specific Embodiment approach 1

[0033] Embodiment 1: The cultivation method of the Korean pine borer wasp in this embodiment includes the following steps:

[0034] 1, bee seed collection and preservation: collecting and identifying bee seeds in pupal stage of the fruit-tip borer, and preserving at low temperature;

[0035]Step 2, reproduction of bee species: taking out the low-temperature preserved Rhinophylla koraiensis, inoculating 2-30 Rhinophylla koraiensis into each host pupa, and putting the host pupa parasitized by Rhinophylla koraiensis into a constant temperature box or a greenhouse for cultivation.

[0036] In the second step, before receiving bees, the host pupa is soaked in hypochlorous acid aqueous solution with a concentration of ≤ 25%, then taken out, washed with distilled water and dried.

[0037] The functional relationship curve between the development duration and temperature of the red-tip borer is as follows Figure 1 Shown.

[0038] Hypochloric acid can soften the cuticle of pupae, especiall...

specific Embodiment approach 2

[0040] Embodiment 2: The difference between this embodiment and Embodiment 1 is: in Step 2, the effective accumulated temperature for breeding the stichopus koraiensis is 1-3 days of female bee day, and the humidity is 50-75%. Other steps and parameters are the same as the first embodiment.

[0041] Table 1 shows the starting temperature and effective accumulated temperature of the development of Rhinophylla koraiensis (with Rhinophylla koraiensis as the host).

[0043]

specific Embodiment approach 3

[0044] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that in Step 2, the biting wasp of the fruit-tip borer is a female bee that emerged on the same day or 1-2 days after emergence. Other steps and parameters are the same as those of Embodiment 1 or 2.

Abstract

The invention discloses an application of cultivating the red pine moth wasp in the prevention and treatment of the red pine moth, and provides a method for large-scale propagation of the red pine leaf red bee, which relates to the technical field of forestry protection; the purpose is To carry out effective biological control of fruit spot borer and other coniferous tree seeds and branch pests, the propagation method is as follows: step 1, collection and preservation of bee species; step 2, reproduction of bee species; soaking the host in hypochlorous acid aqueous solution , and gradient cooling preservation improved the parasitic ability of the red pine moth.

Description

Technical field [0001] The invention relates to the technical field of forestry protection, in particular to the prevention and control of the fruit borer, and a large-scale propagation method of the red pine borer in the prevention and control of the fruit borer. technical background [0002] Pinus koraiensis, an evergreen tree of Pinaceae, is not only a precious timber tree, but also a dominant tree species of natural forests in Xiaoxing 'an Mountains and Changbai Mountains in Northeast China, and one of the main afforestation tree species in Northeast China. At the same time, Korean pine seeds are rich in oil and protein. Because of their high nutritional and health value, they are deeply loved by consumers at home and abroad, and they are important economic resources in northeast forest areas. In recent years, the rising price of pine seeds has made Korean pine economic forest one of the important ways for people in forest areas to get rich, and it is also one of the importan...
