Three methylenedioxyphenoxy-terpenoid ethers with high morphogenetic activity on a variety of insects prevented egg hatch when they were applied to eggs of the Mexican bean beetle, Epilachna varivestis Mulsant, and the cigarette beetle, Lasioderma serricome (F.). Eggs of E. varivestis were very sensitive to these synthetic hormones during the first half of the egg stage. Hatch was reduced by 98% when 1-day-old E. varivestis eggs were exposed to the vapors from 1 µg of the most potent hormone in a 2X9-cm petri dish or dipped for 5 seconds in a solution of 10 ppm. The relative potency of the hormones as fumigants differed for the 2 species. The most active compound was as potent a fumigant as parathion on E. varivestis eggs. Young eggs of the omnivorous leaf roller, Platynota stultana Walsingham; the greenhouse whitefly, Trialeurodes vaporariorum (Westwood); the tobacco hornworm, Manduca sexta (Johannson); and the large milkweed bug, Oncopeltus fasciatus (Dallas), were insensitive to relatively high concentrations of the 3 compounds.
