Monte Carlo Simulation of Age-Dependent Host-Parasite Relations [PDF]
The death of a biological population is an extreme event which we investigate here for a host-parasitoid system. Our simulations using the Penna ageing model show how biological evolution can ``teach'' the parasitoids to avoid extinction by waiting for the right age of the host. We also show the dependence of extinction time on the population size.

No Intersexual Differences in Host Size and Species Usage in \u3ci\u3eSpalangia Endius\u3c/i\u3e (Hymenoptera: Pteromalidae) [PDF]
Spalangia endius were collected from fly pupae, primarily house fly and stable fly, from a poultry house in Indiana. Male and female wasps did not differ within and across host species in host size usage.

Fall armyworm (FAW) preferred ovipositing on vegetative‐stage soybeans. While ‘mother knows best’ may not apply in soybean‐FAW system, muffled cues in the reproductive stage could positively influence host success. Abstract BACKGROUND While the mother knows best/preference performance hypothesis has been well tested in natural ecosystems, how these ...

Study of mating effect, hosts range and competition with the parasitoid Bracon hebetor on some behavioral and biological aspects of larval parasitoid Goniosus sp [PDF]
Laboratory studies was conducted to investigate effect of mating behavior on egg laying, host selection and competition with Bracon hebetor. The results showed that no differences in mating and egg laying behavior between mated and unmated females ...

Chemical Ecology of Egg Parasitoids Associated with True Bugs [PDF]
Parasitoids representing some 15 families of Hymenoptera develop in insect eggs; three of these families, Platygastridae (= Scelionidae), Mymaridae, and Encyrtidae, are associated with Heteroptera. Several species of heteropteran egg parasitoids are or may be important for biological pest control.

The predatory effect of the honey‐buzzard affects the reproductive performance of Asian‐hornet colonies, decreasing the density of workers over distance and time. The foraging distances of the honey‐buzzard concentrates within the first 2000 m from nest, which supports the results observed.
