Abstract
Laboratory expts. showed that certain "inert" materials, when applied as dusts, kill adult bean weevils. Of the 6 "inert" materials tested, bentonite was most effective, and MgCO3 crystalline silica, amorphous silica, talc and walnut shell flour were less effective in the order named. Higher insecti-cidal efficiency was obtained with finer particles. The "inert" material did not affect the O2 consumption of the insect. It seemed to have killed the insects by desiccation.This publication has 1 reference indexed in Scilit:
