Abstract

Two outbred and two inbred lines of Drosophila pseudoobscura were used in mating behavior studies. For each line, mating rates were compared under both ventilated and nonventilated conditions. Under nonventilated conditions courtship and mating were earlier, not following a random rate of occurence, and females mated after fewer courtships. Flies from inbred lines tended to court and mate earlier. Under all conditions a high proportion of matings occured on the first courtship attempt.

摘要

在交配行为研究中使用了两个远交品系和两个近交品系的拟暗果蝇。对于每个品系，分别在通风和不通风条件下比较交配率。在不通风条件下，求偶和交配更早发生，并非随机发生率，且雌蝇在较少求偶后就进行交配。近交品系的果蝇倾向于更早求偶和交配。在所有条件下，很大比例的交配发生在首次求偶尝试时。
