NINETEENTH ANNUAL MEETING 147 



less conspicuous than those of the green apple aphis. The 

 former are often hidden around the buds of the fruit spurs 

 and the latter are usually found on the bark of the terminal 

 twigs. The cherry aphis, Mysus ccrasi Fabr., and the green 

 peach aphis, Myzus persicae Sulz., were also abundant and 

 did more or less damage, as did also many other species of 

 aphids. 



In spite of warnings given at this meeting last year and 

 sent out from the Experiment Station, many apple orchards 

 in the state were completely stripped by canker worms, and 

 it was not until after the damage had been done that the 

 owners were aroused over the matter. Nevertheless, a num- 

 ber of good demonstrations were made in various parts of 

 the state where the owners protected their orchards satisfac- 

 torily by spraying. The result was good fruit and a good 

 profit. All fruit growers who expect to get a crop are 

 warned to spray early with lead arsenate next year, especially 

 in those localities where the canker worm was abundant last 

 season. 



Red-humped caterpillars, Schicura concinna S. & A. and 

 Datana caterpillars, Datana ministra Drury, have been com- 

 mon during late summer and fall and have stripped many 

 small trees. The cherry or pear slug, Eriocampoidcs limacina 

 Retz., has been sent in several times, and the hag moth, Pho- 

 betron pithecium S. & A., once. All of these feed upon the 

 leaves and can be easily controlled. 



The San Jose scale has been present in about the usual 

 quantity, though in some orchards there are indications that 

 it is becoming less virulent. The commercially prepared lime 

 and sulphur mixtures are being used rather extensively and 

 are fairly satisfactory. In general they should be used some- 

 what stronger or less dilute than the manufacturers advise. 



The most important entomological fact that your com- 

 mittee can report at this time is the discovery of the gypsy 

 moth at Wallingford, which was made known December 14th. 

 This insect has been present at Stonington, where control 

 measures have been enforced for four seasons, and the pest
