内容 The author had some experiments regarding the pest control by using Malathon emulsion (malathon 66%) and Pestox 3 (Octamethyl phrophosphor amide 66%) in 1952〜54. The results obtained are summarized as follows. (1) Malathon gave a satisfactory effect upon various species of aphid both in laboratory and field, and it was recognized the practical consistency of the emulsion for the control was about 0.03〜0.05%.0 The emulsion (0.1 0ilution) also showed a considerable effect against larvae of Lampides boeticus (Lepidoptera: Lycaenidae) damaging broad bean in the field experiment. (2) In case of Pestox 3, the tests upon the red mite on melon and cotton aphid on egg-plant were chiefly practised, and it was recognized that Pestox 3 applied once had been effective upon the crops during the period of about one month. The required dose of Pestox 3 for the control was considered as shown in the following table. The required dose of Pestox 3 per one individual plant of crops. [table] *This figure must be several times the true required dose. In other aphid control experiment concerning trees and shrubs, however, the effectiveness of root treatment was not recognized in general, although remarkable result was obtained in the water culture of cut branches in laboratory. (3) In the control experiment upon the pear red mite by spraying, the author recognized the combination of Pestox 3 (0.1-1073754576ilution) and Malathon emulsion (0.07-1228203520ilution) gave a sufficient effect.
