リンゴ属野生種におけるモモシンクイガ幼虫の発育

抄録

The larval development of Carposina sasakii in the fruits of the three Malus spp. (i. e., M. robusta, M. prunifolia and M. sieboldii), which have intrinsically different fruit sizes, was examined. Irrespective of the species-specific rate of fruit growth, most larvae that had penetrated the intact fruits did not complete their development. In contrast, more than 50% of the larvae successfully completed development in harvested fruits. The results are consistent with our earlier research using 'Fuji' apples (M. domestica), and suggest the existence of common defense mechanisms of Malus spp.
