Phytotron for feeding prodenia litura and indoor artificial breeding method

Abstract

The invention discloses a phytotron for feeding prodenia litura and an indoor artificial breeding method. The method comprises the following steps: putting prodenia litura larvae into the phytotron under a specific condition; selecting natural hosts (tobacco leaf, Chinese cabbage and the like) to feed the prodenia litura larvae; changing fresh hosts everyday and removing faeces and rotten leaves; after the prodenia litura larvae pupate, centrally putting the prodenia litura into an insect rearing box; after adult emergence of the prodenia litura, pairing the prodenia litura according to the female-male ratio of 1 to 1, laying eggs and breeding population. According to the feeding method, the prodenia litura are fed in the manmade phytotron, the feeding technique is simple and easy to operate, low in feeding cost, and high in reproductive rate, and standard health test insects can be obtained in an indoor continuous feeding manner.

Description

technical field [0001] The invention relates to an artificial climate chamber for raising Spodoptera litura and an indoor artificial breeding method, belonging to the technical field of insect breeding. Background technique [0002] Spodoptera litura Spodoptera litura Fabricius belongs to Lepidoptera and Noctuidae. It is also known as Spodoptera moth, and its common names are night tiger, five-flowered worm, and hemp worm. It is one of the important agricultural pests in the world. There are as many as 389 species (variety) of host plants in 109 families of this insect, and it eats and damages cabbage Brassica oleracea ,Chinese cabbage Brassica campestris L. spp. Pekinensis (Lour.) Olsson, Chili Capsicum annuum vegetables and wheat Triticum aestivum , rice Oryza sativa and other food crops, but also harm tobacco Nicotiana tabacum and other economic crops. The larvae eat leaves, flower buds, flowers and fruits, and in severe cases, the whole field crops can be...

Problems solved by technology

The larvae eat leaves, flower buds, flowers and fruits, and in severe cases, the whole field crops can be eaten up, causing huge losses to agricultural production

[0003] Spodoptera litura is still mainly controlled by pesticides. Conventional pesticides not only have poor control effects, but also the larvae have generally developed resistance. In addition, the larvae are often hidden in soil crevices and weeds, and it is difficult to contact the insect body when applying pesticides. At the same time, chemical control can also easily lead to changes in the edible safety of vegetables such as cabbage and cabbage and the quality of economic crops such as tobacco, which makes chemical control more and more challenging. In order to effectively control the damage of Spodoptera litura, the population biology of Spodoptera litura, Basic research on population ecology, drug resistance, and governance is necessary. In view of this, it is an important link to breed Spodoptera litura populations indoors in large quantities and for a long time for scientific research experiments.

[0004] At present, the artificial feeding technology of Spodoptera litura is basically devoted to the development and utilization of artificial feed, and the research is relatively mature, but the formula of artificial feeding is not easy to collect, the storage remains unchanged, and some ingredients are expensive. Sexual habits, artificial breeding is difficult to meet the needs of indoor breeding. Lu Baoqian et al. (2013) raised Spodoptera litura on finger tubes or cell culture plates for single-head feeding, but single-head feeding was labor-intensive and wasted feed, and the survival rate was low. Therefore, it is necessary to realize a breeding method for a large number of healthy Spodoptera litura sources in indoor populations
