Abstract: Harmonia axyridis, one of predatory insect species, plays a key role in the biological control of agroforestry pests. With the continuous increase of corn planting acreage and pest resistance to chemical insecticides, species and amount of insect pests in corn fields are rising quickly, which seriously influence yield and quality of corn production, furthermore have a negative impact on farmers’income. So, timely summary on researches of Harmonia axyridis can provide references for a comprehensive understanding its biological control function, support its field application and furthermore to guarantee the sustainable production of corn. In this review, the authors summarized domestic and abroad researches on biology and ecological characteristics of Harmonia axyridis, including life history, habits, flight and movement, field release, temporal dynamics and spatial distribution, reproduction and breeding, and predicted the new hot spots of researches in the future. Based on the latest advance of artificial feeding technique and the evaluation of practical control efficiency of Harmonia axyridis, we propose to release Harmonia axyridis to effectively control pests in corn fields, and points out that Harmonia axyridis has biocotrol potential, artificial feeding and field release of Harmonia axyridis could effectively prevent and control corn pests to guarantee a sustainable corn production.
