In order to study the pupation site preference which is an important component of larval behaviour, pupation height was scored in Drosophila ananassae, D. bipectinata and D. malerkotliana by using a large number of strains of these species. The mean pupation height of different strains ranged from 1.1 to 8.7 mm in D. ananassae, from 0.41 to 0.75 mm in D. bipectinata and from 1.0 to 1.3 mm in D. malerkotliana. The analysis of variance and t-test were performed to test intre- and interspecies variations in pupation height. These tests revealed significant variation among three species. Significant variations among different strains of the same species were also found in D. ananassae and D. bipectinata. These observations provide evidence for intra- and interspecies variations in pupation height in Drosophila. Variations among different strains of the same species in pupation height are attributable to genetic heterogeneity among the strains.
为了研究化蛹位点偏好（这是幼虫行为的一个重要组成部分），通过使用这些物种的大量菌株，对拟果蝇、双带果蝇和马勒果蝇的化蛹高度进行了评分。在拟果蝇中，不同菌株的平均化蛹高度在1.1至8.7毫米之间；在双带果蝇中，平均化蛹高度在0.41至0.75毫米之间；在马勒果蝇中，平均化蛹高度在1.0至1.3毫米之间。进行方差分析和t检验以测试化蛹高度的种内和种间差异。这些测试揭示了三个物种之间的显著差异。在拟果蝇和双带果蝇中，也发现了同一物种不同菌株之间的显著差异。这些观察结果为果蝇化蛹高度的种内和种间差异提供了证据。同一物种不同菌株在化蛹高度上的差异可归因于菌株之间的遗传异质性。
