INFESTING GARDEN VEGETABLES. 



THE CABBAGE. 



AFFECTING THE LEAVES. 



Eating holes in the outer leaves late in autumn; a small, cylindrical, 

 pale green worm, wriggling briskly when disturbed, and letting itself 

 down by a thread. 



The Cabbage Moth. Cerostoma Brassicella. 



One of the most important culinary vegetables which we culti- 

 vate, the cabbage, is in Europe subject to the attacks of quite a 

 number of caterpillars and moths, some of which prey voraciously 

 upon it. In our own country this vegetable probably has as 

 many of these enemies as abroad; but so little attention has been 

 bestowed upon our noxious insects, that only two of these have as 

 yet been publicly noticed; the cut worm, which is everywhere 

 such a grievous pest, and the caterpillar of our white butterfly, 

 which, however, subsisting upon mustard, turnip, and most other 

 plants of the extensive orchjr Crucifera, seldom invades cabbages 

 in such numbers as to injure them. But I come to speak of 

 another worm, a moth, which makes greater havoc upon the 

 leaves of the cabbage than any insect which has yet been noticed 

 at home or abroad. And although it has not yet been observed 

 within the confines of our own State I entertain no doubt that it 

 exists here, and that it will at times become multiplied in par- 

 ticular localities, to the same extent that it has been in one of 

 our sister States the past season. 



In the neighboihood of Ottawa, Illinois, in October last, I ob- 

 served the cabbage leaves in the gardens perforated with nume- 

 rous holes of variable size and irregular form, by a small green 

 worm. Some gardens were so much infested that all the outer
