Embodiment 1

[0021] 1. Test method: (test repeated three times)

[0022] (1) Put the male bee pupae of Bombus hypocrita into the finger tube, then insert the mated Sclerodomina chrysalis female bee, plug the finger tube mouth tightly with absorbent cotton, The quantity ratio of Scleroderma bovis and the pupae of Bombus bumblebee and drone is 1: 3;

[0023] (2) Put finger tube in 26.5 ℃, in the artificial climate box of relative humidity 68%, cultivate 15 days; Then adjust the temperature in the artificial climate box to 25 ℃, relative humidity 75%, cultivate 23 days, pine brown The swollen-legged beetle begins to emerge, and the swollen-legged wasp after the emergence is taken out from the artificial climate box, placed at room temperature for 2 days, then selected and reserved;

[0024] (3) select 15 white plastic boxes of 40cm * 30cm * 20cm for use, all put into 6 sections to be connected with the masson pine wood section that monochamus larvae (1-3 instars) are connected in every box, ...

Abstract

The invention discloses a method by the adoption of biological control. According to the method, the populations of the monochamus alternatus of pine forests are obviously reduced and controlled, and the number of pines which die from bursaphelenchus xylophilus is also obviously reduced. Drone pupae of bombus hypocrita are adopted as hosts of sclerodermus sp., meanwhile proliferation conditions are regulated and controlled, and therefore the parasitic ability of the sclerodermus sp. obtained through proliferation is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of forest protection, in particular to a method for comprehensively controlling Monochamus alternatus (Monochamus alternatus) and effectively controlling pine wood nematode (Bursaphelenchus xylophilus) mainly through biological measures. Background technique [0002] Pine wood nematode disease is called the "cancer" of pine trees. It is the most serious forest pest in China at present, and it poses a major threat to the ecological environment construction dominated by forestry in my country. At present, pine wood nematode disease has occurred in 200 county-level administrative regions of 16 provinces (autonomous regions and municipalities) in my country, as well as Hong Kong and Taiwan. Because pine wood nematode has the characteristics of rapid transmission, strong fecundity, and fast death of trees, pine trees can die within 40 days at the earliest after being infected with pine wood nematode, and pine for...
