Strickland, inspector of the Department of Farms and Markets, 

 show an interesting correlation between high evening temperatures 

 and oviposition by this very injurious insect. 



Field tests were also conducted to determine the possibility of 

 destroying the moths before they laid their eggs by spraying the trees 

 thoroughly with a nicotine preparation, other insecticides being simply 

 incidental to the main purpose. Work of this kind was conducted 

 on the farm of Mr L. L. Morrell, Kinderhook, and that of Mr R. E. 

 Heard, Lockport. The spraying on this latter was under the super- 

 vision of Mr Strickland and a canvass of the results shows a decided 

 improvement following the application. The data amply warrant 

 the continuation of work along this hne. 



The series of experiments to determine the relative efficiency of 

 the several sprays for control of codling moth have been continued 

 in the western part of the State and the data in relation thereto are 

 given in a general discussion of the codling moth work. 



Observations relating to the following insects are based on field 

 work and reports by the Entomologist and his correspondents. 



Apple maggot. It was not possible to continue the field work with 

 this insect, though it happens that the orchard sprayed with poison 

 late the preceding season was gratifyingly free from injury last 

 summer. There was no spraying the past season and the fruit was 

 very severely damaged. This alone suggests that a late application 

 of poison at the time the flies are issuing is the most promising method 

 of controlling the pest, particularly since similar results have been 

 obtained by other workers. 



White-marked tussock moth. The past season has been note- 

 worthy because of the unusual abundance of the caterpillars in 

 orchards and the consequent general and rather serious damage to the 

 fruit. It was this insect rather than the leaf roller which injured 

 most of the apples in many localities. 



Red bugs. Injuries by red bugs are becoming increasingly abund- 

 ant here and there in the State. Fruit growers suffer considerable 

 losses from these pests and frequently secure only indifferent results 

 in control work due to variations in the time of hatching of the bugs 

 and the further fact that spraying, in order to give the best results, 

 must be done while the bugs are small and their work relatively 

 inconspicuous. 



San Jose scale. This serious pest of earlier years has attracted 

 comparatively little attention the past two seasons. Spraying with 

 jime-sulphur wash at winter strength has uniformly resulted in
