BEAN. 
or three weeks, and there is a succession of broods, so that the insect 
may be found in all its stages throughout the summer. 
The grubs hold on to the stems so tightly by the ends of their tails 
that it is a hard matter to pick them off; but if the Asparagus is 
syringed with warm water (or cold may be used), and the plants then 
smartly shaken, many of the grubs will fall to the ground. A good 
sprinkling of soot or of quick-lime, thrown down on them immediately, 
will prevent them, or most of them, returning to the plants. Dipping 
the shoots in a mixture of a quarter of a pound of flour of sulphur, a 
quarter of a pound of soot, and half a pound of soft-soap, all well 
stirred together in a pail of water, has been found useful. 
BEAN. 
Bean Aphis; Black Dolphin; Collier. Aphis rumicis, Fab. 
Bean Aphis. 1, Bean-shoot with Aphides ; 2, male, magnified ; 3, natural size ; 
4, wingless female, magnified. 
The only note of the presence of Aphides, or Collier, occurring on 
Beans to a destructive extent during the summer, was forwarded by 
Mr. Harley Kough, of Church Stretton, who mentioned, on July 8th, 
that the Beans in his garden were greatly blighted. No better remedy 
appears to be known at present than cutting off as much of the top of 
the Bean plant as is infested directly the Colliers are seen upon it, 
taking care, at the same time, that the pieces which are cut off shall 
be removed and destroyed, so that the Colliers shall not be able to get 
back again from them to the growing Bean crop. 
At Detling, Maidstone, it is noted by Mr. R. Cooke that attack of 
Bean Aphis was kept fairly in check by picking off and burning the 
tips of the shoots affected ; and at Park Farm, near Kingsnortli, Kent, 
the field crops were generally clean.
