Integration of Three Biocontrol Agents for the Control of the Cabbage Worm, Artogia (Pieris) rapae (L.).

Abstract: Laboratory and field experiments were conducted to evaluate three biocontrol agents for the control of the cabbage worm, Artogia (Pierix) rapae (L.) as new approaches of integrated pest management (IPM).Under laboratory conditions, larvae and pupae of A. rapae were highly susceptible to two nematode species; Heteromhabditis bacteriophora (TWF strain) and Steinernema carpocapsae (All strain). Dipel 2X (The commercial formulation of the bacteruim Bacillus thuringiensis var. krustaki) exhibited highly toxic effect against A. rapae larvae (93.3% mortality); while Biofly (the commercial formulation of the fungus Beauveria bassiana) was less pathogenic (39.2% mortality) and the nematodes alone gave mortality between 73.3 - 100 and 53.3 - 100 % among larvae and pupae, respectively. When both nematodes were combined with Dipel 2X, 100% larval mortality was achieved and when combined with Biofly, mortality ranged between 88.9-93.3%. Under field conditiotis, insect mortality 7 days after application was 76.1 and 74.1% for S. carpocapsae, TWF, after spraying two times. The combination between the nematodes (S. carpocapsae and TWF) and Dipel 2X or Biofly, respectively gave 87.5 and 76.1 % for S. carpocapsae. The corresponding values for TWF were 98.3 and 76.4 % when combined with the two pathogens, respectively. Dipel 2X and Biofly when used alone, 82.7, 17.9 % insect mortality was recorded for the two pathogens, respectively.
