Effects of Teucrium polium L. (Lamiaceae) essential oil and α-pinene on the detoxifying-and intermediary engaged enzymes of Ephestia kuehniella Zeller, 1879 (Lep.: Pyralidae)Abstract: This study investigated the effect of Teucrium polium L. essential oil (Tp EO) and α-pinene as its major component on the detoxifying-and intermediary-engaged enzymes of Ephestia kuehniella Zeller. Fourth instar larvae were separately fed on the treated artificial diets incorporated with LC 50 concentration of Tp EO (4.91 μl ml −1 ) and α-pinene (10.66 μl ml −1 ). After three time intervals (24, 48, 72 hours), larval hemolymph was extracted to determine enzymatic activities. Activity of esterase, alanine and aspartate aminotransferases, aldolase, lactate dehydrogenase, and alkaline phosphatase were decreased in the treatments compared with the control. No significant differences were observed between some enzymes in the treated larvae highlighting their ineffectively role to detoxify and to metabolize Tp EO and α-pinene in the hemolyph of E. kuehniella larvae. Učinki eteričnih olj in α-pinena iz istrskega vrednika (Teucrium polium L.) na razstrupljevanje in aktivnosti pri tem sodelujočih encimov močne vešče (Ephestia kuehniella Zeller, 1879, Lepidoptera: Pyralidae)Izvleček: V raziskavi so bili preučevani učinki eteričnih olj in α-pinena kot njihove glavne sestavine iz istrskega vrednika (Teucrium polium L., Tp EO) na njihovo razstrupljanje in aktivnosti pri tem udeleženih encimv močne vešče (Ephestia kuehniella Zeller, 1879). Ličinke četrtega štadija so bile hranjene z umetnimi pripravki, ki so vsebovali LC 50 koncentracijo Tp EO (4,91 μl ml −1 ) in α-pinena (10,66 μl ml −1 ). Po treh časovnih presledkih (24, 48, 72 ur) je bila za določanje encimske aktivnosti ekstrahirana hemolimfa ličink. Aktivnosti esteraze, alanin in aspartat aminotransferaz, aldolaze, laktat dehidrogenaze in alkalne fofataze so se zmanjšale po obravnavanjih v primerjavi s kontrolo. Pri tretiranih larvah ni bilo značilnih razlik med posameznimi encimi, kar kaže na neučinkovitost fiziologije močne vešče pri tretiranju s Tp EO ali z α-pinenom.Ključne besede: Teucrium polium L.; močna vešča; eterična olja; detoksifikacijski encimi; fenoloksidaza; toksičnost; fiziološki odziv Acta agriculturae Slovenica, 113/2 -2019 252 M.

Essential oils (EOs) have been recognized as an important source of biopesticides. This work investigated the chemical constituents and bioactivity of six essential oils namely lavender (Lavandula angustifolia Mill.), peppermint (Mentha piperita L.), geranium (Geranium maculatum L.), palmarosa (Cymbopogon martinii (Roxb.) Wats), eucalyptus (Eucalyptus globulus Labill.) and bergamot (Citrus bergamia Risso) against adults of the Indian meal moth, Plodia interpunctella, a cosmopolitan pest that infests a wide range of stored products. Analysis by gas chromatography coupled to mass spectrometry (GC-MS) revealed the presence of several compounds, mainly mono-and sesquiterpenes. The contact toxicity assay showed that the EO from palmarosa was the most toxic with a LD50 value of 22.8 µg cm-2. The toxicity order was palmarosa > geranium > peppermint > lavender > bergamot >eucalyptus. In fumigant toxicity assay, the greatest effect was found with the EO from eucalyptus with a KT50 value of 8.34 min. The toxicity order was eucalyptus > peppermint >geranium = lavender > bergamot > palmarosa. The EO from palmarosa showed the highest residual activity when the insects were exposure to its volatiles constituents. Finally, all EOs produce sublethal activity promoting effects in the fecundity. In conclusion, the EOs could be used as potential biopesticides for P. interpunctella control.

“…Currently, using conventional insecticides is the principal means to control G. pyloalis populations. However, the heavy use of insecticides in mulberry growing regions has caused silkworm poisoning and environmental pollution, as well as increased G. pyloalis resistance to a variety of chemical insecticides including organophosphates, pyrethroids, and carbamates [ 2 ]. Therefore, there is an urgent need for environmentally-friendly methods to control G. pyloalis .…”

Glyphodes pyloalis Walker (G. pyloalis) causes significant damage to mulberry every year, and we currently lack effective and environmentally friendly ways to control the pest. Chitin synthase (CHS) is a critical regulatory enzyme related to chitin biosynthesis, which plays a vital role in the growth and development of insects. The function of CHS in G. pyloalis, however, has not been studied. In this study, two chitin synthase genes (GpCHSA and GpCHSB) were screened from our previously created transcriptome database. The complete coding sequences of the two genes are 5,955 bp and 5,896 bp, respectively. Expression of GpCHSA and GpCHSB could be detected throughout all developmental stages. Relatively high expression levels of GpCHSA occurred in the head and integument and GpCHSB was most highly expressed in the midgut. Moreover, silencing of GpCHSA and GpCHSB using dsRNA reduced expression of downstream chitin metabolism pathway genes and resulted in abnormal development and wings stretching, but did not affect normal pupating of larvae. Furthermore, the inhibitor of chitin synthesis diflubenzuron (DFB) was used to further validate the RNAi result. DFB treatment significantly improved expression of GpCHSA, except GpCHSB, and their downstream genes, and also effected G. Pyloali molting at 48 h (62% mortality rate) and 72 h (90% mortality rate), respectively. These results show that GpCHSA and GpCHSB play critical roles in the development and wing stretching in G. pyloalis adults, indicating that the genes are attractive potential pest control targets.
