Abstract
The present study was carried out to test the biocontrol potential of symbiotic bacteria, Photorhabdus and Xenorhabdus against the shoot and fruit borer, Helicoverpa armigera in solanaceous vegetable crops grown under greenhouse conditions. A total of ten treatments were designed with symbiotic bacteria of entomopathogenic nematodes for testing their biocontrol potential by using Bacillus thuringiensis as a reference strain. The results had shown significantly higher biocontrol efficiency in the treatment T9 (H. armigera + Consortia) with 85-90% biocontrol efficiency in all the vegetable crops followed by the treatment T7 received Bacillus thuringiensis. Among the treatments received individual strains of entomopathogenic bacteria, T3 and T2 which received EPB3 and EPB1 with 75-80% biocontrol potential and are at par with each other. Other treatment received individual strains had shown more than 50% of biocontrol efficiency in vegetable crops grown in seedling trays under greenhouse conditions. Further these entomopathogenic bacteria can be tested for their effectivity under field trails and can be developed as bio-pesticide formulations either in the form of individual application or in integrated pest management for plant protection practices.
