荔枝害虫治理现状及展望

目前国内外防治荔枝害虫的手段仍是以化学防治为主体的综合防治。过量使用化学农药造成了荔枝园生态系统的破坏、害虫抗药性增强及再猖獗、果实品质下降及环境污染等一系列严重问题。荔枝害虫治理必将面临一场新的革命;即在系统研究荔枝果园昆虫群落的基础上,以无公害生态调控技术为指导,结合农业防治、生物防治、物理防治、遗传防治及必要的化学防治等多种措施,达到害虫持续控制的目的。

The Present and Future of the Litchi Pest Control

At present, the main method used to control the litchi-pests is the intergrated-pest-management, which applied much of chemical pestcides. Owing to excessive pesticide used , a series of serious problems are produced, for example, the destructive of the ecosystem in the litchi-orchard , the pest anti-chemical and re-rampancy, the decreasing of the fruit quality and the environment pollution , etc . The litchi-pest control must face up to a new revolutionary on policy, which is based on the systematic research on the insect community in the litchi-orchard. The control of the litchi-pests will be hold by the non-harmful ecological control technique, which intergrated many of pest control methods, such as agricultural control, biological control, physical control, genetic control and necessary chemical control.
