12 MONTANA EXPERIMENT STATION Bui. 133 



one year later, the subject was again briefly discussed, pointing out 

 the situation and obvious needs. In nearly every report since that 

 time we have called attention to the progress that the disease is 

 making in its spread over the state, to the seriousness of the situation 

 in the bee industry, and to the legislation needed. Nothing has 

 been done. 



Meantime, American foul brood disease has spread extensively 

 and has entered practically every important honey-producing section 

 of the state. Many beekeepers have been put out of business . Aban- 

 doned colonies of bees containing infectious material have been left 

 where the bees died, continuing to spread the malady. 



Representatives of the State Beekeepers Association called upon 

 the State Entomologist in their ofificial capacity in December, 1919. 

 asking that this office cooperate with them in an efifort to draw up 

 a suitable law and once more make an effort to have it passed by 

 the legislature. Accordingly, we are engaged in a review of the 

 various bee laws in the United States and intend to have a bill 

 ready before the next meeting of the legislature which shall have 

 the combined support of the beekeepers of the state and of the State 

 Entomologist. 



THE CODLING MOTH (CAEPOCAPSA POMONELLA LINN.) 

 The codling moth, the general insect enemy of the apple, has 

 been present in Montana for at least twenty-five years, although 

 isolated and confined largely to some of the older towns in which 

 large apple trees are growing. Considerable attention was given 

 to its habits and control in earlier years and various publications 

 have been issued from this office. With the growth of the orchards 

 in the fruit-growing sections and the development of the orchard 

 industry, this insect has come into more prominence in recent years, 

 due to the increase in its numbers under favorable conditions found 

 on the larger trees. Fruit growers in western Montana have recently 

 brought to the attention of this office the fact that the codling moth 

 occurs in injurious numbers and that it is necessary to adopt ener- 

 getic means of control. During the past year we received also letters 

 from other parts of the state asking for assistance. We believe 

 that the reason for the greater interest in this subject in 1919 was 

 due to the unusually warm season. The weather dried off and 

 became hot early in the year and made it possible for a destructive
