The second cage experiments (againstB. tabaci) showed that A. swirskii reared on ornamental pepper plants significantly regulated the population of B. tabaciinfesting the green bean plants (t= 4.05; df=8;P= 0.0067). The mean number of B. tabacimotile stages (excluding eggs) was 2.75 per plant (based on all leaves) in the treatments compared to 379 per plant in the control (Fig. 3). Also, A. swirskii produced 6.25–53.4 motiles (excluding eggs) per plant in the treatments.
