Last Updated: 2024/11/06, The occurrence rule of Robinia pseudoacacia seed wasps is as follows: two generations a year, the second generation larvae overwinter in the seeds, the overwintering generation larvae begin to pupate in the first and middle of May, adults appear and lay eggs in the middle and late days. The second generation larvae appeared from late May to early June, the first generation larvae began to pupate in mid-June, the first generation adults appeared from late June to early July, and the second generation larvae appeared from late June to mid-July and overwintered in the seeds. The occurrence time of each generation varies due to climatic conditions, but it is similar to Robinia pseudoacacia seeds.
