The ])resence of this insect in the ^Tox'e can always be detected 1)\' the ])eculiar shaped in which the insect spends the winter. The cone-sha])e(l cases are made of little sticks and rubbish fastened to*;c'ther by silken threads. The baj^^ worms cat the leaves to some extent and sometimes scar the fruit, as illustrated in I'vj^. 27, but fortunately they are not usu- ally abundant enoui;h to be worthy of notice. In case it should be necessary t,o resv)rt to measures of control, they may be poisoned by the same arsenicals that are used for other biting insects. 51. Ants.—In Southern Florida the leaf-cuttini( ants and in Louisiana the recently introduced Ari^entine ant, does damaj^e to orange trees, the former by cutting and carrying away the leaves. These ants can l)e effectively controlled by trailing them to their nests and treat- ing the nests with a solution of ])()tassium cyanide. A hole is made in the middle of the nest and into it is ])()ured a few ounces of the solution, which consists of 1 ounce of i)otassium cyanide to 1 ([uart of water. The ftuues given off will i)enetrate the hill and kill all the ants ])resent. If the nest is near enough to the tree for the li([ui(l to reach the roots it must be used cautioush'. Potassium c\-anide is one of th(> most T)owerful ])oisons and must be handled with care. In case the nests cannot l)e found, the insects ma>' be kept from the trees by banding them wit
