Description	The effects of tebufenozide, a nonsteroidal agonist of ecdysone, on egg development and reproduction in the anautogenic mosquito Culex quinquefasciatus Say (Culicidae, Diptera) are examined. The study population originates from Hyderabad, India. A dose-dependent toxicity is observed when varying concentrations (10 ěg L1 to 10 pg L1 ) of a flowable formulation of tebufenozide, known as Mimic 2F, are applied to first-instar larvae in water. The median lethal dose (LC50) against larvae is very low at 1.29 ng L1 H2O. Doses below the LC50 induce vitellogenesis in the females that subsequently emerge, and these females lay eggs autogenically (without blood feeding). By comparison, doses higher than the LC50 inhibit ovarian development. There is a gradual degeneration of the ovaries, and the females die approximately 20 days after imaginal ecdysis without commencing vitellogenesis. The results are discussed in relation to the endocrine and nutritional regulation of vitellogenesis in C. quinquefasciatus, and the possibility of using tebufenozide to regulate populations of some species of mosquito.
