402 FRUIT INSECTS 



Much may be done to lessen the number of beetles by thor- 

 oughly cultivating the vineyards while the insect is in the pupal 

 stage, the last week in May and the first half of June in New 

 York. In regions where the pest is troublesome as much as 

 possible of the land surrounding the vineyards should be kept in 

 cultivated crops and the area of waste grass land should be re- 

 duced to a minimum.

The Vine Chafers 

 Anomala lucicola Fabricius; A. 7narginata Fabricius, and others 



The beetles of this genus resemble in form their near relative, 

 the common June beetle, but are smaller, and the wing-covers 

 are usually ornamented with darker markings. At least three 

 species occasionally attack the vine. 



The larvae hve in the ground, Uving on the roots of grasses 

 and other plants, often in company with the grubs of the 

 rose chafer, which they closely resemble. They are, however, 

 smoother in appearance and are of a clear, bright, straw-yellow 

 color. The beetles emerge from the ground in spring or 

 early summer, invade the vineyard in swarms and sometimes 

 nearly defohate the vines. Their ravages may be controlled 

 by the same means as recommended for the rose chafer above.
