126 INJURIOUS INSECTS OF 1903. 



In June various Aphids or Plant Lice, not including the Grain 

 Plant Louse, began their serious work and kept at it during the 

 summer. The Currant Worm appeared on the scene in May 

 and was heard from occasionally during May and June. Cut- 

 worms began to call for attention in May, as did insects affecting 

 strawberry plants, notably the Strawberry Weevil and the Flea- 

 Like Negro Bug, both of which were heard from in June. In 

 May, too, White Grubs, the larvae of different species of Lach- 

 nosterna, began their ravages, attacking this year, barley and 

 wheat as well as lawns, and being heard from as late as August. 

 They were unusually severe this season. The Striped Cucumber 

 Beetle made his first bow just as the curtain was going down on 

 the May record. 



Our old enemy, the Chinch Bug, which I found issuing from 

 winter quarters in April, began to be heard from in July (Stearns 

 county), and from that time on was in evidence through the 

 mails until the end of the first week in August. The Grain Plant 

 Louse or Grain Aphis began to call for postage stamps about the 

 middle of July, frightening many farmers, who thought in some 

 cases that their entire wheat crop was threatened. Parasites 

 kept this pest within bovmds, and it did but little damage, al- 

 though during the latter half of July and into the first week in 

 August it was frequently heard from. Our most serious pest, the 

 Hessian Fly, added to the Entomologist's mail from July nth to 

 September 9th.
