In case of M. sanhorni, for example, I found the addition of soap 

 enabled either Sulphate of Nicotine or Nico-Fume to kill well down to 

 1 part in 800 or even 1,000 of water. The action of the soap seems to 

 be merely to cause the fluids to wet and spread out upon the surface 

 of the bodies of the lice instead of accumulating in drops and run- 

 ning off. 



INSECT NOTES FROM NEW HAMPSHIRE FOR 1909 



By E. DwiGHT Saxdersox, Durham, N. H. 



Insect life was unusually abundant and injurious in New Hamp- 

 shire in 1909. 



Aphids were unusually common during the late spring and early 

 summer. Aphis pomi did much more injury than usual, especially to 

 young apple trees and there were numerous complaints of its work. 

 Aphis setarice was common on cherry and plum thruout the state, curl- 

 ing the foliage very badly. 



The pear leaf blister mite {Eriophyes pyri) has been common on 

 pear for many years but has never been reported as a pest of apple 

 until the past season in which we have received several reports from 

 different parts of the state. It is interesting that New York State 

 seems to set the style in insect pests as well as in other matters and 

 that the neighboring states soon have the same troubles. The only 

 explanation of the appearance of this mite in its new role as an apple 

 pest is that suggested by Professor Parrott to me which may be due 

 to dry seasons, of which we have had three in New Hampshire. 



The apple leaf hopper {Etnpoasca mali LeB.) has been remarkably 

 abundant and has caused a speckling of the apple foliage by a seeming 

 destruction of the ehlorophyl sap. I have not been able to observe 

 any particular injuiy to old trees altho the numbers of insects have 

 caused our fruit growers some alarm. 



The spittle insect on pine (Aphrophora paraUela) was very abun- 

 dant, as in 1908, but we have been unable to relate its work in any 

 way to the so-called pine blight. Its work is of no economic signifi- 

 cance so far as we have been able to observe. The Fall web-worm and 

 other caterpillars affecting apples in late summer have continued to 

 be abundant as during the last two seasons. 



The antlered maple worm (Heterocampa guttivitta) devastated the 

 same territory as in 1908 and its injury was fully as severe. We had 

 hardly expected to see severe injury by it this year but in view of the 

 repetition of the outbreak this year we can see no reason why it may 

 not be expected to be destructive in 1910. The trees in the worst
