Abstract:

In order to clarify the insect species and the dominant population dynamics in southwest Shandong, the automatic forecast lamps were set up in Mianfang and Shenzhuang of Zoucheng from May to September, 2019. The trapped insects were identified and the population dynamics of dominant insect species were analyzed. The results revealed that there were 53744 insects in total, which belonged to 56 species, 19 families, and 6 orders. The occurrence period was nearly 180 d, the full occurrence was from mid-June to late August, and the population dynamics of dominant species were analyzed. The investigation of insect species and the analysis of dominant population dynamics will benefit the understanding of the occurrence of insect spests in southwest Shandong and provide references for local agricultural production.

Key words: population dynamics, automatic forecast lamp, the peak of occurrence, prediction and forecast
