Capture of Adult Flies. The capture of adult flies is probably an effective measure in mitigating the fly-injuries. In Amabe District of Oita Prefecture, fruit-growers of the invaded \'illages capture the adult flies, at least five times every season, by Order of the District, the flies being purchased at a price agreed upon for each particular village. According to the agreement these flies are purchased by the various local offices of the invaded villages at a price ranging from 2 riu to 5 sen each.^ Thus, for example, at Aoye Village, in 1914, 78351 flies were purchased at a cost of '^«'', and at Tsugumi Village, 201675 flies for ;i'^«. The effect of the capture of these flies in reducing the fly-injury must not be under- estimated, for in the localites where the capture of flies has been carried out strictl)^ the number seen has been remarkably reduced, while at distant localities where the capture has been neglected, fruit-flies were seen abundantly in the orchards during the same season.
