Abstract:
The studies showed that all larvae,regardless of their incubating time earlier or later,make no damage before the cotyledons of Fistacia chinensis Bunge fruits begin to grow.But they remain alive and at younger instars.Once the cotyledon starts to grow,larvae bore embryoes and make damage.The period between the end of oviposition and the beginning of cotyledon growth about(20-30 days)provides an opportunity for controlling Eurytoma plotnikovi Nikolskaya and is the critical time for chemical control.Spraying agrochcmicals at Ulra-Low-Volume(ULV)or common volume have been used in the control:The effectiveness of the control with monocrotophos was 70.88-88.0 %.with the highest of 97.8 %.
