Embodiment Construction

[0021] Such as figure 1 , figure 2 It is the device in a specific embodiment of the present invention, and device comprises a container 20, and this container one end is closed by the bottom, and the other end is open, and the place of opening is closed by gauze 10, and the container comprises a plastic material with a height of 0.5-1.0 cm. Cushion 21, filter paper 24 is placed on the plastic cushion; at the same time, a certain amount of water 23 is included in the container 10, and the height of the water is as the criterion not exceeding the plastic cushion. Suspend absorbent cotton balls 40 in the container simultaneously, and be dipped in 10% honey water on the cotton balls as the supplementary nutrition of rice leaf roller adults. When using the device, keep the gauze closing the opening moist.

[0022] In another preferred way, such as figure 2 , the device can be placed in a container 30 filled with water 31, and the skirt 22 of the gauze is immersed in the water ...

Abstract

The invention relates to an egg laying device of cnaphalocrocis medinalis guenee and a use method. The device comprises a 500-2000ml glass container, wherein the container is provided with a bottom and an opening; a grid-shaped plastic pad is arranged at the bottom of the container and is covered by filter paper; an absorbent cotton ball dipped with 10% of hydromel is hung in a beaker; the container contains water which does not immerse the plastic pad; and two layers of gauzes for sealing the opening of the container are arranged at the opening of the container. The device is simple in production, low in cost and easy to operate and has the advantages of prolonging the lives of cnaphalocrocis medinalis guenee adults, ensuring large egg number per female, improving the egg collecting efficiency, etc.

Description

technical field [0001] The invention relates to the technical field of insect feeding, in particular to an egg-laying device for the rice leaf roller and a method for using the same. Background technique [0002] Rice leaf roller, scientific name Cnaphalocrocis medinalis Guenee, belongs to Lepidoptera (Lepidoptera) Pyralidae, is an important migratory pest that damages rice in my country, also known as scraper caterpillar. It is distributed in various rice areas across the country from Heilongjiang and Inner Mongolia in the north to Taiwan and Hainan in the south. The adult bracts of rice leaves are rolled vertically by the larvae, and the larvae hide in it to feed on the mesophyll, leaving only the epidermis, forming white streaks and affecting photosynthesis. In the middle and late stages of rice, it will damage the upper functional leaves and affect the filling, resulting in unfulfilled seeds, increased empty grains, and reduced thousand-grain weight. Generally, the yiel...
