Organophosphorus insecticides on non-target species in Manipur: A study on toxicity


RK Memsana Devi

Biology studies contributes to the knowledge regarding lethal concentrations and safe concentration of a particular pesticide and helps in its application in agriculture and piscicultural operations in such quantities which do not cause mortality of the non-target organisms. This paper attempts to study complete picture regarding pesticides pollution in the lakes and their effect on non-target organisms, the findings may be used in formulating a policy towards rational used of pesticides in the area with a view to minimize its harmful after effects. The time at which the pesticides are added into the water will be noted along with the room and water temperatures. The findings of the present investigation are in agreement with the work of Jha and Singh (1984). The in descending order against adult Tribolium castaneum was Quinalphos (0.004197 ppm) > dimethoate (0.006500 ppm) > (0.008622 ppm) and monocrotophos (0.019440 ppm) as LC50. Thus in their study dimethoate is far more toxicity than malathion but in my present study it is found that malathion is far more toxicity than that of dimethoate.
