Abstract
The introduction, spread and present status of the pink bollworm, Pectinophora gossypiella Saunders, in Porto Rico are described. In order to understand the somewhat unusual conditions under which the insect is working in the Island the essential climatic and topographic features and the development of Sea Island cotton growing in Porto Rico are briefly outlined. Attempts at control are discussed together with the relation of alternate host plants as a factor in carry-over of the insect from one crop to another.Downloads
