Pairs of females of the parasitoid waspNasonia vitripennis were videotaped with one or two hosts. The presence of an additional host decreased the number of interactions between females but had no measured effect on the nature of the interactions, i.

Female Nasonia vitripennis lay fewer eggs and increase the proportion of male offspring when ovipositing in hosts that have been previously parasitized compared with unparasitized hosts. This study examines the location and nature of the cues that fe

One of the better-studied sex ratio theories is local mate competition (LMC) theory, first developed by Hamilton in 1967 (for reviews see Chamov, 1982; Waage, 1986; King, 1987). LMC models assume a subdivided population structure with emergence and t

In many species of insect parasitoids, adult females mature eggs as they search their environment for hosts. In such species, the number of mature eggs, at the point of finding a host, is a function of the interhost time and the rate of egg maturatio

Ovipositing insects face at least four decisions: 1) what hosts to utilize, 2) where to search for them, 3) what clutch size, and 4) what sex ratio to produce on a host. Historically, study of these phenomena has focused on elucidating the proximate

Many insects oviposit on food patches (e. g., hosts) that represent a finite resource. Competition for food may occur among the developing progeny with the effect of reducing their survivorship, size, and/or some other aspect of fitness. Here a simpl

An extrachromosomal factor, termed son-killer (sk), affects the sex ratio in a parasitoid wasp, Nasonia (=Mormoniella) vitripennis. The factor is maternally transmitted and alters the secondary sex ratio of an infected female through mortality of app

The son-killer (sk) trait in the parasitoid wasp, Nasonia vitripennis, causes the production of very female-biased sex ratios through the mortality of males. Some 80% of all male eggs fail to hatch. The trait is both maternally and contagiously trans
