The first experiment (against
thrips complex) indicated that A. swirskii, reared on ornamental
pepper plants, showed significant suppression of the population
of the thrips complex (excluding eggs, because of the difficulty in
counting eggs in the greenhouse by magnifier) infesting the green
bean plants (t= 7.87; df=8;P= 0.001). The number of thrips complex in the treatments was only 13.4 per plant (based on total
leaves) compared to 235.4 per plants in the control.
