Embodiment 1

[0033] Such as figure 1 Shown: a kind of propagation method of Japanese scale-eating wasps, comprising the following steps:

[0034] (1) Treatment of host plants

[0035] Select 3 catties / a complete and mature pumpkin as the host plant, clean the surface with a wet rag, and dry it for later use; mix 70% thiophanate-methyl wettable powder with water to make a 1000-fold medicinal solution; soak the medicinal solution with a rag to treat the pumpkin Disinfect and sterilize the surface, dry it, and place it for 2 days for later use.

[0036] (2) Expansion of intermediate hosts

[0037] Select the rubber paraglycine as the intermediate host; collect the rubber branches with the adults of the paraglycine in the oviposition period (and the newly hatched nymphs crawl out from the adult shell) in the field; put them into the light-proof box with only the upper surface opening For propagation, put a few fresh rubber leaves on the rubber branches; collect the newly hatched nymphs of La...

Embodiment 2

[0041] Such as figure 1 Shown: a kind of propagation method of Japanese scale-eating wasps, comprising the following steps:

[0042] (1) Treatment of host plants

[0043] Pick every 5 jin / one complete and mature pumpkin as the host plant, clean the surface with a wet rag, and dry it for later use; mix 70% thiophanate-methyl wettable powder with water to make a 1000-fold medicinal solution; soak the medicinal solution with a rag to treat the pumpkin The surface is disinfected and sterilized, and left to dry for 3 days;

[0044] (2) Expansion of intermediate hosts

[0045]Select the rubber paraglycine as the intermediate host; collect the rubber branches with the adults of the paraglycine in the oviposition period (and the newly hatched nymphs crawl out from the adult shell) in the field; put them into the light-proof box with only the upper surface opening For propagation, put a few fresh rubber leaves on the rubber branches; collect the newly hatched nymphs of Laxococcus ae...

Embodiment 3

[0049] Such as figure 1 Shown: a kind of propagation method of Japanese scale-eating wasps, comprising the following steps:

[0050] (1) Treatment of host plants

[0051] Select every 4 catties / one complete and mature pumpkin as the host plant, clean the surface with a wet rag, and dry it for later use; mix 70% thiophanate-methyl wettable powder with water to make a 1000-fold medicinal solution; soak the medicinal solution with a rag to treat the pumpkin The surface is disinfected and sterilized, and left to dry for 2.5 days;

[0052] (2) Expansion of intermediate hosts

[0053] Select the rubber paraglycine as the intermediate host; collect the rubber branches with the adults of the paraglycine in the oviposition period (and the newly hatched nymphs crawl out from the adult shell) in the field; put them into the light-proof box with only the upper surface opening For propagation, put a few fresh rubber leaves on the rubber branches; collect the newly hatched nymphs of Laxoc...

Abstract

The invention discloses a method for multiplying the wasps of A. japonica, which comprises the following steps: (1) treatment of host plants (2) expansion and propagation of the intermediate host A. Complex and rejuvenated. The present invention has a simple and efficient method for collecting and inoculating intermediate hosts, which improves the survival rate of the intermediate host, the parasitic wax scale, maximizes the utilization rate of the host plant, increases the parasitism rate of the Japanese scale-eating wasp to the intermediate host, and realizes In order to control the number of pest populations and ensure the effectiveness of field control.

Description

technical field [0001] The invention relates to the technical field of biological control of agricultural and forestry pests, in particular to a method for multiplying the Japanese scale-eating wasps. Background technique [0002] Parasaissetia nigra Nitner, also known as rubber helmets and black parasaissetias, belongs to the order Hemiptera, the family Coccoidea, the family Coccidae, and the genus Parasaissetia. In recent years, the insect has caused a large-scale outbreak on rubber trees, seriously affecting the production and development of natural rubber in my country. [0003] There are many hosts for the paraglobal wax scale. According to records, there are more than 160 kinds of host plants in 36 families. They are important pests of tropical crops such as rubber, cassava, custard apple, citrus, coffee, cotton, guava, oak mango, and papaya. The insect mainly uses adults and nymphs to suck the juice of the leaves and twigs of the host plant, causing the branches and ...
