【Objective】 Shenzhou peach is the characteristic product of Hengshui City, but in recent years, due to the excessive use of chemical pesticides in peach planting area, not only destroyed the soil structure, but also made some pests gradually develop strong resistance to drugs, which brought serious threat to the quality of peach products. Therefore, targeted investigation was carried out. In order to effectively carry out biological control and achieve good control effect. 【Methods】The species and quantity of insects in Shenzhou peach orchard were investigated by the combination of net trapping and light trapping for 8 months. 【Results】 The results showed that by August 2022, a total of 98 198 insects of 153 species of pests and natural enemies in 8 orders and 53 families were collected. There were 124 species of pests accounting for 79.89% and 29 species of natural enemiesaccounting for 20.11%.The investigation found that there were fewer insects in peach orchard from January to March. Insects began appearing in April with 73 collected.482 insects were collected in May.24 048 insects were caught in June with numbers rising. In July, the number of insects reached the peak of 68 444, among which the number of Anomalacorpulenta was the largest. The species and number of insects gradually decrease after August. 【Conclusion】 It is obvious that temperature, humidity and insect number are positively correlated, and insect number increases with the increase of temperature and humidity.
