Effects of neem oil, Azadirachta indica A. juss on growth and survival of bagworm, Metisa plana (LEPIDOPTERA: PSYCHIDAE) LARVAE

Bagworm, Metisa plana Walker (Lepidoptera: Psychidae) is a major leaf-defoliating insect pest that has gained national attention due to the severe damage and loss to oil palm crops, notably in Peninsular Malaysia. The plant-derived insecticide neem, Azadirachta indica A. Juss provides a sustainable...
