The amount of the six-component blend loaded onto red rubber septa significantly affected the number of T. atristriga captured (Treatment, F3,16 = 4.7, P < 0.01) (Figure ). Increasing the dose from 0.1 to l mg resulted in a significant increase in the number of males caught (P<0.0001). Furthermore, increasing the dose to 10 mg resulted in a significant reduction in the number of males caught, compared with the 1-mg dose (Figure ).
