Figure 1

Total numbers of adult fleas emerging from cocoa mat samples collected from simulated home environments. The black line shows total numbers of emerging adult cat fleas for untreated controls (right axis). The bars show total numbers of emerging adult cat fleas for spinosad and imidacloprid + PPF treated groups (left axis). On study days marked with an asterisk (*), the differences between emerging flea counts in the imidacloprid + PPF and spinosad groups were statistically significant (p < 0.03).
