Studies on the toxicity of some carbamate fungicides in drosophila melanogaster insecta diptera


, : Studies on the toxicity of some carbamate fungicides in drosophila melanogaster insecta diptera. Environmental Research 37(1): 26-32

This paper reports the effects of 3 commercial powders mixed into the diet, Dithane M-45 (mancozeb 80%), Pomarsol (thiram 80%) and Peltar (maneb 50% and methylthiophanate 25%), on survivorship of adults Drosophila and on the progeny. With wild-type adults (Oregon), fungicides were added to the diet at the rate recommended on the label. The mean lifespan was reduced by 42.5% (Pomarsol), 50% (Dithane M-45) and 83% (Peltar). For larvae of 2 strains (Oregon and triploid) intoxicated with Dithane M-45 and Peltar, a linear relationship was demonstrated between the doses and the percentage of the progeny reduction. The calculated doses inducing a 50% reduced progeny (PR50) are in the range of 400 to 700 ppm. With Pomarsol in the range of 500 to 1500 ppm and for the both strains, the progeny was decreased by .apprx. 60%. A very reduced size and a leg paralysis were observed with each toxic powder for Oregon and triploid flies. A triploid stock of chromosomes evidently does not significantly modify the reaction of the flies.

We isolated a new mouse gene that is highly expressed in thymocytes, testis, and brain. This gene, SRG3, showed a significant sequence homology to SWI3, a yeast transcriptional activator, and its human homolog BAF155. SRG3 encodes 1,100 amino acid...
