Quantitative genetics of preference and performance on chickpeas in the noctuid moth, Helicoverpa armigera
Article Abstract:
A study investigates the potential of a generalist herbivore to respond to a novel resistant host by estimating the heritability of larval performance in the noctuid moth, Helicoverpa armigera, on a resistant and a susceptible variety of the chickpea, cicer arietinum, at two different life stages. No genetic correlation was found between larval performance and oviposition preference, indicating that female moths do not choose the most suitable plant for their offspring.

Distribution of Wolbachia among the guild associated with the parthenogenetic gall wasp Diplolepis rosae
Article Abstract:
Organisms with a symbiotic relationship to the bacterial genus Wolbachia are likely to go from one host lineage to another on a regular basis. One possible transmission route is as parasites. In the guild associated with Diplolepis rosae, parthenogenetic gall wasps, these relationships of specialized parasitoids and inquilines have been studied. In some of the strains it could be seen that parasitoids did not acquire Wolbachia from their host.
