Effect of the chemosterilant bisazir on the eggs of Earias fabia stoll.

Bisazir-induced inhibition of nucleic acids and protein, and enhancement of free amino acids in the eggs of treated Earias fabia (Lepidoptera; Noctuidae) is reported. The degree of alterations in various crosses followed: T male X T female greater than UT male X T female greater than T male X UT female, which was also reflected in the weight loss of eggs. The alterations have been attributed to the abnormalities in the developing embryos due to genic imbalance in the spermatozoa, nurse cells and oocytes, ultimately leading to embryonic death.
