All of the methods of preventing or overcoming Hessian fly injury are what we might term good agricultural practices. Plowing under wheat stubble, except where it bears a good stand of clover, is good practice according to the agronomist, sowing after the fly-free date is, generally speaking, the best date to sow wheat regardless of insects, and the preparation of the seed bed and use of fertilizers are good agronomic practices pure and simple. Progress has been made with so-called fly resistant wheats and one or more of the wheats which are showing promising resistant qualities likewise rank above the average in Fig. 5.—Three year old apple orchard of 1,500 trees, completely defoliated by grasshoppers. Most of the orchard under cultivation and planted to navy beans which were destroyed previous to the orchard defolia- tion. GijASSiiorricits {MeJaiiopIus fcniur-rnhnnit ct spp.) The past season we have experienced the most general and serious outbreak of grasshoppers for many years. Two years ago the grasshoppers were noticeably abundant in a few localities and in general the areas of grasshopper abundance were somewhat enlarged last year, while the past season they have appeared quite general and destructive in states where they have heretofore been of but comjiara- tively little importance. There is every reason to believe that they will continu
