摘要: 福建橄榄瘿螨Fujianacaricalus albumus sp.nov.主要为害橄榄新梢和嫩叶, 造成叶片变褐、变硬、枯萎脱落。该螨背盾板、背瘤及足基节与橄榄裂柄瘿螨存在明显区别, 为橄榄上发现的另一种瘿螨。调查结果表明, 在福州地区福建橄榄瘿螨发生时期与气温及橄榄梢萌发时间有关, 世代重叠现象明显。一年中以春梢受害最为严重, 其次为秋梢。本文针对福建橄榄瘿螨的发生规律, 提出防治建议。Abstract: The majority of new eriophyid mite (Fujianacaricalus albumus sp.nov.) damage the twigs.In the spring and autumn, the twigs were damaged seriously.At the first stage, the buds become redness.At the second stage, the tender leaves curved and become dark.In the following stages, the whole twigs become brown and dried.The significant differences between F.albumus sp.nov.and Dichopelmus canarii Kuang, Xu et Zeng, sp.nov.are shown in the shield、lateral microtubercles and coxae.The investigation result showed that the occurrence periods of F.albumus sp.nov.were related with the temperature and sprouting time of new shoots of Chinese olive.Besides, Based on the occurrence regularity of F.albumus sp.nov.in Fuzhou, concerning control suggestions were given.
