LC50 of lambda-cyhalothrin stimulates reproduction on the moth Mythimna separata (Walker)
Pesticide Biochemistry and Physiology, 2019Lambda-cyhalothrin has long been recommended as an effective insecticide to control the oriental armyworm, Mythimna separata (Walker), a notorious migratory pest of agricultural plants. Previous researches have suggested that survival, development, and reproduction of insects are influenced by sublethal concentrations of insecticides.

Acute Toxicity and LC50 Values of Chlorpyrifos on Eudrilus eugeniae
BIOINFOLET - A Quarterly Journal of Life SciencesPresent study evaluates acute toxic effects of chlorpyrifos on earthworm ( Eudrilus eugeniae ) under laboratory conditions. Acute toxicity bioassays was performed following OECD ( 1984) guideline 207 using artificial soil. The LC50 values were determined after 7 and 14 days of exposure.

Standard error of lc50 and sample size in fish bioassays
Water Research, 1972Abstract The relationship between the relative error and sample size in fish bioassays was investigated empirically and theoretically. It was shown that if the mean concentration tested is near the estimated lc 50 and the same sample size is used at each test level, the dependence of relative error on sample size is predictable.

LC50 Value of Paraquat (24%) in Drosophila Melanogaster Larvae
BIOINFOLET - A Quarterly Journal of Life SciencesThe objective of present investigation was to determine the Lethal Concentration 50 (LC50) of commercially available paraquat. a herbicide, at 24 % dilution with second instar larvae of Drosophila melanogaster. For this purpose the second instar larvae, were exposed to different concentrations of paraquat (20, 22, 24, 26 and 28 µl/ml).

Acute LC50 Value of Methotrexate in Drosophila Melanogaster Larvae
BIOINFOLET - A Quarterly Journal of Life SciencesThe value of LC50 of the commercially available immunosuppressive drug methotrexate (MTX) was determined using the larvae of Drosophila melanogaster. For this purpose, third instar larvae were exposed to different concentrations of MTX (75, 100, 150, 200 and 250 ppm). Probit analysis was done on the dose-response data in order to find LC50. The results

Acute toxicity and LC50 determination of roundup on Eudrilus eugeniae
BIOINFOLET - A Quarterly Journal of Life SciencesPresent study was undertaken to assess effect of Roundup on earthworm, Eudrilus eugeniae. The values for LC50 were determined over 7 and 14 day exposure periods. Earthworms were exposed to concentrations ranging from 0.01 to 1000 ppm in artificial soil.
