Adult longevity of certain mosquito species after larval and pupal exposure to sublethal concentration of an insect growth regulator, hexaflumuron.
Longevity of the adults of three vector species, Culex quinquefasciatus, Anopheles stephensi, and Aedes aegypti was drastically reduced when they were exposed at larval and pupal stages to sublethal concentrations of an insect growth regulator hexaflumuron. When the three species were exposed to 0.05 mg/l at the pupal stage, males and females of Cx. quinquefasciatus suffered a more shortened life span than other species. Among the females whose feeding activity was adversely affected by IGR treatment at the pupal stage, Ae. aegypti showed the minimum survival duration with LT50 of 2.74 days.
