Chinch-bugs and grass hoppers have also done much less damage than the. year before. The unusually warm weather of last winter caused many persons to predict the presence of an unusually large number of destructive insects during 1021. It was a wrong forecast, especially for the midwest regions. Various reasons have been attributed for the smaller number. The most common one being the fact that a killing frost occvu-red late in spring which was supposed to have destroyed a large number of insects. This may be true of the bag-worm as well as other kinds, or it may be possible that parasites caused the destruction of many injurious insects. So far as I know the cause for the smaller num- ber this year is only a matter of con- jecture. Likewise Aphidae have ap- peared in fewer numbers generally than last year, especially on out-door plants. On the other hand, the red spider has been more prevalent in my own locality than for several seasons. This may be due to the unusually long season of hot and dry weather. While insect devastations may have been less this year, growers should not be less persistent in preventing their reappearance in great numbers. A sea- son of neglect is sure to be followed by one with many new insect outbreaks. I believe we should spray and fumigate on the assumption that otherwise there will be trouble. The successful fruit grower must spray as a preventative as well as a cure for the fruit enemi
