An experiment was conducted in Kitale, Kenya in 1987 to obtain information on pheromone traps and lures for a monitoring system for the maize stalk borer, Busseola fusca (Fuller). Several factors potentially affecting the catch of male B. fusca adults were evaluated. A trap's location in the field had the greatest impact on moth catch, with traps located near field edges catching more male B. fusca than traps located further within the field. Of the two trap types evaluated, net traps caught significantly (P < 0.01) more male B. fusca moths than water traps. The most moths were captured with lures containing the highest loading rate. In addition, the overall trend of our results suggests that loading rates greater than 9 mg, the highest rate tested in this study might result in even larger moth catches. The effect of the amount of time a lure remained in the field on the number of male B. fusca moths captured was examined using simple linear regression and a significant relationship was observed ... |
