“…Although chemical pesticides are lethal to the target pests, they are often detrimental to the nontarget natural enemies and the surrounding ecological environment. Sex attractants based on pheromones can efficiently manage and control the pest adults in mass trapping, population monitoring, and mating disruption. − Therefore, it is important to assess the highly specific pheromone recognition system of these adults when researching olfactory systems.…”

Sex pheromones play an essential role when moths are searching for mates. Male olfactory receptor neurons (ORNs) are the primary determinant during peripheral pheromone recognition. Here, we identified the sex pheromones of a global agricultural pest, Mythimna loreyi, using gas chromatography coupled with mass spectrometry and electroantennographic detection. Nine pheromone components were identified, including (Z)-9-tetradecen-1-yl acetate (Z9-14:OAc), (Z)-7-dodecen-1-yl acetate (Z7-12:OAc), and (Z)-11-hexadecen-1-yl acetate (Z11-16:OAc), and the first two elicited electrophysiological activities in the male antennae. Trichoid sensilla were classified into four functional types on the basis of neuronal responses to pheromones by single sensillum recording. Five functional ORNs were involved in recognizing pheromones and pheromone analogues. Finally, a field bioassay revealed that a blend of Z9-14:OAc, Z7-12:OAc, and Z11-16:OAc at a ratio of 100:8.8:19.7 was highly efficient for trapping males. Our results uncover the pheromone recognition mechanism in M. loreyi and provide a novel angle for developing efficient sex attractants of pests on the basis of screening the peripheral olfactory neurons.

The intensive use of insecticides can result in environmental pollution and adverse effects on human health due to the issue of insecticide residue in the environment. To mitigate this, various control techniques, including cultural, biological, and biotechnical methods, or their combinations, can be employed to manage invasive species. One such biotechnical method that has become popular is the use of pheromones. Pheromone techniques enable early pest detection, population monitoring, mass trapping or annihilation, and mating disruption. To maximize their effectiveness, it is important to determine the exact pheromone component, optimization rate, trap design, and saturation rate for each species. In conclusion, implementing these different pheromone-based strategies is essential for providing effective pest management strategies that take regional variations in pheromones into account.

“…Four replicate pheromone solutions were prepared. The loading rate of 90 mg of ZETA per dispenser approached the commercial standard loading rate of 160 mg in Cidetrak™ mating disruption dispensers (Trece, Inc., Adair, OK, USA) [61], and reflected concentrations used in analogous work in the recent past for continuity [42].…”

Mating disruption of Cadra cautella (Walk.) (Lepidoptera: Pyralidae) using its sex pheromone components, (Z, E)-9,12-tetradecadienyl acetate (ZETA) and (Z)-9-tetradecadien-1-yl acetate (ZTA), is successful in its population management. In addition, botanical oils have extensively been investigated in stored product pest management, but the effect of synthetic sex pheromones on the mating of C. cautella in the presence of plant volatiles is still unknown. Spinosad is used in food facilities as a contact insecticide but, if C. cautella larvae burrow into food, they may escape from spinosad. Importantly, the impact of spinosad on burrowing ability of C. cautella remains unknown. Therefore, the objectives of this study were to determine the effects of sex pheromone components ZETA and ZTA in the presence of botanical oils on the mating of C. cautella and the burrowing ability of C. cautella larvae in different types of flour treated with spinosad. In the first study, male and female moths were introduced into the cubicle having botanical oils and pheromone components. The mating status of female moths and male moth attraction to the trap was determined. The control experiments had only the botanical oils or pheromones. In the second study, burrowing ability of C. cautella larvae through different flour types was evaluated over 10 d. The flour was sprayed with spinosad (treatments) or water (controls). The mating success was higher with botanical oils alone but declined with exposure to pheromone either alone or combined with botanical oils. No differences in male attraction to traps were observed in botanical only, pheromone only or pheromone + botanical oil treatments. The burrowing of C. cautella larvae differed with flour type and spinosad altered burrowing ability. Thus, we conclude that the mating and burrowing of C. cautella is influenced by its pheromone and by exposure to botanicals and spinosad.
