“…The alarm pheromone identified for WFT is composed of decyl acetate and dodecyl acetate, which are produced by immature stages [ 51 ] and are emitted through anal excretion when the larva is attacked [ 60 , 61 ]. When the alarm pheromone is emitted, the other larvae quickly seek refuge in different plant structures to avoid encounters with the natural enemy [ 62 ]. The alarm pheromone can also influence the behavior of other adults, preventing them from reaching the plant [ 63 ].…”

The study of the semiochemicals of the western flower thrips (WFT), Frankliniella occidentalis, Pergande (Thysanoptera: Thripidae), is a relevant topic that spans the last two decades. Approximately a hundred articles published on this subject from 2000 to 2022 can be found in academic databases, representing approximately 5% of the research on this important pest. These topics have generated a platform for novel research with a high potential for development. However, to move on to a new research step, an effectiveness evaluation of the compounds discovered so far is necessary. This review conducted a systematic analysis of the research focused on the semiochemicals (kairomones, pheromones, and attractants) for this pest. Papers from the past three decades on WFT attraction to semiochemicals were collected from databases using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. The number of individuals attracted to compounds was extracted from the papers and compiled for analysis. With this information, an attraction ratio was calculated. Forty-one possible attractants were found in the literature, with methyl isonicotinate being the most-studied compound so far, with the third-highest attraction ratio. δ-Decalactone was the compound with the highest attraction ratio, but it was one of the least studied. A meta-analysis of the WFT choosing proportion was performed for the compounds with more trials found in the literature. The predicted mean choice percentages for methyl isonicotinate (MIN) and Lurem-TR, the MIN’s commercial product, were 76.6% and 66.6%, respectively. There was a convergence among the analyzed studies showing a high degree of research focus on the same group of nitrogen-containing compounds (mainly the pyridine structure). These findings call for future research to diversify the discovery and evaluation of attractive compounds in this relevant study area.

“…Alarm pheromones are another type of pheromone detected in the anal droplets of thrips nymphs (Teerling et al, 1993a;MacDonald et al, 2003;Suzuki et al, 2004). For example, F. occidentalis anal droplets contain the alarm pheromones decyl acetate (10Ac) and dodecyl acetate (12Ac) (Teerling et al, 1993b;MacDonald et al, 2003). These alarm pheromones repel walking nymphs and adults from the host plants, while also decreasing the oviposition rate of adult females (MacDonald, 2002).…”

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.

Western flower thrips (WFT) is one of the most economically important pest insects of many crops worldwide. Recent EU legislation has caused a dramatic shift in pest management strategies, pushing for tactics that are less reliable on chemicals. The development of alternative strategies is therefore an issue of increasing urgency. This paper reviews the main control tactics in integrated pest management (IPM) of WFT, with the focus on biological control and host plant resistance as areas of major progress. Knowledge gaps are identified and innovative approaches emphasised, highlighting the advances in ‘omics’ technologies. Successful programmes are most likely generated when preventive and therapeutic strategies with mutually beneficial, cost‐effective and environmentally sound foundations are incorporated. © 2017 The Authors.
