Methyl isoflurane prevention and treatment of rice gall midge mosquito has a significant effect, has become the Guangxi special control of rice gall midge mosquito.

To this end, we in 1989-1991 in pesticide control experiments at the same time, methyl isofenphos-induced planthopper proliferation phenomena were investigated, are reported below. 1 Materials and methods 1989, 1990 test in Nanning Suining County Pu Miao town late rice Honda, 1991 Baise Prefecture Maotou Pingtung County late rice seedling field.
