A MODEL OF ETHANOL TRAP TO COLLECT SCOLYTIDAE AND PLATYPODIDAE (INSECTA, COLEOPTERA)

Abstract

Aluno do CPG em Entomologia ESALQ-USP, Depto. de Entomologia 13400 - Piracicaba - SP The integrated pest management is the complex of measures which has been shown to be the efficient approach on pest control. And the key piece in pest management is a suitable monitoring. The ambrosia beetles of the families Platypodidae and Scolytidae are amongst the economic pests of the Order Coleoptera. The colonization of new trees by these insects is closely related to a bouquet of volatile components released by the plants. These pheromones may be divided into those exerting long distance attraction and the ones of landing and beginning of wood boring, and from the components of more localized action, the ethanol is the most known. Buchanun (1941) and Browne (1952), cited by CAGNE & KEARBY (1978), have already referred to the attraction of ambrosia beetles by the ethanol. SAMANIEGO & GARA (1970) have shown the efficacy of ethanol in attracting ambrosia beetles, and that this action was directly proportional to the concentration used. VITE (1980) has observed the importance of ethanol .in the landing and beginning of boring of
