Why identify stored insect grain pests?

0

Most insect control methods for stored grain work against all species. So you don´t need to identify the storage pests to make decisions about most control methods. But if you intend spraying grain with insecticides you may need to know which species are present if: • a previous application has failed and you want to know whether resistance was the reason – if more than one species survived, resistance is unlikely to be the cause • you intend using a residual protectant to treat infested grain – pyrimiphos-methyl, fenitrothion and chlorpyrifos-methyl are ineffective against lesser grain borer, and pyrimiphos-methyl and fenitrothion are generally ineffective against sawtoothed grain beetle • you intend using dichlorvos to treat infested grain – if lesser grain borer is present you need to apply the higher dose rate. This then increases the withholding period before grain can be marketed from 7days to 28days. Insecticide sprays are not registered for oilseeds and pulses, so identificatio
