Life Tables of Two-spotted Spider Mite Tetranychus Urticae Koch (acari: Tetranychidae) and Its Predator Phytoseiulus Persimilis Athias-henriot (acari: Phytoseiidae)
Life table of Tetranychus urticae and Phytoseiulus persimilis on bean leaflets were studied under laboratory conditions in three seasons. For T. urticae the development time from egg to adult varied from 7 to 24 days and the highest immature mortality was 78.70 % in winter. Eggs laid by females were 88.1 eggs in autumn and 70.6 eggs in summer season. The gross reproductive rate (GRR) was the hi...
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 کاملThe 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...
متن کاملmechanisms of resistance to abamectin in two-spotted spider mite, tetranychus urticae koch (acari: tetranychidae)
tetranychus urticae koch is an injurious pest of, fruit crops, crop plants as well as ornamental plants worldwide. the high reproductive potential of t. urticae and its fairly short life cycle along with the frequent application of acaricides usually required to maintain t. urticae populations below economic thresholds, facilitates the pest's resistance to acaricides, and consequently cont...
متن کاملRemote Sensing Evaluation of Two-spotted Spider Mite Damage on Greenhouse Cotton
The objective of this study was to evaluate a ground-based multispectral optical sensor as a remote sensing tool to assess foliar damage caused by the two-spotted spider mite (TSSM), Tetranychus urticae Koch, on greenhouse grown cotton. TSSM is a polyphagous pest which occurs on a variety of field and horticultural crops. It often becomes an early season pest of cotton in damaging proportions a...
