Abstract:
The effects of different concentrations of thioacetamide (TAA) viz 8 mg, 16 mg, 24 mg, 40 mg, 48 mg 56 mg 64 mg 80 mg and 96 mg have been described on the development of house fly, Musca domestica. The house fly eggs (350-400) were introduced into each of the control and drugged media and then allowed to develop in the laboratory under 3 temperature conditions, i.e. 23-30° C, 30-35°C and 36-38° C. Every 24 hours, different developmental stages were taken out and were processed for whole mount studies. Thioacetamide has been found to (i) reduce the hatchability of eggs into larvae, while at stronger doses larvae also fail to metamorphose into adult flies (ii) shorten the duration of various developmental stages. Generally at higher doses the larval period reduces from 6 days to 5 or 4 days, depending upon the dose and period of exposure, (iii) reduce the size of various developmental stages. The larvae get thinner and feebler at higher doses of thioacetamide. The effect of TAA, with relation to the temperature at which the development has been carried out, has been discussed.
