Fip. 40. — A, beetle; B, pupa; C, larva; D, a pod that has been eaten into. 
All a little enlarged. 
Remedies — On account of beans being very susceptible 
to injury from the application of arsenites, it is rather diffi- 
cult to treat this insect with satisfactory results. If the ar- 
senites are used, lime should be freely added. I have had 
best success by using kerosene emulsion of double strength 
(in which the kerosene is one-eigth of the mixture), spray- 
ing it on the underside of the leaves for the destruction of 
the eggs and newly hatched grubs.
