The same paper gays that the Pea Bug can be effectually got rid of, by taking the seed when ripe and dry; put it in bottles and cork it up perfectly air-tight. The larvae, though not so minute as not to be seen by the naked eye, will die for want of air, just like any other living thing.
Professor J. P. Kirtland gives, in the Ohio Farmer, the results of some experiments made with chloroform, with a view of destroying the larvae of the pea bug. He says:
" The eggs of that insect are deposited in the pea while it is yet young and tender. About the period when the pods become dry, the young larvae are hatched, and commence depredating on the cotyledon of that vegetable. That is the moment to be improved for arresting the progress of the evil.
"The seeds should be shelled from the pods, and placed in a suitable bottle, closed vessel, or box. On them should be sprinkled a few drops of chloroform, which should be extensively shaken. This should then be corked, and every specimen of insect within it will probably be destroyed in twenty minutes' time; but, to render the process perfectly successful, it is well to continue the peas in their inclosure for twenty-four hours, or longer. Seed peas thus treated, will show, on examination, a mere speek at the point, occupied by the young worm. But the advantages of this process will be most observable when the plants from these seed peas make their growth next season. They will be far more vigorous and healthy than those starting from seeds which have been extensively excavated by that depredator. By this method we can annually preserve the seeds, and perpetuate the cultivation of the fine varieties of this vegetable, in this vicinity, without resorting to foreign importations".
Seed peas raised in the United States are found, on opening, more or less infested with this insect, and especially is this the case with the garden pea at the South. Another species of the same genus (Bruchus) attacks the kidney bean and the cow pea, and is still more destructive. The Pea Bug seldom attacks the germ, but the bean is all eaten except the outer coat. The insect found in the bean is much smaller than the Pea Bug, but several occupying one seed. Clover seed I believe is sometimes rendered worthless by an insect similar to these.
With the pea and bean bugs I have little trouble; when gathered and thoroughly dried, I put them in perfectly tight bottles, or earthen jags, according to the quantity I wish to save for seed. In these I put a teaspoonfnl of spirits of turpentine or a lamp of camphor, but I prefer the former, and cork them tightly. The name of the variety written on a card is fastened to the bottle by a piece of twine. When I wish to plant them, I find them on opening perfectly sound. The turpentine effluvia is fatal to the insect. If I wished to preserve a larger quantity, I should put them in camphene or turpentine casks, from which the contents had been recently drawn, and seal them tightly. This for seed. For the table, instead of the above mode, the beans are placed when dry in a brick oven, in shallow pans; after the bread is withdrawn, there is heat enough to kill the egg without injuring the quality of the beans.
Yes; the "allies," with the "bug," are quite as fatal to the pea as allies of another kind with the Turks, are to the Crimea - a "pea" of another sort; but which they, "the enemy," are equally ready to appropriate, as we are the less important vegetable. I'll file away this cure in the same pigeon-hole with the bark louse.
