 duction in the number of stings in the hprvented fruit. This 

 indicates some reduction in the numbers of tie potential second 

 brood. The larvae destroyed by these bands represents a. potential 

 population in 193^ of more than 100,000 codling moth larvae figured 

 on the basis of approximately ^0 eggs per fenale. Conservatively 

 estimated, the use of -codling moth bands in a.n orchard ^''ith heavy 

 infestation is equivalent to a.t least one extra sp:^ay and the cost 

 is only a. fraction of the spray application. It '-'ould seem, there-

Possible Control for Oriental Fruit Mo th in Q,uincos 



It is generally recognized that the quince is one of the 

 most favored food plants for the Oriental F-^uit Moth. In many 

 cases ivhere the peach crop has been severely damaged, the quince 

 crop has been a total failure. The fact tY\f<t the flesh of the 

 quince does not break do^'^n allovrs a number of larvae to develop 

 in one specimen. Pr'rasites vrhich have been effective against this 

 pest on peaches have not given good result n on quinces because 

 twig growth on the quince is normally very short v^hich offers 

 little opportunity for the insect to develop, as contrasted to 

 the long period during v'hlch they can v/ork in the gro^-ang tips 

 of the peach tree. On the quince, therefore, it centers its at- 

 tention on the fruit for longer periods than on the peach and 

 once in the fruit they are beyond the reac;h of the parasite. A 

 schedule of sprays using an oil-nicotine (combination beginning 

 at the Calyx stage and applied a.t 2 week Intervals for 6 or 7 

 applications has given up to 90% clean fruit as reported in ex- 

 periments conducted in New York. (Bui. 66'9, G-eneva Agr'l. Exp. 

 Sta.). Other experiments along a. similar line are reported in

Improving the Wild Blueberry 



The 1937 Yearbook of Agriculture h.-^s recently been issued 

 by the U. S. Department of Agriculture. The general topic con- 

 sidered in this yearbook is the inproverafjnt of plrnts and animals 

 through breeding and selection. This book contains a large number 

 of Intei'esting and instructive articles. One that interested me 

 expecially is an article entitled "Improving the Wild Blueberry" 

 by Dr. Frederick V. Coville. It was written only a fe^" ^eeks be- 

 fore Dr. Coville ' s sudr^en death on January 9, I937. 



This article is a summary of his 30 years' work in improv- 

 ing the wild highbush blueberry. It tel,ls of his selection and 

 breeding work and gives much useful and interesting inf orm."tion 

 concerning the value of varieties, their- origin, descri-otion, an 

 the origin of their nar.es. Of particular interest are the notes on 

 some of the first varieties vrhich v/ere rlamed and used in Dr. CoviTfi^. 

 breeding work but ^"hich ^"ere never introduced into commercial -oro- 

 duction; also notes on 2 quite nev^ varieties, Weymouth and Dixl, 

 Anyone interested in blueberries will find this article exceedingly 

 .iteresting and instructive.
