Embodiment 1

[0033] Such as figure 1 Shown: A method for propagation of Japanese scale aphid, including the following steps:

[0034] (1) Treatment of host plants

[0035] Choose 3 kg / piece of complete and mature pumpkin as the host plant, clean the surface with a damp cloth, and dry it for later use; mix 70% thiophanate-methyl wettable powder with water to make 1000 times the liquid; use a cloth to soak the liquid on the pumpkin Disinfect the surface, dry it, and let it stand for 2 days.

[0036] (2) Expansion of intermediate hosts

[0037] Choose the waxy bugs of P. oleracea as the intermediate host; collect the rubber branches with the adult nymphs of P. oleracea during the spawning period (and the newly hatched nymphs crawling out from under the adult shell); put them in a light-proof box with only the upper surface opening For propagation, put a few fresh rubber leaves on the rubber branches; collect the newly-incubated nymphs of P. parasitica and gently sweep the surface of the pumpkin wit...

Embodiment 2

[0041] Such as figure 1 Shown: A method for propagation of Japanese scale aphid, including the following steps:

[0042] (1) Treatment of host plants

[0043] Choose every 5 kg / piece of complete and mature pumpkin as the host plant. Clean the surface with a damp cloth and dry it for later use; mix 70% thiophanate-methyl wettable powder with water to make 1000 times the liquid; use a cloth soaked in the liquid to treat the pumpkin Disinfect the surface and leave it to dry for 3 days;

[0044] (2) Expansion of intermediate hosts

[0045] Choose the waxy bugs of P. parasiticum as the intermediate host; collect the rubber branches with the adult nymphs of P. parasiticum during the spawning period (and the newly hatched nymphs crawling out from under the adult scales); put them in a light-proof box with only the upper surface opening For propagation, put a few fresh rubber leaves on top of the rubber branches; collect the newly hatched nymphs of Leucococcus parasiticus and gently sweep t...

Embodiment 3

[0049] Such as figure 1 Shown: A method for propagation of Japanese scale aphid, including the following steps:

[0050] (1) Treatment of host plants

[0051] Choose every 4 kg / piece of complete and mature pumpkin as the host plant. Clean the surface with a damp cloth and dry for later use; mix 70% thiophanate methyl wettable powder with water to make 1000 times the liquid; use a cloth soaked in the liquid to treat the pumpkin Disinfect the surface and let it dry for 2.5 days;

[0052] (2) Expansion of intermediate hosts

[0053] Choose the waxy bugs of P. oleracea as the intermediate host; collect the rubber branches with the adult nymphs of P. oleracea during the spawning period (and the newly hatched nymphs crawling out from under the adult shell); put them in a light-proof box with only the upper surface opening For propagation, put a few fresh rubber leaves on top of the rubber branches; collect the newly hatched nymphs of Leucococcus parasiticus and gently sweep to the surface...

Abstract

The invention discloses a Japanese coccophagus expanding propagation method. The method includes the first step of host plant preparation, the second step of expanding propagation of an intermediate host, namely parasaissetia nigra, and the third step of expanding propagation and rejuvenation of Japanese coccophagus. The method is a simple and efficient intermediate host collection and inoculation method, the survival rate of the intermediate host, namely parasaissetia nigra, is increased, the utilization rate of host plants is increased to the largest extent, the parasitism rate of Japanese coccophagus on the intermediate host is increased, the number of pest populations is controlled, and the field prevention effect is ensured.

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 propagation of Japanese scale aphid bees. Background technique [0002] Parasaissetia nigra Nitner (Parasaissetia nigra Nitner), also known as rubber helmet scale and jet black pair helmet scale, belongs to Homiptera Hemiptera, Coccoidea Coccoidea, Coccidae Coccidae, Parasaissetia Parasaissetia. In recent years, the worm has exploded on rubber trees in large areas, which has seriously affected the production and development of natural rubber in my country. [0003] There are many host plants of P. arundinacea. According to records, there are more than 160 host plants in 36 families. They are important pests of tropical crops such as rubber, cassava, sugar apple, citrus, coffee, cotton, guava, oak mango, and papaya. The insect mainly sucks the sap of the leaves and twigs of the host plant with adults and nymphs, causing the bran...
