Comparative seasonal catches of sterile and wild codling moths in white delta traps baited with various lures in apple orchards under management by sterile insect treatment (SIT) alone or a combination of SIT and pheromone mating-disruption (MD).

1 SIT treatment was one weekly delivery of 4000 mixed-sex (1:1) sterile codling moths ha−1; MD treatment was 1000 Isomate-CM-Flex dispensers ha−1. 2 AA-PE lure was a single 8 mL propylene bottle with a 3 mm diameter hole in its lid containing two small cotton balls and a 5 mL load of an acetic acid plus PE mixture (240:1 µL v:v); CM-DA lure is a grey rubber septum loaded with 3 mg of codlemone plus 3 mg of pear ester (Trécé); codlemone loaded on grey rubber septa. 3 Means (n = 4) within a column and orchard treatment followed by different letters are significantly different (Tukey’s test, α = 0.05) following a significant (p ≤ 0.05) randomised block ANOVA.
