| 柑橘木虱 Diaphorina citri Kuwayama 是传播柑橘黄龙病 Citrus huanglongbing（HLB）的主要昆虫媒介，通常认为柑橘木虱寄主为芸香科植物。生草栽培技术是一种优良的农业栽培管理技术，旋花科植物甘薯 Ipomoea batatas 和豆科植物广金钱草 Desmodium styracifolium 近年来被间作于柑橘园。为评价这两种植物对柑橘木虱防控的影响，本文从柑橘木虱寄主选择、存活、取食行为和产卵 4 个方面检测柑橘木虱在甘薯和广金钱草上的适生性。在寄主选择试验中，与芸香科植物九里香 Murraya paniculata (L .)Jack 相比，柑橘木虱成虫选择甘薯（18.99% vs 72.96%）或广金钱草（2.05% vs 83.49%）的比率均显著较低。柑橘木虱成虫在甘薯和广金钱草上最长存活时间分别为 12 d 和 11 d，存活时间无显著差异，但是均显著短于在九里香上的最长存活时间（观察至20 d），长于仅提供水的处理（9 d）和饥饿处理（4 d）。刺探电位图谱技术发现，柑橘木虱在这两种非芸香科植物上均存在取食木质部的波形，没有分泌唾液或取食韧皮部的波形，而在九里香上这些波形均存在。此外，柑橘木虱均不在这两种非芸香科植物上产卵。结果表明，柑橘木虱可选择这甘薯和广金钱草并取食其木质部获得短时间存活，因此甘薯和广金钱草可为柑橘木虱提供过渡食物和暂时栖息环境，在柑橘园种植时需要谨慎考虑。 |

| Diaphorina citri Kuwayama is the main insect vector of citrus huanglongbing. It is an oligophagous insect with a host range restricted to plants in the Rutaceae family. Cover crop is an excellent agricultural cultivation and management technique. In recent years, the Convolvulaceae plant Ipomoea batatas and the leguminous plant Desmodium styracifolium has been intercropped in citrus orchards. To evaluate the effect of these two plants on management of D. citri, we analyzed the adaptability of D. citri on I. batatas and D. styracifolium from the aspects of host preference, survival duration, feeding behaviour, and oviposition. Results showed that D. citri showed preference of Murraya paniculata (Rutaceae) when compared with I. batatas (select rate 18.99% vs 72.96%) or D. styracifolium (select rate 2.05% vs 83.49%). The longest survival duration of D. citri adult on I. batatas and D. styracifolium were 12 d and 11 d, respectively. The duration did not differ between the two non-rutaceous plants, but was significantly shorter than that on M. paniculata (more than 20 d), and longer than the treatment provided with water (9 d) and starvation (4 d). For the feeding behavior experiment, when feeding on the two non-rutaceous plants, D. citri had xylem feeding waveform, but did not has salivation or phloem feeding waveform, while all of these waveforms were observed when feeding on M. paniculata. In addition, D. citri did not lay eggs on I. batatas or D. styracifolium. These results indicate that D. citri has the ability to select I. batatas and D. styracifolium and ingest xylem to survive. Therefore, I. batatas and D. styracifolium can provide transitional food and temporary habitat for citrus psyllids, and should be carefully considered when planting in citrus orchards. |
