Every year, solanaceous crops, such as potato (Solanum tuberosum) and tomato (Solanum lycopersicum), suffer important economic loss due to insect pests and the diseases they transmit. While pesticides can be used to control insects directly, they can exacerbate some vector-borne diseases by increasing insect movement among plants and thus increase disease transmission. The purpose of this study was to evaluate the use of aminoethoxyvinylglycine (AVG), an inhibitor of ethylene biosynthesis, as a potential control strategy for insect vectors and vector-borne disease of tomato and potato. AVG application (0.5 g/L) was evaluated in field plots and insect populations were monitored. Two field applications of AVG reduced total insect and leafhopper populations in tomato and potato plots, however, AVG increased thrips populations in tomato fields later in the growing season. Dual-choice bioassays were performed to examine the effect of AVG on insect preference toward virus-infected plants. AVG application reduced aphid preference to Potato leafroll virus infected potato plants but did not affect leafhopper preference to Beet curly top virus infected tomato plants. Taken together, these results suggest that AVG has the potential to be used as a component of integrated management practices, but additional studies will be required.

每年都有茄类作物，例如马铃薯（Solaum tuberosum）和番茄（Solanum lycopersicum）。），由于虫害及其传播的疾病而遭受重大的经济损失。尽管农药可直接用于控制昆虫，但它们可通过增加植物间的昆虫移动而加剧某些病媒传播的疾病，从而增加疾病的传播。这项研究的目的是评估使用氨基乙氧基乙烯基甘氨酸（AVG）（一种乙烯生物合成抑制剂）作为昆虫媒介和媒介传播的番茄和马铃薯疾病的潜在控制策略。在田间田地评估了AVG的施用量（0.5 g / L），并监测了昆虫种群。AVG的两次田间施用减少了番茄和马铃薯地块的总昆虫和叶蝉种群，但是，AVG在生长季节后期增加了番茄田的蓟马种群。进行了双重选择生物测定，以检验AVG对昆虫偏爱病毒感染植物的影响。AVG应用程序降低了蚜虫对马铃薯卷叶病毒感染马铃薯植株，但不影响叶蝉对甜菜卷曲顶病毒感染的番茄植株的偏爱。综上所述，这些结果表明AVG有可能被用作集成管理实践的组成部分，但是还需要进行其他研究。
