A kind of breeding method for preserving species of Tetranychus cinnabarinus

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...
