an investigation was carried out to study the developmental time, reproduction and life table of three populations of the onion thrips, thrips tabaci lindeman, on onion (khorasan and golestan populations) and also on tobacco (mazandaran population) in the laboratory at 25â°c, 50% rh and 16: 8 h l: d. the total life cycle from egg to adult of khorasan, golestan and mazandaran populations were ga...

It has been shown that many insects have Enterobacteriaceae bacteria in their gut system. The western flower thrips, Frankliniella occidentalis Pergande [Thysanoptera: Thripidae], has a symbiotic relation with Erwinia species gut bacteria. To determine if other Thripidae species have similar bacterial symbionts, the onion thrips, Thrips tabaci, was studied because, like F. occidentalis, it is p...

28 Research on threats to pollination service in agro-ecosystems has focused primarily on 29 the negative impacts of land use change and agricultural practices, such as insecticide use, on 30 pollinator populations. Insecticide use could also affect the pollination process, through non31 lethal impacts on pollinator attraction and post-pollination processes such as pollen viability or 32 pollen...

A field experiment was conducted at Entomology farm, Sher-e-Kashmir University of Agricultural Sciences and Technology Jammu (SKUAST-J) in rabi 2020-21 to evaluate the efficacy selected insecticides against Thrips tabaci L. onion. total nine treatments viz., Acetamiprid 20 SP, Fipronil 5 SC, Emamectin benzoate SG, Imidacloprid 17.8SL, Spinosad 45SC, Thiamethoxam 25WG, Beauvaria basiana Metarhiz...

Onion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae), a worldwide pest of onion, Allium cepa L., can reduce onion yield by > 50% and be even more problematic when it transmits Iris yellow spot virus (family Bunyaviridae, genus Tospovirus, IYSV). Because T. tabaci is difficult to control with insecticides and other strategies, field studies on onion, Allium cepa L., resistance to T. ta...

Onion thrips, Thrips tabaci (Thysanoptera: Thripidae) is one of the main problems and yields limiting factors in onion fields (Allium cepa L.). In present work, an effort was made to study relative susceptibility different cultivars infestation with evaluation some chemical bio-insecticides against T. effect meteorological on its population density. The results showed that infest all tested mor...
