The influence of grain moisture content on the efficacy of silica dust on Prostephnus truncatus (horn) (Coleoptera: bostrichidae) and Sitophilus zeamais (motsch) (Coleoptera: curculionidae)

The effect of grain moisture content on toxicity of silica dust against adult populations ofProstephanus truncatus and Sitophilus zeamais was investigated at 8.6, 13.7, 14.1, 15.4 and 17% moisture content levels of maize grains. Concentration levels of 0.25 to 50 mg/50 g maize grains were tested against P. truncatus and 0.25 to 7 mg/50 g maize grains for S. zeamais. The LC50 of the...

Non destructive method to manage the most dreaded pest Callosobruchus maculatus (Fab.) in Black gram Vigna mungo L.

Under storage conditions, pulses suffer maximum grain loss due to the dreaded stored grain bruchid pests. Effect of different grain protectants on oviposition of pulse beetle, Callosobruchus maculatus showed that untreated check (13.31) registered the maximum number of eggs followed by seed treated with coarse river sand (11.62). Minimum number of eggs was recordedin activated clay...
