tlius prevent them from attacking tlic trees, are suggested. To prevent 

 the worms from getting to the buds the painting of the trunks of the 

 trees with ''Eaupenleim," ^'Dendrolene," or some other sticky caterpil- 

 lar lime has i)royed quite effective. 



The mechanical devices which have been looked upon with favor are 

 collars of stiff', smooth paper pulled out in funnel shape at the bottom 

 and collars of cotton batting, a band of batting 4 or 5 in. wide being 

 bound at its bottom around the tree and the top then pulled over in 

 the shape of an inverted funnel. This has proved an effective barrier 

 against cutworms and is not readily matted down by rain. 



For killing climbing cutworms jarring them from the trees at night 

 on to sheets and digging them out of the ground during the day, 

 although tedious methods, have proved profitable. Poisoned baits of 

 fresh foliage sprayed with Paris green and a moistened mixture of bran 

 and Paris green were eagerly eaten by the cutworms, which died in a 

 few hours, in some cases 90 per cent being killed. In gardens it is 

 recommended that the advent of the cutworms be prevented by plow- 

 ing deep furrows around the patches to be protected, and that such 

 destructive measures as spraying with Paris green, hand picking, and 

 the use of poisonetl baits be employed. For grass lands and field 

 crops a short rotation of crops, leaving fields but a short time in sod, 

 is believed to be the l)est method of protection known at the present 

 time. 



Cut-worms in Kentucky, H. Garman {Kentucky Sta. Bid. 58, pp. 

 89-109, pi. 1, Jig. 1). — Owing to a marked outbreak of cutworms in Ken- 

 tucky in 1805 special attention was paid to these pests, and specimens 

 were sent to the station from various parts of the State. Descrijjti ve and 

 life-history notes are given for the traveling cutworm {Feltiaf/ladiaria), 

 dingy cutworms {F. jaculifera and F. subgothica), granulated cutworm 

 {F. annexa), greasy 'cutworm {Agrotis ypsilon), vatiegated cutworm 

 {Per idroma sancia), green cutworm (P. incirls), spotted cutworm {Noctua 

 hicarnea), W-marked cutworm {X. elandcstina), bristly cutworm {Mames- 

 tra renigera), glassy cutworm {Xylophasia devastatrix), and bronzed 

 cutworm {Xephelodes minians). 



Several species of cutworms were bred at the station for purposes 

 of accurate identification. As remedial treatment are recommended 

 burning of tracts suspected of harl)oring cutworms or known to do so, 

 inclosing newly set plants with paper or tin (cylinders, and the use of 

 poisoned bait, which is to be prei)ared by dipping bunches of clover 

 in Paris green water. Some of the worms in the laboratory investiga- 

 tion were found to be infested with bacteria and others with a fungus 

 disease, which proved to be quite readily communicable, and which it 

 is hoped may prove of advantage in destroying worms in the field. 



Examination of the stomachs of bluebirds killed in February showed 

 that on an average 30 per cent of the contents consisted of cutworms.
