“…After plant volatiles are collected, they are usually identified with gas chromatography-mass spectrometry (GC-MS) with examples for trap crops including Erigeron annuus (Halloran et al, 2013), Brassica rapa (Thoming et al, 2020), andTrifolium repens (Allsopp et al, 2022). Sunflowers (Helianthus annuus L.: Asteraceae) have been used as trap crops to control yellow peach moth, Conogethes punctiferalis Guenée (Lepidoptera: Crambidae), which is one of the most common fruit borers causing damage to peach, pear, and Chinese chestnut (Deng et al, 2019) in orchards in China (Figure 1; Wan et al, 2016Wan et al, , 2019. Our previous study found that the planting of trap crop sunflowers decreased the abundance of C. punctiferalis populations by 39.4%-48.1% in orchards (Wan et al, 2016).…”

Sunflowers (Helianthus annuus) are potential trap crops to attract the yellow peach moth (Conogethes punctiferalis) in orchards but the volatile compounds released from sunflowers and their effects on C. punctiferalis behaviour are not clear. Here we used solid phase micro‐extraction to collect volatiles released from flower disks of sunflowers, identified them by gas chromatography–mass spectrometry, and examined the attractiveness of some of the compounds to mated female adult C. punctiferalis moths in Y‐tube olfactometer choice tests. We detected nine volatile compounds (α‐Pinene, β‐Phellandrene, Camphene, β‐Pinene, 3‐Carene, D‐Limonene, Eucalyptol, γ‐Terpinen, and Valencene) with consistently large peak areas for α‐Pinene and β‐Phellandrene. Among tested volatiles, both α‐Pinene and β‐Phellandrene were attractive to C. punctiferalis in olfactometer tests but this was only significant for higher concentrations of β‐Phellandrene. This suggests that β‐Phellandrene may promote C. punctiferalis oviposition on sunflower disks. This study provides insights into volatile chemical mediated responses of insect herbivores to trap crops.
