Abstract

Indoxacarb is a recently presented oxadiazine insecticide with activity against an extensive range of pests, including house flies. The efficacy of Avaunt (Indoxacarb 15% EC) on newly ecdysed 2nd and 3rd instar Musca domestica L. larvae was evaluated. Chemical concentrations tested fluctuated from 20 to 100 ppm of indoxacarb, that indoxacarb Observations revealed caused quick mortality at doses >50 ppm. At concentrations below 50 ppm, it acquired longer for indoxacarb to cause 100% mortality. In the food treated 100% mortality for the 2nd and 3rd instar larvae caused within 48 to 144 hrs. and 72 to 144 hrs. respectively, as well as in spray treated caused within 48 to 144 hrs. and 96 to 144 hrs. respectively. Indicated that ingesting indoxacarb was highly toxic to the second and third instars of M. domestica. The LC590 values of indoxacarb exceeded the highest concentrations tested 100 ppm. LC50 for 2nd and 3rd larvae exposed to food treated were 19.18, 10.78 and 10.08 and 14.281, 12.40 and 9.876 ppm at 24, 48 and 72 hrs respectively. LC50 for 2nd and 3rd larvae exposed to spray treated were 23.54, 14.73 and 9.52 and 23.564, 9.330 and 7.912 at 24, 48 and 72 hrs. Results of the conducted bioassay showed that 2nd instars were more vulnerable than the 3rd instars as the LC50 and LC90 values.
