 chief offenders along this line.

 i-ecoinniendations regarding methods of treatment. 



C. E. Sanborn discusses the melon aphis and other related insects, with notes 

 on remedies. For coml)atiug the melon aphis considerable I'eliance may be 

 placed in the use of rape as a trap crop. Other methods are suggested,

Western slope fruit investigation, 1906. Report of the field entomologist, 

 K. V. Taylor {Colorado Sta. liiil. 119. pp. Id). — During the season of I'.XXi 

 attention was directed chiefly to methods of controlling the codling moth. 

 Little variation was observed in the habit of the moth In the different orchards. 

 It appears that about (50 per cent of the first brood enter the apples at the calyx. 

 'I'he second application of the insecticide must be niad<> early enough to coat 

 the surface of the small apple before the larva^ attem])t to enter through the 

 side of the fruit. There are but 2 generatiims of the insect, and it is believed 

 that li sin-ayings should be effective against the first brood, rendm-ing the second 

 brood of little importance. 



The first api»lication of arsenicals was made about the middle of .May. the 

 second about the first of .Tune. If desirai>le, other applications may be given 

 at the first of July, the middle of .Tuly. and the first of .\ugust. 



Notes are also given on tiie i)each-twig borer, apple aphis, woolly aphis, and
