Résumé L'action des parasites deLymantria obfuscata Walker [Lymantriidae: Lepidoptera] a été étudiée au Cachemire au cours des années 1983 et 1984. Le seul parasite oophage élevé futAnastatus kashmirensis Mathur qui parasitait entre 4,49 et 11,92 p. 100 des œufs. Des 15 sites d'études 10475 larves de différents stades et des chrysalides furent récoltées et élevées au laboratoire.Exorista rossica [Tachinidae: Diptera] attaquiat jusqu'à 8.42 p. 100 des larves par rapport au taux de 0,89 p. 100 dû àCompsilura sp.Tetrastichus sp. [Eulophidae: Hymenoptera] était le parasite dominant parmi les six attaquant les chrysalides, avec un taux de parasitisme de 33,41 p. 100, suivi parPimpla sp. etTheronia atalantae atalantae [Ichneumonidae: Hymenoptera] qui parasitaient 6,84 et 4,03 p. 100 des chrysalides respectivement.Brachymeria intermedia Nees [Chalcididae: Hymenoptera] parasitai jusqu'à 2,98 p. 100, tandis queBrachymeria lasus signalé pour la lère fois au Cachemire ne parasitait pas plus de 2,01 p. 100 des individus, et n'était pas largement répandu dans la région.
Notes:
Abstract Incidence of parasites ofLymantria obfuscata Walker [Lymantriidae: Lepidoptera] was studied in Kashmir during 1983 and 1984. The only egg parasite reared wasAnastatus kashmirensis Mathur parasitising between 4.49 to 11.92 percent of eggs. From 15 study sites as many as 10475 larvae of different stages and pupae were collected and reared in laboratory.Exorista rossica [Tachinidae: Diptera] was recorded to parasitize upto 8.42 per cent of larvae compared to 0.89 percent byCompsilura sp.Tetrastichus sp. [Eulophidae: Hymenoptera] was observed to be most dominant of the 6 pupal parasites, accounting for 33.41 percent of the measured parasitism, followed byPimpla sp. [Ichneumonidae: Hymenoptera] andTheronia atalantae atalantae [Ichneumonidae: Hymenoptera] which parasitized 6.84 and 4.03 per cent of pupae respectively.Brachymeria intermedia Nees [Chalcididae: Hymenoptera] was recorded to parasitize upto 2.98 per cent whereasBrachymeria lasus Walker recorded for the first time in Kashmir was found to parasitize up to 2.01 per cent, but was not widely distributed in the State.
