Determination of selected biological characteristics of pistachio seed chalcid ( megastigmus pistaciae Walker) (Hym.: Torymidae) for its managements in Southeast Turkey.

摘要

The project was conducted in pistachio orchards in Gaziantep and Sanlurfa in 2007-2009. The purpose of the study was to determine biological characteristics of pistachio seed chalcid (Megastigmus pistaciae Walker) that can be useful in its control. Fruits infested with the pest were placed in cages in January in orchards in both cities. The cages were checked weekly starting in the first week of April. After the first adult emergence in the orchard in Gaziantep, daily monitoring was initiated while the orchard in Sanlurfa continued to be checked weekly. First and maximum adult emergence times and adult emergence period were determined in both orchards. In the orchard in Gaziantep, in July in 2008 and 2009, the pest pupates within fruits and have left the fruit as an adult. During the study, pupa period, adult lifespan, male/female ratio and host range of the pest in Southeastern Turkey were determined.
