“…Thrips aggregation pheromones have been added to colored sticky traps to evaluate their biological effects in the eld (Cruz-Esteban et al, 2020; Mfuti et al, 2021). In a previous investigation involving a rose greenhouse, 1.9-to 4.2-times more F. occidentalis insects were caught by sticky traps containing Thripline™ AMS (male sex aggregation pheromone) than by unbaited traps over a 2-week period (Broughton et al, 2015).…”

BACKGROUND The stick tea thrips, Dendrothrips minowai Priesner, is one of the most important sucking pests that seriously infest tea plants (Camellia sinensis) in China. Obvious D. minowai nymph aggregation behaviors are typically detected in tea plantations. The objectives in our study were to identify D. minowai aggregation pheromones and evaluate their potential utility for controlling thrips infestations in tea plantations. RESULTS Dendrothrips minowai nymphs, females, and males were significantly attracted to nymph volatiles rather than the volatiles secreted by females and males in H-tube olfactometer assays under laboratory conditions. Our gas chromatography-mass spectrometry analysis of volatiles collected from D. minowai revealed that nymphs can produce dodecyl acetate and tetradecyl acetate. Additionally, the D. minowai females and males responded positively to dodecyl acetate, tetradecyl acetate, and the mixture (dodecyl acetate : tetradecyl acetate = 1 : 1.5) according to in behavioral experiments under laboratory conditions. Moreover, both aggregation pheromones and the mixture increased the number of D. minowai adults on sticky traps by 0.9- to 2.5-times (compared with the traps containing the solvent control) in tea plantations. Most importantly, at 10 days after adding sticky traps with D. minowai aggregation pheromones to tea plantations, the number of adult thrips per 100 leaves decreased by 57–75%, which was significantly higher than those of 39% decrease induced by the solvent control. CONCLUSION Dodecyl acetate and tetradecyl acetate were identified as D. minowai nymph-produced aggregation pheromones that can significantly attract conspecifics under laboratory conditions. More importantly, combining the aggregation pheromones with sticky traps can significantly decrease the thrips population in tea plantations. The findings of this study on thrips pheromones may be useful for developing new methods for managing thrips that do not require potentially harmful insecticides.

Currently, there are a total of 15 thrips species in the genus Megalurothrips (Thysanoptera: Thripidae). Megalurothrips sjostedti Trybom and Megalurothrips usitatus (Bagnall) are the most economically important pest species because of the serious damage they can do to leguminous crops, especially cowpea, which is an important grain crop for Africa and a vegetable crop for the rest of the world. Megalurothrips sjostedti is only distributed in Africa, while M. usitatus is widely spread in subtropical and tropical regions of the world and is more invasive. Nigeria is the only area where both thrips species are shared. Inexplicably, M. usitatus does not seriously damage cowpea in Africa. Bioecological characteristics indicated that M. usitatus adapts to a wider temperature and humidity range, which may result in its current geographic distribution. Since the 2010s, M. usitatus has received more attention and research. The integrated pest management (IPM) strategy of both thrips as case studies was reviewed in this paper, along with multiple complementary tactics, including agronomic measures, physical-chemical lure control, biological control, and chemical control, and insecticide resistance. Lessons have been learned from both M. sjostedti and M. usitatus, as well as from another widespread invasive thrips species, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), thus enhancing our overall understanding of the biology, ecology, and IPM practices of M. sjostedti and M. usitatus.
