Embodiment 1

[0027] A method for multiplying the Japanese scale-eating wasp drone, comprising the following steps:

[0028] (1) Treatment of host plants

[0029] Pumpkins were selected as host plants, and the wettable powder of thiophanate-methyl was prepared into a liquid medicine with clear water, which was sprayed on the surface of pumpkins for disinfection and sterilization and then dried.

[0030] (2) Cultivation of primary hosts

[0031] Collect the newly hatched nymphs of A. acanthus and inoculate them on the surface of pumpkins for cultivation. The cultivation temperature is 24°C to form a test population with pumpkins as the host. Turn the pumpkins once a day for a week to make the surface of the pumpkins. The newly-hatched nymphs of Saccharomyces japonicus are evenly distributed, and the honeydew secretions are regularly cleaned during the cultivation process until the nymphs of Saccharomyces cerevisiae grow to 3 days old, and they are used for later use. A part is used to inoc...

Embodiment 2

[0037] A method for multiplying the Japanese scale-eating wasp drone, comprising the following steps:

[0038] (1) Treatment of host plants

[0039] Pumpkins were selected as host plants, and the wettable powder of thiophanate-methyl was prepared into a liquid medicine with clear water, which was sprayed on the surface of pumpkins for disinfection and sterilization and then dried.

[0040] (2) Cultivation of primary hosts

[0041] Collect the newly hatched nymphs of A. acanthus and inoculate them on the surface of pumpkins for cultivation. The cultivation temperature is 26°C to form a test population with pumpkins as the host. Turn the pumpkins once a day for a week to make the surface of the pumpkins. The newly-hatched nymphs of Saccharomyces japonicus are evenly distributed, and the honeydew secretions are regularly cleaned during the cultivation process until the nymphs of Saccharomyces cerevisiae grow to 3 days old, and they are used for later use. A part is used to inoc...

Embodiment 3

[0047] A method for multiplying the Japanese scale-eating wasp drone, comprising the following steps:

[0048] (1) Treatment of host plants

[0049] Pumpkins were selected as host plants, and the wettable powder of thiophanate-methyl was prepared into a liquid medicine with clear water, which was sprayed on the surface of pumpkins for disinfection and sterilization and then dried.

[0050] (2) Cultivation of primary hosts

[0051] Collect the newly hatched nymphs of A. acanthus and inoculate them on the surface of pumpkins for cultivation. The cultivation temperature is 25°C to form a test population with pumpkins as the host. Turn the pumpkins once a day for a week to make the surface of the pumpkins. The newly-hatched nymphs of Saccharomyces japonicus are evenly distributed, and the honeydew secretions are regularly cleaned during the cultivation process until the nymphs of Saccharomyces cerevisiae grow to 3 days old, and they are used for later use.

Abstract

The invention discloses a method for multiplying the Japanese scale-eating wasp drone, comprising the following steps: (1) treating the host plant; (2) cultivating the primary host; (3) cultivating the secondary host; (4) cultivating the Japanese food plant Breeding of aphid wasp drones. The present invention adopts the method of changing the parasitic mode to increase the proportion of drones, and uses the parasitoid bee as the primary host to help maintain the parasitic force of the Japanese scorpion wasp to the scorpion, and maintain the field control effect, and proposes the Japanese scorpion The optimum interval time between two parasitizations of wasps, the optimum age of the host and the proportion of receiving bees and other conditions have improved the propagation efficiency of the drones of A. japonicus, and can realize mass production and reproduction of high-quality wasps. , and can effectively solve the problem of low reproductive efficiency, and realize the control of the pest population.

Description

technical field [0001] The invention relates to the technical field of agricultural and forestry pest control, in particular to a method for multiplying the drone of the Japanese scale-eating aphid wasp. Background technique [0002] Parasaissetia nigra Nitner is a multi-host pest. According to records, there are more than 160 kinds of host plants in 36 families. An important pest. In order to prevent and control the spreading hazards of L. aeruginosa, the main control method at present is to use organophosphorus chemicals such as dimethoate, chlorpyrifos, and Alben for spray or smoke control. At present, because the above-mentioned agents used are low-to-medium toxic agents, the effect on scale insect pests is biased. In addition, because the trees of rubber trees are tall, it is difficult to send the agents to the affected parts of the rubber tree by spraying. The lack of types of medicaments leads to unsatisfactory prevention and treatment as a whole. [0003] The use ...
