GRAPEVINE ROOT WORM 29 



was the portion just south of Mr Falvay's packing house, extend- 

 ing over a gravelly knoll into a loamy hollow. The region next 

 to the packing house contained comparatively few insects, which 

 was probably due in considerable measure to a neighbor's chickens 

 working in that section. The first 24 rows south of the packing 

 house were reserved largely for demonstrating the effectiveness of 

 collecting, and no cultivation for the destruction of pupae was 

 allowed on its six southern rows and also on the next six rows of 

 the adjacent plot. The next plot of 13 rows was sprayed with 

 arsenate of lead, 5 pounds to 50 gallons of water. The applica- 

 tion was made July 26 and special pains were taken to cover the 

 vines as thoroughly as possible. The 11 rows south of the 

 arsenate of lead plot were sprayed the same day and in the same 

 manner with poisoned bordeaux mixture, 6 pounds of copper sul- 

 fate, 6 pounds of lime and £ pound of paris green being used to 40 

 gallons of water. The next two rows were not sprayed, but were 

 left as checks, and the following 11, namely those just north of 

 the cage except one, were sprayed with an arsenate of lead mix- 

 ture as described above. The spraying with poisoned bordeaux 

 was thorough, though not quite so carefully done as in the case 

 of the arsenate of lead. At the time the application was made 

 there was a considerable evidence of feeding in the section next 

 the cages and also in that sprayed with the poisoned bordeaux 

 mixture. The row just north of the cage and that on which the 

 cages stood received no poison. 



Insects taken by the beetle catcher. The operation of the beetle 

 catcher over 5 acres resulted not only in capturing a large num- 

 ber of Fidias but also in taking a number of other species. The 

 list is of interest because it indicates in a measure the excellent 

 cultivation and care which this vineyard has received. It will be 

 observed that no species appeared in any numbers compared with 

 those of Fidia, which fact alone is of considerable value in in- 

 dicating the care and clean culture given the vineyard. A few 

 caterpillars and other soft bodied larvae were taken but in 

 relatively no larger numbers, and no attempt was made to count 

 them. The list follows, and it will be seen that the number taken 

 of any species is so small that practically all may be neglected, 

 as regards either beneficial or injurious powers.
