- Abstract:
- ?Sex lures trapping method was used to investigate the occurring period of L.glycinivorella in Heihe region from 2009 to 2012.The results showed that L.glycinivorella occurred in the middle of July and ended in mid-August,lasting about 30 days.The occurrence of L.glycinivorella showed multiple peaks,and the main peak generally appeared in the July 23-29.In 2011,the peak delayed about 10 days due to climate.In 20092012 the insect feed rate of? L.glycinivorella in Heihe area was 5.53%-11.26%,belonging to mild to moderate damage.
