So what's the problem?
The cabbage seedpod weevil, Ceutorhynchus obstrictus, is a widely distributed pest of cruciferous crops in Europe and North America. Accidentally introduced from Europe, the weevil was first discovered in British Columbia, Canada, about 80 years ago, and has since spread to other parts of western and eastern North America. Since its arrival in North America, the weevil has caused substantial economic losses in canola crops in the Canadian prairie provinces of Saskatchewan and southern Alberta. In eastern Canada, the occurrence of C. obstrictus is regarded as a threat to canola seed production.
What is this project doing?
Bioclimatic simulation models, also known as bioclimate envelope or ecological niche models, have been applied successfully to predict the distribution and the extent invasive insect pests have managed to establish in new environments. To a much lesser extent bioclimatic models have been developed to predict the potential areas where insects considered for classical biological control may be successful against invasive pests. The objective of our study is to collect European distribution data for Trichomalus perfectus to develop bioclimatic models, predicting the potential distribution and abundance of the parasitoid in North America.
