Effects of a commercial 2,4,5‐T butoxyethyl ester product on oogenesis and fertility of a Drosophila melanogaster (Canton‐S) strain were measured, as well as the toxicity to adult flies. A concentration of 250 ppm, 2,4,5‐T in the food reduced fertility with about 50 %. Females given only 1 ppm still showed significant disturbances in their egg follicle development. The LD 50 value (dose required to produce 50 % mortality) for adult female flies had a higher magnitude of about 4700 ppm. Fully developed oocytes showed chromosomal abnormalities which were ascribed to treatment with the 2, 4, 5‐T product, also in low concentrations (down to 1 ppm).
