Description

Technical Field

[0001] The utility model relates to the technical field of pine wood biological control, in particular to a device for quickly separating pine wood nematodes. Background Art

[0002] Pine wood nematode, which belongs to the phylum Nematoda, class Nematoda, order Aphelenchus, family Aphelenchus, genus Aphelenchus, the female body length is 0.81mm, the male body length is 0.73mm, the female tail is nearly conical with a round tip; the male tail is like a bird's claw, curved toward the ventral side. Pine wood nematode disease, also known as pine wilt disease, is a devastating insect pest. It is transmitted into pine trees by vector insects such as pine alternating beetles, thus causing pine diseases. After being infected with pine wood nematodes, the needles of pine trees are yellow-brown or reddish-brown, wilting and drooping, and resin secretion stops. Invasion holes or egg-laying marks of beetles can be observed on the trunks. The entire diseased tree dries up and dies, and eventually rots. Therefore, the study of pine wood nematodes has become an important research in the field of biological control.

[0003] After searching, the Chinese patent publication number, CN207336186U, discloses a pine wood nematode separation device, including a sample rack, a funnel, a filtrate collection carrier net, a culture dish, and a constant temperature heating pot.
