摘要

大叶夹竹桃树皮鳞(CMBS),Acanthococcus lagerstroemiae (Kuwana) (Hemiptera: Eriococcidae),是一种非本地鳞翅目昆虫,自 2004 年在得克萨斯州达拉斯附近首次发现后,已遍布美国东南部和中大西洋地区的许多城市地区,严重降低了广受欢迎的观赏性大叶夹竹桃树(Lagerstroemia spp.)的美学价值和健康状况。我们用已知数量的 CMBS 侵染夹竹桃,以确定其最初到达植物后建立族群所需的最低个体数量。我们还研究了网捕是如何影响种群增长的,实施网捕的目的是为了了解当鳞片扩散和捕食受到抑制时种群建立的差异。我们发现,在 92% 的情况下,一个雌性 CMBS 卵囊可以成功建立一个新种群,而网捕对种群建立的影响可以忽略不计。我们的研究结果表明,在试图防止苗木受侵染时,调查和管理具有类似生物学特性的 CMBS 和鳞翅目昆虫非常重要,因为苗木被广泛认为是鳞翅目昆虫远距离传播的媒介。

Plant-level establishment can result from a single female Acanthococcus lagerstroemiae propagule

Crapemyrtle bark scale (CMBS), Acanthococcus lagerstroemiae (Kuwana) (Hemiptera: Eriococcidae), is a non-native scale insect that has spread throughout many urban areas of the Southeast and Middle Atlantic regions of the United States following its initial detection near Dallas, Texas in 2004, severely reducing the aesthetic value and health of the popular ornamental crapemyrtle tree (Lagerstroemia spp.). We infested crapemyrtles with known numbers of CMBS to determine the minimum number of individuals required for establishment after initial arrival on plants. We also investigated how netting—implemented to understand differences in establishment when scale dispersal and predation are inhibited—influenced population growth. We determined that one female CMBS egg sac can successfully establish a new population ~ 92% of the time and that netting had negligible effects on establishment. Our results underscore the importance of surveying and managing CMBS and scale insects with similar biology when attempting to prevent infestation of nursery stock, which is widely implicated as a vector for long-distance dispersal of scale insects.

期刊介绍: Journal of Pest Science publishes high-quality papers on all aspects of pest science in agriculture, horticulture (including viticulture), forestry, urban pests, and stored products research, including health and safety issues. Journal of Pest Science reports on advances in control of pests and animal vectors of diseases, the biology, ethology and ecology of pests and their antagonists, and the use of other beneficial organisms in pest control. The journal covers all noxious or damaging groups of animals, including arthropods, nematodes, molluscs, and vertebrates. Journal of Pest Science devotes special attention to emerging and innovative pest control strategies, including the side effects of such approaches on non-target organisms, for example natural enemies and pollinators, and the implementation of these strategies in integrated pest management. Journal of Pest Science also publishes papers on the management of agro- and forest ecosystems where this is relevant to pest control. Papers on important methodological developments relevant for pest control will be considered as well.
