Mixed sex allocation strategies in a parasitoid wasp

Oecologia, 1997
The sex allocation strategy of the parasitoid Laelius pedatus (Hymenoptera: Bethylidae) on different-sized hosts was investigated. The wasp lays from one to five eggs, and clutch size increases with host size. On the smallest hosts, single male eggs are laid, while on slightly larger hosts single female eggs are laid.

Early memory in the parasitoid wasp Nasonia vitripennis

Journal of Comparative Physiology A, 2015
We studied early memory in Nasonia vitripennis, a parasitoid of fly pupae and emerging model organism for ecological questions in the context of learning. After associative training consisting of one drilling experience in a host in the presence of cinnamon, females showed a preference to cinnamon for at least 24 h.

Reproductive Strategies in Parasitoid Wasps

The American Naturalist, 1973
In an effort to explain different reproductive strategies among parasitoid wasps, differences in potential fecundity of members of the family Ichneumonidae were compared in relation to the availability of the host and the probability of survival of the parasitoid once it was associated with the host.

Spermatogeny as a life-history index in parasitoid wasps

Oecologia, 2005
Reproduction is a major life-history trait but it has been studied mostly in relation to female reproductive effort. Recently, an ovigeny index using the proportion of oocytes ready to be oviposited at eclosion has been proposed for female insect parasitoids. Here, we propose a spermatogeny index for male parasitoid wasps. Prospermatogenic species have

Mating systems of parasitoid wasps

1997
ABSTRACT Parasitoid wasps are a large group of hymenopteran insects whose larvae develop by feeding on the bodies of other insects. The spatial distributions of both the hosts and the parasitoid larvae influence the mating systems found in these wasps.

Sperm stock and mating of males in a parasitoid wasp

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, 2007
AbstractHymenoptera are haplodiploid insects, consequently sex ratio depends on female's sperm management which itself arises from the reproductive capacity of neighbouring males. To study the influence of ageing on male reproductive potential, laboratory experiments were conducted on Dinarmus basalis (Hymenoptera, Pteromalidae) males, a tropical wasp ...

Short Interval Time Measurement by a Parasitoid Wasp

Science, 1987
The number of eggs laid by the parasitoid wasp Trichogramma varies with host volume. The duration of the wasp's initial transit across the host surface during host examination is used to determine the number of eggs laid.
