| Abstract: | The diamondback moth, Plutella xylostella (L.) is a major pest of crucifers in Iran. In this study, the influence of two sublethal concentrations (LC10 and LC25) of an insect growth regulator, hexaflumuron on life expectancy (e x ), stable age distribution (C x ), age-specific fertility (m x ) and number of fertile eggs per day was investigated. Results showed that the sublethal doses of hexaflumuron decreased life expectancy (e x ), age-specific fertility (m x ) and number of fertile eggs per day of P. xylostella. Also stable age distribution (C x ) of population in next generation was changed and rate of adults in sublethals was increased compared to control. According obtained results, hexaflumuron is a good choice for IPM strategy in controlling the diamondback moth. |
