Laboratory evaluation of 2-[1-methyl-2-(4-phenoxyphenoxy) ethoxy] pyridine against larvae of mosquitoes and housefly

Abstract

A newly synthesized juvenile hormone active compound, S-31183 (2-[1-methyl-2-(4-phenoxyphenoxy) ethoxy] pyridine) was evaluated for its inhibition of emergence of adult Culex pipiens pallens, Anopheles stephensi, Aedes aegypti and Musca domestica in the laboratory. It was more active than methoprene, diflubenzuron, or temephos against last instar larvae of Cx. p. pallens, An. stephensi and Ae. aegypti. S-31183 was more active than methoprene and diflubenzuron against 4-day-old larvae of M. domestica in the artificial medium, and more active than methoprene against eggs and 4-day-old larvae of M. domestica in the chicken manure medium.
