STRAWBERRY INSECTS 375 



cover furnishes excellent winter protection to the beetles and 

 makes their control unnecessarily difficult. Whenever the 

 plants are sprayed with Bordeaux mixture for the control of 

 fungous diseases while they are in bud, arsenate of lead at the 

 rate of 4 pounds to 100 gallons should be added and would 

 probably help to decrease the numbers of beetles. Applied 

 at that time there could be no danger of poisoning the fruit. 



Some growers mow their vines soon after picking and, after 

 the tops have dried, scatter straw lightly over the field and 

 then burn it over. In this way many of the grubs are destroyed, 

 but there is considerable danger of injuring the plants unless 

 the work is done very carefully. 



Probably the best results in the control of the strawberry 

 weevil can be obtained by clean cultivation, by the destruction 

 of the hibernating quarters of the beetles, and by the planting 

 of varieties with imperfect flowers for the main crop interspersed 

 with a few rows of staminate-flowered plants or by selecting 

 profusely blossoming varieties. The other measures may be 

 used when local conditions make them desirable.

The Tarnished Plant-bug 



Lygus pratensis Linnaeus 



This inconspicuous brownish sucking plant-bug is widely 

 distributed throughout the northern hemisphere, occurring in 

 North America, Europe and Asia. It is a general feeder, 

 attacking a great variety of cultivated and wild plants. In
