. Agricultural news. Agriculture -- West Indies; Plant diseases -- West Indies. 184 THE AGRICULTURAL NEWS. September INSECT NOTES. The Woolly Pyrol Moth. A largo aiva of green ( is grown annually in Barbados and has this year, as in some jn-evious years, suffered heavily from the attacks of insects. Whole fields have been destroyed by the caterjiil- lars of the Woolly Pyrol Jloth and njiparentlv little or 1,0 effort has been made to cheek this destruction. There is a current belief that tlie eating up of these green dressings is of no importance as the vegetable matter reaches the soil after jiassing through the bodies of the caterpillars, and thus is not really lost to the soil. This would be true if the whoh' (if tile niateiial of the j)lant reached the soil through the catirpillar, and if as much vt'getable matter were produced by the plant whethei- or no the caterpillars ate its foliage. Unfortunately neitlier of these sujipo- sitions is correct. 1'his moth lives all the year round on a variety of |)lants and does not increase to any great extent until its food-plants (woolly pyrol and other green dressings) are jihinted over large areas. The abun- dance of its food suj)ply then leads to ra]iid increase and the green dressings are gradually destroyed. As was pointed out in the Cth. Lecture to Plantei's in Barbados, in October 1901, this state of things need never occur. If at tlie commencement of the titfacl; the plants were sjirayed witli Paris green or other arsenical ]ioison, or if they were dusted with a mixture of lime and Paris green, the first batch of caterpillars would be destroyed and the attack checked a/ iln outset. The matter is in the hands of the jilanter, and if ln> followed tJiis course it is pro'jable that his crop would attain its full growth and he would not grow a stunted cro]} lo be cliietly consumed in feeding hordes of caterpillars, which later become moths and tlv away.
