The electrophysiological and behavioural responses of Anomala dimidiata (Coleoptera: Rutelinae) were studied for its host kiwi plant’s (Actinidia deliciosa) three volatiles, (Z)-3-Hexen-1-ol, Linalool, and (-)-α-Pinene. This experiment comprises electroantennographic assay using EAG and field testing in the Kiwi Horticulture field using synthetic compounds. In EAG assays, all three test compounds elicit significant responses with 55.66±3.41% for (Z)-3-Hexen-1-ol, 44.97±1.08% for Linalool, and 53.75±0.33% for (-)-α-Pinene in male beetles and 54.82±3.52% for (Z)-3-Hexen-1-ol, 44.97±0.30% for Linalool and 53.75±4.69% for (-)-α-Pinene in females beetles as compare to reference compound. In the field testing, (Z)-3-Hexen-1-ol baited traps caught maximum beetles while (-)-α-Pinene-baited traps had significantly less number of beetles attracted to them. Linalool-baited traps caught 60.1% fewer beetles than (Z)-3-Hexen-1-ol baited traps but 62.7% more beetles than (-)-α-Pinene- baited traps. This study concludes that (Z)-3-Hexen-1-ol is a potential attractant host plant volatile for A. dimidiata.
