Plant Domestication Affects the Oviposition Behavior and Performance of Ganaspis kimorum, a Parasitoid of Drosophila suzukii

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
In this study, we investigated the effects of blueberry domestication on the oviposition behavior and performance of Ganaspis kimorum, a parasitoid of Drosophila suzukii. Domestication of blueberries reduced the oviposition‐searching behavior of the parasitoid but enhanced parasitoid performance, including offspring performance. Additionally, blueberry

The changing use of the ovipositor in host shifts by ichneumonid ectoparasitoids of spiders (Hymenoptera, Ichneumonidae, Pimplinae)

open access: yesParasite, 2018
Accurate egg placement into or onto a living host is an essential ability for many parasitoids, and changes in associated phenotypes, such as ovipositor morphology and behaviour, correlate with significant host shifts.

DNA extraction from museum specimens of parasitic Hymenoptera. [PDF]

open access: yes, 2012
At the same time that molecular researchers are improving techniques to extract DNA from museum specimens, this increased demand for access to museum specimens has created tension between the need to preserve specimens for maintaining collections and ...

How Do Female Pest Tephritids Behave During Male Courtship?

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
In this paper, the female role during male courtship was described for the first time in fruit flies. Our findings show that females imitate some male behaviors and suggest that certain behaviors are associated with male mating success. Indeed, the Mediterranean fruit fly displays fewer behavioral units (i.e., shorter courtship sequences) than ...

Circumscription of the Ganaspis brasiliensis (Ihering, 1905) species complex (Hymenoptera, Figitidae), and the description of two new species parasitizing the spotted wing drosophila, Drosophila suzukii Matsumura, 1931 (Diptera, Drosophilidae) [PDF]

open access: yesJournal of Hymenoptera Research
Based on host specificity and distribution data, it has been hypothesized that Ganaspis brasiliensis (Ihering, 1905), a natural enemy of the horticultural pest spotted-wing drosophila, Drosophila suzukii Matsumura, 1931 (SWD), was composed of multiple ...

Solving the trophic puzzle: Host–parasite associations in Neotropical fig wasps associated with fig trees of section Americanae

open access: yesEcological Entomology, EarlyView.
We determined the trophic associations among fig wasp species associated with Ficus citrifolia by integrating gall morphology, the temporal sequence of wasp colonization, and oviposition behaviour. Dissection of galls produced by four gall‐inducing species at a late developmental phase enabled direct identification of occupants and inference of host ...
