S. Rani et al., COMPARATIVE TOXICITY OF DIFFERENT FORMULATIONS OF CYPERMETHRIN, DELTAMETHRIN AND PERMETHRIN AGAINST DROSOPHILA-MELANOGASTER (KU STRAIN), Journal of environmental biology, 18(4), 1997, pp. 343-349
Different formulations of deltamethrin, cypermethrin and permethrin we
re mixed in the culture medium to determine their toxicity against Dro
sophila melanogaster. The LC50 values of these pyrethroid compounds af
ter 24 hours of treatment, were found to be 0.36, 4, 13, 16 and 51 ppm
for cypermethrin, Cooper (permethrin + PBO), permethrin without PBO (
permethrin alone), deltamethrin and the BHC formulation, respectively.
