Diaphorina citri Kuwayama parasitism natural energy scale breeding method

Abstract

The invention discloses a diaphorina citri Kuwayama parasitism natural energy scale breeding method. Insects and germs on a Murraya exotica plant are eliminated to obtain a clean Murraya exotica without disease and pest infection. The clean Murraya exotica without the disease and pest infection is transferred to a first greenhouse or a first insect rearing cage, and the diaphorina citri Kuwayama is grafted to breed. Under normal lighting conditions, the Diaphorina citri Kuwayama is cultured and bred under the temperature of 22 to 28 DEG C, and the Murraya exotica or the Diaphorina citri Kuwayama is supplemented at any moment according to requirements. The clean Murryaya exotica without the disease and pest infection is transferred to a second greenhouse or a second insect rearing cage, and the Diaphorina citri Kuwayama in the first greenhouse or the first insect rearing cage is grated. Under the normal lighting conditions, the Diaphorina citri Kuwayama is cultured to spawn and grow to a nymph of 4-5 years old under the temperature of 22 to 28 DEG C. The parasitic wasp and parasitic Diaphorina citri Kuwayama are utilized for inoculation, and the parasitic wasp can be colleted after 7 to 10 days. According to the Diaphorina citri Kuwayama parasitism natural energy scale breeding method, the industrialization production of the Diaphorina citri Kuwayama parasitic wasp is achieved.

Description

Technical field: [0001] The invention belongs to the field of insect breeding, and in particular relates to a method for large-scale breeding of parasitic natural enemies of citrus psyllids. Background technique: [0002] Citrus Huanglongbing (HLB) is a destructive disease that occurs in many major citrus producing countries such as China, the United States, and Brazil, and poses a serious threat to the world's citrus production. In recent years, citrus huanglongbing has spread continuously in some citrus producing areas in my country, causing serious losses to some areas. The citrus psyllid Diaphorina citri Kuwayama is the only insect vector of citrus HLB, and its control is considered to be the key to control HLB. In recent years, researchers have found that the control of citrus psyllid in citrus production still has many problems in the critical period and methods of control. The inventor of this patent has put forward some suggestions (Mao Runqian et al., 2014). It i...
