Toxicity of Pogostemon Parviflorus (benth) and Polygonum Hydropiper (l) on Developemetal Stages of Red Spider Mite (oligonychus Coffeae, Neitner) (acarina: Tetranychidae) on Tea
A study was conducted during 2009-10 to assess the toxicity of chloroform extracts of Pogostemon parviflorus (Benth.) and Polygonum hydropiper (L) against red spider mite (Oigonychus coffeae, Neitner) under laboratory condition using leaf detached method. Both the plant extracts possesed the acaricidal properties on developmental stages of red spider mite. The treatment with both plant extracts...
متن کاملEffect of Plant Materials on Developmental Periods of Two Spotted Spider Mite, Tetranychus Urticae Koch (acari: Tetranychidae)
Low concentration of raw flower juice of Calotropis porcera (Asclepiadecae) and seed dust of Nerium oleander (Apocynacae) significantly delayed the egg to adult development of two-spotted spider mite, Tetranychus urticae Koch, for three successive generations under laboratory trial. The flower juice of C. porcera was found more effective than the seed dust of N. oleander in delaying the develop...

متن کاملControl of two–spotted spider mite Tetranychus urticae Koch (Acari: Tetranychidae) by some selected chemicals
The experiment was conducted to study the effectiveness of four commonly used chemicals viz., deltamethrin, cypermethrin, malathion and sulphur against two-spotted spider mite (TSSM), Tetranychus urticae Koch on potted bean plants and on excised leaf discs. Mite population remained significantly lower in all treated plots except malathion treatment. The population of T. urticae differed signifi...
متن کاملBeat sampling accuracy in estimating spruce spider mite (Acari: Tetranychidae) populations and injury on juniper.
The use of a standardized beat sampling method for estimating spruce spider mite, Oligonychus ununguis (Jacobi) (Acari: Tetranychidae), densities on a widely used evergreen ornamental plant species, Juniperus chinensis variety 'Sargentii' A. Henry (Cupressaceae), was examined. There was a significant positive relationship between total spruce spider mite densities and spider mite densities from...
