Embodiment 1

[0023] 1. Test method: (test repeated three times)

[0024] (1) Place the larvae cocoons of the pine stem borer parasitized by the long-bodied wasp in a test tube, place the test tube in an artificial climate box, keep the temperature at 28°C, and keep the humidity at 75%, and cultivate at a constant temperature Until the eruption of the long-bodied wasp Watanabe, 400 healthy bees A were screened, and the male-to-female ratio was 1:1;

[0025] (2) Take the old masson pine branches of the year, cut the branches into two halves with a knife, carve a groove in the middle of the cut branches, engrave a small hole on the edge of the groove to simulate the larva holes of the damaged branches, and place the reddish tip borer 3 Place the instar larvae in the carved groove, put two pine branches together, tie them tightly with rubber bands, dip into the paraffin solution for 1 second, and then take them out; after the paraffin wax cools, cut the paraffin at the small hole on the branch...

Abstract

The invention discloses a large-scale propagation expanding method for Macrocentrus watanabei. By improving the propagation expanding temperature of the Macrocentrus watanabei and exercising bee species, the manual large-scale propagation expansion of the Macrocentrus watanabei is realized, and the degeneration problem of the bee species is solved.

Description

technical field [0001] The invention relates to the technical field of forestry protection, in particular to a method for large-scale propagation of the long-bodied wasps Watanabe. 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 pine economic forest one of the important ways for people in forest areas to get rich, and it is also one of the important dri...
