rearing work was done, but a careful search was made each spring 

 for the earliest appearance of the nymphs. A large number of 

 them were collected from time to time throughout the spring 

 and summer and brought into the laboratory for the determination of 

 the species and the several instars. The vertical lines for the blossom 

 pink, petal fall and cluster apple applications were secured from actual 

 spraying dates from six to ten orchards during these years. During 

 1917, 1918 and 1919 the dates for the applications were practically the 

 same and represent normal years. In 1920 the various sprays were 

 applied somewhat later than during the preceding years while in 

 1921 the season was much advanced and the sprays were applied from 

 three to four weeks earlier than usual. 



The data on the chart has further been corroborated by spraying 

 experiments conducted in various orchards throughout the state. Dur- 

 ing the spring of 1920 a number of tests were made in various apple 

 growing counties to ascertain if spraying in the petal fall and the cluster 

 apple periods would reduce the damages from red bugs. These sprayings 

 gave uniformly good control and the resulting injuries were small. 



Timing of Operations 



Two sprays are necessary to secure the most satisfactory control of 

 red -bugs. The apple growers should watch for the first indications of 

 foliage spotting by the nymphs and when this becomes noticeable pre- 

 parations should be made to combat the pest in the following two 

 sprays. In ordinary seasons these will be the Petal fall spray, when two 

 thirds the petals have fallen and the Cluster apple spray which is two 

 weeks later or when the young apples are the size of hazelnuts.

Common Names of Insects: — The Committee on Nomenclature of this Association 



has prepared a list of about 1,000 insects, giving both common and scientific names. 

 More than 300 common names have already been adopted by this Association, and 

 the other 700 are now under consideration by the Committee. This Hst or a portion 

 of it will be submitted to certain entomologists experienced in editorial work, former 

 members of the Committee and specialists in the different orders. The whole list or 

 any part of it will also be sent to any member on request who will carefully examine 

 it and make suggestions looking toward a greater stability in common names of 

 insects. The Chairman of the Committee on Nomenclature is Doctor Edith M. 

 Patch, Agricultural Experiment Station, Orono, Maine. ^
