| Resumen: ||The use and management of insecticides to control whiteflies (Bemisia tabaci) and other pests of tomato and bell pepper [Capsicum sp.] were studied in Alajuela, Cartago, Heredia, Guanacaste and San José provinces of Costa Rica. Eighty farmers were interviewed between March 1996 and February 1998. All farmers used pesticides to control the pest. The preferred pesticides were pyrethroids (100%), organophosphates (87.5%), chloronicotinyls (77.5%), nereistoxins (45.0%), carbamates (36.2%), cyclodienes (26.2%), biological (22.5%), and avermectins (21.2%). During the dry season, the producers preferred a combination of pesticides from 6 of the aforementioned pesticide families, while in the rainy season, they used products from 4 of the pesticide families. None of the interviewed farmers used complete protection equipment when applying pesticides because such was costly and uncomfortable. Most of the producers used the recommended rate of the product per unit of volume. Fifty-three percent of the farmers interviewed mixed up products without technical criteria, overdosing when mixing up the products with different commercial names but had the same active ingredient. This practice may favour the appearance of pest resistance since it subjects the pests to higher selection pressure|
