Average positive containers to larvae per house (C+/H) and their 95% confidence intervals (95% CI) in basal conditions and also after treatment in the four house blocks

TreatmentC+/H Basal95% CIC+/H after treatment95% CI
*One way analysis of variance (ANOVA) for basal C+/H between the four house groups: F=3.56, p<0.05. In this case the Tukey test post ANOVA demonstrated that the most significant difference was found between C (EC plus chemicals) and D (only EC), with p<0.01; †one way ANOVA for C+/H post treatment in the four groups demonstrated a F=8.03, p<0.0005, with an increased difference between C (EC plus Chemicals) and B (Control), demonstrated by the Tukey test post ANOVA, p<0.0001; ‡Student's t test for C+/H Basal v C+/H Post treatment in all the groups: t=2.52, df=186, p<0.05 (two tails).
