Synthetic Chemical Sex Stimulants for the Codling Moth1

The response of male codling moths (Laspeyresia pomonella) to naturally emitted host plant odours

“…Most studies have dealt with larvae and female moths, but less information is available on the responses of males to apple odours. Observations have been made on the excitation of males by odours of apple extracts (Sutherland et al, 1974), citral (Butt et al, 1968) and geraniol (McDonough et al, 1969). More recently Btida (1978) demonstrated that the odour of extracts from young apple leaves and flowers raised the level of locomotor activity of codling moth males.…”
