In the woodlands the gipsy moth multiplies unhindered.
It will be seen then, that unless the moth there is kept in check — and poultry is the only means in sight, the Bureau having nothing to offer but parasites and elimination of favorable food plants, such as oak — with the young capable of being blown for miles, there will be a constant reinfestation of cleared areas from this cause alone. This alone explains wh3' "it is inevitable that new colonies will be found from time to time outside th...e region now known to be invested,.." Thus in Dep. Agr. Bulletin No.
273, p. 18 it is estimated that the wind blows 210 million small larva annuall}^ into the ocean, and the number is probably much greater. It also emphasizes the necessit}^ of keeping this moth confined to New England territory if rapid and general spread over the United States is to be prevented." In Year-book Separate No. 704, p. 14, the U. S. Entomol- gist says: "On the whole, the work [of importing parasites of the gipsy- and brown-tail moth] has been very successful, and has helped in bringing about infinitelj'- better conditions in New England so far as these pests are concerned, and while it is prac- ticall}' certain that both the gipsy moth and brown-tail moth will (29) gfradually spread westward,- it is equally sure that the imported natural enemies will go with them, and that none of the long continued disastrous outbreaks which we saw in Massachusetts in the years prior to 1905 will occur further west."
