柑桔黄龙病是危害柑桔作物的一种严重病害，柑桔霉是黄龙病病原菌的载体。由于HLB没有已知的控制方法，通过部署半化学物质来操纵昆虫的行为为保护柑橘作物提供了一个有希望的机会。研究了柑桔对植物挥发物的行为反应，以及这些植物挥发物的特性。分别从寄主植物牡丹、柑桔、芦笋、芦笋、三叶蓬等植物和非寄主植物番石榴、芒果、西洋桃等植物中提取挥发物。在行为分析中，雌性柑橘大鼠在含有泛泛性支原体挥发物或中华支原体挥发物的组中比对照组待的时间更长。当柑桔暴露于从西花楸中收集的挥发物时，它们更倾向于对照组。其他植物释放的挥发物对柑橘的觅食行为没有影响。对三种植物的挥发物进行化学分析，发现西花楸中含有较多的萜类化合物(E)-4,8-二甲基三烯-1,3,7 -三烯（DMNT）和（E，E）-4,8,12-三甲基三烯-1,3,7,11-四烯（TMTT）。在进一步的行为生物测定中，与对照组相比，雌性柑橘鼠在含有DMNT和TMTT合成混合物的组中待的时间更短。与对照组相比，雌性柑橘大鼠在含有合成混合物的对照组中花费的时间也更短，这些混合物中含有从paniculata或C. sinensis中提取的挥发性提取物。结果表明，这两种萜类化合物的高释放量使该物种对柑橘螟没有吸引力，这两种萜类化合物可用于减少柑橘植株的定殖，从而减少HLB感染。
Diaphorina citri is a vector of the bacterial causative agent of Huanglongbing (HLB = Citrus greening), a severe disease affecting citrus crops. As there is no known control for HLB, manipulating insect behaviour through deployment of semiochemicals offers a promising opportunity for protecting citrus crops. The behavioural responses of D. citri to plant volatiles, and the identity of these plant volatiles were investigated. Volatiles were collected from host plants Murraya paniculata, Citrus sinensis, C. reshni, C. limettioides, Poncirus trifoliata, and from non-host plants Psidium guajava, Mangifera indica, Anacardium occidentale. In behavioural assays, female D. citri spent more time in the arms containing volatiles from either M. paniculata or C. sinensis compared to the control arms. When D. citri was exposed to volatiles collected from A. occidentale, they preferred the control arm. Volatiles emitted from the other studied plants did not influence the foraging behaviour of D. citri. Chemical analyses of volatile extracts from C. sinensis, M. paniculata, and A. occidentale revealed the presence of the terpenoids (E)-4,8-dimethylnona-1,3,7–triene (DMNT) and (E,E)-4,8,12-trimethyltrideca-1,3,7,11-tetraene (TMTT) in higher amounts in A. occidentale. In further behavioural bioassays, female D. citri spent less time in arms containing a synthetic blend of DMNT and TMTT compared to the control arms. Female D. citri also spent less time in arms containing the synthetic blend in combination with volatile extracts from either M. paniculata or C. sinensis compared to the control arms. Results suggest that higher release of the two terpenoids by A. occidentale make this species unattractive to D. citri, and that the terpenoids could be used in reducing colonisation of citrus plants and therefore HLB infection.
