The rice leaf roller larvae of the laboratory population are bred by using living wheat and placed in an insect breeding cage, and the length, width and height of the insect breeding cage are 40cm respectively. After the imagoes are eclosized, the activities of the rice leaf rollers imagoes can be observed in the insect rearing cage.

Referring to fig. 1, the embodiment of this application provides a device that is used for rice leaf roller adult collection and its ovum grain to collect, including mating cup 1, mating cup 1 is the hollow cylinder that the top has open lower extreme confined, is equipped with the opening on the lateral wall of mating cup 1 (not shown in the figure), and the opening part is equipped with collection pipe 2, and collection pipe 2 is close to the bottom setting of mating cup 1, and collection pipe lid 3 is established to the opening part of collection pipe 2. The collecting tube cover 3 can prevent the rice leaf roller imagoes entering the mating cup 1 and the collecting tube 2 from escaping. Specifically, gather pipe 2 and be hollow cylinder, gather the through-hole diameter of pipe 2 and the opening diameter equals on the lateral wall of mating cup 1, and the axis of gathering pipe 2 is perpendicular with the axis of mating cup 1, and the opening part of gathering pipe 2 is equipped with external screw thread 22, and the oral area of gathering the pipe lid 3 is equipped with the internal thread 31 with this external screw thread 22 looks adaptation. In order to prevent the hand of the operator from slipping when screwing the collection tube cover 3, the outer side surface of the collection tube cover 3 is provided with anti-slip threads 32.

The opening of one end of the collecting tube 2, which is far away from the mating cup 1, is an insect collecting opening 21, the opening of the other end of the collecting tube is an insect conveying opening, the drift diameter of the insect collecting opening 21 is equal to that of the insect conveying opening, the collecting tube 2 is short, specifically, the height of the mating cup 1 is 14.2cm, and the caliber of the mating cup is 10.8 cm; the drift diameter of the collection tube 2 is 2.7cm, and the length is 3.5 cm; the height of the collection tube cover 3 is 1 cm.

In order to facilitate the collection and transfer of the rice leaf roller imagoes in the mating cup 1, a handle 6 is arranged on one side of the mating cup 1, which is far away from the collection pipe 2.

Specifically, mating cup 1 and collection pipe 2 are integrated into one piece spare, from this, through seamless rigid coupling between the two, the rice leaf roller adult who conveniently gathers leads to in mating cup 1 for the collection of rice leaf roller adult once only accomplishes with the step of accomodating.

The oral area of mating cup 1 covers ventilative layer 4, and mating cup 1 forms the enclosure space (not shown in the figure) that is used for the rice leaf roller adult mating and lay with ventilative layer 4, collection pipe 2 and collection pipe lid 3 jointly, and the circulation of air of enclosure space and outside can be guaranteed to ventilative layer 4. In order to simplify the structure, the air permeable layer 4 in the embodiment of the present application is a plastic preservative film, the plastic preservative film is provided with air permeable holes 41, and the plastic preservative film is bound at the opening of the mating cup 1 through a binding rope 5. Specifically, the air holes 41 are a plurality of through holes for binding the plastic preservative film 4 with toothpicks, and the binding rope 5 is a rubber band. Therefore, after the rice leaf roller adults lay eggs, most eggs can fall on the plastic preservative film at the top, the survival rate of the eggs is high, and the eggs are convenient to collect.

Be equipped with the humidification piece in the enclosure space, the humidification piece can guarantee to have higher humidity in the enclosure space, provides high-quality oviposition environment for the rice leaf roller adult. Specifically, the humidifying part is a cotton ball degreased with 10% of honey water, so that energy can be provided for male and female rice leaf rollers.

For the convenience of observation, the mating cup 1 and the collecting tube 2 are transparent pieces. Specifically, mating cup 1 can be the working of plastics with gathering pipe 2, from this, whole device is lighter, also more prevents falling. The mating cup 1 and the collection tube 2 may be made of organic glass or resin, and are not limited herein.

The process of collecting the rice leaf roller adults and collecting the eggs of the rice leaf roller adults by using the embodiment of the application is as follows:

1. a plurality of absorbent cotton balls containing 10% of honey water are placed at the bottom of the inner side of the mating cup 1, the opening is covered with a plastic preservative film and sealed, the plastic preservative film is fixed by a rubber band, and a plurality of small holes are pricked on the plastic preservative film by toothpicks to ensure the air circulation in the mating cup 1.

2. The collection tube cover 3 is opened.

3. Open the door of insect rearging cage one side, handheld this application embodiment, will adopt insect population 21 to aim at a static rice leaf roller adult, cover it from its top down, simultaneously with adopting insect population inner wall to bump the belly end of this worm gently, the rice leaf roller adult of being restricted activity can pass through collection pipe 2 rapidly, from defeated insect population fly into mating cup 1 in, so, accomplish a rice leaf roller adult and gather the action promptly. If a plurality of rice leaf roller adults need to be collected, the collecting action needs to be repeated for a plurality of times.

4. After the collection is completed, the collection tube cover 3 is screwed down, the insect collection opening 21 is closed, and collected adult rice leaf rollers are accommodated into the mating cup 1. In general, female insects mate with male insects after eclosion for one day, most of eggs are laid on a preservative film at the top end of a mating cup 1 after eclosion for three days, egg grains on the preservative film can be collected as required, and the collection work of the rice leaf roller egg grains is completed.

The above is only an embodiment of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions within the technical scope of the present disclosure should be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
