南美斑潜蝇为近年入侵云南的主要害虫,属多食性的斑潜蝇种类,其虫体小,生活周期短,繁殖力高,取食活动隐蔽,范围广,适应性强,对农药易产生抗性,加之我省适宜的气候和丰富的寄生植物等重要生态因子,因此,容易暴发成灾,尤其以蚕豆作物受害较重。蚕豆斑潜蝇发生危害特点及防治关键时期在我省蚕豆产区均有斑潜蝇的发生,一般有两次危害高峰。第一次危害高峰为秋末冬初(10月下旬至12月上中旬)的蚕豆生长前期,此时是蚕豆保苗、保正常生长、压低前期田间虫口基数进行药剂防治的关键时期;第二次高峰出现在开春气温回升后,即2月下旬至4月上旬蚕豆开花至荚果期,以后随着蚕豆成熟近收获,植株
The South American Liriomyza sativae is the main insect pest in Yunnan in recent years. It is a polyphagous species of Liriomyza sativa, which has small parasites, short life cycle, high fertility, concealed feeding, wide range, strong adaptability, Resistance, coupled with the province’s appropriate climate and abundant parasitic plants and other important ecological factors, therefore, prone to outbreaks, especially heavy crops Vicia crops. Vicia faba Leafhopper Occurrence characteristics and prevention and control of key period Vicia faba production area in our province have the occurrence of leaf miner, there are generally two hazards to the peak. The first peak of harm is the early growth of Vicia faba in the late autumn and early winter (late October to early December), at this time the key period for seedling prevention and treatment of Vicia faba and normal growth and depressing the pre-field insect population base to prevent and control pesticides. The second peak Appear in the open spring temperature rise, that is late February to early April broad bean flowering to the pod period, after the harvest as Vicia faba near, plants
