Abstract

The utility model discloses a device that wheat leaf claw mite egg period was observed, including circular transparent plastic preservation box, sponge, filter paper, 200 mesh gauze. The sponge is cut into a circle with the same size as the circular plastic preservation box, the circle is placed at the bottom of the circular transparent plastic preservation box in a soaked mode, then the filter paper slightly smaller than the sponge is placed on the surface of the sponge, the preservation box is covered with a 200-mesh gauze, and finally the preservation box cover with air holes is used for covering. This novel device that adopts simple structure, simple operation will realize a large amount of collections of wheat leaf mite ovum in the same period to the complete clear development epoch and the biological characteristic etc. of observing the ovum are favorable to the systematic research in later stage of wheat leaf mite ovum.

Description

Device for observing egg period of wheat leaf mites

Technical Field

The utility model belongs to the technical field of the indoor contemporary ovum collection method of wheat leaf mite and ovum phase viewing device, specifically relate to a device is surveyed to a large amount of collections of wheat leaf mite ovum and ovum phase.

Background

The Trionycis mylabris is an important pest mite on wheat in China, which occurs in 3-4 generations every year, and the duration of the pest is as long as about 160 days. It generally produces two different physiological types of eggs, winter non-diapauzing and summer diapauzing. The current research shows that the eggs have the characteristics of heat resistance, drug resistance and the like, but the collection mode and the development period observation device of the eggs of the indoor population are not clear. Therefore, it is very urgent to specify a method for collecting a large number of eggs of the Onychidae and an observation apparatus for observing the development period.

The hemimorpha graminifolia is small in size, leaf juice is mainly sucked from the seedling stage to the heading stage of wheat, when the field temperature is stabilized to be above 20 ℃, the quantity of the hemimorpha graminifolia is reduced sharply, and the hemimorpha graminifolia mainly depends on a large amount of eggs to cross summer. The mites on the root of the soil surface and the roots of the stalks are small in size, so that the number of the mites is difficult to calculate, the collection efficiency is low, and great inconvenience is brought to the study of the life history and the basic biological characteristics of the mites. The invention aims to provide a method for collecting a large number of eggs of the acarus molesta in the same period and a device for observing the egg period.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a method and the viewing device of wheat schneiderian mite egg period of indoor high-efficient collection wheat schneiderian mite egg.

The technical scheme of the utility model is realized like this: the utility model provides a device that wheat leaf claw mite egg period was observed which characterized in that: comprises a transparent box, a sponge which is soaked by water and matched with the inner section of the box body is arranged in the box, filter paper is arranged on the upper surface of the sponge, a gauze is covered on the top of the box, and a cover with air holes covers the box.

The transparent box is a plastic preservation box, and the cover is a preservation box cover.

The transparent box is barrel-shaped.

The gauze is 200 meshes.

A method for collecting the eggs in the same period of the Onychidae myxoma comprises the following steps: cutting fresh wheat leaves into small sections with the length of 3-4cm, placing 2-5 sections of wheat leaves on the surface of a soil layer of the device for feeding the wheat leaf mites in the oviposition period according to the mite forming amount in the device, and according to the oviposition habit, a large amount of eggs are laid at the two ends and the surface of the wheat leaves. According to the requirement of the test, a large amount of eggs in the same period can be conveniently and quickly collected.

Since the technical scheme is used, the utility model has the advantages of simple structure, simple operation, adopt it not only can high-efficiently collect the ovum of a large amount of wheat puccoon in the same period, can also observe biological parameters such as the concrete development calendar of its ovum, hatchability.

Drawings

In order to more clearly illustrate the technical solution of the novel implementation of the experiment, the drawings used in the description of the embodiments will be briefly introduced below.

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.

In the figure: 1 is a circular transparent plastic preservation box with a cover and air holes, 2 is a circular sponge, 3 is a 200-mesh square gauze and 4 is filter paper.

Detailed Description

The device for observing the egg period of the wheat cyromazine comprises a circular transparent plastic preservation box, sponge, filter paper and a 200-mesh gauze. The sponge is cut into a circle with the same size as the circular plastic preservation box, the circle is placed at the bottom of the circular transparent plastic preservation box in a soaked mode, then the filter paper slightly smaller than the sponge is placed on the surface of the sponge, the preservation box is covered with a 200-mesh gauze, and finally the preservation box cover with air holes is used for covering.

Wherein the diameter of the round transparent plastic preservation box is 12cm and 8 cm; the diameter of the round sponge is 10 cm; the diameter of the 200-mesh square gauze is 15 cm; the filter paper had a diameter of 9 cm. The 200-mesh gauze on the round transparent plastic preservation box has the functions of ventilating, regulating and controlling humidity and preventing sundries from entering the preservation box.

The method specifically comprises the following steps:

1) placing 3-4cm of fresh wheat leaves on the surface of a soil layer of a feeding device in the oviposition period of the Panonychus tritici;

2) taking out the wheat leaves on the surface of the soil layer in the feeding device in a corresponding time period according to the test requirements;

3) placing the wheat leaves on the surface of the soaked filter paper, slightly poking the eggs on the wheat leaves with a small brush pen, placing the eggs on the surface of the filter paper in order, and simultaneously removing the wheat leaves without the eggs;

4) adding a proper amount of water into a round plastic preservation box to keep the sponge and the filter paper in the preservation box in a wet state all the time, covering a cover of the preservation box, placing the preservation box in a constant-temperature constant-humidity artificial climate box (15 +/-1 ℃, 75 +/-5% R.H, L: D =10: 14), observing once every 12h, and recording biological parameters such as the development period, the hatching rate and the like.

The utility model discloses profitable technological effect is: adopt simple structure, simple operation's device will realize the collection in a large number of wheat schneiderian ovum in the same period to the complete clear observation ovum develop duration and biological characteristic etc. are favorable to the later stage systematic research of wheat schneiderian ovum.
