Problems solved by technology

However, the Mediterranean mealworm is a quarantine storage pest in my country, which is not suitable for industrial breeding; although the breeding technology of the rice moth is relatively mature, the development of the rice moth takes a long time, and it needs to be raised for two months at room temperature to lay eggs. The wings of rice moth adults will shed a large amount of scale powder, which is potentially harmful to the respiratory health of workers who collect eggs

Embodiment 1

[0055] Example 1. Comparison of the developmental duration, survival rate and male-to-female ratio of Lygus burgdorferi raised on the eggs of peach aphid and rice moth.

[0056] Test method: the newly hatched 1st instar nymphs of Lygus burgdorferi were reared in a 200ml feeding box, and each feeding box provided about 30 peach aphids or 1 piece of paper (about 1000 grains) full of rice moth eggs. egg), providing a segment of the sesame stalk, the bottom of the sesame stalk is wrapped with wet cotton. The survival and age of nymphs were recorded every day until they emerged into adults, and finally the sex of the emerged adults was recorded. Prey and plant materials were replaced every 3 days. Each treatment had 40 repetitions, and the developmental duration, survival rate and sex of Lygus burgdorferi were counted.

Embodiment 2

[0061] Embodiment 2, raising Lygus burgdorferi with sesame and peach aphid production test

[0062] experiment method:

[0063] Oviposition: First introduce about 400 newly emerged adults of Lygus burgdorferi into the egg-laying cage (the ratio of male to female is about 1:1), then put a box of sesame seedlings inoculated with Myzus persicae, and wait for the birth of Lygus burgdorferi. egg. In the morning after five days, use a bamboo stick to gently scratch the sesame seedlings to drive away the adults of Lygus burgdorferi on the sesame seedlings, and then take out the sesame seedlings that have laid eggs from the egg-laying cage. After taking out, introduce 1 box of new sesame seedlings that have been inoculated with peach aphid in the egg-laying cage. This batch of adults can be used for 5 boxes of sesame seedlings to lay eggs. The spawning process was carried out in the rearing room of Lygus burgdorferi. The environmental parameters of the breeding room of Lygus tabac...

Abstract

The invention discloses a method for feeding nesidiocoris undulatus, which comprises the following steps of: adopting green peach aphids as animal food of the nesidiocoris undulatus, and adopting sesame living plants as host plants of the nesidiocoris undulatus for feeding young nymphs of the nesidiocoris undulatus and for oviposition of imagoes of the nesidiocoris undulatus, so as to feed the nesidiocoris undulatus in an industrialized manner. According to the method, green peach aphids are adopted to replace rice moth eggs to serve as animal food to feed the nesidiocoris undulatus, the production cost is reduced, meanwhile, the high survival rate of adult nesidiocoris undulatus nymphs and the high egg laying amount of female nesidiocoris undulatus nymphs are obtained, and the defect that in the prior art, when an in-vitro plant material is used as an egg laying medium, due to the fact that the hatching period of the nesidiocoris undulatus eggs is long, the nesidiocoris undulatus eggs are high is in-vitro plant materials often wither or rot, and egg incubation is not facilitated.

Description

technical field [0001] The invention relates to a breeding method of predatory natural enemy Lygus burgdorferi, belonging to the technical field of biological control of agricultural pests. Background technique [0002] Predatory stinkbugs are omnivorous or carnivorous natural enemy insects, which can prey on aphids, whiteflies, leafhoppers, thrips, mites, eggs and newly hatched larvae of Lepidoptera insects, etc., many of which are agricultural and forestry pests It is an important natural enemy and is used for the biological control of pests, which has great economic value. Predatory stink bugs are rich in resources, mainly in Anthocoridae, Lygaeidae, Miridae and Pentatomidae. In Europe and the United States, predatory stinkbugs have been able to reproduce in large numbers, and have been used to control crop pests, especially greenhouse pests, and achieved initial success [Cai Wanzhi, Pang Xiongfei, Hua Baozhen, et al. General Entomology [M]. Beijing : China Agricultural...
