Field trapping of tomato moth, Tuta absoluta with pheromone traps

Field evaluations demonstrate that the addition of the minor pheromone component (3E,8Z)-tetradecadien-1-yl acetate to the major component (3E,8Z,11Z)-tetradecatrien-1-yl acetate does not significantly increase the trap catches of Tuta absoluta males in the field. The triene acetate itself is highly attractive, catching about 869 ± 255 males per trap in three consecutive nights. The addition of two isomers of the minor component (3E,8Z)-tetradecadien-1-yl acetate, (3E,11Z)-tetradecadienyl-yl acetate and (8Z, 11Z)-tetradecadien-1-yl acetate, to the major component (3E,8Z,11Z)- tetradecatrien-1-yl acetate also did not significantly alter the number of the males caught in the traps.
