Figures & Tables

Figure 1:

Mortality of Bemisia tabaci Middle East-Asia Minor 1 (MEAM1) nymphs (%) on snap bean leaves caused by the ten treatments at 3 days post-inoculation in the first virulence experiment. Treatments: Hb = Heterorhabditis bacteriophora (VS strain), Hi = H. indica (HOMl strain), Hg = H. georgiana (Kesha strain), Hf = H. floridensis (K22 strain), Sf = Steinernema feltiae (SN strain), Sc = S. carpocapsae (All strain), Sri = S. riobrave (355 strain), Sg = S. glaseri (VS strain), Sra = S. rarum (17C&E strain), CK = Water control. Different letters above bars indicate statistical significance (P < 0.05) among the treatments.

Mortality of Bemisia tabaci Middle East-Asia Minor 1 (MEAM1) nymphs (%) caused by the five treatments at 3 days post-inoculation in the second virulence experiment. Treatments: Hb = Heterorhabditis bacteriophora (VS strain), Hf = H. floridensis (K22 strain), Sc = Steinernema carpocapsae (All strain), Sra = S. rarum (17C&E strain), CK = Water control.

Mortality of Bemisia tabaci Middle East-Asia Minor 1 (MEAM1) nymphs (%) caused by the five treatments at 7 days post-inoculation in the second virulence experiment.
