Abstract

Diversity of Chalcidoids from Hilly tract of Tamil Nadu was investigated at Kolli hills of Namakkal district during 2014-2015. An attempt was made to survey possible parasitic fauna of Kolli Hills with more emphasis on Chalcidoidea of parasitic Hymenoptera in various agro ecosystems. On the total of 6792 parasitic Hymenoptera were collected, out of which 2755 were Chalcidoidea super families. Out of chalcidoids 1358 belonged to Mymaridaefamily, 391 to Encyrtidae, 374 to Eulophidae, 365 to Chalcididae, 179 to Trichogrammatidae, 59 to Aphelinidae, 23 to Euritomidae, four to Eupelmidae, one each to Torimidae and Agaonidae. Within the ecosystem only Mymarid could be recovered and it’s represented by 20 genera. The status of Mymarid is compared with world and Indian fauna and their biocontrol potential discussed.

Keywords

Parasitic hymenoptera, genera, ecosystem, Mymaridae.

Conclusion

Since such a rich biodiversity of beneficial parasitc hymenoptera especially in mymarids available in nature, now it is upto the agricultural experts and farmers to suitably modify their plant protection schedule, so that their biocontrol potential fully exploited. They can live in advanced trophic level and this ia an important factor in maintain a suitable and stronger homeostasis in the ecosystem.
