Embodiment 1
[0014] Use a box with a length of 20cm, a width of 13, and a height of 4cm with a lid. A 2cm-thick sponge with a section slightly smaller than the box body is placed on the bottom of the box, and a layer of black plastic film with an area slightly smaller than the sponge is laid on the sponge. Add appropriate amount water, the water surface height is about 0.5cm lower than the sponge, surround the black plastic film with a tampon wetted with water, half of the tampon is on the plastic film, and half is on the sponge.
[0015] Dry the washed fresh Erythrina cerana leaves, wrap the petiole with moist cotton, turn the back of the leaf upwards, press the petiole with the above-mentioned cotton sliver, put 6 fresh leaves of Erythrina cerana in each box, and put the cinnabar leaves The mite picks on the blade, and the box cover is reversely covered on the box, and a gap of 2 cm wide is staggered in the box length direction.

Embodiment 2
[0018] Use a box with a length of 25cm, a width of 15cm, and a height of 6cm with a lid. A layer of 2.5cm thick sponge with a section slightly smaller than the box body is placed on the bottom of the box, and a layer of black plastic film with an area slightly smaller than the sponge is laid on the sponge. Add Appropriate amount of water, the water level is about 0.5cm lower than the sponge, surround the black plastic film with a tampon moistened with water, half of the tampon is on the plastic film, and half is on the sponge.
[0019] Dry the washed fresh Erythrina cerana leaves, wrap the petiole with moist cotton, turn the back of the leaf upwards, press the petiole with the above-mentioned cotton sliver, put 8 fresh leaves of Erythrina cerana in each box, put the cinnabar leaves The mite picks on the blade, and the box cover is reversely covered on the box, and a gap of 2 cm wide is staggered in the box length direction.

Abstract
The invention discloses a breed conservation breeding method for Tetranychus cinnabrinus. The method comprises the steps that a box with a box cover is taken, a sponge with the section slightly smaller than a box body is arranged at the bottom inside the box in a cushioned mode, a layer of black plastic film with the area slightly smaller than the sponge is laid on the sponge, a proper amount of water is added, a moisture cotton sliver wraps the black plastic film, a half of the cotton sliver is arranged on the plastic film, and the other half of the cotton sliver is arranged on the sponge; cleaned and fresh erythrina crista-galli leaves are wiped dry, leaf stalk is wrapped by the moisture cotton, the back sides of the leaves face upwards, the leaf stalk is pressed by the cotton sliver, a plurality of fresh erythrina crista-galli leaves are placed, Tetranychus cinnabrinus is picked up to be placed on the leaves, the box cover covers the box reversely, and a gap is formed in the length direction of the box in a staggered mode; according to the breeding condition, the temperature is 25-27 DEG C, the relative humidity is 60-70%, the photoperiod is 14L:10D, and the leaves are replaced with fresh ones every two days. The population size of the Tetranychus cinnabrinus can be effectively controlled, and the population can be stored for a long time, so that the Tetranychus cinnabrinus sensitivity or high resistance strain is obtained.
Description
technical field [0001] The invention belongs to the technical field of acarid breeding, and relates to a species-preserving breeding method of Tetranychus cinnabarinus. Background technique [0002] Tetranychus cinnabarinus is a plant-feeding pest with a wide range of hosts. It damages economic crops and ornamental plants such as various flowers, beans, cotton, vegetables, mulberry trees, and fruit trees, causing serious economic losses. It is a worldwide economic pest. In the process of agricultural production, people use a large number of various insecticides to prevent and control Tetranychus cinnabarinus. A variety of agents have produced drug resistance to varying degrees, and it is considered to be one of the most drug-resistant arthropods in the world. In order to find new environment-friendly insecticides to prevent and control Tetranychus cinnabarinus and effectively control the harm of Tetranychus cinnabarinus, it is necessary to provide a large number of standard...
