Effect of Aedes albopictus aggregation on an index of performance λ′ for 80-larva cohorts of A. albopictus. Horizontal bars are means of N=4 observations, and open circles are individual replicates for block 1 only (See text). Randomization ANOVA (Cassel 2002) is significant (P<0.0001). Means associated with the same letters are not significantly different by pairwise unequal variance t-tests, with Bonferroni adjustment for 6 tests.
