Due to its wide distribution and heavy damage, it has caused serious economic losses in fruit and vegetable production in China. This paper assembles research progresses in mor- phological characteristics, classification status, host ranges, geographical distribution, population dynamics, molecular ecology and biology of B. scutellata, and put forward the following research prospects as well.展开更多
