There are 16 sections in this congress, including almost all the research field of entomology, such as “Agricultural and Forest Entomology”, “Genetics and evolutionary biology”, “Parasitology, Pathology and Immunity” and “Physiology and Biochemistry”. According to statistics, 945 experts from 65 countries have registered and attended the congress, and 460 oral presentation were given with 560 poster displayed during the entire congress.

Professor Xuexin Chen, Professor Fei Li, Associate Professor Min Shi, Postdoc Kang He, doctorial student Chunlin Yin and Xinhai Ye from the Institute of Insect Sciences have attended the congress.

Dr. Kang He grave the oral prestation of“Multiple miRNAs jointly regulate the biosynthesis of ecdysteroid in the holometabolous insects, Chilo suppressalis”. At the same time, Professor Fei Li and doctorial student Chunlin Yin and Xinhai Ye have displayed the latest research results of insect genomics in the manner of poster, respectively.

During the congress, Professor Xuexin Chen and Professor Fei Li had discussed and conducted in-depth exchanges with peers of entomology from Italy, France, Germany, the United States and Czech, which should contribute to the further strengthening and promoting of cooperation research.
