摘  要:
菠萝粉蚧刺吸寄主汁液,分泌的蜜露容易引起霉烟病,是菠萝凋萎病病毒的主要传播媒介,是菠萝的一种重要害虫。采用隔行跳跃式及定点调查分别对雷州半岛菠萝粉蚧大田空间分布、自然种群消长动态进行调查。结果表明:菠萝粉蚧在菠萝中自然种群消长曲线呈单峰型,其空间格局是以个体群为基本成份呈聚集分布。

摘  要:
Dysmicoccus brevipes is one of the most serious pests in pineapple(Ananas comosns L.Merr.),for its sucking juice from plant and vectors’ status of Mealybug wilt of pineapple(MWP).The dynamics and spatial distribution pattern of population of Dysmicoccus brevipes(Cockerell) were be investigated by settled or random sampling.The spatial distribution pattern of population of Dysmicoccus brevipes is aggregation distribution,and the fastigium of the t is natural population is visible between to the first ten-day December to the last ten-day of January.
