336 THE PEOPLE'S FARM AND STOCK CYCLOPEDIA. 



properly caterpillars, mine the cabbage leaves quite disastrously r 

 and which gray moths, with a white stripe along the back, are 

 quite too small to produce alarm, and yet are the parents of the 

 same green larvae. But I will only say that I have never been 

 troubled with them, nor have I seen much of their work. If 

 they are annoying, it would be well to try plaster with a little 

 turpentine mixed in, whale-oil soap solution, or lime ; nor should 

 I fear to experiment with a little powdered white hellebore. 

 All of the leaf-rollers, several of which are quite destructive 

 to the apple foliage, are quickly destroyed by use of the arse- 

 nites; but it is unsafe to use these on the cabbages. Pyrethrum, 

 which, as we shall show, is a most satisfactory specific against 

 the cabbage caterpillar, would doubtless also destroy the insect 

 just described. 



Striped Flea-Beetle. Hattica striolata, Fabr. Family, 

 Chrysomelidce. Order, Colcojitcra. There is a flen-bcetle, too 

 (Haliica striolata, Fabr.), which I have found to puncture the 

 leaves of cabbages, and is thus quite destructive to young plants. 

 It also works on radishes, turnips, etc. 



NATURAL HISTORY. This beetle is of a shining black color, 

 with two waving lines of buff along the back, one on 

 each side, is very small, less than one-tenth of an inch 

 in length, but is so active, briskly leaping away at the 

 least disturbance, that, though so small, it can hardly 

 escape notice. (Fig. 15.) These beetles often fairly Fio 15 

 swarm on young plants, and at such times do considerable damage. 



REMEDIES. In England, where a nearly related beetle has 

 long given annoyance by attacking cruciferous plants, lime, soot, 

 and even ashes, are recommended as securing the plants against 

 the ravages of these pests. I have tried these remedies, but 

 without perfect success. Still I think they are to be recom- 

 mended. Quick lime will do even more to protect the plants. 

 Any thing which promotes vigor of growth is, of course, desir- 

 able, for vigorous plants are far less liable to suffer destruction. 



By sweeping a fine gauze net over the plants, large numbers 

 of the insects may be caught and destroyed.
