Abstract: Bt-187 floating granule was made from Bt-187 emulsion(produced by China)and Bactimos(B.t.i-1897) floating granule was made from Bactimos wettable powder(produced by U.S.A).Bioassy showed that titre of the Bt-187 emulsion(120 I.T.U/mg)was lower than that of the Bactimos wettable powder(370 I.T.U/mg).But,titre of the Bt-187 floating granule(220 I.T.U/mg) was higher than that of the Bactimos floating granule(130 I.T.U/mg).Persistence of Bt-187 floating granule in ricefield against An.sinensis larvae was 16 days and that of Bactimos floating granule was 13 days.Therefore,Bt-187 emulsion is more suitable for producing floating granule.
摘要: 用美国Bactimos可湿性粉剂(Bti-1897)和国产Bt-187乳剂生产的两种漂浮颗粒剂灭中华按蚊幼虫的结果表明:后者对中华按蚊幼虫的效价(120ITU/mg)比前者(370ITU/mg)低,但制成颗粒剂后(效价220ITU/mg)比前者(效价130ITU/mg)高。稻田应用0.81g/m2剂量Bt-187漂浮颗粒剂控制中华按蚊幼虫,持效可达16天,Bactimos漂浮颗粒剂为13天。
