The relation of fruit diameter to degree of control is 

 y;911 illustrated by these figures from Prof. I'/liitcomb. Mcintosh 

 apples sprayed when the average diameter v/as A/l^-i^ch showed 

 13.3/b curculio injury. Other apples sprayed v;h.en 5/16- inch in 

 diameter showed only L^.'S injury, while 6/16-inch fruit showed 

 12.8/j injur;/. In other v/ords^ the curculio did about 3 times as 

 much damage on fruit sprayed v/hen 1/16 of an inch larger or 

 smaller than 5/16. Other varieties sho\/ed smaller differences.. 

 The corresponding figures for Gravenstein sprayed when diameters 

 were 4/16, 5/16, and 6/ 16-inch, were 29.6f&, 13.4/"^ and 37.5^, 

 respectively. 



Vflien Do Apple Maggot Flies Smerge? 



In the March issue of Fruit iJotes we shall show by 

 graphs the 1940 emergence of maggot flies in three sections of 

 the wortheast, - Massachusetts, Connecticut and the Hudson Valley. 

 Growers often express the opinion that flies are emerging later 

 than is commonly supposed, since they are observed in the tr^es 

 as late as mid-September. The above mentioned data seem to shov; 

 that the majority of the flies emerge before the first of August. 

 Damage to late varieties is apparently due in many cases to flies 

 migrating from other trees. 



gffects of Stacking Mcintosh Apples " on the Bulge" 



To measure the damage caused by careless handling of 

 packages, the following experiment v/as performed at the State 

 College a few weeks ago: Fancy Mcintosh apples, 2^-" and up, were 

 jumbled with high bulge (3/4 to 1") in iiortheastern crates and 

 stacked four high on the bulge . The crates v/ere moved three 

 times, handling without undue roughness. The bottom crate which 

 contained 131 apples v/as checked for bruises on January 14 v;ith 

 these results: 21 apples had stem punctures; 36 had major bruises 

 (| to 1%" in diam.); 59 had less serious bruises (1/8 to 3/4" in 

 diam.); 15 apples v/ere free from injury. 



Do You &10W 



That California produces about 88/j of the nation's 

 grape crop? 



That the "United States produces about one-third of the 

 apple crop of the world? France occupies second place and Germany 

 third, in apple production. 



That there are nov; more tlian 2500 food locker storage 

 plants in the U. S.? Iowa leads v;ith 450 and V.'ashington is second 

 with 325. 



That canners iiad on hand Feb. 1, about 2,000,000 cases 

 of sour cherries? This is nearly double the normal supply. 



That the total production of tlie 15 important fruits 

 in the United States in 1940-41 is estimated to be cbout 13.7 

 million tons compared with I4.4 in 1939-40 and the 1934-38 average 

 of 12.6 million tons?
