Technical Abstract: Insects can promote mycotoxin formation in commodities such as corn, peanuts, cotton, treenuts and some fruits by carrying inoculum and creating openings that allow the fungi to enter. Many different types of insects, as well as mites, may be involved. Caterpillars, weevils, and sap beetles are the most common insects that promote establishment of mycotoxigenic fungi in several different commodities. However, because other factors also influence fungal infection and mycotoxin production, the effectiveness of insect control in indirectly preventing high levels of mycotoxins can vary. There are several examples where insect control has substantially reduced the levels of mycotoxigenic fungi and mycotoxins in different commodities. Present commercially available formulations of insecticides can be effective, but often are not economical. Plant resistance promises to be a cost effective measure, but no resistance trait that covers all potential vectors for a particular crop presently is available in commercial material. Integrated management programs that include insect control hold the most promise for success, but are presently only being implemented on a limited basis.
