Plants and microbes provide naturally occurring chemicals that are often used for the control of pests all around world. Biopesticides have been as a comparatively safer replacement synthetic pesticides past five decades. This study determined contact toxicity essential oils from Tithonia diversifolia plant against Thrips tabaci, Bemisia Aphis gosypii. The (Eos) were extracted dry leaves by hyd...

Casp. objetivo deste estudo foi avaliar a aplicação foliar óleo nim associado à terra diatomáceas sulfato manganês sobre incidência severidade míldio, produtividade rendimento pós-colheita sistema orgânico. conduzido na Epagri, Est...

The relative abundance of the reproductive types Thrips tabaci Lindeman was occasionally surveyed by collecting female adults from foliage commercially grown Welsh onions, and cabbages at various locations in Kyoto Prefecture between 2016 2018. Arrhenotokous females were found 39 46 sites coexisted with thelytokous 26 sites, which arrhenotokous composition higher than that 19 sites. type domina...

Abstract This study investigated the effect of photoperiod and temperature on bionomics three Thrips tabaci lineages (L1 L2 – leek-associated, T tobacco-associated). The experiment was performed in laboratory under following conditions: 23 °C 16L/8D 8L/16D, 15 8L/16D. Reproductive diapause detected lineage at but not L1 lineages, while all diapaused Adult longevity L1, L2, were 29.51, 25.69, 29...

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...

J. Econ. Entomol. 80(5): 1051-1056 (1987) ABSTRACT Data collected in 1983 from six commercial onion fields in upstate New York indicate that dispersion characteristics of onion thrips (OT), Thrips tabaci Lindeman, are precisely described by Taylor's power law (S2 = amb), with Ina = 0.517, SIn, = 0.059, b = 1.89, and Sb = 0.028 (n = 47; r2 = 0.99: P :$ 0.0001). Additionally, during the main peri...

With an exception of aphids, insects' 28S rRNA is thought to harbor a "hidden break" which cleaves under denaturing conditions to comigrate with 18S rRNA band to exhibit a degraded appearance on native agarose gels. The degraded appearance confounds determination of RNA integrity in laboratories that rely on gel electrophoresis. To provide guidelines for RNA profiles, RNA from five major insect...
