Diversity of parasitic fauna in mango ecosystem, PAJANCOA and RI, Karaikal, U.T. of Puducherry

Abstract

The present investigation was carried out to study the parasitic fauna in rice ecosystem during Kharif 2017 and Rabi 2017-18 at Pandit Jawaharlal Nehru College of Agriculture and Research Institute (PAJANCOA and RI), Karaikal, U. T. of Puducherry. A total of 3414 parasitoids were collected in mango ecosystem during Kharif 2017and Rabi 2017-18 represented eight superfamilies namely Chalcidoidea (2061), Platygastroidea (407), Ichneumonoidea (465), Chrysidoidea (33), Cynipoidea (62), Evanoidea (7), Diaprioidea (280) and Ceraphronoidea (99). In mango ecosystem there were twenty two families during Kharif 2017and Rabi 2017-18 representing Chalcididae (60), Aphelinidae (73), Mymaridae (307), Encyrtidae (153), Trichogrammtidae (31), Eulophidae (27), Eurytomidae (52), Eupelmidae (1167), Torymidae (1), Pteromalidae (131), Agonidae (3), Elasmidae (14), Tetracampidae (42), Platygastridae (407), Ichneumonidae (152), Braconidae (313), Bethylidae (27), Dryinidae (6), Cynipidae (62), Evaniidae (7), Diapriidae (280) and Ceraphronidae (99). It was found that all the families of parasitic fauna showed different level of correlations with maximum and minimum temperature and relative humidity.
