Ooencyrtus pityocampae Mercet rearing on three substitute hosts in laboratory to implement a biocontrol of Thaumetopoea pityocampa Den. & Schiff.

Abstract

Egg parasitoids are considered as efficient biological control agents and are used worldwide for control of several pests in many crops. Ooencyrtus pityocampae Mercet (Hymenoptera: Encyrtidae) is a polyphagous egg parasitoid which parasitises Thaumetopoea pityocampa Denis & Schiffermüller (Lepidoptera: Notodontidae) eggs. To implement a biocontrol of pine processionary moth with these parasitoids, it is first necessary to rear O. pityocampae. Because of allergy risks and problems of long life cycle and behavior, Thaumetopoea pityocampa is not easy to rear so the use of substitute host is unavoidable. In this project, Philosamia ricini Danovan (Lepidoptera: Saturniidae), Halyomorpha halys Stål (Hemiptera: Pentatomidae) and Nezara viridula L. (Hemiptera: Pentatomidae) were evaluated all three as substitute hosts. Different biological characteristics of O. pityocampae were determined for each one at 25 ± 1°C, 65 ± 5% RH, and a photoperiod of 16:8 h (L: D): development time, emergence rate, longevity, parasitism rate and fecundity. Results show that all three can be used to rear O. pityocampae.
