为指导蕹菜安全生产,通过整理、汇总甘薯麦蛾历年灯下诱蛾资料和观察记录人工饲养各虫态历期,结合同期气象要素,总结出甘薯麦蛾的发生规律、影响年度间发生程度的气象要素、害虫发生的预测数学模型,在发生早期使用生物制剂白僵菌控制繁殖基数,夏秋季结合其他害虫进行兼治,通过田间农药筛选,找出防治效果稳定、高效、低毒、低残留的农药品种与使用浓度,摸索出最佳绿色防控技术,保障了蕹菜的优质、高产。
In order to guide the safety production of Brasenia schreberi, the information of the moths in the lampworm of the sweet potato and the moths were collected and recorded, and the records of the larvae were recorded and recorded. The occurrence of the moths were summarized with the meteorological elements in the same period, , The forecasting mathematical model of pest occurrence was established. In the early stage, the biological agent Beauveria bassiana was used to control the breeding base. In summer and autumn, the combination of other pests was controlled. The pesticide screening in the field showed that the control effect was stable, efficient, low toxicity and low residue Of the pesticide varieties and the use of concentration, to explore the best green control technology to protect the high quality, high yield.
