Embodiment 1

[0030] Such as figure 1 As shown, a device for collecting a lepidoptera insect larvae parasitic bee, including a box 1, a cover 2, a pillar 3, and a leg 4;

[0031] The box is opened, the bottom is closed, and the opening of the three sides is enclosed with a yarn network 11, and a side door 12 is provided at the opening of one side. There are a plurality of casings in the casing 1 (not shown). The mesh pore size of the yarn network 11 is greater than the target squared insect larvae, and smaller than the lepidoptera insect larvae.

[0032] The cover 2 is made of a spine, which is made of the non-transmissive material, fixed to the top of the box 1; the cover 2 is protruded from the upper edge of the casing 1 four weeks.

[0033] The pillar 3 is 4, respectively, respectively, respectively, the bottom of the casing 1.

[0034] The leg 3 is a hollow cup shape, the opening up, and the leg 3 is provided with a mounting groove for fixing the strut 3, and the bottom end of the strut 3 i...

Embodiment 2

[0036] The wildfish insect larva shivele with the cotton bollworm toothis is the target, using the device (11 mesh yarn net) in Example 1 to collect the wild collection of cotton bollworm.

[0037] 1) Place the device in the cotton field in which the cotton bollworm teeth did not, 100 heads of the 1-2-years cotton bell larvae and larvae artificial feed were placed in the boxes in each box;

[0038] 2) Make a 20% formalum solution to each of the feet, so that the bottom of the strut is soaked in the formalin solution;

[0039] 3) Every 96h, collect the cotton bollworm larvae in the box, and put into the new cotton bollworm larvae and larvae artificial feed; bring the collected cotton bollworm larvae back to indoors, with an average of more than 50% of the cotton bollworm larvae parasitic. Compared to artificial collection, saving 200 yuan / person / day, and artificial collection is often collected.

Embodiment 3

[0041] The field of parasitic bee was taking a parashot of the target squared insect larvae, and the field collection of the velvet bee was carried out using the device (11 mesh net) in Example 1.

[0042] 1) Place the device in a roof, soybean and other crop fields, and take the 2-year-old twill moth larvae 100 and larvae artificial feed to the casing of each box, close the side door;

[0043] 2) Make a 30% formalin solution to each of the feet, so that the bottom of the strut is soaked in the formalin solution;

[0044] 3) Every 96h, the rough night moth larva in the box is collected, and the new twill manda larvae and larvae artificial feed are placed in the box; the collected twill moth larvae is returned to the indoor feeding, with an average of more than 20% of the twill Night moth larvae was parasitic. Compared to artificial collection, saving 200 yuan / person / day, and artificial collection is often collected.

Abstract

The invention discloses a device and method for collecting parasitic wasps of lepidoptera insect larvae in field, and belongs to the technical field of field artificial collection of natural enemy insects. The device comprises a box body, a box cover, support columns and support legs; the bottom of the box body is closed, the side faces are open, the side faces of the box body are surrounded and covered by gauze and provided with side doors, and multiple boxes are placed in the box body; the box cover is fixed at the top of the box body; the support columns support the bottom of the box body;and the support legs are hollow-cup-shaped, openings are upward, and the bottom ends of the support columns are fixed in the support legs. The invention also discloses a method for collecting the parasitic wasps of the lepidoptera insect larvae by using the device. The device is simple in structure, the method is simple, the cost is low, the usability is high, the collecting efficiency is high, and collection of a large number of parasitic wasps of the lepidoptera insect larvae for a long time can be achieved.

Description

Technical field [0001] The present invention belongs to the field of artificial collection of natural enemy insects, which specifically involves a device and method of a wild-collected lepidoptera insect larvae parasitic bee. Background technique [0002] The parasitic bee of the lepidoptera insect larvae has the characteristics of strong special, and it is often breed, and it is often used in the biological prevention and control of agricultural and forestry pests to reduce the use of anti-insect pesticides in agricultural production, and protect agricultural production safety and agricultural products Safety and farmland ecological security. [0003] The short-parallel insect larvae, which is currently used, is mainly captured by artificial fields, and its collection efficiency is low, and it is not suitable for long-term large continuous collection. [0004] Therefore, how to provide an apparatus for the wild semaphore insect larva parasites to save manpower, which is an urgen...
