In 1954-55 the author practised some control experiments against pear mite, Tetranychus pasificus, using systemic insecticides in Ichikawa and its neighbourhood. Such insecticides as Pestox 3, Systox, Meta Systox and Monofluroacetamide were applied by means of spraying, painting and injection in various period of spring and summer as shown in the tables 1 and 3. The results obtained are summarized as follows. 1) Of the three treatments mentioned above, the spraying was most effective and economical in general. 2) Spraying of Meta Systox in the early summer gave a sufficient effect. The insecticide applied once in the season was effective during the period of about one month. 3) As the practical measure for the pear mite control, the three time spraying, from May to the early July, of Meta Systox (0.1 0ilution of the emulsion) was recommended.
