Morphogenetic effects of chemical fractions of neem seeds on Mythimna separata and Cnophalocrocis medinalis, pests of rice [Oryza sativa L.] (Philippines)
1982
von der Heyde, J. | Schumutterer, H. | Saxena, R.C.
Four pure fractions of neem Azadirachta indica A. Juss seeds and two extracts caused pronounced developmental abnormalities in the larvae of the rice leaffolder C. medinalis and the rice ear-cutting caterpillar M. separata. In control of rice leaffolder, development proceeded normally. Emergence of parasites from parasitized larvae was not affected. In all treatments in rice ear-cutting caterpillar, emerging moths showed varying degrees of wing deformities. Neem seed extract also caused a marked reduction in pupal weights
