Problems solved by technology

Since the red fat beetle was introduced into my country, its living habits have undergone great changes. 70%-80% of the individuals burrow into the roots and cause harm, which makes it more difficult to control this pest
At present, the methods of preventing and controlling the red beetle in my country are mainly to clean up the pest wood and fumigate with chemical pesticides. Although these methods can achieve some control effects, they are labor-intensive, time-consuming, costly, pollute the environment, and cannot fundamentally achieve complete control of pests.

Embodiment 1

[0061] Embodiment 1 The adult beetle of the maggot lays eggs

[0062] The room temperature is 19°C and the humidity is 75%.

[0063] Put 2 / 3 of the sawdust in a circular culture box (diameter×height=10cm×1cm), and mix the sawdust with distilled water until no water drops can be squeezed out by hand. Place 80 adults of the large beetle beetle (40 pairs of male and female adults) and 1 larvae of the red beetle in the sawdust, cover the box lid, put it in a dark place, and replace it with a fresh host every day.

[0064] The eggs of the big scorpion are oblong, white, translucent, and less than 2mm. The number of eggs is counted every day. When the number of eggs in the culture box is about 100, the adults are picked out and replaced with a new culture box.

[0065] Using the same feeding conditions and methods, adjust the stocking density, and then set up 20 pairs of male and female adults of S. spp. Pairs of male and female adults of Damen wax armor. According to the 8-day e...

Embodiment 2

[0070] Embodiment 2 Raising of larvae

[0071] The room temperature is 19°C and the humidity is 75%.

[0072] Continue embodiment 1 to carry out follow-up larva rearing, after the eggs hatch into small larvae, put into 4 Tenebrio molitor pupae in the box every day, change fresh feed every day, allow it to get food Tenebrio molitor pupae to 2 instars in the circular culture box.

[0073] Then they were removed and raised in polystyrene cuboid boxes (length×width×height=18cm×10cm×4cm) with sawdust. The sawdust is placed at a height 8 mm from the top of the inner edge of the box. The larvae of 5 circular culture boxes are put into each cuboid box, and fresh feed is changed every day.

[0074] Counting from the egg hatching, 20-22 days later, the larvae mature.

Embodiment 3

[0075] Example 3 Larval pupation and eclosion

[0076] The room temperature is 19°C and the humidity is 75%.

[0077] Continue to embodiment 2 to carry out pupation and eclosion. The pupation sand is sterilized at 150°C for 2 hours, then wetted with sterilized water, and left for 1 day before being used for pupation.

[0078] Cover the pupation sand in the eclosion box (cuboid box: length×width×height=18cm×10cm×4cm; polystyrene material).

[0079] After the mature larvae were put into the eclosion box for 40-50 days, the eclosion adults crawled out of the sandbox.

Abstract

Dendroctonus valens is one of important injurious forest-insects invading China, harms various pinus trees, dragon spruce, Douglas firs, firs, dahurian larches and the like within the distribution range of the dendroctonus valens and is characterized by being hidden in harm, large in propagation quantity and not prone to be found, and physical control and chemical control are difficult.The natural enemy of dendroctonus valens, namely, rhizophagus grandis is used for controlling the harm of the dendroctonus valens, and important practical significance is achieved in production.Through indoor artificial propagation studies of the rhizophagus grandis, a set of effective rhizophagus grandis production process is formed, and the efficiency of artificial reproduction of the rhizophagus grandis is improved.

Description

technical field [0001] The invention relates to a method for artificially propagating chinensis, which belongs to the biological control technology of forestry insect pests. Background technique [0002] The red beetle (Dendroctonus valens LeConte) (Coleoptera: Scolytidae) is native to North America such as the United States and Canada, and is one of the important forest pests invading my country. As a secondary pest, it almost harms all kinds of Pinus spp. species, spruce (Picea), yellow fir (Pseudotsuga), fir (Abies) and larch (Larix) within its distribution range. [0003] According to the Pest Risk Analysis (PRA) method, the red beetle is a highly dangerous forest pest in China. 526,000 hm in my country 2 Pinus tabulaeformis (Pinustabulaeformis) occurred seriously, killing 35 million pinus tabulaeformis and losing 2.5 billion yuan. It has become the second killer of forests in my country. [0004] The damage characteristic of the red beetle is its hidden life. Most of...
