“…The O. loti has developed resistance to insecticides such as neonicotinoids, pyrethroids, and benzamides [4]. Although the application of broad-spectrum insecticides temporarily controls thrips abundance, it fails to mitigate the spread of viruses carried by thrips in the field [5]. Moreover, adverse effects on natural predators result in population resurgences that complicate thrips control [5].…”

Pheromone trapping is an interspecific, active at low concentrations, eco-friendly pest management strategy that has been widely used for population monitoring. Pheromones have only been validated for a few species in Thysanoptera and the pheromone components of Odontothrips loti Haliday are still unclear. In our study, we have identified (R)-lavandulyl (R)-2-methylbutanoate from male O. loti headspace volatiles by gas chromatography-mass spectrometry (GC-MS), which was structurally similar to the known reported aggregation pheromone of Megalurothrips sjostedti. Y-tube olfactometer assays showed that both male and female adults O. loti were significantly attracted by synthetic (R)-lavandulyl (R)-2-methylbutyrate, implicating as an aggregation pheromone. Additionally, electroantennogram responses of O. loti increased with increasing doses of synthetic (R)-lavandulyl (R)-2-methylbutyrate. This is the first report of a male-produced aggregation pheromone in O. loti, from genus Odontothrips. The discovery of aggregation pheromone of O. loti as a primary pest of alfalfa will provide the possibility of monitoring and early warning in alfalfa grass fields and is expected to be used for integrated management for O. loti.

Frankliniella occidentalisÂ Â (Pergande) (Thysanoptera: Thripidae) is an important pest in vegetable and ornamental greenhouse crops due their direct damage by feeding and indirect damage by vectoring Tomato Spotted Wilt Virus (TSWV). Also, is very well known that they have an extremely high resistance to a wide range of insecticide. Thus by monitoring thrips population appropriate control plans can be established. Western flower thrips was reported in all greenhouses from Cluj County (Romania). In order to assess thrips population dynamic and color preference we conducted a research in a plastic greenhouse of 8000 mÂ 2 placed outside of Cluj-Napoca where the main cultivated crops were tomatoes (Â Solanum lycopersicum ) and the main thrips pest found was western flower thirps. During the sample period pest population was monitored weekly using two methods: by counting thrips trapped on five different colored sticky cards (blue, yellow, white, red and transparent) and by a technique based on leaves tapping. Data analysis showed no correlation between traps and tapping method. Blue and yellow traps had the highest attractiveness compared with all the others colors and between those, blue proved to be the most effective.

Tomato Spotted Wilt Virus Infection Reduces the Fitness of a Nonvector Herbivore on Pepper

Plant pathogens and insect herbivores often share hosts under natural conditions. Hence, pathogen-induced changes in a host plant can affect the herbivore and vice versa. Even though plant viruses are ubiquitous in the field, little is known about plant-mediated interactions between viruses and nonvector herbivores. Here we tested whether the performance of the sweet potato whitefly, Bemisia tabaci (Gennadius) biotype Q, was altered when raised on pepper infected with Tomato spotted wilt virus (TSWV). TSWV infection reduced B. tabaci fecundity and longevity and increased B. tabaci developmental time but did not affect the insect's survival or female body lengths. Our results demonstrate that TSWV infection can decrease the fitness of B. tabaci biotype Q on pepper plants.
