Report of the entomological section, C. P. Gillette {Colorado 

 Sta. Rjpt. 1899,2)]). 37-1^,1). — Observations made upon the codling moth 

 indicate that the insect is completely two-brooded, with no evidence 

 of a third brood. Good results were obtained in lighting it Iw banding 

 the trees. Kerosene emulsion was found to be practically valueless 

 against the codling moth. 



In making a stud}^ of the grasshoppers of the State it was found that 

 the 2 species most concerned in injuries to cultivated crops were 

 Mela7i02)lushivittatus and 3f. differentially. Not a single specimen of 

 the Rocky Mountain locust has been seen in the State for the past 9 

 years. The beet army worm {Lajjliygnia jiawhnaculata) caused severe 

 losses to the sugar-beet industry, 200 or 300 acres of beets being com- 

 pletely ruined by the attacks of this insect in the caterpillar stage. 

 Field experiments demonstrated that the ordinary arsenical poisons 

 are quite effective against it. The ash borer [Podosesia syringce) is 

 reported as rapidly increasing in numbers and as having killed many 

 ash trees. Experiments conducted with arsenical mixtures indicate 

 that Green Arsenoid and Pink Arsenoid are rather effective, while 

 White Arsenoid was too injurious to the foliage. 



Experiments have been conducted in the apiary for the purpose of 

 determining the best form of foundation for comb honey and the best 

 method of using the foundation in a section.

 ber, 1896, the author has made oljservations on a new beet aphis {Pem- 

 phigus hetce) which was found, upon investigation, pretty generally 

 distributed in the beet fields of the State.
