Abstract: | Anopheles hilli, Culex quinquefasciatus, and Aedes aegypti were used as test insects to compare the activity of the Australian and United States strains of Culicinomyces clavosporus. To minimize the variability incurred by using different larval batches, both strains were bioassayed at the same time using one batch of larvae. Six pairs of assays for each of the three test species were conducted in this manner. It was found that there was no difference in potency of the two strains in any one of the three species. A between species comparison, with the data pooled for both strains, showed that A. aegypti was more susceptible to the fungus than A. hilli. The susceptibility of C. Quinquefasciatus appeared to be intermediate but the fiducial limits of the weighted mean LC50 overlapped with those of the other two species. From the results of these experiments it would seem that, with regard to potency, both strains of Culicinomyces may be equally promising for the biological control of mosquitoes. |
