Summary: | Abstract
Drosophila suzukii
is an agricultural pest that predominantly harms small fruits, having a serrated ovipositor that is able to pierce the skin of ripening fruits. Its oviposition preference has been studied from various aspects including chemical and physical properties of oviposition substrates. However, its preference for certain shapes or sizes of substrates has not been explored. In this study, we tested the oviposition preference of
D. suzukii
for artificial oviposition substrates with different surface curvatures using 27 strains recently established from wild populations collected in Japan. We found that
D. suzukii
laid more eggs on a surface with smaller radii (4.8 and 5.7 mm) compared with larger radii (7.7 and 9.6 mm). We also found that the most preferred radius differed among strains. Notably, the preference was independent of the volume of substrates, suggesting that
D. suzukii
uses the surface curvature as a cue for its oviposition site selection. These results provide an additional explanation for why
D. suzukii
preferentially uses small fruits as its oviposition sites. |
