摘要: Sex pheromone mediated mating disruption (MD) is widely used to control codling moth 'Cydia pomonella' L. in Australian pome fruit orchards. The high concentrations of MD treated orchards interferes with sex traps for monitoring the pest. Ethyl ('E, Z')-2, 4-decadienoate (pear ester), a pear kairomone was investigated as an alternative lures sticky apple (Granny Smith and Cripps Pink) (European nashi) In orchards, ester caught significantly more moths (both sexes combined) than did 10 mg lures. Pear on average three times males females any four tested varieties at same height under treatment (i.e. +/- MD). Both were effective when placed higher tree canopy. attraction especially has great potential improve pest control. Use canopy female activity advocated.
