The following table gives some idea of the extent of the changes inthe varieties of cane cultivated which the liability of the Bourbon caneto attacks of rind and root fungus has occasioned :— 189719021907191219171918 (about) 6004,10033,66518,25067,68069,475 *Mixed in part with other varieties. The sugar planters during the 21 years under review have had diffi-culties other than droughts and fungoid diseases to contend with. Insectpests have been rife and have done great injury to their crops. Duringthe whole of the period the smaller moth-borer (Diatraea Saccharalis F.)has always been in evidence and has greatly reduced the yield of thesugar estates. Its inconspicuous nature, however, has apparently preventedthe majority of sugar estate managers and especially their field-assistantsfrom realizing what a dangerous pest it is and the immensity of the lossesit occasions. In 1899 a new sugar-cane pest was reported as occurring oncertain of the sugar plantations at Nickerie, Surinam. In thecourse of a few years it spread to British Guiana and from theforests behind the empoldered areas to the fields of sugar-caneand was then named the great moth-borer (Castnia liens.
