The aim of this research was to evaluate insecticidal activities of the essential oil of Rhynchanthus beesianus rhizomes against adults of Liposcelis entomophila and Tribolium castaneum . Gas chromatography-mass spectrometry analyses revealed the presence of 44 compounds with β -eudesmol (19.1%), elemol (8.1%), α -terpineol (8.0%), methyl eugenol (6.5%), and caryophyllene (4.8%) being the major constituents. Bioactivity-directed chromatographic separation of the oil led to the isolation of four constituents, elemol, β -eudesmol, methyl eugenol, and α -terpineol. The essential oil exhibited fumigant toxicity against the adults of L. entomophila and T. castaneum with LC 50 values of 0.57 and 4.96 mg/L air while the two isolates, methyl eugenol and α -terpineol possessed fumigant toxicity against the booklice (LC 50 = 0.15 and 0.48 mg/L air, respectively) and the beetles (LC 50 = 1.81 and 4.96 mg/L air, respectively). The oil also possessed contact toxicity against the booklice and the beetles with LD 50 values of 121.56 μg/cm 2 and 54.93 μg/adult, respectively, while the two isolates β -eudesmol and elemol showed contact toxicity against L. entomophila (LD 50 = 99.21 and 35.19 μg/cm 2 , respectively) and T. castaneum (LD 50 = 35.26 and 8.89 μg/adult, respectively). The results indicate that the oil of R. beesianus rhizomes and its isolates have potential as a source for natural insecticides.

Water-distilled essential oil from the dried bulbs of Allium chinense (Liliaceae) was analyzed by gas chromatography–mass spectrometry (GC–MS). Eighteen compounds, accounting for 98.4% of the total oil, were identified and the main components of the essential oil of A. chinense were methyl allyl trisulfide (30.7%), dimethyl trisulfide (24.1%), methyl propyl disulfide (12.8%) and dimethyl disulfide (9.6%) followed by methyl allyl disulfide (3.4%) and methyl propyl trisulfide (3.6%). The essential oil exhibited contact toxicity against the booklice ( Liposcelis bostrychophila ) with an LC 50 value of 441.8 μg/cm 2 while the two major constituents, dimethyl trisulfide and methyl propyl disulfide had LC 50 values of 153.0 μg/cm 2 and 738.0 μg/cm 2 against the booklice, respectively. The essential oil of A. chinense possessed strong fumigant toxicity against the booklice with an LC 50 value of 186.5 μg/l while methyl allyl trisulfide (LC 50 = 90.4 μg/l) and dimethyl trisulfide (LC 50 = 114.2 μg/l) exhibited stronger fumigant toxicity than methyl propyl disulfide (LC 50 = 243.4 μg/l) and dimethyl disulfide (LC 50 = 340.8 μg/l) against the booklice. The results indicated that the essential oil and its major constituents have potential for development into natural insecticides or fumigants for control of insects in stored grains.

The essential oil ofStachys riederivar.japonica(Family: Lamiaceae) was extracted by hydrodistillation and determined by GC and GC-MS. A total of 40 components were identified, representing 96.01% of the total oil composition. The major compounds in the essential oil were acetanisole (15.43%), anisole (9.43%), 1,8-cineole (8.07%), geraniol (7.89%), eugenol (4.54%), caryophyllene oxide (4.47%), caryophyllene (4.21%) and linalool (4.07%). Five active constituents (acetanisole, anisole, 1,8-cineole, eugenol and geraniol) were identified by bioactivity-directed fractionation. The essential oil possessed fumigant toxicity against maize weevils (Sitophilus zeamais) and booklice (Liposcelis bostrychophila), with LC50values of 15.0 mg/L and 0.7 mg/L, respectively. Eugenol and anisole exhibited stronger fumigant toxicity than the oil against booklice. 1,8-Cineole showed stronger toxicity, and anisole as well as eugenol exhibited the same level of fumigant toxicity as the essential oil against maize weevils. The essential oil also exhibited contact toxicity againstS. zeamaisadults andL. bostrychophila, with LC50values of 21.8 µg/adult and 287.0 µg/cm2, respectively. The results indicated that the essential oil ofS. riederivar.japonicaand its isolates show potential as fumigants, and for their contact toxicity against grain storage insects.Keywords:Stachys riederivar.japonica;Sitophilus zeamais;Liposcelis bostrychophila;fumigant;contact toxicity;essential oil

