The results of spraying operations in the course of investigations 

 into the life- history and control of the codling moth in New Mexico 

 have been described in a previous bulletin [see this Review, Ser. A, ii, 

 p. 484]. The present paper gives the results of observations into the 

 life-history during the years 1912-1915 and is supplementary to the 

 former bulletin. The records of observations as to the number of 

 generations, length of the life-cycle and its various stages during 1912 

 and 1913 are given in detail. A chart demonstrates the probable 

 effect of sudden changes of temperature on the activities of the codling 

 moth. Successful band records were made during 1913 ; these are 

 given in the form of tables and curves.

Minnesota Nursery and Orchard Inspection Law. An Act Providing 

 for the Inspection of Nurseries and Orchards. — Minnesota Insect 

 Life, St. Paul, iv, no. 4, 1st July 1917, pp. 4-8. 



The provisions of the amendment passed in 1917 to the Session 

 Laws of 1913 are given verbatim. The amendment provides that the 

 State Entomologist be appointed inspector of nurseries, his powers 

 and duties being detailed, that all nursery stock brought into the State 

 must be certified, a copy of the certificate to be filed with the Minnesota 

 inspector, that shipments must be accompanied by a certificate of 

 inspection, that transport of any uncertified stock must be refused by 

 railroad and express companies, that foreign-grown stock imported 

 into Minnesota must be inspected. Failure to comply with these 

 regulations entails certain penalties under the law of 1905. An 

 annual report is required from the State Entomologist.
