悦目金蛛在南丰蜜橘园中人工释放技术的研究

Study on artificially releasing techniques of Argipoe amoena in Nanfeng citrus garden

通过综合采用不同的释放方式,观察各发育阶段悦目金蛛(Argiope amoena L.Koch.)的生物生态学特性,统计分析其在南丰蜜橘园中的扩散速度、发育历期、生命表、种群空间分布及动态变化等情况,结合蛛网结构与捕食适应特征、捕食害虫种类、数量,估测出其在南丰蜜橘园中控虫的基本释放量、最适释放量与补充释放量,并采用景观生态害虫天敌库源等理论和实验预期,推测在南丰橘园中宜采用果园-菇棚半自然释放模式。

According to the observation of biological and ecological characteristics in different growing stages,spread speed,development period,life table and spatial population distribution dynamics of Argiope amoena L.Koch were analysed statistically by different releasing ways synthetically in Nanfeng citrus garden.And based on cobweb structure,predator characteristics and pest species,basic,complementary and optimum quantity of releasing of A.amoena for pest controlling were estimated.The semi-spontaneous orchard-mushroom sheds releasing model in Nanfeng citrus gardens was proposed by experiments anticipation and using the theory of landscape ecology and pest-natural enemy resource pool.
