Effect of watermelon silver mottle virus on the life history and feeding preference of Thrips palmi.
PLOS ONE, 2014Co-Authors: Wei-te Chen, Chien-hao Tseng, Chi-wei TsaiAbstract:Thrips-borne tospoviruses cause numerous plant diseases that produce severe economic losses worldwide. In the disease system, Thrips not only damage plants through feeding but also transmit causative agents of epidemics. In addition, Thrips are infected with tospoviruses in the course of virus transmission. Most studies on the effect of tospoviruses on vector Thrips have focused on the Tomato spotted wilt virus–Frankliniella occidentalis system. Thus, we focused on another Thrips-borne tospovirus, Watermelon silver mottle virus (WSMoV), to examine the effect of virus infection on its vector, Thrips palmi. In this study, the direct and indirect effects of WSMoV on the life history traits and feeding preference of T. palmi were examined. The survival rate and developmental time of the WSMoV-infected larval Thrips did not differ significantly from those of the virus-free Thrips. Comparing the developmental time of larval Thrips fed on the healthy plants, Thrips-damaged plants, and Thrips-inoculated plants (the WSMoV-infected plants caused by Thrips feeding), feeding on the Thrips-damaged plants reduced the developmental time, and the WSMoV infection in host plants partially canceled the effect of Thrips damage on the developmental time. In addition, no significant variations between the virus-free and WSMoV-infected adult Thrips regarding longevity and fecundity were observed. These results implied that WSMoV did not directly affect the life history traits of T. palmi, but the WSMoV infection indirectly affected the development of T. palmi through the virus-infected plants. Furthermore, feeding preference tests indicated that T. palmi preferred feeding on either the Thrips-damaged plants or the Thrips-inoculated plants to the healthy plants. The effect of tospoviruses on the life history and feeding preference of vector Thrips might vary among host plants, virus species, vector species, and environmental factors.

Fumigant effect of essential oils on mortality and fertility of Thrips Frankliniella occidentalis Perg
Environmental Science and Pollution Research, 2019Co-Authors: Elena Stepanycheva, Taisiya Chermenskaya, Mariya Petrova, Roman PavelaAbstract:The western flower Thrips ( Frankliniella occidentalis Perg.) is one of the most economically important insect pests of greenhouse plants. Plant protection against this pest is based predominantly on synthetic insecticides; however, this form of protection poses problems in terms of Thrip resistance to the active substances, along with health risks associated with insecticide residues on the treated plants. Therefore, new active substances need to be sought. Essential oils could be a new, appropriate, and safe alternative for greenhouse culture protection. As greenhouses are enclosed areas, fumigation application of EOs is possible. This paper presents acute toxicity results for 15 commercial EOs applied by fumigation, as well as the effect of sublethal concentrations on fertility of F. occidentalis females. The most efficient EOs were obtained from Mentha pulegium and Thymus mastichina , with LC_50(90) estimated as 3.1(3.8) and 3.6 (4.6) mg L^−1 air, respectively. As found for the very first time, sublethal concentrations of EOs could result in a significant reduction in the fertility of surviving T. occidentalis females. Among the tested EOs, the EO from Nepeta cataria provided the highest inhibition of fertility, with EC_50(90) estimated as 0.18 (0.36) mg L^−1 air. Chemical composition of the most efficient EOs and possible applications of the results in practice are discussed. In conclusion, in light of the newly determined facts, EOs can be recommended as active substances for botanical insecticides to be applied against Thysanopteran pests by fumigation.

evaluation of soybean for resistance to neohyadatoThrips variabilis thysanoptera Thripidae noninfected and infected with soybean vein necrosis virus
Journal of Economic Entomology, 2020Co-Authors: Doris Lagoskutz, Michelle L Pawlowski, J S Haudenshield, J Han, Leslie L Domier, Glen L HartmanAbstract:Soybean vein necrosis virus (SVNV) was first identified in Arkansas and Tennessee in 2008 and is now known to be widespread in the United States and Canada. Multiple species of Thrips transmit this and other tospoviruses with NeohydatoThrips variabilis (Beach) (soybean Thrips) cited as the most efficient vector for SVNV. In this study, 18 soybean, Glycine max (L.) Merr., genotypes were evaluated in four experiments by infesting plants with noninfected and SVNV-infected Thrips using choice and no-choice assays. In both choice experiments with noninfected and SVNV-infected Thrips, the lowest number of immature soybean Thrips occurred on plant introductions (PIs) 229358 and 604464 while cultivars Williams 82 and Williamsfield Illini 3590N supported higher counts of mature Thrips. The counts between the two assays (noninfected and SVNV-infected Thrips) were positively correlated. In both no-choice experiments with noninfected and SVNV-infected Thrips, counts of Thrips did not differ by soybean genotypes. Further studies are needed to characterize the inheritance and mechanisms involved in the resistance found in the choice assay.
