Abstract
Bactrocera oleae (Gmelin) (Diptera: Tephritidae) is the key pest on olives in the Mediterranean area, representing 97% of world production. Olive fly larvae feed on olive fruits, bringing about premature drop of attacked fruits and direct pulp destruction as well as increasing oil acidity, which render the oil unmarketable. Management of this pest largely depends on chemical control, based essentially on adulticide treatments using protein baits, consisting of the spraying on the foliage of droplets containing an attractant (protein hydrolysates) and a toxic dose of insecticide (commonly, an organophosphate). Among the insecticides that are registered or have potential activity to be used on olive groves against the olive fly are fipronil, imidacloprid, natural pyrethrins+piperonyl butoxide and spinosad. Currently, dimethoate is the most used. One of the problems of the pesticide use in the olive orchards is the negative impact on the auxiliary insect fauna, being the predatory larvae of C. carnea the major oophagous predators of the olive moth, Prays oleae (Bernard), the second pests on importance on Mediterranean basin. Within this framework, the maximum recommended dose of those insecticides were tested on C. carnea following the IOBC (International Organization of Biological Control) guidelines for extended laboratory and persistence tests. Fipronil was the most toxic insecticide, following, from higher to lower toxicity, of dimethoate, imidacloprid, natural pyrethrins+piperonyl butoxide and spinosad.
