ABSTRACT
JOURNAL OF PLANT PROTECTION RESEARCH Vol. 52, No. 3 (2012) *Corresponding address: msco1381@gmail.com CHANGE IN LIFE EXPECTANCY AND STABLE AGE DISTRIBUTION OF THE DIAMONDBACK MOTH, PLUTELLA XYLOSTELLA (L.)

Decreased concentrations are necessary. Insecticides have lethal and sublethal effects. The aim of the present study was to determine the behavior of Plutella xylo- stella when exposed to sublethal doses of indoxacarb in terms of the age-specific fecundity (m x ), life expectancy (e x ) and stable age distribution (C x ). Also, the effects of sublethals on the pre-oviposition, oviposition and post-oviposition period of this insect were investigated. The results show that exposure to this insecticide decreased the age-specific fecundity (m x ) and life expectancy (e x ) of the insect. Although the pre-oviposition period was delayed in the treated groups, the post-oviposition period significantly decreased when exposed to LC 10 and LC 25 doses (the dose concentrations killed 10 and 25% of the populations) of indoxacarb. The oviposition period did not change. Furthermore, sublethal concentrations of the applied insecticide caused changes in the exposed structure.
