近年来,各地对小地老虎越冬和迁飞两方面进行了一系列的研究,我们也在室内做一部份工作,现将80—81年结果扼要介绍如下: 一、大规模人工饲养小地老虎幼虫60年代初期,南京农学院昆虫教研组曾用各种饲料植物饲养小地虎幼虫,其中,以菊科植物(如莴苣、蒲公英、向日葵等)饲料最好,老熟幼虫体重可达700毫克,雌蛾产卵量在1000粒以上。但在饲养中存在一些问题:一是连续饲养两代以后有退化现象,二是周年供应新
In recent years, a series of researches have been conducted on the overwintering and migrating of small tigers in various places, and we have also done some work indoors. The results of the 80-81 years are summarized as follows: I. Large-scale artificial breeding of small land Tiger larvae In the early 1960s, Nanjing Agricultural College Insect Teaching and Research Group had used a variety of feed plants to feed small land tiger larvae, among them, to Compositae (such as lettuce, dandelion, sunflower, etc.) feed the best larvae weighing up to 700 mg , Females oviposition in more than 1000. However, there are some problems in rearing: First, there are degenerative phenomena after two generations of rearing; second, the annual supply of new
