Beneficial Bug Cards

The University of Wisconsin Integrated Pest Management Program has produced two full color cards depicting various natural enemies of cole crop insect pests "Good Guys in the Insect World". These 4-1/4 x 6-1/2" cards feature four photographs of natural enemies on each side with accompanying explanatory text.

One card (above) highlights common parasites: the wasps Cotesia glomerata and Pteromalus puparum, and the fly Voria ruralis that attack imported cabbageworm; the wasp Diadegma insulare that parasitizes diamondback moth larvae, and wasps that parasitize aphids and produce aphid mummies.

The other card (above) focuses on the predators and diseases of cabbage pests: lady beetles, ground beetles, lacewings, syrphid fly larvae, cabbage looper virus and Bacillus thuringiensis.

Small quantities of the cards are available from the MBCN Editor.
