棉铃虫Heliothis armigera(Hubner)和烟青虫H.assulta(Guenée)都是农作物的主要害虫,查阅国内文献和各地资料中有关寄主植物的记载,都把辣椒和烟草列为棉铃虫的主要寄主植物,烟青虫也为害棉花。多年来我们一直没有在棉花上查到过烟青虫,辣椒上没有发现过棉铃虫。为了进一步查清这一问题,在农村落实责任制,农作物种植变得更复杂的情况下又作了一些调查,并在室内作了交换寄主植物的饲养观察。
Both Heliothis armigera (Hubner) and H.assulta (Guenée) are the major pests of crops. According to the domestic literature and the records of the host plants in the local data, both pepper and tobacco are the main host plants of cotton bollworm, Tobacco caterpillars also harm cotton. Over the years we have not been found on cotton tobacco budworm, peppers found on the bollworm. In order to further clarify this issue, some investigations were carried out under the circumstances of implementing the responsibility system in rural areas and further complicating the cultivation of crops. In addition, observations were made on the exchange of host plants in the interior.
