Resumo: Three polyvinyl chloride (PVC) formulations of fenitrothion were prepared and tested as controlled-release plastic pellets against Aedes aegypti (L.) larvae. Based on both T50(capacity to kill 50% of the larvae after 24 h exposure) and T90(capacity to kill 90% of the larvae by the end of the experiment), the nonexpanded formulation (PVC + dioctyl phthalate + fenitrothion) was more effective than either the expanded formulation (PVC + dioctyl phthalate + triton X-100 + fenitrothion) or the foamed formulation (PVC + diocytyl phthalate + triton X-100 + ammonium carbonate + citric acid + water + fenitrothion). The addition of a surfactant (triton X-100 or a surfactant (triton X-100) plus a blowing agent (CO2, produced by the reaction of citric acid with ammonium carbonate) may have increased the amount of fenitrothion released per unit time compared with the nonexpanded formulation
