Association of non-host crop plants with mandarin on host location and survival of Diaphorina citri Kuwayama (Hemiptera: Liviidae)

Control of the Asian citrus psyllid (ACP) Diaphorina citri, vector of the causal agent of citrus Huanglongbing (HLB), is important to avoid the spread of the most devastating citrus disease worldwide. However, because ACP management has been difficult, research efforts have been made to develop novel tactics, such as those targeting behavioral control. Here, we investigated whether association of ‘Ponkan’ mandarin (Citrus reticulata) with volatiles of the non-host crop plants: ‘Fortuna’ avocado (Persea americana), passion fruit ‘Maracuja azedo’ (Passiflora edulis) or coffee (Coffea arabica), alter host location by the ACP; and whether these crops can be temporary hosts for the ACP亚洲柑橘木虱（Asian citrus psyllid, ACP，学名：Diaphorina citri）是柑橘黄龙病（citrus Huanglongbing, HLB）致病菌的传播媒介，防控该虫对遏制这一全球范围内危害最严重的柑橘病害扩散至关重要。然而，由于亚洲柑橘木虱的防治难度较高，科研人员已致力于开发新型防控策略，例如基于行为调控的防治手段。本研究探究了以下两项内容：一是将椪柑（Citrus reticulata）与非寄主作物挥发物联用——包括“富尔图纳”鳄梨（Persea americana）、“酸马拉库亚”百香果（Maracuja azedo，Passiflora edulis）以及阿拉伯咖啡（Coffea arabica）——是否会干扰亚洲柑橘木虱的寄主定位行为；二是上述作物能否作为该木虱的临时寄主。
