Abstract

Aphis craccivora Koch and Planococcus lilacinus Cockerell are phloem feeders and act as vectors for transmitting plant viruses to agricultural and horticultural crops thereby damaging them. The persistent and widespread use of synthetic, wide-spectrum pesticides has resulted in resistance development that is detrimental to the environment, human health, and natural enemies of pests. The present investigation uses various extraction mediums to examine the insecticidal efficacy of essential oils (EOs) isolated from Murraya koenigii (L.) leaves. Increase in yield was observed in the EO extracted using NADES-AHD [0.16% (obtained with hydro-distillation)] to 0.30% [obtained with N-1 (glycerol:lactic acid)]. EO obtained with water was found more effective against A. craccivora (LD50 = 0.89 µL/insect) and followed by N-1 (glycerol:lactic acid), and N-3 (choline chloride:citric acid) (LD50 = 1.29-1.38 µL/insect). Similarly, EO isolated by water and N-4 (choline chloride:oxalic acid) was effective against P. lilacinus (LD50 = 2.63-3.06 µL/insect). Additionally, the EO prepared by water substantially reduced glutathione S-transferase (GST) and acetylcholinesterase (AChE) in target pests, suggesting that these enzymes may be the EOs' site of action. NADES-AHD has enhanced the EO yield as compared to the conventional method. The EO obtained with water showed promising toxicity against target pests and target site of action. Therefore, based on field and greenhouse bio-efficacy experiments, EOs/biopesticides/botanicals can be proposed for controlling the spread of mealy bugs and aphids.

用天然深层共晶溶剂获得的 Murraya koenigii(L.)精油的化学成分和杀虫潜力。
Aphis craccivora Koch 和 Planococcus lilacinus Cockerell 以韧皮部为食,是向农作物和园艺作物传播植物病毒的媒介,从而对农作物和园艺作物造成损害。合成广谱杀虫剂的持续和广泛使用导致了抗药性的产生,对环境、人类健康和害虫的天敌造成了损害。本研究使用各种提取介质来检测从 Murraya koenigii(L.)叶片中分离出来的精油(EOs)的杀虫功效。在使用 NADES-AHD 提取的精油中观察到产量增加[0.16%(使用水蒸馏法提取)]至 0.30%[使用 N-1(甘油:乳酸)提取]。发现用水提取的环氧乙烷对 A. craccivora 更有效(LD50 = 0.89 µL/只昆虫),其次是 N-1(甘油:乳酸)和 N-3(氯化胆碱:柠檬酸)(LD50 = 1.29-1.38 µL/只昆虫)。同样,由水和 N-4(氯化胆碱:草酸)分离出来的环氧乙烷对 P. lilacinus 有效(LD50 = 2.63-3.06 µL/昆虫)。此外,用水制备的环氧乙烷能显著降低目标害虫体内的谷胱甘肽 S-转移酶(GST)和乙酰胆碱酯酶(AChE),这表明这些酶可能是环氧乙烷的作用部位。与传统方法相比,NADES-AHD 提高了环氧乙烷的产量。用水获得的环氧乙烷对目标害虫和目标作用点的毒性表现良好。因此,根据田间和温室生物功效实验,可以建议使用环氧乙烷/生物农药/植物药来控制蚧壳虫和蚜虫的传播。
