摘要。研究了胡萝卜蝇幼虫对寄主植物挥发物的反应。定向反应使用了两个标准：一个基于个体是否到达气味源1.5厘米内，另一个涉及分析气味源3厘米内幼虫的轨迹模式。所有的幼虫都被寄主和非寄主植物材料所吸引，尽管后者的吸引程度较低；它们也会被CO2吸引，但不会被N2吸引。胡萝卜根的蒸汽挥发分及其挥发分之一甲基丁香酚对幼虫也有不同浓度的吸引作用。讨论了CO2和寄主次生植物挥发物在土壤节肢动物寻找寄主行为中的可能作用。
ABSTRACT. The responses of carrot fly larvae, Psila rosae, to host plant volatiles were studied. Two criteria for an oriented response were used: one based on whether an individual reached within 1.5 cm of the odour source and one involving analysis of the track patterns of larvae within 3 cm of the odour source. All larval instars were attracted to both host and non‐host plant material, though to a lesser degree by the latter; they were also attracted to CO2, but not to N2. A steam volatile fraction of carrot roots, and methyl eugenol, a volatile component of this fraction, also attracted the larvae, differentially at different concentrations. The possible roles of both CO2 and the host‐specific secondary plant volatiles in the host plant finding behaviour of soil inhabiting arthropods are discussed.
