Alternative Strategy
Bacillus thuringiensis (B.t.) is a bacterial insecticide (biopesticide). Subspecies of B.t. control certain types of pest insect effectively. Commercial products for control of lepidopteran defoliating insects are usually based on Bacillus thuringiensis subspecies kurstaki, or Bacillus thuringiensis subspecies aizawai (Van Driesche et al 2008). Using B. thuringiensis subspecies kurstaki is a suitable method for controlling Thyrinteina arnobia if predatory and parasitic insects are to be preseserved. B.t. is equally effective as insecticides (Pereira 2007). For the integrated management of Thyrinteina, its occurrence and population densities need to be monitored. Biopesticides based on B. thuringiensis are only effective when applied to larval stages of pest insects at appropriate times. B.t. can be combined with a chemical insecticide (Zanuncio et al 1992). But if applied in time B.t. is effective on its own.A combination of Beauveria bassiana (strain GHA) and Bacillus thuringiensis subspecies tenebrionis increased mortality of Colorodo beetle larvae (Coleoptera) synergistically (Wraight & Ramos 2005)
This approach of combining B.t. and Beauveria bassiana merits to be tested also on Costalimaita.
