Investigations on the effects of juvenile hormone analogue methoprene to cotton leafworm [<em>Spodoptera littoralis</em> Boisd. (Lep.:Noctuidae)] :II. Effects on last instar larvae.

Abstract

The experiments were carried out under the controlled laboratory conditions of 24±2 °C temperature, %60±5 RH and 14:10 h photoperiod in Ankara University, Agricultural Faculty, Plant Protection Department between 1991-1993.Juvenile hormone analogue methoprene was tested on last instar larvae of Spodoptera littoralis which is the pest of cotton and vegetables in Turkey. Treatments were as topical application, pulverization and feeding to newly moulted last instar larvae. Finally, the larval duration and weights increased and superlarval, ekstralarval instars and larvae-pupa intermediates occurred with the certain dosages of methoprene.
