The use of the Insect Growth Regulators fenoxycarb and epofenonane against leafrollers in Integrated Pest Management in apple orchards
article
The applicability of the Insect Growth Regulators (IGR) with juvenile-hormone activity, epofenonane and fenoxycarb, was investigated in an Integrated Pest Management (IPM) program in six apple orchards during 1977-1983, against tortricid larvae. In some of these orchards Adoxophyes orana (F.v.R.) was the main pest species, and in others Pandemis heparana (Denn. & Schiff), Archips podana (Scop.) and Archips rosana (L.) were predominant. The IGR was sprayed twice at the time of emergence of last-instar larvae in spring, and resulted in adequate reduction of the numbers of the leafroller complex during the rest of the year. Reinfestation by moths never resulted in an increase to a harmful population level. IGR treatments kept fruit damage by leafrollers at a low level. ?? 1985 Dr W. Junk Publishers.
