**Comments from Mr. Akutsu**
Drosophila suzukii is a pest for the small fruits, and causes heavy
damages on agriculture in Europe and USA. Although the oviposition
preference of this species (e.g. taste, firmness, and color) has been
investigated actively, the preference for certain size and shape has
not been investigated. In this study, we revealed that D. suzukii has
preference for the curvature of oviposition substrate, and prefer to
lay eggs on high curvature (small radius) substrate. These results
provide an additional explanation for why D. suzukii preferentially
uses small fruits as its oviposition sites.
