Comprehensive Prevention and Control Experiment of Hyphantria cunea in Dongping County
According to the experimental results and analysis,the effects and advantages and disadvantages of four comprehensive control methods of Hyphantria cunea were compared.Aircraft spraying,ground spraying and air-craft spraying combined with ground drug control all showed good control effect,which could effectively control the number of Hyphantria cunea.The average number of target trees per plant was between 10.6 and 11.8.Among them,aircraft spraying has the characteristics of wide coverage and remarkable effect,which is suitable for large-scale prevention and control;the effect of aircraft spraying combined with ground control is basically the same;ground spraying is suitable for the prevention and control of small areas and can be concentrated in the target are-a.The trapping effect of the pest-killing lamp was relatively poor and had little impact on the environment,but the control of the number of Hyphantria cunea may be limited.Aircraft spraying is the most effective and reliable method to control Hyphantria cunea.Choosing the appropriate control method according to the actual situation,combined with other comprehensive management measures,such as biological control,can better control the num-ber of Hyphantria cunea.
