242 THE MONTHLY BULLETIN. 



The method of preparation as recommended by Geo. A. Dean, Ento- 

 mologist of the Kansas State Agricultural College and Experiment 

 Station, is as follows : 



"Mix the bran and Paris green thoronshly in a wash tnb. while dry. Squeeze 

 the juice of the oranses or lemons into the water, and chop the remaining- pulp 

 and the peel to fine bits and add them to the water. Dissolve the syrup in the 

 water and wet the bran and pour in with the mixture, stirring at the same 

 time, so as to dampen the mash thoroughly." 



This should be scattered about while moist where grasshoppers occur. 



It is claimed that the addition of lemons is a great advantage in that 

 the mixture is rendered more palatable to the hoppers. In the case 

 of the work being done by the American Beet Sugar Company there 

 seemed no doubt of this fact, for the poisoned bran, even when dry, 

 was eaten ravenously. By placing poison about the fields wherever 

 hoppers were entering from the pasture lands complete control of the 

 situation seemed to result. The ground was covered with dead hoppers 

 in the vicinity of the poison, and here and there where there happened 

 to be a slight depression or a little gully they were piled one on top of 

 another. 



The great success attained in the use of this formula prompts us to 

 recommend it to any who may be troubled with the grasshopper pest 

 this season. — Geo. P. Welclon. 



Hop Aphis. 



To the hop growers the hop aphis is a well known insect. It is pale 

 yellowish-green in color. According to W. B. Parker^ the hop aphis 

 injures the crop in two ways: by sucking out the juices of the plant 

 and by furnishing a medium for the black smut fungus to grow in. 

 The cone scales covered with the mildew secreted by the hop aphis are 

 soon covered M'ith the black smut fungus, injuring their commercial 

 value. The infestation of the hop aphis retards the plant's growth. 

 The formula consisting of blackleaf 40, 1 to 2000 of water with flour 

 paste 4 gallons to each 100 gallons of the spray is effective. It must be 

 remembered that spraying in spring for the hop aphis the aphids must 

 be hit by the spray in order that they may be destroyed. 



The Red Spider on Hops. 



The hop red spider is a general feeder on many of our field crops. 

 It is a small reddish or greenish-yellow mite and feeds principally on 

 the lower sides of the leaves, covering them with a fine web. The 

 yellow spots made by the mites in the leaves soon become very numerous 

 after the leaves are infested and later the leaves turn yellow and fall. 

 The spray recommended by W. B. Parker of the U. S. Bureau of Ento- 

 mology, consists of flour paste 8 gallons to 100 gallons of water. The 

 flour paste is made by using a cheap grade of wheat flour with cold 

 water making a thin batter ; use one pound of flour to one gallon water, 

 cook until a paste forms ; use in the above proportions.
