Size-assortative mating in Drosophila malerkotliana
The relationships between wing size, locomotor activity, mating latency, courtship pattern and mating success (total number of pairs mated in a given time unit) were studied in pairs of Drosophila malerkotlianaMating latency was negatively correlated with wing length and with locomotor activity while wing length and locomotor activity were positively related. In trios of a female and a long-winged and a short-winged male, long-winged males mated more successfully than short-winged males. In trios of a male and a long-winged and a short-winged female, long-winged males mated with long-winged females, and short-winged males with short-winged females. In addition, in pairs of long-winged/short-winged flies, long-winged flies courted and mated more successfully than short-winged flies.
