BACKGROUND Pheromone‐based management is a leading nonpesticidal strategy among integrated pest management options. Improving the potency of pheromone products by adding synergists would be a practical way to popularize pheromone‐based management as well as to reduce pesticide use. RESULTS Using reverse chemical ecology, synergists for Grapholita molesta sex pheromone were screened. Combined molecular docking and in vitro binding assay led to the determination of four potentially active odorants showing high affinity to G. molesta pheromone binding protein 2 (GmolPBP2). Thereafter, the high affinity between Codlemone and GmolPBP2 was further verified by exploration of GmolPBP2–Codlemone interactions. As the only sex pheromone synergist validated by both laboratory behavioral tests and field trapping, Codlemone was used to optimize commercial sex attractants currently used in G. molesta control. The recommended formulation [(Z)‐8‐dodecenyl acetate:(E)‐8‐dodecenyl acetate:Codlemone = 95:4:10] was found to trap about five to six times more G. molesta adults than the commercial sex attractant [(Z)‐8‐dodecenyl acetate:(E)‐8‐dodecenyl acetate: (Z)‐8‐dodecenol = 95:4:1]. CONCLUSION Codlemone is an excellent pheromone synergist that can be potentially sensed by GmolPBP2, which can remarkably improve the potency of G. molesta sex attractants. It is believed that the introduction of reverse chemical ecology would increase the chance of discovering pheromone synergists, promoting the development of more efficacious pheromone products that can be used in controlling G. molesta and beyond. © 2021 Society of Chemical Industry.

The objective of this work was to evaluate the potential of the essential oils of the LGRA-106 and LGR A-108 Lip pia g racili s genot y pes for the control of diamondback moth (Plutella xylostella). The lethal concentrations (LCs) were estimated by two routes of action (residual and spraying), using oil concentrations ranging from 0.5 to 3.0% v v−1, diluted in Tween 80 (1.5%). To determine the effect of the LC to 50% (LC50) on the development of P. xylostella, two compounds of the L. gracilis genotypes, thymol, and carvacrol, were sprayed on the insects. The repellency of the LC50 was evaluated by residual action, in a free-choice behavioral bioassay. The LGRA-106 genotype showed a greater toxicity via residual action (LC50 = 8.82 mg mL−1), as well as a higher repellency index. LGRA-108 was more toxic via spraying (LC50= 9.64 mg mL−1). Larval development and viability were reduced in approximately 50% with LGRA-106 or thymol and up to 70% with LGRA-108 or carvacrol, which caused mortality from 1.70 to 1.97 days after spraying. The oils of the LGRA-106 and LGRA-108 genotypes of L. gracilis have insecticidal activity in the control of P. xylostella.
