(6)这表明白化病可能不仅影响逃离水，而且影响其他形式的行为。先前的研究已经揭示了A品系在避免电击的测试中无法学习跑步反应，并且在压力或厌恶的情况下倾向于低活动（冻结）和高情绪排便率（7）;我们的水逃逸测试也是对厌恶刺激的主动反应的测量。所有这些研究结果一起表明，白化病可能与一般的方式与活动，或与厌恶刺激的反应。其他菌株（6），表明白化病可能不仅影响逃离水，但其他形式的行为以及。先前的研究已经揭示了A品系在避免电击的测试中无法学习跑步反应，并且在压力或厌恶的情况下倾向于低活动（冻结）和高情绪排便率（7）;我们的水逃逸测试也是对厌恶刺激的主动反应的测量。所有这些研究结果一起表明，白化病可能与一般的方式与活动，或与厌恶刺激的反应。模糊的声音Persimilis果蝇的活动范围沿着美国西部海岸的大部分地区，并且几乎完全包含在D.伪暗与D. pseudobscura、拟暗纹叶蝉D. Persimilis通常在较凉爽、较潮湿的生境中发现，并且在早上相对较活跃，而在晚上较不活跃。这两个物种有不同的食物偏好。然而，这两个物种的自然发生有很大的重叠;两个物种的交配种内对可以同时从同一食物来源收集（1）。杂交种在自然种群中极为罕见（低于1/1000）。虽然杂交在实验室中出现，但部分性隔离仍然存在。因此，必须有在近距离有效的孤立因素。在这方面，求爱行为的差异特别令人感兴趣。振动一个或两个翅膀是果蝇求偶中非常常见的行为。模糊的声音Persimilis果蝇的活动范围沿着美国西部海岸的大部分地区，并且几乎完全包含在D.伪暗与D. pseudobscura、拟暗纹叶蝉D.

(6), suggesting that albin-ism may influence not only escape from water but other forms of behavior as well. Previous investigations have revealed an inability of the A strain to learn a running response in a test of avoidance of electric shock, and a tendency toward low activity (freezing) and a high rate of emotional defecation in a stressful or aversive situation (7); our water escape test is also a measure of an active response to aversive stimulation. All these findings together suggest that albinism may be associated in a general way with activity, or with responsiveness to aversive stimuli. other strains (6), suggesting that albin-ism may influence not only escape from water but other forms of behavior as well.

The range of Drosophila persimilis extends along most of the western coast of the United States and is almost entirely contained within the more southerly and easterly extending range of D. pseudoobscura. Compared with D. pseudoobscura, D. persimilis is generally found in cooler, more moist habitats and is relatively more active in the morning and less active in the evening. The two species have somewhat different food preferences. However , there is wide overlap in the natural occurrence of the two species; copulating intraspecific pairs of the two can be collected simultaneously from the same food source (1). Hybrids are extremely rare in natural populations (less than 1/1000). Though hybrids occur in the laboratory, partial sexual isolation persists. Thus there must be isolating factors effective at close range. Differences in courtship acts are of special interest in this context. Vibration of one or both wings is a very common act in Drosophila courtship. liminary sounds.
