摘要： The Asian corn borer, Ostrinia furnacalis (Guenee), is the most devastating maize pest in Myanmar. The damage caused by this pest has become a significant obstacle to farmers' income and the national economy. Control of O. furnacalis is challenging due to its protected feeding sites and the crop's height during later phases of the pest's attack. Trichogramma (Hymenoptera: Trichogrammatidae) parasitoids have been used successfully against corn borers in other countries, but knowledge on the species composition in Myanmar is limited. As a first step for potential biological control of Asian corn borer in Myanmar, Trichogramma were collected from major maize growing regions. Identification was performed based on both morphological and molecular techniques. The majority of collected specimens were identified as Trichogramma ostriniae Pang and Chen, T. chilonis Ishii, and T. dendrolimi Matsumura. This is the first report on the composition of Trichogramma species, and an important step towards the establishment of biological control against O. furnacalis in Myanmar. [GRAPHICS]
