概要

• 論文の詳細を見る

• F_1 fertility and F_2 and backcross viability of hybrids between Hokkaido form of Henosepilachna vigintioctomaculata and Sapporo form of H. pustulosa are briefly reported. F_1 hybrids of both sexes in two reciprocal combinations are fertile. The hatching ratios of eggs laid by intra-F_1 and backcrossing pairs are higher than those by interbreeding pairs reported previously. Both F_2 and backcross offspring can grow normally under laboratory conditions and their sex ratios do not significantly differ from 1 : 1.
