Following on the discussion session on insect rearing at the XII International Symposium on Biological Control of weeds, I have set up a discussion forum on insect rearing. Please click here to try it out, and let me have your feedback! Go to the forum
Work is under way on screening new biological control agents for common tansy at CABI Switzerland. Canadian funding for this project has now been approved by ACAAF (Advancing Canadian Agriculture and Agri-food) and the Agriculture Development Fund (Saskatchewan) , with additional support from EnCana Corporation and Enbridge Pipelines.
Several potential biological control agents have already been collected including the moth
Isophrictis striatella, the chrysomelid Cassida stigmatica, and the gall midges Rhopalomyia tanaceticola and Clinorrhyncha tanaceti

Efforts are under way, in cooperation with the Alberta Invasive Plants Council, Minnesota Department of Agriculture, and CABI Bioscience, to develop a biological control program for common tansy (Tanacetum vulgare). Click on Contact if you are interested in further information.
