“…It is well documented that insect behavior is guided by plant physical cues, such as color and shape, along with short-range chemical cues, such volatile organic compounds of plants, or some secretions produced by insects [19][20][21] . Our study indicates that the behavior of M. persicae was influenced by the volatiles of rosemary.…”

Volatile organic compounds (VOCs) can have an important influence on plant-insect interactions. In particular, insect behaviors are often influenced by the volatiles of both host plants and non-host plants. The objective of this study was to assess the behavioral responses of the aphid, Myzus persicae (Sulzer) to the volatiles of the woody perennial herb Rosemary ( Rosmarinus officinalis, family Lamiaceae). Our studies using a range doses of plants have shown that, at all of the different doses tested except the weight of rosemary was 0.5 g, volatiles emitted from rosemary plants showed repellent effects on M. persicae. These findings provide new insights into the interactions between R. officinalis plants and M. persicae, which will contribute to the development of new management strategies for biological control of insect pests

“…Or42b was activated by multiple components including pyrethrin II, jasmolin I and II (Table 3 and S5 None of the six pyrethrin components activated Or98a (Table 3), suggesting another compound, likely minor in the pyrethrum extract, activates Or98a. (E)-β-farnesene (EBF) (S5 Fig) and several other phytoterpenes, are found as minor components in pyrethrum extracts and contribute to the flowery fragrance of pyrethrum extract [3,34]. Therefore, we next tested if EBF could activate Or98a.…”

Pyrethrum extract from dry flowers of Tanacetum cinerariifolium (formally Chrysanthemum cinerariifolium) has been used globally as a popular insect repellent against arthropod pests for thousands of years. However, the mechanistic basis of pyrethrum repellency remains unknown. In this study, we found that pyrethrum spatially repels and activates olfactory responses in Drosophila melanogaster, a genetically tractable model insect, and the closely-related D. suzukii which is a serious invasive fruit crop pest. The discovery of spatial pyrethrum repellency and olfactory response to pyrethrum in D. melanogaster facilitated our identification of four odorant receptors, Or7a, Or42b, Or59b and Or98a that are responsive to pyrethrum. Further analysis showed that the first three Ors are activated by pyrethrins, the major insecticidal components in pyrethrum, whereas Or98a is activated by (E)-β-farnesene (EBF), a sesquiterpene and a minor component in pyrethrum. Importantly, knockout of Or7a, Or59b or Or98a individually abolished fly avoidance to pyrethrum, while knockout of Or42b had no effect, demonstrating that simultaneous activation of Or7a, Or59b and Or98a is required for pyrethrum repellency in D. melanogaster. Our study provides insights into the molecular basis of repellency of one of the most ancient and globally used insect repellents. Identification of pyrethrum-responsive Ors opens the door to develop new synthetic insect repellent mixtures that are highly effective and broad-spectrum.

“…For instance, the β-farnesene content is only 5.17% in pyrethrum flower extract. 11 In addition, farnesene can also be produced by chemical synthesis. The farnesene yield can reach about 86% by chemical synthesis; however, the product is usually a mixture of isomers and byproducts.…”

“…Farnesene production from plant extracts cannot meet the market demand because the farnesene content of plants is extremely low. For instance, the β-farnesene content is only 5.17% in pyrethrum flower extract . In addition, farnesene can also be produced by chemical synthesis.…”

Farnesene, as an important sesquiterpene isoprenoid polymer of acetyl-CoA, is a renewable feedstock for diesel fuel, polymers, and cosmetics. It has been widely applied in agriculture, medicine, energy, and other fields. In recent years, farnesene biosynthesis is considered a green and economical approach because of its mild reaction conditions, low environmental pollution, and sustainability. Metabolic engineering has been widely applied to construct cell factories for farnesene biosynthesis. In this paper, the research progress, common problems, and strategies of farnesene biosynthesis are reviewed. They are mainly described from the perspectives of the current status of farnesene biosynthesis in different host cells, optimization of the metabolic pathway for farnesene biosynthesis, and key enzymes for farnesene biosynthesis. Furthermore, the challenges and prospects for future farnesene biosynthesis are discussed.
