(t?>() JiVA-OlVV OF THE EnTOMOLOOLST OF THE 



were placed on still another field. The bran was first moistened 

 and thf'n Paris j^rcen added at the rate of one ponnd of Paris 

 green to fifty pounds of bi-an. Fourth, about nine o'clock in the 

 evening ol May 12 a number of rows which ran parallel with a 

 ditch were sprayed with kerosene emulsion, a stock solution of 

 kerosene emulsion dilnted with eight parts of water being used. 

 At the time (lie si)iiiyin.t;\vas done the little cutworms had climbed 

 to the tops of the onions and were busy feeding. Examination 

 with a lantern while spraying showed that the worms fell to the 

 ground as soon as struck with a particle of spray and to all ap- 

 pearances were injured to such an extent that they would soon 

 die. Early the next morning the surface of the ground where 

 the spray was applied was carefully examined. No dead cut- 

 worms could be found on the surface, nor were any dead ones to 

 be found buried in the loose surface soil. Cutworms taken from 

 the surface of the ground immediately after spraying and con- 

 fined became active and, apparently, were not permanently 

 injured. 



Results. 



The results of the tests as a whole were as follows: Where the 

 onions were sprayed with Paris green added to the resin-lime 

 mixture no dead cutworms were to be found. A few sickly speci- 

 mens were found liiddcn in tlie loose soil. The onions were so 

 small that only a very small poition of the spray could be made to 

 adhere to them. No dead cutworms could be found around or 

 under the poisoned grass baits. The grass remained fresh only 

 one night. A large number of dead cutworms were found around 

 the poisoned bran baits, not only under but hidden in the loose 

 soil around the baits and on the surface. 



All these remedies were known and had been tested, but it 

 was deemed advisable to test them on the onion fields where the 

 owners of the fields could see the practical results, as the}' were 

 the most iiractical remedies that had been recommended, except 

 hand picking, which was well practiced. No further tests were 

 made at the time.
