BLACK FLY or BEAN FLY (Aphis rumicis), also called Collier and Black Dolphin. This Fly (see Fig. 254) is found on many herbaceous plants. It is very injurious to Beans; hence, immediate means of destruction must be employed directly the insect appears. Its extermination is an extremely difficult matter; but the following remedies are very effectual:
Tobacco Water. This, made and applied as recommended for [Aphides] (which see) is a good remedy; but it is rendered more certain by the employment of soapsuds, instead of clear water, in its manufacture.
