HEMIPTERA. 



(Bugs.) . 



San Jose Scale in Maine. 



The following particulars concerning this pest are given by 

 Mr. E. F. Hitchings in answer to our inquiry. 



"A single, infestation of this most dreaded of all orchard pests 

 is situated in the town of Limerick. As near as can be ascer- 

 tained it was introduced about 8 years ago on one or more 

 apple trees procured from a New York nursery. The spread 

 is confined to some 20 trees in a rather isolated orchard where 

 there would be but little danger of its extending to other locali- 

 ties. As soon as the infestation was discovered, the affected 

 trees were sprayed with the lime-sulphur mixture. The orchard 

 was again visited at the time when it was thought the first young 

 would appear. It was found that a large proportion of the 

 scales was destroyed, but the young were crawling on a number 

 of the trees. The trees were then sprayed with kerosene emul- 

 sion, which killed the exposed young. It is proposed that a 

 thorough treatment will be given the orchard and followed up 

 until the infestation is entirely destroyed." 



Specimens of this long dreaded orchard pest were received 

 at the Station from Limerick, Maine, in August, 1909, for 

 determination. Most of the scales on the several twigs sub- 

 mitted were dead but there were some live and healthy speci- 

 mens. The infestation at Limerick is the first occurrence known 

 in Maine. Any one finding scales on his trees resembling those 

 shown in figures ii and 12 should send specimens to the Depart- 

 ment of Agriculture at Augusta or to the Experiment Station 

 at Orono for identification. (Lot 794.) 



Briopeltis festucae (Cottony Grass Scale). 



The white egg sacs of this insect on leaves of meadow grass 

 are an annual occurrence and were plentiful in the vicinity of 

 Orono this past season. Little complaint has been made for 

 several years by .owners of grass lands invaded by the cottony 

 scale. (Lot 770.)
