Bactrocera oleae. Fattori naturali di controllo

Abstract

Bactrocera oleae. Natural control factors. Natural control factors (parasitoids and climatic factors) influencing the olive fruit fly, Bactrocera oleae, are analysed comparing two different areas of cultivated and wild olives, Sicily and the Western Cape of South Africa. Bactrocera oleae has a similar level of parasitization in both areas, much higher in wild olives than in cultivated ones. Climatic conditions are much more important than climatic factors, influencing the growth of olive fruit fly populations, producing a higher level of infestation in more humid and rainy productive seasons.