A total of 32 components of the essential oil ofA. calamusrhizomes was identified and the principal compounds in the essential oil were determined to be α-asarone (50.09%), (E)-methylisoeugenol (14.01%), and methyleugenol (8.59%), followed by β-asarone (3.51%), α-cedrene (3.09%) and camphor (2.42%). Based on bioactivity-guided fractionation, the three active constituents were isolated from the essential oil and identified as methyleugenol, (E)-methylisoeugenol and α-asarone. The essential oil exhibited contact toxicity againstL. bostrychophilawith an LD50value of 100.21 µg/cm2while three constituent compounds, α-asarone, methyleugenol, and (E)-methylisoeugenol had LD50values of 125.73 µg/cm2, 103.22 µg/cm2and 55.32 µg/cm2, respectively. Methyleugenol and (E)-methylisoeugenol possessed fumigant toxicity againstL. bostrychophilaadults with LC50values of 92.21 μg/L air and 143.43 μg/L air, respectively, while the crude essential oil showed an LC50value of 392.13 μg/L air. The results indicate that the essential oil ofA. calamusrhizomes and its constituent compounds have potential for development into natural fumigants/insecticides for control of the booklice.Keywords:Acorus calamus;Liposcelis bostrychophila;fumigant;contact toxicity;essential oil composition

The aim of this research was to determine chemical composition and repellent and insecticidal activities of the essential oil of Kaempferia galanga L. rhizomes against the booklouse, Liposcelis bostrychophila Badonnel, and to isolate insecticidal or repellent constituents from the oil. The essential oil was obtained by hydrodistillation and analyzed by gas chromatography–mass spectrometry. Twenty-eight components of the oil were identified. The major compounds in the oil were ethyl-ρ-methoxycinnamate (38.6%), ethyl cinnamate (23.2%), 1,8-cineole (11.5%), trans-cinnamaldehyde (5.3%), and borneol (5.2%). Based on bioactivity-guided fractionation, four active constituents were isolated from the oil and identified as 1,8-cineole, ethyl cinnamate, ethyl ρ-methoxycinnamate, and trans-cinnamaldehyde. The essential oil exhibited contact toxicity against the booklouse with an LC50 value of 68.6 μg/cm2. Ethyl cinnamate (LC50 = 21.4 μg/cm2) exhibited stronger contact toxicity than ethyl ρ-methoxycinnamate and trans-cinnamaldehyde (LC50 = 44.6 and 43.4 μg/cm2, respectively) while 1,8-cineole showed weak acute toxicity. The essential oil also possessed fumigant toxicity against the booklouse with a LC50 value of 1.5 mg/liter air. 1,8-Cineole and trans-cinnamaldehyde (LC50 = 1.1 and 1.3 mg/liter, respectively) possessed stronger fumigant toxicity against the booklouse than ethyl cinnamate and ethyl ρ-methoxycinnamate (LC50 = 10.2 and 10.2 mg/liter air, respectively). trans-Cinnamaldehyde was strongly repellent to booklice, whereas ethyl cinnamate and ethyl ρ-methoxycinnamate were weakly repellent and 1,8-cineole did not repel booklice. The results indicate that the essential oil and its constituent compounds have potential for development into natural insecticides or fumigants and repellents for control of insects in stored grains.

Water-distilled essential oil from T. quadrifarium aerial parts was analyzed by gas chromatography-mass spectrometry (GC-MS). Fourty-seven components comprising 97.2 % of the total oil were identified and the main components of the essential oil were germacrene D (8.8 %), linalool (8.2 %), camphene (7.8 %), β-caryophyllene (7.3 %), β-cadinene (6.8 %), 1,8-cineole (6.5 %), 4-terpineol (5.8 %), and α-terpineol (5.1 %). The essential oil of T. quadrifarium possessed contact toxicity against L. bostrychophila with a LC50 value of 95.1 μg/cm2. The oil also showed fumigant toxicity against L. bostrychophila with a LC50 value of 222.0 μg/l. These findings suggested that the essential oil of T. quadrifarium aerial parts has potential to be developed as new natural insecticides for the control of grain storage insects.
