CABBAGE APniS. INJURIOUSNESS. LIVES IN CLUSTERS. 
never suffer from this insect. By raising a brood of chickens 
annually iu our gardens, and having the toad domesticated there, 
we can readily prevent these striped ilea-boctles from becoming 
multiplied and injurious. And if these animals cannot be pro¬ 
cured, and these beetles get to be numerous and detrimental, we 
can usually protect the plants from them by dusting them with 
ashes. Thus we have remedies against this insect which are so 
easily obtained and applied, and are so efficacious, that we can 
scarcely desire anything further in the premises. 
Cabbage aphis, Aphis Brassicce, Linn. (Uomoptera. Aphides.) 
•On the loaves of cabbage and ruta baga through tho soason, sucking their juices; dull 
greonish plant lice, solitary or in dusters, the winged ones varied with black. 
One of the insects most common upon the cabbage and from 
which it suffers much injury is the plant-louse. From July to 
the close of the season it may be found at all times upon some of 
the leaves of almost every plant, either wandering about solitary, 
or stationary and closely crowded together in clusters covering 
portions of the surface. It inhabits for the most part the upper 
sides of the inner leaves and the under sides of the outer ones. 
It is in the former case that it is most pernicious, by sucking the 
juices from and weakening this part, whereby it heads tardily and 
imperfectly, or, if the lice are numerous, no head is formed and 
the plant is worthless. J. L. Edgerton, of Waverly, N. Y., states 
(Country Gentleman, July, 1857, p. 80), that his patch of cabbages 
the year before, comprising 350 large, thrifty plants, were attacked 
by lice just as they were beginning to head, and in three weeks 
every plant was covered by these vermin, and he lost tho whole, 
neither ashes or salt having any effect upon them. 
Each cluster of these plant-lice is composed of wingless indivi¬ 
duals of different sizes, all of which, except the smallest ones, are 
coated over with a gray meal-like powder. And a few very small 
black lice, having wings, are common!}' standing here and there 
among and around those mealy wingless ones. And in almost 
every colony there may be noticed one or more bright yellow 
maggots. These are tho lame of ono or moro species of flics 
pertaining to the genus Syrjpkus, which feed upon and destroy the 
plant-lice. Lady-bugs and other destroyers also abound in their 
vicinity. And we frequently see places upon the leaves where the 
mealy powder and the white cast skins show that a colony of these
