This is the first record of endoparasitic Hymenoptera Apanteles galleriae recorded from Apis cerana colonies in Korea. A simple rearing protocol was established to allow the morphology, mating behavior and infestation rate of A galleriae. In total, 55 lesser wax moth fresh cocoons were kept in the tissue culture test plate at room temperature (25.6 ± 1.5˚C, RH 21 ± 3.7%). The females were 3.4 ± 0.3 longer than male 3.3 ± 0.2. The male antenna was longer than females. The copulation lasts 24.4 ± 2.4 seconds. The larvae of A. galleriae were pupated inside the cocoons of lesser wax moth. Ninety percent of adults A. galleriae was successfully emerged from the lesser wax moth cocoons. A. galleriae can be used as bio-logical control in store and in live colonies to control lesser wax moth.
