Abstract

A survey of Heliothis spp. and their larval parasitoids was conducted in the states of Andhra Pradesh and Maharashtra, India during the period 1977–1983. H. armigera and H. peltigera were recorded on safflower. H. peltigera was found dominant on sole crop, while both the species were equally important on intercrop. In general, eight parasitoids: four Hymenoptera and four Diptera emerged from the larvae of Heliothis spp. Six parasitoids were recorded from H. armigera larvae on sole crop and eight on intercrop safflower. The level of parasitism in H. armigera was higher on sole crop.

Résumé

Une enquète sur Heliothis spp. et leurs parasitoids larvaires a été effectuée au cours des années 1977–1983 dans les Etats de l’Andhra Pradesh et du Maharashtra en Inde. On a observé l’incidence à’H. armigera et H. peltigera sur le carthame des teinturiers (Carthamus tinctorius Linn.), mais tandis que H. peltigera a été plus répandu sur la culture pure, les deux espèces ont été également importantes sur les cultures associées. Dans l’ensemble, huit parasitoids dont quatre hyménoptères et quatre diptères ont émergé des larves à’Heliothis spp. Six parasitoids ont été signales chez les larves à’H. armigera en culture pure et huit en culture associée. Cependant, le niveau du parasitisme s’est avère plus élevé en culture pure.
