Plant-derived compounds are sources of biopesticides for the control of insect pests. We compared the growth performance and enzymatic response of the grasshopper Calliptamus abbreviatus Ikonn to six plant-derived compounds (rutin, quercetin, nicotine, matrine, azadirachtin, and rotenone) in laboratory and field trials. When exposed to the six compounds, C. abbreviatus had significantly reduced growth and survival. All the compounds significantly induced an elevated level of reactive oxygen species, indicating oxidative damage. The activity of detoxifying enzymes, including cytochrome P450s, carboxylesterase, glutathione-S-transferase, and UDP-glucuronosyltransferase, and the antioxidant enzymes, including superoxide dismutase, catalase, and peroxidase, all significantly increased after exposure to the six compounds. These data suggest that the six plant-derived compounds had negative effects on C. abbreviatus. Of the six compounds, matrine, azadirachtin, and rotenone were more toxic to C. abbreviatus, followed by nicotine, quercetin, and rutin. These results show the potential of these compounds as botanical pesticides, which can be applied for the biological control of the grasshopper C. abbreviatus.

蚱hopper，Calliptamus abbreviatus（直翅目：Ac科）对六种植物衍生化合物的生长性能和酶促反应。

植物来源的化合物是用于控制害虫的生物农药的来源。在实验室和田间试验中，我们比较了蚱CallCalliptamus abbreviatus Ikonn与六种植物来源的化合物（芦丁，槲皮素，尼古丁，苦参碱，印dir素和鱼藤酮）的生长性能和酶促反应。当暴露于六种化合物时，C。abbreviatus的生长和存活率显着降低。所有这些化合物均显着诱导了较高水平的活性氧，表明氧化损伤。排毒酶的活性，包括细胞色素P450，羧酸酯酶，谷胱甘肽S-转移酶和UDP-葡糖醛酸糖基转移酶以及抗氧化剂酶（包括超氧化物歧化酶，过氧化氢酶和过氧化物酶）在接触这六种化合物后均显着增加。这些数据表明，六种植物来源的化合物对阿伯雷德酵母有不利影响。六种化合物，苦参碱，印楝素，鱼藤酮和的更毒性C. abbreviatus，接着尼古丁，槲皮素，芦丁。这些结果表明这些化合物作为植物农药，它们可应用于蚱蜢的生物控制的电位C. abbreviatus。
