The cost of being an omnivore: mandible wear from plant feeding in a true bug
It is shown for the first time that plant feeding can impose similar wear on plant-piercing animals as well as carnivorous animals. Expand
Efficacy of homemade botanical insecticides based on traditional knowledge. A review
There is some evidence that homemade botanical insecticides could contribute to reducing losses in food production, although efficacy was variable and often lower than the positive controls (synthetic pesticides). Expand
Delivering Actionable Plant Health Knowledge to Smallholder Farmers Through the Plantwise Program
ABSTRACT Delivering actionable, high-quality plant health knowledge to smallholder farmers and the extension workers who support them is a major challenge. Few farmers access information via theExpand
Manipulation of parasitoid state influences host exploitation by Diadromus pulchellus Wesmael (Hymenoptera: Ichneumonidae)
A sound understanding of species-specific reproductive biology and parasitoid–host interactions is likely required before oviposition-enhancing parasitoids states can confidently be identified. Expand
Comparative life tables of leek moth, Acrolepiopsis assectella (Zeller) (Lepidoptera: Acrolepiidae), in its native range
Leek moth pupal mortality was significantly greater on uncaged than on caged leeks, indicating an impact by natural enemies, and this pattern was consistent over all three years of study, suggesting that the pupal stage may be particularly vulnerable to natural enemies and, therefore, may be the best target for classical biological control in Canada.

Phenology, distribution, and the natural parasitoid community of the cherry bark tortrix
The larval parasitoid, Campoplex dubitator Horstmann (Hymenoptera: Ichneumonidae), was clearly dominant, representing 85% of all the parasitoids emerging from CBT hosts, and the relevance of these and other features of the CBT Parasitoid community for biological control are discussed. Expand
Pre-release analysis of the overwintering capacity of a classical biological control agent supporting prediction of establishment
This study investigated the effect of temperature on the development and overwintering capacity of the pupal parasitoid, Diadromus pulchellus Wesmael, a candidate classical biological control agent against leek moth, Acrolepiopsis assectella (Zeller) (Lepidoptera: Ac Rolepiidae) in Canada. Expand
Does parasitoid state affect host range expression
Parasitoid age had a minor effect on host range expression that was contrary to expectations, and there was an interaction between the effects of parasitoid condition and experimental design on responsiveness to low-rankedhosts: increasing non-target density in choice tests significantly altered attack rates by 10-day-old, but not by 3-day, parasitoids.
