Abstract:

An experimental preparation of Bacillus thuringiensis Berliner var. israelensis (Goldberg) tested against a sciarid fly Lycoriella mali (Fitch) in mushroom compost gave over 90% control. The LC95 was one part B. thuringiensis var. israelensis to 696 parts water (wt/wt); the L95 was one part B. thuringiensisvar. israelensis to 64 parts water. With a 1:60 dilution, the mortality exceeded 99.5%. Two commercial preparations containing B. thuringiensis var. israelensis tested at a dilution of 1:100 produced mortality rates of either 79.2 or 94.4%.
