Abstract: The micro-structure of Trichogramma evanescens's mouthpart and hostegg is observed by the author. It's considered that Trichogramma evanescens's mouthpart is a new type of special mouthparts of insects, and hostegg supplies the needs of nutrients and respiration-metabolism for Trichogramma evanescens's larva. Therefore, hostegg can be considered as the micro-habitat for the growth and development of Trichogramma evanescens.
