| Abstract | Incidence of multiple paternity was investigated in the British meadow spittle bug Philaenus spumarius by using distinctive polymorphic colour patterns, which are un der genetic control of 41 crosses set up in the laboratory; 25 were successful in producing together 737 progeny. Direct evidence of multipaternal progeny was detected in 13 crosses. Twelve crosses involved at least two males’ paternity, and one cross clearly dem onstrated triple paternity in the resultant progeny. According to results, the last male may father up to 91% of the progeny, indicating the last male sperm precedence (MannWhitney (U-test, P<0.01 ) in Philaenus spumarius. Although the number of progeny (range 2-135, mean 29.48) and total copulation duration (range 6-63 hours, mean 29.00) of the multiply mated females showed variation, there was no correlation between these two variables (r= -0.292, N=25, P>0.05). Average number of the progeny did not show sig nificant difference among the females that had two or more copulations (Kruskal-Wallis, H= 3.00, df=2, P>0.05). However, the mean copulation duration of the females that had more copulations were highly significantly longer than those had less copulations (one way ANOVA: F (2,22)=Р<0.01). |
