“…It was also reported for menthyl acetate in German cockroaches (Alzogaray et al 2013). The results presented in this article are of relevance for surveillance and control purposes because they constitute the Þrst report of a quantitative analysis of the hyperactivity effect produced by monoterpenes in Chagas disease vectors.…”

The effect on locomotor activity, the repellency, and the knock-down produced by 10 monoterpene alcohols were evaluated on first-instar nymphs of Rhodnius prolixus and Triatoma infestans, vectors of Chagas disease. A video tracking technique was used to evaluate locomotor activity and repellency by exposure to papers impregnated with monoterpenes. Eugenol on R. prolixus and (S)-cis-verbenol on T. infestans did not modify the locomotor activity. The remaining monoterpenes produced hyperactivity on both species, although the concentration required was at least a 1,000 times higher than that of deltamethrin (positive control). Carvacrol, eugenol, and geraniol resulted as repellent as N,N-diethyl-m-toluamide (positive control) for both species. A similar result was observed for almost every monoterpene on T. infestans. Knock-down effect was evaluated by exposing the nymphs in closed recipients. The order of increasing toxicity on R. prolixus was (KT50 values in min): geraniol (213.7) < alpha-terpineol (164.5) < linalool (124.2) < carvacrol (111.6) < eugenol (89.8) < thymol (78.9), and on T. infestans: alpha-terpineol (289.8) < eugenol (221.3) < carvacrol (164.2) < linalool (154.9) < thymol (96.7). All monoterpenes were less toxic than the positive control, dichlorvos (3.6 min for R. prolixus and 3.9 min for T. infestans). After 7 h of exposure, (-)-carveol, citronellol, and menthol (on both species) and geraniol (on T. infestans) produced < 50% of knock-down. After these results, it is worthwhile to explore more deeply the potential of these compounds as tools for controlling Chagas disease vectors.

“…This indicates that no breakdown of active components had occurred, enhancing the effectiveness of the EOs. Previous reports showed that the main monoterpenes loaded in our nanoparticles produced lethal and sublethal effects in B. germanica (Jang et al 2005;Alzogaray et al 2013;Yeom et al 2013). It has been suggested that in some cases one compound within the oil is particularly toxic, while in others compounds have been shown to act synergistically.…”

Novel nanoinsecticides based on essential oils to control the German cockroach

et al. 2014

The physicochemical characterization and residual insecticidal activity of poly(ethylene glycol) (PEG) nanoparticles containing essential oils (EOs) from geranium (Geranium sp.) and bergamot (Citrus reticulata L.) were evaluated against Blatella germanica for 1 year. The nanoparticles' size increased during the storage time from \235 to \450 nm; the EO content decreased approximately 50 %, and the abundance of the major components did not show any differences between pre-and post-formulation. The surface characteristics of nanoparticles were analyzed by transmission electronic microscopy. The EO nanoparticles produced a notable increase in the residual contact toxicity apparently because of the slow and persistent release of the active terpenes. In addition, the nanoformulation enhanced the EO contact toxicity. The results indicate that these novel systems could be developed as control agents against German cockroaches.

“…Terpinen‐4‐ol is a type of terpene, a large class of organic compounds and the most representative component in essential oils . Similar to some terpenes such as 1,8‐cineole, α‐terpineol, eugenol, and linalool with high insecticidal activity, terpinen‐4‐ol showed highly fumigation activity towards stored‐grain pests . Proteomics enabled us to screen out related proteins in response to terpinen‐4‐ol fumigation at a large scale to further understand the mechanisms behind the insecticidal activity and detoxification of terpinen‐4‐ol in insects.…”
