mechanisms 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 کاملFecundity in twospotted spider mite (Acari: Tetranychidae) is increased by direct and systemic exposure to imidacloprid.
The effect of imidacloprid on fecundity in twospotted spider mites, Tetranychus urticae Koch, was investigated in laboratory experiments using individual females on bean leaf discs. Mites were directly exposed to spray formulations of imidacloprid or fed on discs cut from a systemically treated bean plant. Imidacloprid-treated T. urticae produced 10-26% more eggs during the first 12 d of adult ...
متن کاملResistance of 14 accessions/cultivars of Lycopersicon spp. to two-spotted spider mite, Tetranychus urticae (Acari: Tetranychidae), in laboratory and greenhouse
مقاومت چهارده رقم و لاین از گونه‌های مختلف جنس Lycopersicon نسبت به کنه‌ی تارتن دو‌لکه‌ای، Tetranychus urticae Koch، در آزمایشگاه و گلخانه بررسی شد. مطالعات آزمایشگاهی بر اساس دو روش زیست‌سنجی پونز (thumbtack) و دیسک برگی (leaf disk) صورت گرفت. گونه‌های Lycopersicon hirsutum و L. pennelii بیش‌ترین تعداد کنه روی پونز را داشتند. بیش‌ترین تعداد تخم (48/0 ± 15/5 تخم بر ماده در روز) رویL. pimpin...
متن کاملresistance mechanisms to chlorpyrifos in iranian populations of the two-spotted spider mite, tetranychus urticae (acari: tetranychidae)
the toxicity of chlorpyrifos to three iranian populations of two-spotted spider mite, collected from isfahan (isr), yazd (yz) and guilan (gus2) provinces were surveyed using the residual contact vial bioassay. the bioassay results showed that resistance ratios of isr and yz populations were 176.90 and 9.78 fold compared to the gus2 population, respectively. determination of esterase and glutath...
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...
