ABSTRACT: The study was carried out using four botanical oils such as neem, (Azadirachta indica) pithraj, kalozira (Black camin) (Nigella sativa) and tishi (Linseed) (Linum usitatissimum) to manage red pumpkin beetle Aulacophora foveicollis attacking sweet gourd. Data were taken on the number of red pumpkin beetle on a twig per plant and fruits yield. The number of insects reduced with increasing time after spray of botanical oils. The number of insect per plant markedly reduced up to 72 hours of spray but best result was observed at 24 and 48 hours after application of treatments. For every spray the highest number of insect was observed 7 days after spray. The results of the present study revealed that among all the tested botanical oils black cumin had promising effect against the beetle at 7 days after spray. Based on the number of fruits per plant black cumin oil may be used as an effective management option against A. foveicollis.
Keywords: Black cumin, neem, Linseed, Pithraj, oils, red pumpkin beetle, Sweet gourd.
