Distribution and interaction of the suitable areas of Beauveria bassiana and Bactrocera dorsalis (Hendel)

Climate is a key factor affecting the potential distribution of insects, and host another important constraint for pests. To elucidate changes in Beauveria bassiana under climate change scenarios, this paper used data two different greenhouse gas (GHG) emission scenarios (RCP2.6, RCP8.5) to predict B. its typical host, Bactrocera dorsalis (Hendel), based on MaxEnt model. Then, (Hendel) was compared, their suitable growth area’s expansion trend GHG were mastered. The results study show that area will increase by 2,050 RCP8.5 scenario, mainly central Europe southwestern Asia, with an increased 3.28 × 10 5 km 2 . However, scenario RCP2.6, decreased 2.0 , North America. This provide theoretical basis control
