Abstract

Abstract:

The effect of high voltage pulse current on the vitality and reproduction of pine wood nematode was investigated. The results showed that highvoltage pulse current could kill pine wood nematode and inhibit the migration and diffusion capacity of pine wood nematode，the wider the pulse width and the more number pulse and the shorter electric treatment interval，the better the effect of high voltage pulse current on the vitality of pine wood nematode，the main impact factors were pulse width and electric treatment interval; high voltage pulse current could inhibit the reproduction capacity of pine wood nematode，the wider the pulse width and the longer treatment time，the better the effect of high voltage pulse current on the reproduction of pine wood nematode. The reaction of different instars of pine wood nematode to high voltage pulse current were different，the adult was more resistant to high voltage pulse current than the larvae，especially the female.

Key words: high voltage pulse current, pine wood nematode ( Bursaphelenchus xylophilus), vitality, reproduction
