SUCCESSFUL FARMING 



BROAD-BEAN WEEVIL 



(Laria rufimana). 1 

 Adult, or beetle, enlarged. 



other food plants are known, including a few garden crops and a number of 

 weeds. 



Treatment. Spray or dust arsenicals upon the leaves. Poison bran 

 mash may also be of value.

Beet Leaf Beetle, The Larger (Monoxia puncticollis, Say.). This leaf 

 beetle, known also locally as the alkali bug and 

 the French bug, resembles somewhat the elm- 

 leaf beetle. It causes considerable injury to the 

 sugar-beet in Colorado and nearby states. 



Treatment. Dust or spray foliage with ar- 

 senicals. 



The Beet Leaf Hopper (Eutettix tenella, 

 Baker) . The beet in the Western states is often 

 troubled with a condition known as "curly leaf," 

 caused by the above-named leaf hopper, a light 

 yellowish green species about one-eighth of an 

 inch long. 



Treatment. Spray the beets thoroughly with 

 a 40 per cent nicotine sulphate solution in 



water, diluted 1 part 

 to 600; or spray with 



5 per cent kerosene emulsion. Many hoppers 

 may be captured on a shield smeared with 

 tanglefoot or covered with sticky fly paper 

 if it is pushed up and down between the 

 rows. A wire or rod should be fastened in 

 front of the shield at the proper distance to 

 stir out the hoppers.

 Blister Beetles (Meloidce). At times a 

 number of crops are badly damaged by the 

 insects known as blister beetles or " old- 

 fashioned potato bugs." These beetles are 

 rather large, long-legged and are variously 

 colored, the usual colors being black,*gray or 

 striped with yellow and black. 



Treatment. Apply arsenate of lead or 



other arsenicals to the affected plants as a spray or dust. Several treat- 

 ments may be necessary if the beetles swarm on crops from other localities.

The Cabbage Looper (Autographa brassicce, Riley). The looper is a 

 light-green worm often referred to as a measuring worm because of its 

 looping movement when crawling. It feeds on the leaves of cabbage.
