Lack of phenotypic and evolutionary cross-resistance against parasitoids and pathogens in Drosophila melanogaster [PDF]
BackgroundWhen organisms are attacked by multiple natural enemies, the evolution of a resistance mechanism to one natural enemy will be influenced by the degree of cross-resistance to another natural enemy.

Background Aphids often harbor bacterial symbionts that confer resistance to biotic and abiotic stress. Previous studies have primarily examined the direct effects of symbiont infection on parasitoid success but less on aphid population dynamics under ...

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.

Why is there no impact of the host species on the cold tolerance of a generalist parasitoid? [PDF]
For generalist parasitoids such as those belonging to the Genus Aphidius, the choice of host species can have profound implications for the emerging parasitoid. Host species is known to affect a variety of life history traits.

The mechanism of the emergence of Cotesia kariyai (Hymenoptera: Braconidae) larvae from the host
At maturity, the endoparasitoid larvae of several subfamilies of the Braconidae have to emerge from inside of the host to pupate. Although the hosts hormonal milieu and the timing of larval parasitoid emergence have been studied, no report has yet ...

Infectious Behavior in a Parasitoid
Solitary parasitoid insects usually lay only one egg per host and reject already parasitized hosts, because only one offspring can successfully develop ([ 1 ][1]). Despite the constraints, superparasitism is commonly observed.
