Analyses and Control of Increased Damage of Wire Worm in Zhengzhou

As one of the major destructive soil-inhabiting insect pests in Zhengzhou,Henan province,China,the population density of wire worm has increased in recent years with serious damage locally,which causes sprout deficiency of wheat and maize.Analyses indicated that warming climate in winter and spring,abundant food,increasing areas of composting of crop straws,forbidding or limiting of highly-toxic and severe toxic pesticides,and reduction of soil treatment area were main reasons leading to the increasing damage of wire worm in recent years.On the basis of forecasting and agricultural control,the comprehensive strategies including priority utilization of physical and biological control technologies,and scientific usage of chemical control technology were proposed for control of wire worm.
