The objective of this study was to characterize horticultural farms in Cerro Punta, Highlands– Chiriqui; about socioeconomic and agri-environmental aspects, with emphasis on the pesticides used, Panama. About 31 farms were randomly selected and producers were surveyed. In addition, a random soil sampling was carried out in five locations, to proceed with the physical-chemical analysis and pesticide residues analysis, such as organophosphates, carbamates, pyrethroids and organochlorines. According to the results, 48% of those surveyed are between 41 and 55 years old, with education at the primary level in 39% of cases and 55% belong to farmers associations. The five main crops are potatoes, carrots, cabbage, lettuce and onion and 26% carry out animal husbandry. The production costs were variable, from less than USD 3500 to more than USD 14 000 per hectare per year; the yield ranged from...

El objetivo del presente estudio fue identificar larvas urticantes de Lepidoptera encontradas en parcelas con cultivos hortícolas en Cerro Punta, Chiriquí, Panamá y confirmar los posibles síntomas causados por erucismo y lepidopterismo. Se realizaron 16 muestreos aleatorios durante 14 meses y medio, en parcelas con cultivos, vegetación aledaña e infraestructuras. Se tomaron fotografías y se recolectaron muestras para su procesamiento en el laboratorio. Se consultó literatura especializada para la identificación. Se levantó una encuesta a 33 personas afectadas por erucismo o lepidopterismo. De acuerdo con los resultados, las larvas encontradas en los cultivos correspondieron a Leucanella hosmera (Schaus, 1941) (Saturniidae), Halysidota tessellaris (Smith, 1797) (Erebidae), Acharia stimulea (Clemens, 1860) (Limacodidae) y se encontró un espécimen adulto de Megalopyge operculari...
