摘要

Laboratory bioassays were carried out to evaluate the efficacy of horticultural mineral oil (HMO) alone and in combination with neem oil, at different concentrations against egg and gravid female of Tetranychus truncatus. HMO alone, at concentrationsof 1.5, 2.0, 2.5 and 3.0% and combinations of HMO with neem oil viz., HMO (2.5%) + neem oil (2.0%), HMO (3.0%) + neem oil (2.0%) and HMO (1.0%) + neem oil (1.0%) gave 100% mortality of eggs. Adulticidal effect was concentration and time dependent. Significantly more mortality of adult was obtained with HMO 3.0% (92%) followed by its 2.5% (84%), neem oil 2%(81.33%) and the treatment combination HMO 3%+ neem oil 2% (77.33%), which were on par with each other. The study revealed that HMO possesses appreciable ovicidal and adulticidal action and is suitable for mite management.
