Problems solved by technology

The current release research mostly uses larvae or eggs as the released insect state, but these two insect states cannot meet the requirements of long-distance transportation due to their own biological characteristics, which restricts the release application of ladybugs.

Embodiment 1

[0025] Collection of overwintering Heterochromia

[0026] From October 10th to 20th (Jilin area) Heterochromia was concentrated on sunny hillsides and walls of tall buildings in order to find overwintering places. The system is converted into a DC power supply, that is, it is powered by a battery. The voltage of the selected battery is 12V. One battery can drive three 75W vacuum cleaners to work continuously for more than 15 hours, and can be collected directly on the exposed hillside or wall surface. The collection capacity of a single machine is 80 to 150 million heads per hour, and the mechanical damage rate is less than 0.5%.

[0027] Low temperature storage of overwintering generation Heterochromia

[0028] The collected heterochromia ladybugs are divided into cotton bags with a size of 30cm*40cm. There is a certain amount of folded paper inside the bag as a carrier for ladybugs. The size of the paper is 5cm wide and 30cm long; fold along the length direction and survive...

Embodiment 2

[0036] The main body is a closed square box 1 with a side length of 5 cm, and the material is made of high-density cardboard (see figure 1 ). A round hole 2 with a diameter of 3 cm is left on both sides, and the round hole 2 is closed with a thin paper 3; the inner bottom of the box body 1 has a cylindrical groove 4 with a diameter of 2 cm and a height of 1.5 cm, which is used for placing honey water absorbent cotton (the amount of honey water depends on the transportation distance) to ensure the supplement of water and nutrition during transportation; there is a hook 5 in the middle of the top of the box body 1. When releasing, pull up the hook 5 and directly hang the release box At the release point, pierce the thin paper on the side, and the ladybugs can crawl out from the round hole 2, and the capacity of holding insects is 50.

Abstract

The invention discloses an overwintering generation harmonia axyridis collection, low-temperature storage and release method. A negative suction type dust sucking device is selected as a device for collecting the overwintering generation harmonia axyridis; the collected harmonia axyridis is put in a refrigeration house or an ice tank for low-temperature storage, wherein the storage mode is that the collected harmonia axyridis is packaged into a cloth bag, and folded paper serving as a harmonia axyridis overwintering carrier is arranged inside the cloth bag; the release amount is determined based on the production of the control targets according to the seasonal production of the insects, and the harmonia axyridis is directly put on crops to be protected; and a box type device for transporting and releasing the harmonia axyridis is selected. A negative pressure device is selected as a collecting device to realize the rapid extensive collection of the overwintering generation harmonia axyridis; the refrigeration house or the ice tank is used for storage so as to realize long-term storage of the overwintering generation harmonia axyridis; the overwintering generation adults are selected as released insects; and the method solves the problem that two insect forms of the harmonia axyridis cannot meet the requirement on long-distance transport due to biological characteristics per se and restrict the release application of the harmonia axyridis.

Description

Technical field: [0001] The invention belongs to the technical field of biological control of agricultural pests, in particular to a collection, low-temperature storage and release method of overwintering generation heterochromia. Background technique: [0002] The heterochromia involved in the present invention belongs to Coleoptera and Coccidae, and is used as the main predatory natural enemy of aphids, scale insects, whiteflies, psyllids, mites and Lepidoptera insect eggs and newly hatched larvae Insects have the characteristics of large predation, wide distribution, strong fecundity, and strong adaptability. Ideal biological control agent. However, because there are still many technical deficiencies in the artificial breeding of Heterochromia, commercial production is still not possible, which restricts the release and application of Heterochromia to a certain extent. [0003] At present, the existing literature and patent reports about the collection of ladybugs all a...
