Research Interests Related to this Project:
Insect pests of field and
horticultural crops, particularly pests of cruciferous crops (swede midge,
cabbage seedpod weevil, crucifer flea beetle, cabbage maggot, diamondback moth)
and invasive species (swede midge, soybean aphid, multicoloured Asian
ladybeetle). Factors affecting population dynamics and success of insect pests.
Manipulation of insect-plant
interactions to achieve pest management with reduced reliance on pesticides.
Development of integrated pest management programs, including optimization of
monitoring protocols particularly using pheromones. Elucidation of plant cues
used in insect host finding and selection and defensive host plant compounds.
