Embodiment 1

[0020] Melaleuca essential oil and lemon essential oil were mixed at a ratio of 1:7 (V:V) to obtain a compound attractant for Bactrocera dorsalis. The attraction rate to 4-5 day-old males was 3.7 times that of methyl eugenol, and to 15 Attraction rate of ~16-day-old females was 3.0%.

Embodiment 2

[0022] Melaleuca essential oil and lemon essential oil were mixed at a ratio of 1:5 (V:V) to obtain a compound attractant for Bactrocera dorsalis. The attraction rate to 4-5 day-old males was 3.8 times that of methyl eugenol, and to 15 The attracting rate of ~16-day-old females was 8.8%.

Embodiment 3

[0024] Melaleuca essential oil and lemon essential oil were mixed at a ratio of 1:3 (V:V) to obtain a compound attractant for Bactrocera dorsalis. The attracting rate of ~16-day-old females was 21.7%.
