the first generation was practically controlled. Possibly the larvae 

 feed on the leaves to a greater extent in New Hampshire than in 

 Colorado. In Grand Valley in Colorado in 1907, the entomologist 

 kept track of the climatic conditions and the growers were notified by 

 circulars, telephone or telegraph, so that the spraying was done at 

 exactly the right time. The results that were secured in Colorado 

 agreed in general with those of Dr. Ball in Utah. 



]\Ir. Headlee stated that the apple crop was an absolute failure this 

 year in Kansas and asked if there would be codling moths next year. 

 In reply Mr. Quaintance said that the moth was supposed to have been 

 exterminated in a small valley in California in this manner. Profes- 

 sor Garcia is now conducting an experiment of this kind in New 

 Mexico. 



Mr. J. B. Smith called attention to the fact that the pupae of Lepi- 

 dopterous insects that are normally single brooded sometimes pass the 

 winter in that stage. If this was occasionally the case with the cod- 

 ling moth, the species might be carried over in this way. 



Mr. Taylor mentioned the entire absence of codling moth eggs in 

 orchards that were barren in 1907, though badly infested in 1906, 

 when a full crop of fruit was borne. 



Mr. Fletcher remarked that he had once carried this insect over the 

 second winter in the pupa form, but the specimen was kept in his 

 office. 



Mr. Quaintance presented the following paper : 



NOTES ON THE LESSER APPLE WORM, ENARMONIA 

 PRUNIVORA WALSH

Mr. Sanderson asked if the work of this insect can be distinguished 

 from that of the codling moth larva. Mr. Quaintance replied that the 

 larvse work to a considerable extent in the calyx basin, boring holes 

 into the flesh from one fourth to one-half an inch deep around the 

 calyx and eating out the flesh under the skin in the calyx cavity ; and 

 also on the sides of the fruit, especially where touched by another 

 apple or a leaf. Except as the fruit is nearly ripe, larvte rarely pene- 

 trate to the seeds, as is done by the codling moth larvffi. The lesser 

 apple worm, when full grown, is about the size of a half grown codling 

 moth larva, but is somewhat fusiform in shape and is flesh-colored, or 

 pinkish. On the caudal portion of the anal segment there is a small
