Problems solved by technology

While humans are using pesticides to control pests, the resistance of pests is gradually increasing. However, the natural enemies of a large number of pests are killed in large numbers due to their small size and low resistance to pesticides. break out

specific Embodiment approach 1

[0033] Specific embodiment one: the cultivation method of the present embodiment's red pine leaf spot moth nibbler bee comprises the following steps:

[0034] Step 1. Collection and preservation of bee species: collecting and identifying bee species during the pupal stage of S. spp., and storing them under low temperature conditions;

[0035] Step 2. Breeding of bee species: Take out the low-temperature-preserved Korean pine moth wasps by using the finger tube method or the open method, and insert 2 to 30 red pine into each host pupa The wasp is bitten by the spot moth, and the host pupae parasitized by the wasp by the spot moth is put into an incubator or a greenhouse for cultivation.

[0036] Wherein, the second step is to put the host pupa into an aqueous solution of hypochlorous acid with a concentration of ≤25% and soak it before picking up the bees, then take it out, rinse it with distilled water, and dry it.

[0037] The function relationship curve between the developm...

specific Embodiment approach 2

[0040] Specific embodiment two: the difference between this embodiment and specific embodiment one is: in step two, the effective accumulated temperature of breeding the red pine leaf spot moth wasp is 1 to 3 days of female bee days, and the humidity is 50 to 75 %. Other steps and parameters are the same as those in Embodiment 1.

[0041] Table 1 shows the developmental starting point temperature and effective accumulated temperature of the red pine moth gnat (with the fruit moth as the host).

[0043]

specific Embodiment approach 3

[0044] Specific embodiment 3: The difference between this embodiment and specific embodiment 1 or 2 is that in step 2, the wasp is a female bee that emerges on the same day or 1 to 2 days after eclosion. Other steps and parameters are the same as those in Embodiment 1 or 2.

Abstract

The invention discloses application of dioryctria rubellatetrastichus schoenobii ferriere cultivation in dioryctria pryeri control, provides a large-scale propagation method for dioryctria rubellatetrastichus schoenobii ferriere, and relates to the technical field of forestry protection. The method aims at applying effective biological control over dioryctria pryeri and other coniferous species seed and branch injurious insects. The propagation method has the steps of 1 bee species collecting and storing and 2 bee species propagation. Hosts are soaked with a hypochlorous acid water solution and are stored in a gradient cooling mode, so that the parasitic ability of the dioryctria rubellatetrastichus schoenobii ferriere is improved.

Description

technical field [0001] The invention relates to the technical field of forestry protection, in particular to the prevention and control of the leaf spot moth, and a method for large-scale propagation of the red pine leaf spot moth, which is used in the prevention and control of the fruit leaf spot moth. Background technique [0002] Red pine (Pinus koraiensis) is an evergreen tree of the genus Pinus in the family Pinaceae. It is not only a precious timber tree species, but also a dominant tree species in the natural forests of the Xiaoxing'an Mountains and Changbai Mountains in Northeast China. It is one of the main tree species for afforestation in Northeast China. At the same time, Korean pine seeds are rich in oil and protein, and are deeply loved by consumers at home and abroad because of their high nutritional and health value. They are important economic resources in the northeast forest region. In recent years, the ever-increasing price of pine nuts has made Korean pi...
