ABSTRACT
During the 2000/2001 season, the polyphagous leafroller Argyrotaenia sphaleropa (Meyrick) caused damage in commercial peach orchards, in Rio Grande do Sul, Brazil. Caterpillars scrape the fruit epidermis, mainly at the insertion of the stalk or in the junction of the leaves and fruits, depreciating them commercially. Despite conventional chemical treatments, losses were around 2%; however, many growers have mistaken the A. sphaleropa damage as caused by Grapholita molesta(Busck), and have used insecticides to control the last one.
RESUMO
Durante a safra de 2000/2001 foi observado o ataque de Argyrotaenia sphaleropa (Meyrick) em pomares comerciais de pessegueiro na Serra Gaúcha, RS. As lagartas raspam a epiderme dos frutos, principalmente na região de inserção do pedúnculo ou em locais de contato entre folhas e frutos,depreciando-os comercialmente. As perdas na colheita, mesmo com controle químico, foram de aproximadamente 2%; porém, muitos produtores têm confundido o dano de A. sphaleropa comGrapholita molesta (Busck), empregando inseticidas de forma errônea para o controle da última.
