AbstractSoybean oil (SO) is considered an active ingredient in commercial BiteBlocker™ insect-repellent products. Our objective was to test mechanisms by which SO exhibits repellency, using the yellow fever mosquito, Aedes aegypti (L.) (Diptera: Culicidae), as a representative blood-feeding insect. In dual-port glass-cage olfactometers, human hands treated with SO at various concentrations attracted as many mosquitoes as did untreated hands, indicating that SO has no long-range repellent effect. In contrast, hands treated with N,N-diethyl-3-methylbenzamide (DEET) attracted significantly fewer mosquitoes than did untreated control hands. In cage experiments, treating an area of a human forearm exposed to A. aegypti with SO provided no protection against bites, whereas treating it with DEET did. These results indicate that SO has no short-range or contact repellent properties. Both DEET and the BiteBlocker™ product conferred protection for periods similar to those previously reported. Based on our data, classification of SO as an active mosquito repellent should be reconsidered.

Frequent Use

The mosquito Aedes aegypti is an epidemic vector of several diseases such as dengue fever and yellow fever. Several pesticides are used to control the mosquito population. Because of their frequent use, some mosquitoes have developed resistance. In the present study, we evaluated the synergistic mosquito-repellent activity of essential oils from Pelargonium radula, Syzgium aromaticum and Citrus aurantifolia against Aedes aegypti by using Y-tube olfactometer. The oils was subsequently analyzed by using GC–MS. These results clearly reveal that the essential oil of C. aurantifolia served as the most potent repellent agent against Aedes aegypti . The results indicate that three constituents; limonene (19.58%) followed by β–pinene (17.12%), geraniol (13.23%) which comprise a large proportion of the C. aurantifolia are likely responsible for the observed repellent activity.

ABSTRAK   Tujuan penelitian adalah untuk mengetahui potensi ekstrak buah mangrove Xylocarpus granatum sebagai anti larva nyamuk Aedes aegypti. Uji larva nyamuk dengan memasukkan masing-masing 10 ekor larva nyamuk yang dimasukkan ke dalam 7 botol cup tranparan kecil,  masing– masing untuk 50, 100, 250, 500, 1000 ppm sampel ektrak,  kontrol negative dan  kontrol positive. Hasil penelitian memperlihatkan bahwa pengaruh  tingkat mortalitas larva nyamuk terhadap ekstrak buah mangrove Xylocarpus granatum pada jam 1 memperlihatkan bahwa pada konsentrasi 1000 ppm, persentasi mortalitas nyamuk tertinggi adalah 81,34 %, dan pada konstrasi ekstrak buah mangrove Xylocarpus granatum 100 ppm terendah  mortalitasnya =  68,8%. Perlakuan pada jam 3 memperlihatkan bahwa pada konsentrasi ekstrak buah mangrove 500 ppm tingkat mortalitas larva nyamuk tertinggi (80%).  Pada konsentrasi ekstrasi buah mangrove 250 ppm, mortalitasnya 66,70% dan konsentrasi ekstral buah mangrove pada 100 ppm, mortalitasnya adalah 40%. Hasil peneltian pada jam ke 24 memperlihatkan bahwa pada konsentrasi ekstrak buah mangrove mencapai 1000 pmm, mortalitasnya 100%, pengamatan jam ke 48  mortalitasnya  100%. Sedang pada perlakuan control positif, keluulushidupan larva nyamuk adalah 0% dan pada control negative, kelulushidupan larva nyamuk adalah 100%. Kesimpulan:  bahwa ekstrak buah mangrove Xylocarpus granatum berpotensi sebagai anti larva nyamuk pada konsentrasi 1000 ppm.   ABSTRACT   It was assumed that mangrove fruits has some insecticidal biosubstances. Aim of the research is the potentials of mangrove Xylocarpus granatum fruit extract as the anti mosquito (Aedes aegypti) repellent. Experiment using of 10 mosquito larvae in 7 bottles each filled with 50; 100; 250; 500 and 1000 ppm fruit extract, negative  and positive control.  The experiment reveals that after 1 hour treatment, the 1000 ppm exctract had the hihgest mosquito larvae mortality of 81.34%, while the lowest extract of 100 ppm had 68.8% mortality.  After 3 hours of extract treatment the 500 ppm had the hihgest mortality of 80%, 250 ppm with 66.70% and 100 ppm with 40 % mortality.  Result of experiment after 24 as well as  48 hours treatment the 1000 ppm extract had 100% mortality.  In the positive control had 0% mortality and the negative control had 100% of survival. The summary is that the mangrove Xylocarpus granatum fruit extract had a potential as mosquito repellent at 1000 ppm fruit extract.

Sesquiterpene Hydrocarbons

The essential oil (EO) of Lantana montevidensis (Spreng.) Briq. (L. sellowiana Link & Otto) was investigated for its chemical composition and mosquito repellent activity. The essential oil obtained by hydrodistillation of aerial plant parts was analyzed by GC-FID and GC-MS. The major constituents were β-elemene (22.0%), β-caryophyllene (20.1%), and germacrene D (9.4%). Sesquiterpene hydrocarbons were present in considerable quantities (78.9%) in the L. montevidensis EO, followed by oxygenated sesquiterpenes (8.9%), monoterpene hydrocarbons (7.7%), oxygenated monoterpenes (1.9%), diterpenes (1.2%) and other compounds (0.2%). The oil of L. montevidensis was repellent with a minimum effective dosage (MED) of 0.021 ± 0.013 mg/cm2 as compared with that of the positive control N,N-diethyl-3-methylbenzamide (DEET) with a MED of 0.006 ± 0.001 mg/cm2) against Aedes aegypti L. The major compound β-elemene was tested individually for its repellency and had a MED value of 0.23 ± 0.14 mg/cm2 (DEET was 0.008 ± 0.001 mg/cm2). This is the first report on the repellent activity of L. montevidensis EO and β-elemene using human-based in vivo assays against Ae. aegypti.
