摘要
The results of evaluation on field control efficacy of Trichogramma dendrolimi against Ostrinia furnacalis showed that the correction rates of Ostrinia furnacalis egg mass parasitism were 71.75% and 73.57%,the average control effect were 65.85% and 70.24%,the restoration yield loss rates were 6.78% and 7.97%,input-output ratio at 1:27.8 and 1:33.5 in Longjiang county of Heilongjiang province in 2009 and 2010,respectively.The technology is a integration of advanced,practical,environmental safety,effective biocontrol measures,embodies the "public plant protection,green plant protection" fully,has significant economic,social and ecological benefits.
The results of evaluation on field control efficacy of Trichogramma dendrolimi against Ostrinia furnacalis showed that the correction rates of Ostrinia furnacalis egg mass parasitism were 71.75% and 73.57% , the average control effect were 65.85% and 70. 24% , the restoration yield loss rates were 6.78% and 7.97% , input - output ratio at 1 : 27.8 and 1 : 33.5 in Longjiang county of Heilongjiang province in 2009 and 2010, respectively. The technology is a integration of advanced, practical, envi- ronmental safety, effective biocontrol measures, embodies the "public plant protection, green plant pro- tection" fully, has significant economic, social and ecological benefits.
