Possible Residual Effect of Pesticide onBactrocera oleaeRossı (Dıptera:Tephrıtıdae) Adults

The olive fruit fly, Bactrocera oleae Rossi, is the main pest of olive orchards in the Mediter ranean Basin (Economopoulos 2002). The larvae are monophagous (Weens & Nation 2003) and compelete their development in the mesocarp of the olive fruit. Females oviposit eggs inside the fruit and decreasing the value of table fruit. Olive fruit fly larvae cause important damage to table olives, and damage oil production by increasing acidity of olive oil. Small scale rearing on artifi cial diets was reviewed by Silva (1970), Hagen (1966), Hagen et al. (1963), Mittler & Tsitsipis (1973) and Gene (2008), and on host olive fruits by Tzanakakis (1971) and Gene & Nation (2008). Olive flies reared on an artificial diet differ from
