EXPERIMENT STATIOX EEPOET. 529 



word was received that tliey had eaten up evervtlniig, but that may 

 have been soiuewhat exaggerated. At Daretown, cherries suffered 

 more than anything else ; the other fruits were also eaten to some 

 extent.' 



Mr. Dickerson's reports show that at various points throughout 

 the State roses, apples and plums were more or less injured^ and 

 there is no doubt but that there is a general increase in their num- 

 ber and in the injury caused. 



Arsenate of lead in heavy doses was tried in two instances, and 

 in one case at least with a measure of success. In the pirotectiort 

 of especially valuable plants or fruits this may, perhaps, prove 

 satisfactory, but in the protection of an orchard or vineyard the 

 expense would prohably be too great. An attempt will be made 

 next year, if possible, to test this material further. 



Plant Lice. 



Plant lice were nowhere very greatly abundant, nor did any 

 especial crop suffer seriously, yet they did attract attention on a 

 variety of plants and trees, and, on apples, were plentiful enougb 

 in a few localities to make the curled-up tips conspicuous. Other 

 species brought to our notice in the correspondence during the 

 season were on cherry, willow, hickory, elm, maple, melon, jx).tato,. 

 strawberry and rose. Of the woolly lice, those on apple, alder and 

 elm attracted attention and were reported upon. This is really an 

 exceedingly good record for the season and shows it to he one 

 decidedly unfavorable to the development of this type of insect. 



Beneficial Insects. 



ITothing was seen or heard of the Chilocorus mnilis as an enemy 

 of the pernicious scale, and no especial search was made just where 

 the insects had been placed, although examinations nearby would 

 have discovered them had there been any spread. As a check to- 

 the insect against which they were introduced they may be ac- 

 counted ai failure, and I am not aware that in other States their 

 success has been greater. 



The little Pentilia misella, on the other hand, has been present 

 everywhere, and in some places in very great numbers. Hun-
