Oviposition by the leafhopperAmrasca devastans (Distant) on its susceptible host plant, cotton (Gossypium hirsutum var. PS-10), was inhibited by the volatiles of certain plants and by the vapors of some chemicals occurring in various plants when these were presented at a distance from the ovipositional substrate. The effectiveness of the volatiles of the plants for inhibiting the oviposition decreased in the order: eucalyptus > coriander=castor=tomato > lime,Ocimum being without effect. Among the volatile plant chemicals tested, the inhibitory effects decreased in the order: citral=carvacrol > citronellol=farnesol = geraniol=eucalyptus oil > neem oil=Cymbopogan oil. These chemicals served as volatile antiovipositants and did not reduce the arrival/stay of the insects on the host plants. Carvacrol had a slight toxic effect on the nymphs, but none of the volatiles was toxic to the adults.
棉叶蝉（Amrasca devastans （Distant））在其易感性宿主植物棉花（Gossypium hirsutum var. PS-10）上产卵时，会受到某些植物挥发物和某些植物中化学物质蒸气的抑制，这些化学物质在远离产卵基质的地方被呈现出来。植物挥发物抑制产卵的效果依次为：桉树>香菜=蓖麻=番茄>酸橙，而奥图姆（Ocimum）则没有效果。在所测试的挥发性植物化学物质中，抑制效果依次为：柠檬醛=香芹酚>香茅醇=法呢醇=香叶醇=桉树油>印楝油>Cymbopogan 油。这些化学物质作为挥发性抗产卵剂，不会减少昆虫在宿主植物上的到达/停留。香芹酚对若虫有轻微的毒性作用，但没有一种挥发物对成虫有毒。
