EcoBio-Block S, a novel controlled release system (CRS) for the insect growth regulator pyriproxyfen, uses a water-purifying concrete block system (EcoBio-Block) composed of a porous volcanic rock and cement, and it incorporates the aerobic bacterial groups of Bacillus subtilis natto. EcoBio-Block S showed high inhibitory activity against mosquito emergence as well as a water-purifying effect. Chemical analysis and bioassay showed that EcoBio-Block S provides a high-performance CRS that controls the release of pyriproxyfen at low levels according to "zero order kinetics".
EcoBio-Block S是一种用于昆虫生长调节剂吡丙醚的新型控释系统（CRS），它采用了由多孔火山岩和水泥组成的净水混凝土砌块系统（EcoBio-Block），并纳入了纳豆芽孢杆菌的需氧细菌群。EcoBio-Block S对蚊子羽化显示出高抑制活性以及净水效果。化学分析和生物测定表明，EcoBio-Block S提供了一种高性能的控释系统，可根据“零级动力学”在低水平下控制吡丙醚的释放。
