Toxicity of commercial fungicides to larvae of Drosophila melanogaster Meigen (Diptera, Drosophilidae) and effect on the sex ratio

Marchal Segault, D.

The effects of Bouillie bordelaise (copper sulfate) at 50-250 p.p.m., Benlate (benomyl) at 50-250 p.p.m., Euparene (dichlofluanid) at 250-1250 p.p.m. and Dithane M-45 (mancozeb) at 250-1250 p.p.m. incorporated into artifical diet on Drosophila melanogaster were investigated. The fungicides had no effect on the eggs, but post-hatching mortality was observed to increase with increasing dose.
