The sciand fly, [Lyconella mali (Fitch)] , is the most significant insect pest of commercial mushrooms m Ontario, Canada and in Pennsylvania, USA. The larvae will feed on Phase II compost, spawn grains, mycelia, primordia, and carpophores. The adult insects are vectors of mushroom pathogens: Verticillium, Mycogone, Dactylium. The eminent presence of the insects at cool-down and during spawning set the stage for at least two generations of adults in the mushroom growing facility within a ten week cropping cycle. The ferocious appetite of the larvae and the ability of the insect to reproduce several generations withm a crop cycle make this insect very devastating to mushroom cultivation.

Pest management practices have assisted in reducing the pest problem (Wuest and Bengtson, 1982). Insecticide usage is one component of the pest management strategies. Testing potential insecticides under commercial mushroom-like growing conditions is an essential element for vendor sales, extension recommendations, and for the actual registration of the materials. The information discussed in this paper was generated to meet the needs of vendors, extension personnel, and government registration processes.
