Protecção integrada da oliveira contra a cochonilha negra, Saissetia oleae (Oliv.)

Abstract

A cochonilha negra da oliveira, Saissetia oleae (Oliv.), e uma espécie de extensa distribuição geográfica, que se inclui entre as principais pragas da oliveira, na generalidade das regiões oleícolas, entre as quais a região transmontana. No presente trabalho procede-se a uma compilação de informação considerada penitente na perspectiva da protecção integrada da cultura contra o fitófago, com particular ênfase para os conhecimentos disponíveis relativamente a Trás-os-Montes. Nesta óptica, depois de uma breve referência à biologia do insecto , analisam-se os princípios e componentes da protecção integrada, focando-se os factores de limitação natural, a utilização dos níveis económicos de ataque e fundamentação das tomadas de decisão fitossanitária e a escolha dos meios de protecção. A concluir discute-se a necessidade de dispor de métodos simples e rápidos para poderem ser aplicados na estimativa do risco e de não usar níveis económicos de ataque demasiado restritivos para a praga.
