Notes
Quantification of sublethal toxicity of malathion in different agricultural doses has been studied on a dominant rice field earthworm Drawida willsi, Michaelsen, on the basis of population biology, secondary production and energy utilization strategies. Sublethal stress effects of zero, 2.2 µg g-1 (single agricultural dose) and 8.8 µg g-1 (tetra agricultural dose) malathion have been compared and their impacts on population biology, bioproductivity, metabolism and ecoenergetics had been discussed. Use of higher agricultural dose (>2.2 µg g-1) and public health dose (17.6 µg g-1) might severely affect earthworm population and activity.
