Abstract

The effect of treatment with juvenile hormone and five of its analogs on embryonic development of the spruce budworm was studied. All compounds were applied topically in acetone solution to budworm egg masses, and all were found to have ovicidal activity. Most active was the dichloro analog, which required a minimum dosage of 50 μg per egg mass to ensure embryonic death in all the treated eggs. A similar result was found for juvenile hormone, while juvabione, ethyl-aromatic terpenoid ether, and farnesyl methyl ether required a dosage of 100 μg per egg mass to achieve this result. At this latter dosage level, 6% of the eggs treated with methyl aromatic terpenoid ether hatched.
