the trees in the summer, and by gathering and destroying the in- 

 fested fruit. 



THE GRAPE VINE FLEA BEETLE. {Graptodcra cholyhea^ Ulig-) 



The foliage of grape vines suffered severely last spring from the 

 gnav^rings of this handsome but destructive little bettle. It com- 

 mences its work in the spring on the leaf and flower buds, often 

 cutting off a large proportion of the latter. It also lays its orange 

 colored eggs in clusters on the underside of the leaves, and before 

 the beetles have entirely gone the larvae begin to hatch. The lat- 

 ter are of a yellowish or brown color, dotted and striped with black 

 and have black shining heads. They are very voracious and riddle 

 the leaves with holes. In about three weeks, having completed 

 their growth, they drop to the ground into which they burrow to 

 the depth of one or two inches and change, in an earthen cell, to 

 golden colored pupae, from which in two or three weeks the beetles 

 appear. The process of reproduction again takes place, the beetles 

 from this second brood of larvae being the ones which hibernate. 

 This is a very hardy insect and difficult to destroy except by the 

 severest measures. The most effectual plan for getting rid of it is 

 to jar the first beetles that appear in the spring into cloths spread 

 under the vines and saturated with kerosene. The beetles are most 

 sluggish on cool mornings and will drop readily, and the slightest 

 touch of kerosene kills them. The larvae may be killed by a much 

 diluted emulsion of kerosene or by syringing the infested leaves 

 with paris geeen in water, in the proportions of a teaspoonful of 

 the green to a gallon of water. 



THE GRAPE BERRY MOTH. {Eudemis botraua, Schiff.) 



A considerable proportion of grape rot in some vineyards is 

 caused by the workings of the small, slender, greenish larva of this 

 moth. The grapes infested may first be distinguished by having a 

 discolored spot on one side around the open center of which there 

 is often a slight deposit of excrement. The worm works in the 

 centre of the grape and often devours some or all of the seeds. If 

 one grape does not suffice, it works its way into a second, often 

 from mere destructiveness as it would appear; webbing together and 

 spoiling four or five. When the larva is full grown it leaves the 

 fruit and proceeds to the leaves. Here it neatly cuts out a portion 

 of the leaf for a flap, which it folds over itself and fastens down
