A Comparative Functional Approach to the Host Detection Behaviour of Parasitic Wasps. 1. A Qualitative Study on Eucoilidae and Alysiinae [PDF]

open access: yes, 1985
We studied host detection behaviour in Alysiinae (Braconidae; Ichneumonoidea) and Eucoilidae (Cynipoidea), the larvae of which are endoparasitoids of fly larvae and in- vestigated whether this behaviour is determined by their descent or can be considered

Endosymbiont-free ants: Molecular biological evidence that neither Wolbachia, Cardinium or any other bacterial endosymbionts play a role in thelytokous parthenogenesis in the harvester ant species, Messor barbarus and M. capitatus (Hymenoptera: Formicidae)

open access: yesEuropean Journal of Entomology, 2013
Thelytokous parthenogenesis is a type of sex determination in which females are produced from unfertilized eggs. Genetic and endosymbiont-induced forms of thelytoky have been described in the Hymenoptera. Our study has revealed that Wolbachia, Cardinium,

Strong diel variation in the activity of insect taxa sampled by Malaise traps

open access: yesEcological Entomology, EarlyView.
Malaise traps sampled different communities during mornings (06:00–12:00), afternoons (12:00–16:00), evenings (18:00–22:00), and nights (22:00–06:00), highlighting the difference in diel rhythm between taxa. The highest diversity and abundance of insects were found during afternoons, the lowest diversity during night, and the lowest abundance during ...
