Efficiency of some Jasmonic Acid Concentrations on Mortality of Two-Spotted Spider Mite Tetranychus urticae Koch on Eggplant

چکیده
Abstract The efficiency of Jasmonic acid concentrations 0, 5, 50 and 100μM was examined mortality adult female nymphs the two-spotted spider mite Tetranychus urticae fed on leaves over four time intervals 12, 24, 36 48 hours. results showed significant effect treatments corrected ratios for both stages, as well interaction variety, concentration time. In general, indicated increase with period. It observed that during periods all varieties 50μM after hours Barcelona variety 5μM last two Bowie had highest ratio, which 100%, while lowest ratio 0% at 12 treatment females Jawaher variety. Regarding nymphal stage, triple between 5 μM a synergistic along in obtaining individuals stage (100%) differences from other same achieved nymph amounted 0%.

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...

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...

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...
