Summary and Conclusions

Susceptibility experiments with a strain of Wuchereria bancrofti (Cobbold) from Bora Bora in the Society Islands showed that development to advanced or infective stages occurred in the following United States mosquitoes: Culex pipiens, C. quinquefasciatus, C. erraticus, C. salinarius, Anopheles walkeri, A. punctipennis, Aedes triseriatus, A. aegypti, A. atropalpus, and Mansonia perturbans. Taking into consideration the habits and prevalence of the species, it was concluded that only Culex pipiens (83.5 per cent infected) and possibly Culex quinquefasciatus (34.9 per cent infected) were sufficiently susceptible to be dangerous potential vectors.

Anopheles quadrimaculatus, A. freeborni, Aedes atlanticus (or tormentor), and Psorophora ferox failed to develop the infection beyond the early first larval stage.
