six day period when the evening temperature was above 60°. It is 

 quite probable that the eggs referred to above were deposited mostly 

 during the last of June. 



Again, in 1913 he made the following record dated July 3d: " Not 

 many side worm eggs." On the 8th he observed that a few larvae 

 had entered the apples and that scattering eggs were also to be 

 found. On the 19th he states that this late side injury seem.s to 

 be distributed over a period of tim.e, adding that unhatched eggs 

 were still found and that most of the larvae entered the sides of 

 the fruit. Referring once more to the calculated evening tem.pera- 

 tures for Appleton in June 19 13 it will- be observed that they rose 

 to 60° or above on the 13th to the 17th inclusive and that there 

 was another period of moderately high evening tem.peratures from 

 the 25th to the 30th inclusive, the latter continuing to the loth 

 of July. This long period of warm evenings was undoubtedly 

 favorable to a protracted oviposition. 



In 1 9 14 the first codling m.oth eggs were found by Mr Strickland 

 June 25th, and on referring to the calculated evening records for 

 Appleton it will be noted that there was a period from the 8th to 

 the 14th when the mercury stood above 60°, while from the 15th to 

 the 20th it ranged below this figure, and from the 21st onward above, 

 this latter apparently coinciding closely with the deposition of 

 numerous eggs as noted above. The former warm period was 

 probably a little early for the laying of m.any eggs. Later, in con- 

 nection with apple inspection work, Mr Strickland recorded a 

 very large proportion of side injury in Niagara county, in some 

 instances this am.ounted to nearly 20 per cent Of the barreled crop. 

 In his judgment red fruit, especially Baldwin, king, wealthy and spy, 

 was m.ost seriously affected. 



Very few codling m.oth eggs were found by Mr Strickland June 

 14 and 15 of the past season, and on the 28th and 29th he observed 

 a few freshly laid eggs. On referring to the calculated evening 

 temperatures for Appleton, it will be seen that the m.ercury was 

 at 60° or above on the 13th to the 15th and did not remain at this 

 point and above for a series of evenings until the 30th, while on 

 July 8th large numbers of eggs were found by Mr Strickland in the 

 orchard of Mr W. Briggs of Olcott, and Mr W. H. Cowper of Newfane. 

 They were alm.ost all unhatched, though nearly ready to disclose 

 larvae, a condition indicating oviposition at about the tim.e the 

 rise in evening temperatures occurred. 



Low evening temperatures could easily check the deposition of the 

 eggs without greatly hindering the growth of the tree and such
