Effect of Temperature and Retention Period on the activity of Olive Leaf Midge Dasineura oleae F. loew (Dipter: Cecidomyiidae) and its Endoparasitiod

This work aimed to study the environmental factors influencing growth stopped of olive leaf midge Dasineura oleae F. loew (Dipter: Cecidomyiidae) and its host (Hymenoptera: Platygasteridae) Platygaster demades Walker, such as temperature and reservation period. A series of experiments had been done to end this phenomena of larvae by changing temperatures from suitable temperature at 20±1 °C accompanied with different photoperiods 16 L: 8D and relative humidity of 75± 5% during 15, 30, and 60 days, to low temperature at 7± 1 °C accompanied with complete darkness and relative humidity of 75± 5% for 15 days. This had been done after 30, 60, 90 and 120 days of growth stopped.
