Abstract

Products Active on Mosquitoes. Part 7. Synthesis and Biological Activity of Longifolene Derivatives. -The title compounds, e.g. (I) and (II), are prepared by conventional procedures and their biological activity is evaluated on eggs and larvae of mosquito Culex quinquefasciatus. The most promising derivative (IIa) is 20 times less active than methoprene. -(SAWAIKAR, D. D.; SINHA, B.; HEBBALKAR, G. D.; SHARMA, R. N.; PATWARDHAN, S. A.; Indian J.

Anthelmintic activity in vitro of Citrus sinensis and Melaleuca quinquenervia essential oil from Cuba on Haemonchus contortus

“…All oxime ethers caused 90-100% mortality due to insect growth regulating (IGR) activity at 1 ppm. In turn, some oxime ethers were active at 0.1 ppm, causing 80-85% mortality (Sawaikar et al, 1995). A oxime ether of longifolene isolated from P. longifolia also showed juvenile hormone mimicking activities and disrupted the regular developmental pattern of larvae of the silkworm Bombyx moriand (Nair et al, 2010).…”
