Insect-Plant Interactions and Control

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.
