Laboratory evaluation of acute toxicity of the essential oil of Allium tuberosum leaves and its selected major constituents against Apolygus lucorum (Hemiptera: Miridae)
Journal of Insect Science 15 (117), 1-4
Abstract: The aim of this research was to evaluate acute toxicity of the essential oil of leaves of Chinese chives, Allium tuberosum Rottler ex Spreng (Asparagales: Alliaceae) and its major constituents against Apolygus lucorum Meyer-Dür (Hemiptera: Miridae). The essential oil of A. tuberosum leaves was obtained by hydrodistillation and analyzed by gas chromatography and gas chromatography-mass spectrometry. The major constituents of the oil were sulfur-containing compounds, including allyl methyl trisulfide (36.24%), diallyl disulfide (27.26%), diallyl trisulfide (18.68%), and dimethyl trisulfide (9.23%). The essential oil of A. tuberosum leaves exhibited acute toxicity against Ap. lucorum with an LD₅₀ value of 20.03 µg per adult. Among the main compounds, diallyl trisulfide (LD₅₀ = 10.13 µg per adult) showed stronger acute toxicity than allyl methyl trisulfide (LD₅₀ = 21.10 µg per adult) and dimethyl trisulfide (LD₅₀ = 21.65 µg per adult). The LD₅₀ value of diallyl disulfide against Ap. lucorum was 28.10 µg per adult. The results indicated that the essential oil of A. tuberosum and its major constituents may have a potential to be developed as botanical insecticides against Ap. lucorum.
