FOURTEENTH ANNUAL REPORT OF STATE ENTOMOLOGIST 57 



northern Montana, where no damage to speak of has been done. 

 It is not likely that this insect will be very injurious in our climate. 



The False Chinch Bug (Nysus angwstatus Uhl.). This insect 

 is rapidly becoming a pest in the State, and this year it has been 

 reported as being exceedingly plentiful in grain fields. It is often 

 mistaken for the real chinch bug and is the cause of many of the 

 chinch bug reports received at this office. In one instance this insect 

 was found in great numbers, in all stages of development, on an 

 old discarded mattress. 



The Buffalo Treehopper (Ceresa bubalus Fab.). Very often 

 a man walking through an apple orchard will notice twigs, and at 

 times most of a tree, which show a peculiar, gnarled or stunted 

 appearance. These twigs on closer examination will be seen to have 

 scars or tiny incisions, which give them a decidedly "braided" appear- 

 ance. These are the results of the tgg punctures of the buffalo tree- 

 hopper, and while the insect does not feed on the apple, these egg 

 punctures may be the cause of more or less stunting or killing of 

 twigs or whole trees. Inquiries concerning the cause of this injury 

 are frequent. 



The White Fly (Aleurodes vapor aviorwm West). The green- 

 house white fly was the cause of considerable annoyance and loss 

 to greenhouse men all over the State. Requests for control informa- 

 tion were frequent. We have known of the presence of this inbect 

 for many years. 



The Green Apple Aphis (Aphis pomi DeG.). The green apple 

 aphis was not as abundant as formerly, but was reported from 

 various parts of the State as doing slight damage to apple trees. 

 Our experience has been that this insect continues in destructive 

 abundance year after year. 



The Western Wheat Aphis (Br achy coins tritici Gill.). This 

 wheat aphis was scarce this year, being found in only one or two 

 scattered localities. The severe winter which killed off much of 

 the winter wheat, may have killed off a high percentage of the lice. 



The Woolly Apple Aphis (Schizoneura laiiigera Hausm.). This 

 injurious insect is becoming one of the most serious pests to apples 

 in the Bitter Root Valley. Owing to lack of funds it has been 

 impossible to do any work on its control.
