126 SPRAYING CROPS 



broad, yellow, wavy stripe on each wing-cover It 

 feeds upon the surface of the leaf, gnawing out little 

 pits. The females deposit minute whitish eggs upon 

 the roots of cruciferous plants, such as radish, cabbage, 

 turnip, etc, and the larvae feed upon these roots, 

 sometimes doing serious damage. The full-grown 

 larva is about l /4 inch long, with a yellowish-white 

 body, and brown head. 



Remedies Spray the plants with a strong tobacco 

 decoction, or dust on powdered tobacco. 



In the southern states the HARLEQUIN CABBAGE- 

 BUG is a very troublesome pest. It feeds upon a 

 variety of cruciferous plants, such as cabbage, radish, 

 mustard, and turnip; and passes the winter in the 

 adult state. Early in spring eggs are deposited upon 

 mustard or radish plants, upon which the resulting 

 bugs develop. The second brood attacks the cabbage 

 and the insects continue to develop upon this crop until 

 autumn. According to Mr Howard Evarts Weed, 

 "there is but one efficient remedy for this insect, which 

 is, to destroy the brood which lives over winter, when 

 they congregate upon the mustard or radish plants. 

 Here they may be destroyed very easily by the applica- 

 tion of kerosene (not emulsified) by means of a hand 

 force-pump or common watering bucket. If the 

 insects are thus destroyed early in the- season, it will 

 almost wholly prevent injury later. The insects fly 

 but little, and are thus not apt to come from a neigh- 

 boring field." Those bugs or eggs which may be 

 seen on cabbage should be picked off and destroyed.
