THE EEPOET OF THE

able to stand confinement on the way to Guelph. 



On this second trip we had tagged a dozen apples that had been attacked, 

 and as I was anxious to see what these looked like, and to discover what the 

 adults were doing, I visited the orchard on July 20th, about a month after our 

 second trip. The apples were now from one to one and one-half inches in diameter. 

 The tagged ones, as shown in the photograph, were badly deformed. One had 

 dropped. 



My search for adults resulted in capturing two specimens of Paracalacoris 

 colon, five specimens of Lygidea mendax and eighteen specimens of Neurocolpus 

 nubilus. The first species was taken on the shoots around the base of the tree, 

 no more of the species were seen; the second was chiefly taken in the same place, 

 but one was on some weeds in the orchard. One or two were seen up in the 

 tree but could not be caught. Of tlie eighteen specimens of Neurocolpus nuhilus

two or three were taken on the apple shoots along with the other two species, but 

 the rest were captured on the following weeds along the orchard fence: catnip, 

 mullein, teasel, cone-flower, red-raspberry (both leaves and fruit) and ground 

 cherry. A search on these and other weeds fifty or more feet away from the 

 orchard resulted in finding none of the three species though Lygus pratensis and 

 two or three other Capsids were very numerous. 



Examination of the shoots growing up from the base of the apple trees showed 

 that from two to six inches or so of the tip of almost every shoot had been 

 severely injured by the feeding of the Capsids. These shoots were to be found 

 around many trunks and in every case they had been badly injured. The injury 

 at a distance could easily be mistaken for Blight {Bacillus amylovorus) , but was 

 quite different when viewed near at hand. Some of the tips of the stem were 

 colored orange red, but whether this was due to the Capsids I could not decide, 

 especially as I had only two hours in all to spend in the orchard. 



The total amount of injury to the fruit this year would probably not exceed
