Excerpt from Further Experiments on Mexican Bean Beetle Control Larger yield on untreated plot due to severe spray injury on sprayed plot. 1 Special test of arsenical sprays; Spray not necessary to control bean beetles. The two general periods of infestation occurred between May 26' and. June 15, during which time the over-wintering adults migrated, and be tween July 18 and August when the first generation adults emerged from pupation and migrated. Beans growing during either of these periods were injured by adults and infested by larvae of the succeeding genera tion. Those planted about June 1 were attacked by adults of the over wintering and first summer generation, but the Over - wintering adults were usually few in number, and the first generation beetles emerged just as the crop was maturing.
