Antifeedant activity of essential oil Lantana camara L. against Spodoptera litura Fabr. (Lepidoptera: Noctuidae) and Plutella xylostella Curtis (Lepidoptera: Plutellidae)

Abstract Essential oils are well known to act as biopesticides. This research evaluated the acute toxicity and synergistic effect of essential oil compounds in combination with cypermethrin against Spodoptera litura Fabricius (Lepidoptera: Noctuidae). The effects of distillation extracts of essential oils from Alpinia galanga Zingiberaceae (Zingiberales) rhizomes and Ocimum basilicum Lamiaceae (Lamiales) leaves; one of their primary essential oil compounds 1,8-cineole; and linalool were studied on second-instar S. litura by topical application under laboratory conditions. The results showed that A. galanga had the highest control efficiency, whereas1,8-cineole provided a moderate efficacy. The mixtures of linalool, 1,8-cineole, O. basilicum, or A. galanga with cypermethrin were synergistic on mortality. Activity measurements of the main detoxification enzymes show that linalool and 1,8-cineole inhibit the activity of cytochromes P450 and carboxylesterases, which could explain their synergistic effect. Based on our results, the use of these mixtures represents an ideal eco-friendly approach, helping to manage cypermethrin resistance of S. litura.

Larvicidal Activities

The current study was carried out to evaluate antifeedant and insecticidal activities of three essential oils from leaves of Hyptis suaveolens, Chromolaena odorata and Lantana camara against fourth instar larvae of Spodoptera litura under the laboratory conditions. Results indicated that the essential oil from leaves of Hyptis suaveolens had a strong antifeedant impact on the larvae with antifeedant index (AI) of 75.4, 88.5 and 92.9 when leaf disks of Ipomoea batatas were treated with the essential oil at concentration of 1.5, 2.0 and 2.5 %, respectively. Also dose dependent mortalities were observed in the larvae topical treated with the essential oil at different concentrations. At the treated concentration of 0.4 mg per each larva, 68.3 % of the larvae were killed after 24 hours, and 25.0 % were died at the pupal stage after 30 days of observation. At the concentration of 1.2 mg/larva, 93.3 % of the larvae were killed after 24 hours, and no emergence of adults was recorded after 30 days of observation. Larvicidal activity of the H. suaveolens essential oil (with the lethal doses LD50=0.16 and LD95=1.52 mg/larva) was stronger than those of the C. odorata and L. camara essential oils (with LD50=0.57–0.63 and LD95=4.64–4.97 mg/larva) after 24 hour of treatment. GC–MS analysis indicates that the major volatile components of the essential oil from leaves of H. suaveolens are composed of b-caryophyllene (30.0 %), eucalyptol (12.0 %), copaene (5.9 %), and a-bergamotene (5.7 %). This essential oil needs to be further investigated and used as a bio-insecticide for control of S. litura.

Plutella xylostella cause considerable harm to the production of broccoli, Chinese cabbage, cabbage and cauliflower. The control of P. xylostella is mainly performed using commercial insecticides, which have even led to the emergence of resistant populations. Two easily available natural products found in different plants essential oil, thymol and eugenol, stand up as possible novel agents to control this pest. In this work a series of alkylated and acylated derivatives of eugenol and thymol were synthesized and screened for antifeedant, larvicidal and ovicidal activities against P. xylostella. The results of biological activities assays suggest that the novel 1,1’-[1,8-octanediylbis(oxy)]-bis(4-allyl-2-methoxy-benzene) (5) was the most toxic in the larvicidal test. Compounds 1-butoxy-2-isopropyl-5-methyl-benzene (8) and hexanedioic acid 1,6-bis(2-isopropyl-5-methyl-phenyl)-ester (10) were the most toxic in the ovicidal assay. The compound 8 presented the most antifeedant activity. Most of the compounds obtained were more active than commercially available insecticidal deltamethrin and azadirachtin.

Penelitian ini dilaksanakan di desa Balung Lor, kecamatan Balung, kabupaten Jember, selama tiga bulan dimulai September sampai dengan Nopember 2013, bertujuan untuk mengetahui pengaruh teknik budidaya kubis terhadap diversitas arthropoda dan intensitas serangan P. xylostella L. Indeks keanekaragaman arthropoda dianalisis menggunakan indeks keanekaragaman Shanon-Wiener (H'), indeks domonansi Simpson (D) dan indeks kemerataan jenis (E). Untuk membedakan intensitas serangan P. xylostella L. menggunakan uji T pada taraf 5%. Kesimpulan penelitian ini sebagai berikut: diversitas arthropoda pada agroekosistem kubis yang dibudidayakan secara organik maupun konvensional menunjukkan jumlah kelas, ordo, famili dan spesies yang sama yaitu dua kelas, tujuh ordo, empat belas famili dan enam belas spesies. Status dalam jaring makanan meliputi hama terdiri atas sembilan spesies yaitu Oxya chinensis (Orthoptera: Acrididae), P. xylostella L. (Lepidoptera: Plutellidae), Agrotis ipsilon Hufnage (Lepidoptera: Noctuidae), Crocidolomia pavonana Zell. (Lepidoptera: Pyralidae), Myzus persicae Sulz. (Homoptera: Aphididae), Spodoptera litura F.( Lepidoptera: Noctuidae), Chrysodeixis chalcites Esp. (Lepidoptera: Noctuidae), Gryllus assimilis (Orthoptera: Gryllidae) dan Phyllotretta cruciferae (Coleoptera: Chrysomilidae). Lima spesies predator meliputi: Leptogaster sp (Diptera: Asilidae), Oxyopes javanus (Araneae: Oxyopidae), Lycosa sp. (Araneae: Lycosidae), Mantis religeosa (Araneae: Mantidae) dan Solenopsis geminata F. (Hymenoptera: Formicidae), satu parasitoid Diadegma semiclausum Hellen. (Hymenoptera: Ichneumonidae) dan satu detrivora Musca domestica (Diptera: Muscidae). Jumlah individu hama, predator, parasitoid maupun detrivora pada agroekosistem kubis yang dibudidayakan secara organik menunjukkan lebih besar dibanding konvensional. Indeks diversitas arthropoda pada teknik budidaya organik lebih tinggi dibanding konvensional. Intensitas serangan P. xylostella F. pada teknik budidaya organik dibanding konvensional menunjukkan berbeda tidak nyata.
