CANE BORER. 



{Anffphicerus hicaudatus Say.) 



A small cylindrical beetle, Avhich works as a borer in its mature 

 stage. It injnres the grape by bnrrowing into the stems in spring 

 near the base of the new growth. It breeds in the dying wood. 

 The larva sometimes feeds upon the grape vines. 



Treatment. — As it breeds in the dying wood, careful cutting 

 away and destroying of such wood will help to check the insect. 



GRAPE-VINE FLEA-BEETLE. 



(Ilaltica cliahjhea 111.) 



Description. — The adult insects arc shining steel-blue flea- 

 beetles measuring about one-fifth of an inch in length. They live 

 during the winter under the bark of the old vines or in rubbish in 

 t4ie fields. They emerge from their winter quarters during the 

 first warm days of spring, and feed upon the opening buds and 

 young leaves. Egg laying begins late in April or early in May. 

 The eggs arc placed singly near the buds or upon the leaves and 

 hatch- in about ten days. The young larvae are dark brown in 

 color but soon become prominently marked with black dots and 

 patches. They are full growm in from three to four weeks at 

 which time they measure about a quarter of an inch in length. 

 They feed on the leaves, devouring only the soft parts at first, but 

 finally eating irregular holes through the leaves. When ready 

 to pupate they go a short distance into the ground. The adults 

 emerge from these pupa3 during the latter part of June or early in 

 July. They probably feed during all of the summer, finally seek- 

 ing shelter for the winter as above indicated. 



Treatment. — The vines should be sprayed with Paris green, 

 one pound to fifty gallons of lime and water, just before the buds 

 begin to swell. Much pains should be taken to make this appli-
