th th Abstract: Snails Lymnaea accuminata, were exposed to 1.4 mg/l (1/10 of 96 hrLC50) and 2.8 mg/l(1/5 of 96hr LC50) of insecticide Dichlorvos. Initially at 24 hours, at both the concentrations Increase in respiratory rate is noted. At 48 hours stage, increase in respiratory rate is noticed at both the sublethal concentrations. At 72 hours stage in both the sublethal concentrations reduction in oxygen consumption is noted. At the end of 96 hours, again in both the concentration decrease in oxygen consumption prevailed. These experimental snails upon transfer to fresh water for 24 hours, showed recovery in respiratory rate. Respiratory rates are discussed with respect to sublethal concentration and time of exposure to toxicant Dichlorvos.

Spray dried liposomes had mean size of 3-4 μ and FPF of 9-10%. Inclusion of antistatic agents such as leucine and magnesium stearate did not improve the aerosolisation behaviour of DPIs in this study. Further studies are warrante...
