Biological Studies on the Phytosiid Predator Amblyseius cucumeris (Oudemans) Reared on the Two Spotted Spider Mite Tetranchus urtica Koch

The Effect of Copper Nano-capsules on the Control of Two Spotted Spider Mite (Tetranychusurticae)

Common bean (Phaseolus vulgaris L.) is one of the most important and widely cultivated Legume in the world. The two-spotted spider mite (TTSM), is one of the most important agricultural pests. This research provided some evidence of the applicability of CuO nano particles and nano capsule for controlling TTSM. To evaluate the effect of copper nano-capsules on the populations of TSSM from red be...

biological studies on two- spotted spider mite, tetranychus urticae, reared on nine tomato cultivars during fruiting under laboratory conditions

biological reactions of the two-spotted spider mite (tss), tetranychus urticae, were studied on nine cultivars of tomatoes. the spider mites were reared on leaf discs, taken from fruiting stages of the host plants. the effects of feeding on some tomato cultivars, namely: long shelf life, meran (greenhouse cultivars), redclude, western red, imperial, yazd, mazandaran, west azarbaijan and khorasa...

Effects of Gamma Radiation on the Biology and Population Suppression of the Two - spotted Spider Mite , Tetranychus urticae Koch Richard

Repellent effects of various cherry tomato accessions on the two-spotted spider mite Tetranychus urticae Koch (Acari: Tetranychidae).

Several studies have been conducted on resistance sources to improve the genetic resistance of farm-grown tomatoes to arthropod pests, including phytophagous mites. In the present study, we evaluate the behavior of the two-spotted spider mite on different cherry tomato accessions to identify possible sources of resistance (repellent effect) to this pest. Sixty-four accessions of cherry tomatoes...

Control 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...
