“…Therefore, A. galanga essential oil which has a high percentage of 1,8-cineol can be used to control C. gestroi and C. curvignathus due to its antifeedant action. Similarly, a study conducted by Abeywickrama et al (2006) also confirmed that 1,8-cineol was the major constituent in the essential oil of A. calcarata. 1,8-cineole is known as the marker compound for Alpinia spp.…”

Dual choice bioassays were used to evaluate the antifeedant property of essential oil and methanolic extract of Alpinia galanga (L.) (locally known as lengkuas) against two species of termites, Coptotermes gestroi (Wasmann) and Coptotermes curvignathus (Holmgren) (Isoptera: Rhinotermitidae). A 4-cm-diameter paper disc treated with A. galanga essential oil and another treated with either methanol or hexane as control were placed in a petri dish with 10 termites. Mean consumption of paper discs (miligram) treated with 2,000 ppm of essential oil by C. gestroi was 3.30 ± 0.24 mg and by C. curvignathus was 3.32 ± 0.24 mg. A. galanga essential oil showed significant difference in antifeedant effect, 2,000 ppm of A. galanga essential oil was considered to be the optimum concentration that gave maximum antifeedant effect. The essential oil composition was determined using gas chromatography-mass spectrometry. The major component of the essential oil was 1,8-cineol (61.9%). Antifeedant bioassay using 500 ppm of 1,8-cineol showed significant reduction in paper consumption by both termite species. Thus, the bioactive agent in A. galangal essential oil causing antifeeding activity was identified as 1,8-cineol. Repellent activity shows that 250 ppm of 1,8-cineol caused 50.00 ± 4.47% repellency for C. gestroi, whereas for C. curvignathus 750 ppm of 1,8-cineol was needed to cause similar repellent activity (56.67 ± 3.33%). C. curvignathus is more susceptible compare to C. gestroi in Contact Toxicity study, the lethal dose (LD50) of C. curvignathus was 945 mg/kg, whereas LD50 value for C. gestroi was 1,102 mg/kg. Hence 1,8-cineol may be developed as an alternative control against termite in sustainable agriculture practices.

“…Since the demand for the lemongrass oil is determined by Citral content of the oil, of Cymbopogon citrates, oil with higher Citral is key factor of lemongrass essential oil (Tajidin et al, 2012). Interestingly, Citral has been identifi ed as a compound which is mainly responsible for antimicrobial properties of lemon grass oil (Paranagama et al, 2002;Palhano et al, 2003).…”

Purpose: Lemongrass (Cymbopogan citrates (DC) Stapf. ) is ranked among the top ten oil bearing crops in the world and the essential oils of lemongrass are widely used in pharmaceutical, cosmetics, food and fl avor, agriculture industries and possess an array of medicinal uses. Aromatic grasses respond well to application of manures and fertilizers. However, farmers do not use fertilizer. Therefore, it is very important to fi nd out the possibility to increase oil yield and improve the quality of essential oil by applying inorganic and organic fertilizer. Therefore, a study was conducted to investigate the eff ect of fertilizers on crop growth, bio mass production, oil yield and chemical composition of Lemongrass.Research Method: Three diff erent fertilizer mixtures (F1:compost only, F2: inorganic fertilizer (urea, triple super phosphate and muriate of potash at the rate of 278, 296 and 175kg/ha respectively) and F3: inorganic fertilizer + Compost) were used with (F0) control (without fertilizer). Randomized Complete Block Design (RCBD) was used as the experimental design. Number of leaves, tillers and plant height (cm) were recorded. Oil yield and chemical composition of fi ve months old plants were evaluated. Essential oil was extracted by hydro distillation and chemical composition of essential oil was analyzed by Gas Chromatography and Mass Spectrometry. Highest herbage yield (15.94 t ha-), dry matter yield (4.82 t ha-) and oil yield (fresh wgt. basis) (59.16 kg ha-) were recorded in the treatment of F3 (Compost 106.5g: Urea 2.96g: TSP 3.15g: MOP 1.86g per plant). Citral, β-Citral, Geraniol, α Pinene, cis -Verbenol were major chemical compounds identifi ed in oil. Findings: Research Limitations:The study focused on whether there were benefi ts of using organic and inorganic fertilizers for lemongrass cultivation. However, the research was done only for a limited number of fertilizer mixtures. Further research with diff erent fertilizer mixtures will off er most suitable mixture of fertilizers.Originality/Value: Present study revealed that, application of inorganic fertilizer along with compost result best growth performances and highest oil yield with high quantities of economically important major chemical constituents in lemongrass.

“…Thus, further studies may need to observe possible synergistic or antagonistic effects of the isolates. On the basis of a literature survey, the three constituents, 1,8-cineole, geraniol, and eugenol, have been shown to possess insecticidal and acaricidal activities, as well as repellency against several insects/mites, including maize weevils ( S. zeamais ) and booklice ( L. bostrychophila ) [ 21 , 22 , 23 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 ]. However, this is the first report showing that anisole and acetanisole possess insecticidal activities against the two grain storage insects.…”

The essential oil of Stachys riederi var. 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 LC50 values 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 against S. zeamais adults and L. bostrychophila, with LC50 values of 21.8 µg/adult and 287.0 µg/cm2, respectively. The results indicated that the essential oil of S. riederi var. japonica and its isolates show potential as fumigants, and for their contact toxicity against grain storage insects.
