AbstractOnion oil and its components were tested for their nematicidal activity against the pine wood nematode, Bursaphelenchus xylophilus, with 96-well plate bioassays. Responses varied with test materials and concentration. Good nematicidal activity against male, female and juvenile nematodes of B. xylophilus was achieved with onion oil. The LC50 values of onion oil against male, female and juvenile pine wood nematodes were 17.6, 13.8 and 12.1 μg ml−1, respectively. Analysis by gas chromatography-mass spectrometry led to the identification of four major sulphur compounds: propyl disulphide, propyl trisulphide, methyl propyl disulphide and methyl propyl trisulphide. These four compounds and propyl sulphide and methyl propyl sulphide were tested individually for their nematicidal activities against pine wood nematode. LC50 values of propyl trisulphide and methyl propyl trisulphide against juvenile nematode were 5.0 and 22.9 μg ml−1, respectively. Other sulphur compounds showed weak activity.

AbstractPlant essential oils from 43 plant species were tested for their nematicidal activities against the pine wood nematode, Bursaphelenchus xylophilus. Responses varied with plant material and concentration. Good nematicidal activity against male, female and juvenile nematodes of B. xylophilus was achieved with essential oils of Cinnamomum verum, Leptospermum petersonii, Asiasarum sieboldi, Boswellia carterii, Pimenta racemosa, Cymbopogon citratus, Mentha spicata, clove and garlic. Garlic and cinnamon oils showed the most potent nematicidal activity among the plant essential oils. Analysis by gas chromatography-mass spectrometry led to identification of three major compounds from garlic and two from cinnamon oil. These five compounds from two essential oils were tested individually for their nematicidal activities against the pine wood nematode. Responses varied with compounds and dose. LC50 values of diallyl trisulphide, diallyl disulphide and cinnamyl acetate against juvenile nematode were 2.79, 37.06 and 32.81 μl−1, respectively. The essential oils described herein merit further study as potential nematicides against the pine wood nematode.

AbstractCommercial essential oils from 29 plant species were tested for their nematicidal activity against the pine wood nematode, Bursaphelenchus xylophilus. Good nematicidal activity against B. xylophilus was achieved with essential oils of Gaultheria fragrantissima and Zanthoxylum alatum. GC-MS analysis of the corresponding oils led to the identification of two and ten major compounds, respectively. Four compounds, methyl salicylate, ethyl salicylate, methyl trans-cinnamate and ethyl trans-cinnamate, were tested individually for their nematicidal activities against the pine wood nematode. Methyl and ethyl salicylates showed strong nematicidal activity at concentration of 2.0 mg ml–1. Concentrations of 1.0 mg ml–1, as well as lower concentrations showed only minor effects. Another compound, methyl trans-cinnamate, showed 100% activity at concentrations of 0.0625-2.0 mg ml–1. With ethyl trans-cinnamate, 100% mortality was observed at concentrations of 0.25-2.0 mg ml–1. The essential oils and their components described herein merit further study as potential nematicides against the pine wood nematode.

Bacterial Volatiles

Bacterial volatiles represent an important source for new natural nematicidal compounds that may be developed as novel nematicidal agents to control plant-parasitic nematodes. In this study, two marine bacteria,Pseudoalteromonas marinastrain H-42 andVibrio atlanticusstrain S-16, were isolated from seawater and the bay scallop (Argopecten irradians), respectively, collected from the subtidal beds at Qingdao, China.In vitrobioassays indicated that culture supernatants of the two bacteria displayed strong nematicidal activities with corrected mortalities of more than 93% after 24 h exposure against the pine wood nematode (PWN),Bursaphelenchus xylophilus. Maximal nematicidal activity was exhibited by culture supernatants of the two marine bacteria incubated at 15-20°C for 3 days in Zobell 2216E medium prepared with 100% seawater and initial pH 6.0-7.0, inoculating 19-h-old cultures. Through analysis using solid-phase microextraction-gas chromatography/mass spectrometry, the volatiles produced by the two bacteria were shown to contain mainly dimethyl disulphide, benzaldehyde, dimethyl trisulphide,tert-butylamine, acetone and dimethylamine, N-(diisopropylphosphino)methyl-. Results from nematicidal assay using pure commercial compounds instead of the candidate volatiles demonstrated that the four volatile compounds, dimethyl trisulphide (LC90 = 0.060 mmol l−1), benzaldehyde (LC90 = 0.309 mmol l−1), dimethyl disulphide (LC90 = 0.162 mmol l−1) andtert-butylamine (LC90 = 0.366 mmol l−1), showed strong nematicidal activities against PWN. This is the first report on the nematicidal activity of volatile organic compounds (VOC) from marine microorganisms. This study indicates that the nematicidal VOC produced by marine bacteria are potential substitutes for current chemical control options of pine wilt disease caused by PWN which greatly threatens global forest resources.

Medicinal Plant Extracts

Abstract Extracts from 40 medicinal plant species in 27 families were tested for their nematicidal activity against the pine wood nematode, Bursaphelenchus xylophilus, in 96-well plate bioassays. Responses varied with plant material and concentration. Extracts of Acorus gramineus (Araceae), Asiasarum sieboldi (Aristolochiaceae), Illicium verum (Illicaiceae) and Kaempferia galanga (Zingiberaceae) showed nematicidal activity against male, female and juvenile nematodes of B. xylophilus at 2000 μg ml−1. Among test plant species, Kaempferia galanga showed the most potent nematicidal activity. As K. galanga was the most nematicidally active of the 40 species, the extracts were chromatographically fractionated and two cinnamates, ethyl trans-cinnamate and ethyl p-methoxycinnamate, were discovered to be responsible for much of the activity. The nematicidal activity of ethyl trans-cinnamate and ethyl p-methoxycinnamate was 100% at 60 μg ml−1.
