  1. Bold indicates significance at α = 0.05. (Model fit assessed by value of deviance per degrees of freedom: larval survival = 1.450, vector density = 0.934, adult survival = 8.967, gonotrophic cycle = 0.765). P-values are reported only for significant interactions and first order terms. Table reflects the final output of a backwards-eliminated full factorial model. N.S. = not significtant, N.A. = not applicable, a = SPSS unable to compute due to numerical issues.
