“…The authors reported high mortality rates (90%) within 70 h, reduced fecundity, and no insecticidal activity against predators of both aphid species. Concerning the acaricidal activity, recent studies have evaluated the efficacy of different A. oleracea extracts on ectoparasitic acari (Cruz et al 2016 ; Marchesini et al 2020 ; de Oliveira et al 2021 ). Cruz et al ( 2016 ) presented high mortality rates, >90%, of the methanolic extract against larvae of Rhipicephalus microplus (Canestrini) (Acari: Ixodidae) and Dermacentor nitens (Neumann) (Acari: Ixodidae), caused by 1.6 and 6.2 mg/mL, respectively.…”

Developing sustainable control tools for managing noxious pests attacking stored foodstuffs is a timely research challenge. Acmella oleracea (L.) R. K. Jansen is a crop widely cultivated for its multiple usages on an industrial level. In this study, the extracts prepared with A. oleracea aerial parts were applied on wheat kernels for the management of eight important arthropod pests attacking stored products, i.e., Cryptolestes ferrugineus, Tenebrio molitor, Oryzaephilus surinamensis, Trogoderma granarium, Tribolium castaneum, Tribolium confusum, Alphitobius diaperinus (adults/larvae), and Acarus siro (adults/nymphs). Extraction of A. oleracea was optimized on the base of the yield and content of spilanthol and other N-alkylamides which were analysed by HPLC–DAD-MS. Two concentrations of n-hexane or methanol extracts (500 ppm and 1000 ppm), obtained through Soxhlet extraction, were tested to acquire mortality data on the above-mentioned pests after 4, 8, and 16 h and 1 to 7 days of exposure. Both extracts achieved complete mortality (100.0%) of C. ferrugineus adults. In the case of A. diaperinus adults, mortalities were very low at any concentrations of both extracts. In general, the n-hexane extract was more efficient than methanol extract against almost all species and stages. Considering both extracts, the susceptibility order, from most to least susceptible species/stage, was C. ferrugineus adults > A. diaperinus larvae > C. ferrugineus larvae > T. granarium adults > T. molitor larvae > O. surinamensis adults > O. surinamensis larvae > T. confusum larvae > T. castaneum larvae > A. siro adults > T. molitor adults > A. siro nymphs > T. granarium larvae > T. castaneum adults > T. confusum adults > A. diaperinus adults. Our research provides useful knowledge on the efficacy of N-alkylamides-rich A. oleracea extracts as grain protectants, pointing out the importance of targeting the most susceptible species/ developmental stages.

“…Spilanthol, which is included in this class of compounds, has shown, among others, a high pesticidal efficacy [ 13 ] due to its good ability to penetrate in the insects affecting the central nervous system (CNS) [ 12 ]. Agrochemical industries and research groups have also further investigated the insecticidal and acaricidal potential of A. oleracea extracts and EO against several target species of agricultural (e.g., moths, aphids) [ 14 , 15 ] and medical importance (e.g., ticks, mosquitoes, houseflies) [ 14 , 16 , 17 , 18 , 19 ]. Moving plant-based insecticides from the laboratory to the field is still difficult due to regulatory issues, though the non-target impact should be deeply studied.…”

Human pathologies, environmental pollution, and resistance phenomena caused by the intensive use of chemical pesticides have shifted the attention of the agrochemical industries towards eco-friendly insecticides and acaricides. Acmella oleracea (L.) R. K. Jansen (jambù) is a plant native to South America, widely distributed and cultivated in many countries due to its numerous pharmacological properties. This review analyzes literature about the plant, its uses, and current knowledge regarding insecticidal and acaricidal activity. Acmella oleracea has proven to be a potential pesticide candidate against several key arthropod pest and vector species. This property is inherent to its essential oil and plant extract, which contain spilanthol, the main representative of N-alkylamides. As a result, there is a scientific basis for the industrial exploitation of jambù in the preparation of green insecticides. However, studies related to its toxicity towards non-target species and those aimed at formulating and developing marketable products are lacking.
