Description
Summary:Wild Mediterranean fruit flies Ceratitis capitata (Wied.) were exposed to 6 different combinations of Jackson trap designs and colors, in a coffee plantation near Antigua, Guatemala. Their pattern of arrival, landing, and capture or escape during different hours of the day and trap environments were observed. Maximum catch was recorded during rain-free afternoons, in tall and dense coffee vegetation. The standard Jackson trap caught significantly more flies than the open bottom Jackson trap, and yellow traps were significantly more effective than white traps. An unknown number of flies were attracted to the surroundings of traps but did not approach them during the allocated 30 min. observation periods. Of the flies approaching a trap, 18.6% were caught initially, and another 7.8% were caught during the observation period as a result of agonistic interactions between males accumulating inside the standard Jackson traps. The large presence of males remaining inside the traps suggests that the daily percentage of capture is much higher than the 26.4% documented during the short observation periods. Male aggregation and territoriality inside and around the traps, as well the pattern of male-female attraction, indicate that the parapheromone trimedlure has an effect similar to the medfly male pheromone. /// Moscas del Mediterráneo silvestres (Ceratitis capitata Wied.) fueron expuestas a 6 diferentes combinaciones de diseño y color de trampas Jackson en una plantación de café en las cercanias de la ciudad de Antigua, Guatemala. Se estudiaron los patrones de arribo, aterrizaje y captura o escape durante diversas horas del dia y diseño de trampa. Máxima captura se obtuvo durante tardes sin lluvia bajo condiciones de vegetación densa de café. La trampa Jackson estandar capturó más moscas que la Jackson sin base (differencia significativa) y las trampas amarillas capturaron más moscas que las blancas (diferencia significativa). Un número desconocido de moscas fue atraido a la cercanía de las trampas pero no se dirigió directamente a las mismas durante los periodos de observación (30 min). De las moscas que se dirigieron a las trampas, 18.6% fueron capturadas inmediatamente y otro 7.8% fue capturado como resultado de interacciones agresivas entre machos que se iban agregando dentro de la trampa. El gran número de machos que permanece dentro de la trampa sugiere que el porcentaje diario de captura es mucho mayor al 26.4% determinado durante los cortos períodos de obs
