NOTES OF THE SEASON FROM CONNECTICUT 



By W. E. Britton, Agricultural Experiment Station, New Haven, Conn. 



During the year some interesting and rather important investiga- 

 tions have been conducted by this department. In Connecticut the 

 walnut weevil, Conotrachelus juglandis Lee, has been so destructive 

 that for several years it has been nearly impossible to obtain fruit of 

 the various imported and cultivated walnuts belonging to the genus 

 Juglans. 



In nearly all of the scanty literature this weevil is said to breed in 

 the nuts, but in Connecticut, the larvae do much greater damage by 

 tunneling in the new shoots, causing them to wither and die before 

 they can produce fruit. My assistant, Mr. H. B. Kirk, has worked 

 out the life history of C. juglandis the past summer. Very little has 

 heretofore been kno^\T;i regarding it. A bud moth, Acrobasis sp., also 

 attacks and injures the new growth and Mr. Kirk has studied this 

 insect, finding three generations each season. 



Though these studies represent only one season's work, the results 

 indicate that both the weevil and the bud moth can be controlled by 

 spraying the foliage and shoots with lead arsenate. A complete 

 account of the work mentioned above, including bibliography^, and 

 distribution of the walnut weeval in the United States will appear durin'g 

 the winter in the next report of the Station (12th Report of the State 

 Entomologist of Connecticut). 



For three years Mr. B. H, Walden has been making observations upon 

 a sawfly found defoliating cultivated blackberries in a field near New 

 Haven. A knowledge of its life history is now complete and the insect 

 being a new species of the genus Pa77iphilius was described by Prof. 

 A. D. MacGillivraj^ in Canadian Entomologist, Vol. XLIV, October,,
