Population Dynamics and Damages on Shoots and Fruits Caused by of Grapholita molesta Busck (Lep.: Tortricidae), Anarsia lineatella Zell (Lep.: Gelechiidae) and Ceratitis capitata (Wied.) (Dip.: Tephritidae) in Some Peach Varieties

The study was conducted to determine population dynamics and damages on shoots and fruits caused by Anarsia lineatella Zell, Grapholita molesta Busck and Ceratitis capitata (Wied.) by using sex pheromone at six peach varieties including Early Red, June Gold, Redhaven, Monreo, Springcrest and Dixired at Research Center of Ministry of Agriculture in 2002 and 2003 in Sultanhisar district, Aydin, Turkey. A. lineatella and G. molesta were the major pests of peach orchards. However, C. capitata was not a problem. Both lepidopteran pests were firstly observed at the last week of March in 2002 and first week of May in 2003 and continued by the first week of November and had four peaks during the two years. They mainly damaged on the shoots and rarely on the fruits at all varieties. The highest damage on the fruits was occurred in late ripining varieties including Monrea and Dixired whereas the lowest damage on the shoots was in the same varieties and it was statistically different from the other peach varieties. The largest infestation on shoots was observed on east side in 2002 and south and east in 2003. The study showed that the use of sex pheromones for A. lineatella and G. molesta will help the growers to reduce chemical applications, to save management costs and to natural enemies and thus, be useful in IPM.
