The lifetime fecundity of strains JU1409, JU1410, MY1, N2 and PX174 (right hand labels) in the presence of pheromone derived from JU1410, MY1, N2 and PX174, or the no pheromone control (bottom labels). Error bars are ±1 standard deviation. Lifetime fecundity differed among the different pheromone and control treatments (d.f. = 4, χ2 = 146.4, P < 0.001) with pheromone from JU1410, MY1, PX174 and N2 significantly increasing (P < 0.001; P < 0.001; P < 0.001; P = 0.046, respectively) fecundity compared with the control treatment. Post hoc Tukey analyses showed that pheromone derived from MY1, JU1410 and PX174 are not significantly different from one another in their effect on lifetime fecundity (P = 0.08, P = 0.07, P = 1.00, respectively), whereas that of N2 is different compared to MY1, JU1410 and PX174 (all P < 0.001). There was no significant difference in the way that each strain responded to the treatments (Strain x Treatment d.f. = 27, χ2 = 15.21, P = 0.51)
