Records of some hymenopterous parasitoids of serpentine leaf miner, Liriomyza trifolii in vegetable ecosystems in Kashmir.
A survey on the parasitoids of L. trifolii was carried out in several important vegetable-growing areas of Kashmir Valley (Anantnag, Baramulla, Budgam, Ganderbal and Srinagar) in Jammu and Kashmir, India, during 2005-06. Infested leaves of host crops such as Lagenaria siceraria, Luffa cylindrica, Cucurbita maxima, Cucumis sativus, C. melo, Lycopersicon esculentum [Solanum lycopersicum] and Solanum tuberosum were collected and brought to the laboratory. The survey revealed the occurrence of 9 hymenopterans parasitizing the maggots of L. trifolii, consisting of 6 species of Eulophidae (Asecodes sp., Chrysonotomyia sp., Closterocerus indica, Diglyphus sp., Hemiptarsenus varicornis and Quadrastichus sp.), 2 from Braconidae (Dacnusa sp. and Opius sp.) and one species from Pteromalidae (Herbertia indica). Although these parasitoids, except Dacnusa sp., have earlier been reported on L. trifolii from India, they are new records for Kashmir Valley.
