Abstract

Halys dentatus is a phytosuccivorous insect mainly infesting Azadirachta indica. Two egg parasitoids viz., Anastatus sp. (Hymenoptera: Eupelmidae) and Trissolcus sp. (Hymenoptera: Scelionidae) of this bug have been observed parasitizing eggs. A maximum of 100% parasitization OCCUlTed during January to March and December while minimum parasitization (22.7%) was recorded in April. Overall parasitization of eggs was found 62.5%. Phasia sp. (Diptera: Tachinidae), a parasitoid of adults as well as nymphs, were recorded parasitizing up to 12.5% in September. Hexamermis sp. (Nematoda: Mermithidae) was found parasitizing adults and nymphs up to the extent of 9.0% in rainy season (July to September). Among all the recorded parasitoids, the potential one are Trissolcus sp. and Phasia sp. which could be tried for the biological control of Halys dentatus.
