1994年甘薯天蛾在鲁中南大暴发,全省累计发生面积240多万亩,仅邹城市统计,损失瓜干就达1200多万公斤。我们根据多年来的数据和今年的长期气象预报、虫口基数等综合分析,预测今年甘薯天蛾仍将大发生。
In 1994, the sweet potato moth broke out in Central Southern Shandong. The cumulative area of the province was more than 2.4 million mu. Only Zoucheng City statistics showed that the loss of melon and dried fruit reached more than 12 million kilograms. Based on the data from many years and the long-term weather forecast of this year and the comprehensive analysis of insect population base, we predict that the sweet potato will still occur this year.
