Mating behaviour, fecundity and longevity of female beetles of Xylotrechus quadripes was studied under laboratory conditions. In a single pairing event, the female approached and copulated multiply with the male (5.07 ± 1.49) and laid a batch of eggs. Following an egg laying bout the female mated again with the male and showed oviposition. This intermittent mating and egg laying continued throughout the lifespan of the female. Females that mated intermittently laid more eggs (140.72 ± 42.50) than mated singly (31.3 ± 6.08). On an average a female (intermittently) mated 12.2 times and was able to lay 140.72 ± 42.50 eggs. The maximum number of eggs per clutch was 19.3 ± 6.61 in the fourth clutch and 85.71% eggs were laid within six clutches. Later number of eggs per clutch decreased as did the frequency of mating. However, females mated multiply had significantly reduced longevity than virgins females.
