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.

Year 1998, Volume: 38 Issue: 1, - , 13.12.1998

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.

Juvenil hormon analogu methoprene'in Pamuk yaprak kurdu [<em>Spodoptera littoralis</em> Boisd. (Lep.:Noctuidae)]'na etkileri : II. Son dönem larvalara etkileri.

Year 1998, Volume: 38 Issue: 1, - , 13.12.1998

Abstract

Ankara Üniversitesi Ziraat Fakültesi Bitki Koruma Bölümünde 1991-1993 yılları arasında yapılan bu çalışmada juvenil hormon analoğu methoprene, pamuk yaprak kurdunun son dönem larvalarına uygulanmıştır. Topikal aplikasyon, püskürtme ve besinle verme şeklinde yapılan uygulamalar sonucunda bileşiğin; larva süresi ve larva ağırlığını arttırdığı, ekstra ve süper larvalar ile larva-pupa arası dönemlerin oluşumunu teşvik ettiği, en düşük dozlarda bile gelişimi engellediği belirlenmiştir.
