ALTERNATE HOST PLANTS OF THE PINK BOLLWORM, PECTINOPHORA GOSSYPIELLA (SAUND.), IN PUERTO RICO

A knowledge of the importance that alternate host plants play in the perpetuation of the pink bollworm, PecUnophora gossypiella (Saund.), from one cotton crop to the next is valuable in formulating methods for its control. Heretofore this problem has been little studied in Puerto Rico. Puerto Rico is comparatively rich in Malvaceae, the only family of plants that has been found to include species attacked by this pest, 19 genera and 59 species having been recorded. Other than cotton, however, only 5 genera and 9 species of food plants of the pink bollworm are found on the Island. The importance of each of these food plants in maintaining the pink bollworm in the absence of cultivated cotton is briefly discussed in the following notes.
