| Abstract: | As the scarab larvae (Scarabacidae) in peanut field are controlled by seed dressing with bacterial agent No.8 (Bacillus thuringiensis var.Kurstaki),its economic injury level for simple and about one-third middle size species populations are 1672 and 6498 larva survivals per mu respectively.Thus,the action thresholds of eggs in hatching stage can be determined,based on the natural hatching rate and the larvae survival from egg stage to peanut harvest. |
