NINTH ANNUAL MEETING. 19 



REPORTS OF STANDING COMMITTEES. 



The reports of Standing Committees being next in 

 order, the Committee on Injurious Insects was called upon 

 and reported through Professor W. E. Britton, the chair- 

 man. 



REPORT OF COMMITTEE ON INJURIOUS 

 INSECTS. 



The season of 1899 was cool and dry and, for the most 

 part, was favorable to insect development. Plant lice were 

 especially numerous. Insect attacks were probably much 

 less serious, however, on account of the preceding severe 

 winter which destroyed many plants and trees and injured 

 others. It is quite probable that many insects were also 

 destroyed and injurious forms thus kept in check. 



The Fall Canker Worm, Anisoptery pometarie Harr., 

 was less abundant at the Station than for several years. I 

 am not able to state whether or not this was the case 

 throughout the State. 



Mr, Ives reports that leaf -miners were prevalent in his 

 apple orchards during the latter part of the season. 



Scale insects have been more frequently reported to 

 the Chairman of your committee than all other insects 

 together. This is, without doubt, one of the results of the 

 agitation over the San Jos(S scale. Orchardists are now 

 looking over their trees as they never have done before, 

 and. as we should expect, are finding various species of 

 scale insects. A large scale on grape sent from Bristol 

 proved to be Lccanium armeniacum Craw., a species com- 

 mon and abundant on the Pacific coast, from where it has 

 spread into the Eastern States with considerable rapidity. 

 It usually attacks all kinds of fruit trees (especially rosa- 

 ceous fruits), and, as I have stated, it is also found upon 

 the grape. It is a large scale, oval in shape and brown in 

 color; it is quite thick and stands out from the bark.
