The legume family (Fabaceae) is the third largest family of flowering plants worldwide and often damaged by stink bugs, particularly Riptortus clavatus Thunberg (Heteroptera: Alydidae). This insect selectively feeds and oviposits on these plants, resulting in >50% of damage to soybeans harvested in autumn. The most common control methods for this insect are periodic application of chemical pesticides, pheromone traps, and bait crops, but still they encounters residual problem, insect resistance or low control efficacy. The current management system needs alternative control methods, which possibly combined with the present methods. Some entomopathogenic fungi have high virulence against the nymphs and adults of R. clavatus in a favorable conditions, reaching ∼80% mortality with mycosis in 3∼5 days. The genera of Beauveria and Metarhizium are possible control agents for effective and safe management of the serious pest. Fungal infection in R. clavatus was observed using an egfp-expressing fungal transformant. Thermotolerant entomopathogenic fungal conidia can be produced in cereal substrates, which enables conidia to be stable for long times. Our considerations need to be given to the combinations with other control methods, such as chemical pesticides or pheromone trap.
