Large-scale artificial feeding method for eretmocerus hayati

Abstract

The invention relates to a breeding method for a natural enemy insect, in particular to a large-scale artificial feeding method for eretmocerus hayati. The method comprises the following steps of: breeding a host plant of cabbage; breeding a host of bemisia tabaci; and breeding the eretmocerus hayati. The breeding method for the eretmocerus hayati comprises the following steps of: moving cabbage seedlings loaded with nymphs of bemisia tabaci and an insect culture cage to a bee culture room which is taken as a host to culture parasitic bees; taking adult eretmocerus hayati into the bee culture room; removing adult parasitic bees after the adult eretmocerus hayati oviposits; and continuing to culture cabbage plants so that little cream yellow eretmocerus hayati pupae appear on the back of cabbage leaves. The preference temperature for eretmocerus hayati breeding is 24 to 28 DEG C; the suitable intensity for illumination, namely L: D is equal to 14:10; and the suitable humidity is 60 to 80 percent. The large-scale artificial feeding method for the eretmocerus hayati is simple and easy to master, is particularly convenient for indoor breeding and life cycle observation, and can be used for the uninterrupted propagation of the eretmocerus hayati throughout the year.

Description

technical field [0001] The invention relates to a method for raising natural enemy insects, in particular to a method for artificially raising large-scale bees of A. haidenii. Background technique [0002] The whitefly Bemisia tabaci (Gennadius) belongs to the order Homoptera, the family Whitefly family, and the genus Whitefly. Native to tropical and subtropical regions, widely distributed in more than 90 countries and regions around the world, it is one of the main pests of more than 600 kinds of plants such as cotton, vegetables and garden flowers (Liu Shusheng, 2005). Bemisia tabaci can not only directly damage host plants, but also secrete honeydew, which can induce fungal disease, affect photosynthesis, spread plant viruses, and induce crops to produce abnormal physiological reactions, which can harm the normal growth of plants (Davidson et al, 2000). The harm caused by the disease is much more serious than other harms (Feng Lanxiang et al., 2001), and the loss of food...

Problems solved by technology

[0003] In my country, before the mid-1990s, the damage was not serious. According to Chen Liangen (1997), since poinsettia was introduced from abroad in Shanghai area in 1994, Bemisia tabaci began to occur in large numbers on garden crops, and it was difficult to control it with medication.
