Research shows the effectiveness of a native Beauveria bassiana strain in controlling tarnished plant bug, suggesting a safer alternative to chemical pesticides.
Previous works reported that Beauveria bassiana (Balsamo) isolates from tarnished plant bug, TPB, Lygus lineolaris Palisot de Beauvois, (Hemiptera: Miridae) have shown a great potential to be used as a microbial control for TPB, particularly the NI8 strain, isolated from TPB from the Mississippi Delta. The Mississippi Delta native strain NI8 has been studied for more than ten years. Results from those studies demonstrated that NI8 strain has better characteristics of pathogenicity based on LC50 values, in vitro conidia production, temperature growth optima, tolerance to solar radiation, and production of beauvericin than the commercially available strain, GHA. The NI8 strain may offer an alternative to chemical pesticides protecting natural enemies without leading to secondary pests.
