Abstract

ABSTRACT: Laboratory experiments were conducted to determine larval movement of the spotted wing drosophila (Drosophila suzukii Matsumura). Movement of larvae outside of the wild blueberry fruit (Vaccinium angustifolium Aiton) can occur after exhausting fruit food resources pri- or to completion of development or just prior to pupation. We found that when provided a choice larvae select moist compared to dry environments both in plastic arenas providing only filter paper for shelter and in a soil filled petri dishes. Movement was usually limited to less than 7.5 cm in the soil from a release point. An exponential decay model suggests that only 0.1% of a larval population will move as far as 17.5 cm. Results of our study suggest that while larvae move readily, they have minimal ability to avoid localized xeric soil micro-climatic conditions through movement. However, they will select less stressful moist soil environments.

摘要/ ABSTRACT摘要:对斑点翅果蝇(drosophila suzukii Matsumura)的幼虫运动进行了实验研究。野生蓝莓(Vaccinium angustifolium Aiton)的幼虫可以在果实食物资源耗尽或发育完成或化蛹之前在果实外运动。我们发现,当提供选择时,幼虫选择潮湿的环境,而不是干燥的环境,无论是在仅提供滤纸作为庇护的塑料竞技场还是在充满土壤的培养皿中。从释放点到土壤的移动通常被限制在7.5厘米以内。一个指数衰减模型表明,只有0.1%的幼虫种群会移动17.5厘米。我们的研究结果表明,虽然幼虫很容易移动,但它们通过移动来避免局部干旱土壤小气候条件的能力很小。然而,它们会选择压力较小的潮湿土壤环境。
