Hypoglycemia in malathion-treated chick embryos.

Chick embryos were exposed to a teratogenic dose of Malathion at the 5-day incubation stage, and the effect of this treatment on blood sugar levels was studied from the 9th day of incubation to hatching. The Malathion caused a decrease in blood sugars and this hypoglycemia persisted throughout the incubation period until day 19.
