Abstract

Antifeedant and molt disruption effects of 0.3% azadirachtin ap­plied one per week for four weeks were evaluated for the mole cricket Gryllota!pa gryllotalpa, in laboratory tests. The highest concentration of formulated product (5 ml extract/50 ml distilled water/25g crushed corn seeds) resulted in 98% mortality. Crickets surviving treatment grew more slowly and tunneled less compared to their untreated counterparts.
