蚕豆上只有豆蚜(Aphis craccivora)和桃蚜(Myzus persicae)危害,它们都以无翅孤雌成虫或若虫越冬。桃蚜种群密度小。豆蚜种群年际间变化很大。黄皿诱蚜冬季以桃蚜为主,豆蚜数量很少,4～5月豆蚜所占比例增加。冬季蚜虫数量与春季蚜虫发生程度不呈正相关。限制豆蚜种群发展的主要因素是2～3月的雨日和雨量。豆蚜是黄化卷叶型病毒传入蚕豆的主要介体,有翅蚜在春季病毒扩散中起重要作用。低温影响豆蚜的获毒和传毒。在4月,蚕豆黄化卷叶病的潜育期为11～18天。不同年份蚕豆黄化卷叶病的流行不同。春季气候条件特别有利于蚜虫发生,病害大流行。冬前病毒感染少,春季蚜虫少,病害发生轻。
Broad bean is harmed by both Aphis craccivora and Myzus persicae, both wintering with wingless parthenogenetic adults or nymphs. Myzus persicae population density is small. Aphid populations vary greatly over the years. Yellow mulberry aphid-induced winter aphid-based, aphid small number of April to May increased the proportion of aphids. There was no positive correlation between the number of aphids in winter and the occurrence of aphids in spring. The main factor that limits the development of the population of the bean aphid is rainy days and rainfalls from February to March. Bean aphid is the main mediator of yellow curl virus introduced into Vicia faba, aphid plays an important role in the spread of the virus in spring. Low temperature affects bean poisoning and poisoning. In April, the latent period of broad bean yellow curl is 11-18 days. Different years of broad bean yellowing leaf roll prevalence is different. Spring weather conditions are particularly conducive to aphids, disease pandemic. Pre-winter virus infection less spring aphids less, disease occurred light.
