Problems solved by technology

However, in the actual operation process, the preparation period of rice seedlings is longer, and it is not easy to obtain them in winter without better indoor cultivation conditions.
In addition, the use of rice seedlings needs to maintain a high humidity of more than 90% in the spawning box. If it cannot be achieved without a humidifier, it will make it difficult for adults to lay eggs.

Embodiment Construction

[0021] The improvement steps of this method mainly lie in the adult egg-laying stage, and the rice seedling feeding method of Shang Zhizhen is still referred to in the larval stage, so only the rice seedling feed is specifically introduced in the following feeding methods.

[0022] 1. Select new rice seeds, soak and accelerate germination;

[0023] 2. Put the germinated rice seeds into a wide-mouth bottle, the amount of rice seeds is about 1 / 3 of the height of the bottle, and when the rice seedlings grow to 2-3cm, use it as the feed for raising the stem borer;

[0024] 3. Put the egg mass of Chilo borer that has developed to the blackhead stage into the above-mentioned jar with rice seedlings, seal the jar mouth with a black cloth, and place it at a temperature of 27±1°C, with light and dark time of 16: 8 hatched in the culture room, the hatched larvae were kept in the bottle and reared under the same conditions;

[0025] 4. When the rice seedlings in the bottle are eaten by ...

Abstract

The invention belongs to the technical field of biological reproduction and cultivation, particularly to a method for artificially feeding Chilo suppressalis in a room. Chilo suppressalis is a polyphagous boring insect, and the indoor artificial feeding of the Chilo suppressalis plays an important role in multiple fields such as assessment of pesticide and the like. The method of the invention mainly uses a ziplock bag with small size, commonly used in a lab, as an egg bed of the Chilo suppressalis, and not only the materials is easily accessible, but also the specific operation of collecting egg masses is simplified further, at the same time, the method uses a plastic box with size of 20*15*15(cm) as a container, so the space occupied by the whole oviposition equipment in the method is smaller than that during using rice seedlings. In the invention, an improved method for artificially feeding Chilo suppressalis in the room is provided, and oviposition process of the Chilo suppressalis adult is simplified in the process of artificially feeding the Chilo suppressalis in the room, and enough egg masses can be produced for going down to the future generation.

Description

technical field [0001] The invention belongs to the technical field of biological propagation and cultivation, and in particular relates to a method for artificially raising Chilo suppressalis indoors. Background technique [0002] Chilo borer Chilo suppressalis (walker) belongs to Lepidoptera Boreridae, and is the main pest of rice in my country. Chilo borer is widely distributed in my country. Except for a few areas where no damage has been found, it is distributed in the north and south rice fields. The area damaged by Chilo borer is 10 million hm2 every year. Chilo borer is an omnivorous pest. In addition to harming rice, it also harms wild rice stems, wild wild rice stems, sugar cane, sorghum, corn, wheat, barnyard millet, broad beans, rapeseed and other crops. At present, in addition to field work in the field, the research on Chilo suppressalis requires a large number of insect populations with the same developmental progress for bioassay and other experiments in th...
