparasitism incurs a high cost because only one individual can emerge per host. While avoiding already-parasitized hosts seems advantageous, it requires an ability to discriminate between parasitized and unparasiti

Chez les parasitoïdes solitaires, un seul individu émerge par hôte, aussi les femelles devraient rejeter ceux préalablement parasités. Cependant, lorsque les hôtes sains sont rares, le superparasitisme devient avantageux et les femelles devraie

The tubercles present on the egg chorion of the carrot weevil, Listronotus oregonensis (LeConte), are described and their variability in density quantified between females. Tubercle density varied by a factor of six between females, from 19 000 to 11

Three Nearctic and six Palearctic populations of Delia radicum L., two Palearctic populations of D. antiqua Meigen, and one Palearctic population of D. floralis Fallen were used to evaluate the range of intraspecific variation in the chorionic ultras

When attacked by herbivorous insects, many plants emit volatile compounds that are used as cues by predators and parasitoids foraging for prey or hosts. While such interactions have been demonstrated in several host–plant complexes, in most studies
