The infested fruit, as we have said above, with the exception of cherries, nearly always drops soon and the larva; finisii their develoimient in it on the ground. They are full grown in about two weeks, then enter the soil from about one-half to two inches and pupate in little oval earthen cases or chambers, which are easily broken. In about a month the new generation of beetles begins to emerge, and after feeding for some time on the fruit and foliage seeks good liiding places and hibernates. Methods of Control.

It is wise, whtaever practicable, to cut down and burn all shrubs or thickets nearby. The next step is to cultivate the orchard well as long as one may without fear of cinter injury. Cultivation destroys the pup« in the soil and also helps in other ways. The laSt stci) is to spray with a poison. Spraying is very important but no more so than. Fall or late summer Injuries on apple made by the feeding of the new generation of beetles. These injuries, though natural size, are larger than the average. (Orig- inal.)

The first spraying for apnles hiu\ pears should he with the same mixture and at the same time as the Codnug Moth spray. (See page 7). If the insects are very aoundant a second application should be given about two weeks later. In this the lime-sulphur may be
