[0001] The invention relates to an insect attractant, in particular to an attractant for Bactrocera dorsalis. Background technique

[0002] Bactrocera dorsalis Hendel is an omnivorous insect. Its adults lay eggs in the peel, and the larvae eat in the pulp, often causing the fruit to rot or fall off before it is ripe, seriously affecting the yield and quality of the fruit. , and some even completely lost their food value.
