168 ANNUAL REPORT OF THE Off. Doc. 



effective or satisfactory. It was foimd also in opening and exam- 

 ining recently fallen fruit that the majority of the larviB of the 

 Codling Moth leave the apples before the fruit drops from the 

 tree, even though it should fall v^hen quite green, as in the middle 

 of the summer, A study of the weight of the green fallen apples 

 which were infested, compared with the weight of those not in- 

 fested, but also fallen, showed that the latter weighed 12 per cent, 

 more than the former. Another very interesting point is the proof 

 that the abundance of the Codling Moth in the fallen fruit gradu- 

 ally increased from the first of July, when the work was under- 

 taken, until the twenty-fifth of that month, when it gradually de- 

 creased until the latter part of August, when no more dropped 

 fruit was found infected with this insect, although the apples 

 continued to drop from various causes. These facts emphasize the 

 value of other measures, such as spraying with arsenites, when the 

 blossoms drop, in order to destroy the Codling Moth, rather than 

 depending upon the destruction of fallen fruits or the banding of 

 trees.* 



(6.) PUBLICATIONS: 



(a) The Monthly Bulletin of the Division of Zoology. — Among 

 the publications of this office there has been a monthly bulletin 

 of thirty-two pages devoted to the practical measures that should 

 be followed during each respective month of issue in order to 

 preserve crops against the effects of diseases, the depredations of 

 insects and higher animals, and also to preserve our fish, game and 

 insectivorous birds, beneficial raptorial birds and other beneficial 

 creatures. 



The demand for this bulletin has been so great that our mailing 

 list is now over twenty-four thousand, or within less than one thou- 

 sand of the maximum limit, which the law permits printed. In 

 order to serve all of our citizens who are calling for this practical 

 publication, it will be necessary for the next session of the Legisla- 

 ture to provide for the publication of a larger issue. Its distribu- 

 tion has been confined to those who have requested it, and thus I 

 can assure you that it is not scattered broadcast over the State 

 to be lost, but is placed only in the hands of persons who desire to 

 read and use the information therein contained. 



The calls for these Bulletins have been from persons engaged in 

 every pursuit in life. They have not by any means been confined 

 to farmers and fruit growers, and a list of the professions or pur- 

 suits indicated by the letter-heads of our correspondents will em- 

 phasize this point. I have been pleased to send the Bulletins to 

 persons without regard to any qualifying features whatever, not 



•since the above was written a Report upon these Studies of the Codiin^ Moth has been sub- 

 mitted to Secretary Critchfleld, and he has ordered it printed as a Special Bulletin by the De- 

 partment of Agriculture. This will consequently be issued soon.— H. A, S.
