Eficiência e período de arividade dos inimigos naturais de <i>Oncideres impluviata</i> (Fermar, 1824)(Col.: Cerambycidae).

Abstract

Objetivou-se, com este estudo, o conhecimento do conjunto de inimigos naturais e a ação destes ao longo do desenvolvimento das larvas de Oncideres impluviata. No período de 1984/85, em Almirante Tamandaré – Paraná, coletou-se periodicamente galhos de bracatinga (Mimosa scabrella Benth.) cortados pelo serrador. As larvas coletadas a campo completaram o ciclo em laboratório em tubos de ensaio contendo serragem umedecida de bracatinga. Ao retirar-se as larvas dos galhos anotou-se o ponto em relação à base-ápice do galho, além da data de coleta e o instar em que se encontravam. Avaliou-se a eficiência dos inimigos naturais e o período de atividade destes. As observações efetuadas permitiram concluir que a eficiência dos inimigos naturais e o período de atividade destes. As observações efetuadas permitiram concluir que a ação predatória foi mais eficiente do que o parasitismo, sendo que esta tende a diminuir com o desenvolvimento larval, ao passo que a ação predatória aumenta concomitantemente no decorrer do desenvolvimento das larvas. O parasitóide mais freqüente foi Cenocoelius sp. (Hym.; Gracanidae) e entre os predadores destacam-se Cregyadifformis (Col.; Coleridae) e Lithrips sp. (Thys.; Phloeothripidae), entre outros.
