Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the examples.

[0020] Embodiment (raising condition: temperature 24 ℃, photoperiod: dark period=14:10h, humidity 70%, and all are constant)

[0021] 1) Egg hatching: Take out the eggs of Armyworm Lloyd’s worm stored at 4°C and put them into a glass bottle, add enough fresh young corn leaves to moisturize the bottle, replace the corn leaves every two days, and turn off the eggs when they are found to turn black. It is about to hatch, and the corn leaves can no longer be replaced at this time. To prevent the hatched larvae from being lost, only corn leaves can be added inside.

[0022] 2) 1-3 instar larvae: The larvae in this stage basically do not eat, as long as the corn leaves in the bottle are fresh, you can cover the bottle with a wet towel for multiple moisturizing. Try not to subpackage the larvae at this stage to avoid man-made mechanical damage. The age of the larvae is general...

Abstract

The invention relates to a method for raising Armyworm lauleyi. The method mainly includes the following steps: (1) Preservation and hatching of eggs: eggs can be hatched as required at 4°C; (2) 1-3 instar larvae: hatched larvae need to be added with fresh and tender corn leaves (3) 4‑6 instar larvae: the larvae at the end of the 3rd instar stage start to pack, 10 heads / 750ml glass bottles, and replace fresh corn leaves every day; (4) Pupa: mature larvae need to be pupated in sterile water containing 10% (5) collecting adults: the adults that have emerged need to supplement nutrition. Adopt a kind of rearing technology of armyworm lauley described in the present invention, under the condition of temperature 24 ℃, photoperiod:dark period=14:10h, humidity 70%, have high survival rate, high egg production, simple and convenient feeding etc. Advantages, it can be used for scientific research and large-scale breeding.

Description

technical field [0001] The invention relates to an insect feeding technique, in particular to a feeding method of the main crop pest, Armyworm lauleyi. Background technique [0002] Leucania loreyi belongs to Lepidoptera Noctuidae, is a worldwide pest, occurs in Africa, Asia, the Middle East and Australia, can have multiple generations every year, and can eat rice, wheat, barley, sorghum , Corn And Sugar Cane. In my country, it mainly harms wheat, corn and rice. It has not been reported as a major pest at present, and it often occurs mixed with Oriental armyworm Mythimna separata in southern my country. Armyworm orientalis is a major food crop pest in my country. It has a typical migratory habit and migrates back and forth from north to south in my country. The larvae and pupae of Armyworm orientalis are very similar to those of Armyworm orientalis and difficult to be distinguished, and their developmental periods are different. quick. These have caused interference to t...
