“…The chemical structure of pheromones is widely diverse. Thus, many of them are hydrocarbons, alcohols, esters, epoxides, aldehydes, ketones, lactones, carboxylic acids, isoprenoids, and triacylglycerides [ 8 , 37 ]. This structural diversity is the key for the pheromone specificity but, in a number of species in Lepidoptera, an appropriate combination of the pheromone components in specific ratio renders the pheromone species-specific.…”

Since the first identification of the silkworm moth sex pheromone in 1959, significant research has been reported on identifying and unravelling the sex pheromone mechanisms of hundreds of insect species. In the past two decades, the number of research studies on new insect pheromones, pheromone biosynthesis, mode of action, peripheral olfactory and neural mechanisms, and their practical applications in Integrated Pest Management has increased dramatically. An interdisciplinary approach that uses the advances and new techniques in analytical chemistry, chemical ecology, neurophysiology, genetics, and evolutionary and molecular biology has helped us to better understand the pheromone perception mechanisms and its practical application in agricultural pest management. In this review, we present the most recent developments in pheromone research and its application in the past two decades.

“…Sex pheromones are mainly categorized into four Types (0, I, II, and III) according to their chemical structure 17,18 . In general, genetically related moth species produce structurally similar sex pheromone compounds with variation in the carbon chain, cis / trans ‐conformation, and number as well as position of double bonds and epoxy rings 18,19 . However, structural patterns of sex pheromone compounds of Lymantriinae species are more complicated and puzzling than those of all other moth species 11,20,21 .…”

BACKGROUND: The tea black tussock moth Dasychira baibarana Matsumura is a devastating pest in tea plantations that causes substantial economic losses. Presently, there is no effective method to control this pest other than pesticide application. The identified sex pheromone of D. baibarana could be used for detecting and monitoring this pest. RESULTS: Gas chromatography-electroantennogram detection showed that D. baibarana male moth antennae responded strongly to three components in the female sex pheromone gland, which were identified as: (3Z,6Z)-cis-9,10-epoxyhenicosa-3,6-diene (Z3,Z6,epo9-21:H) (I), (3Z,6Z,11E)-cis-9,10-epoxyhenicosa-3,6,11-triene (Z3,Z6,epo9,E11-21:H) (II) and (3Z,6Z)-henicosa-3,6-dien-11-one (Z3,Z6-21:11-one) (III). Dasychira baibarana uses a unique composition of an epoxydiene, epoxytriene, and dienone with the same 3,6-dienyl motif as its sex pheromone. The epoxytriene and dienone were not previously characterized as insect pheromone components. Electroantennogram analysis showed that each synthetic compound strongly stimulated male antennae, and compounds II and III elicited stronger responses than compound I. A wind tunnel bioassay and field trapping experiments proved that, ternary blends of compounds I-III attracted D. baibarana. Efficient attraction was achieved with a rubber septum baited with 500 ∼g of a mixture of compounds I-III at the ratio 25:20:55. CONCLUSION: The three identified compounds elicited an electroantennogram response in D. baibarana male moth antennae, and a mixture of the three components at the ratio 25:20:55 attracted D. baibarana male moths in a wind tunnel assay and field trapping experiments. This blend could be used for integrated management of D. baibarana in tea plantations.

“…Research on moth sex pheromones began about 100 years ago, and the pheromones of ca. 700 species of moths have been identified so far (Naka & Fujii, 2020;Ando & Yamamoto, 2022;El-Sayed, 2022). Typically, sexual reproduction in Lepidoptera is preceded by longdistance attraction of males and short-range courtship of females, both mediated by pheromones (Blomquist & Vogt, 2003;Roelofs & Rooney, 2003;Wyatt, 2003).…”

Pheromones emitted by both female and male moths regulate coordination between the sexes for Agriphila aeneociliella (Lepidoptera: Crambidae)

The complex and efficient sex pheromone communication system in insects is essential for reproduction and for reproductive isolation of species. In moths, sex pheromone communication starts with male attraction to compounds emitted by females; only a few species act in the reverse. However, how the pheromones that are emitted by both sexes co‐regulate and coordinate mate finding and mating remains unknown. Here, we identified both the male and female pheromones of Eastern Grass Veneer moth, Agriphila aeneociliella (Lepidoptera: Crambidae), and demonstrated their efficiency in manipulating behavioral responses of the opposite sex. Combining data from analysis of gas chromatography‐electroantennogram detection, gas chromatography‐mass spectrometry, and olfactory behavior assays, the female pheromone of A. aeneociliella was identified as (Z,Z,Z)‐9,12,15‐octadecatrienal and (Z)‐9‐hexadecenyl acetate, while the male pheromone was determined to be 1‐nonanal. Both the 2 individual components of the female pheromone and their binary mixture were significantly attractive to males, and the 1‐nonanal male pheromone induced strong electrophysiological responses in females and induced attraction of females in a Y‐tube olfactory test. Depending on the concentration of 1‐nonanal, its addition to the binary mixture of the female pheromone either enhanced (10−3 or 10−2 μg/μL) or reduced (1 μg/μL) the aphrodisiac effect of the mixture on males. In wind‐tunnel bioassays, different concentrations of pheromones, including the binary mixture of female pheromone and the mixture of male and female pheromones, had significant effects on male behavior. Our findings suggested that the blend of both female and male pheromones plays a significant role in the sexual communication system in some moths.
