Abstract
When the IGR, Thompson-Hayward 6040 (N (4-chlorophenyl)-N′ (2,6-difluorobenzoyl) urea) was fed to adult ♀ Anthonomus garndis Boheman for 24 h, the concentration of the chemical required to inhibit the hatch (embryonic ED50) of 50% of the eggs resulting at ca. 72 h after ingestion was 431 ppm. It was 2797 ppm at ca. 216 h. The EI60’s (intervals required for inhibition to decrease to 50%) were 32 h for an initaial dose of 201 ppm, 62 h for 576 ppm, and 218 h for 4034 ppm. The ED60 of TH 6040 for an oral dose of 0.11 μg was 84 hours.This publication has 0 references indexed in Scilit:
