Effect of Eucalyptus citriodora and Schinus terebinthifolius essential oils on the diamondback moth and its parasitoid Trichogramma pretiosum [PDF]

open access: yesJournal of Plant Protection Research
Essential oils (EOs), from plants’ secondary metabolism, present bioactive compounds that may have insecticidal activity. Their use associated with parasitoid hymenoptera can be an alternative, however, little is known about the impact of EOs on the ...

Host and symbiont genetic contributions to fitness in a Trichogramma-Wolbachia symbiosis. [PDF]

open access: yes, 2018
The fitness effects associated with Wolbachia infection have wide-ranging ecological and evolutionary consequences for host species. How these effects are modulated by the relative influence of host and Wolbachia genomes has been described as a balancing

The evolution of gregariousness in parasitoid wasps [PDF]

open access: yes, 1998
Data are assembled on the clutch-size strategies adopted by extant species of parasitoid wasp. These data are used to reconstruct the history of clutch-size evolution in the group using a series of plausible evolutionary assumptions.
