Winfred Aol Opiyo, an Entomologist at National Agricultural Research Organization –NARO told URN in an interview that the scientific investigation will determine the correct dose of chemicals being used depending on the life stage of the insects, the reproductive potential of the insects in relation to what they feed on and among other things.
Arnold Waiswa Ayazika, the NEMA director, Environmental Monitoring and Compliance says beyond the suppressing of the locusts, NEMA is interested in monitoring the potential impact of chemicals on water sources, food crops and or any other non-target organisms.
Government has listed three chemicals to use in the spray against the desert locusts. They include Fenitrothion 96 per cent low volume formulation, which is a phosphorothioate insecticide. Others are Malathion which is an organophosphate insecticide. This is commonly used to control mosquitoes and a variety of insects that attack fruits, vegetables, landscaping plants, and shrubs as well as Pyrethroid insecticides.
