The use of insect sex pheromones is an alternative technology for pest control in agriculture and forestry, which, contrast to insecticides, does not have adverse effects on human health or environment efficient also against insecticide-resistant populations. Due the high cost chemically synthesized pheromones, mating disruption applications are currently primarily targeting higher value crops, such as fruits. Here we demonstrate a biotechnological method production (Z)-hexadec-11-en-1-ol...
Three active components were identified by bioassay-guided fractionation of bitter orange ( Citrus aurantium L.) fruit peel petroleum ether extract. Silica gel the extract yielded a fraction that inflicted up to 96% mortality adults olive fly Bactrocera oleae (Gmelin) three days post-treatment. Subsequent HPLC purification resulted in isolation components, eluted fractions F 222, 224, and 226, induced adult mortality. Considering data obtained from UV, FTIR, MS, (1)H NMR spectra, they as...
Abstract Citrus aurantium (L.) peel extracts in petroleum ether were evaluated for toxicity against olive fruit fly, Bactrocera oleae (Gmelin) and medfly, Ceratitis capitata (Wiedemann) adults. flies more susceptible to the extract than C. contact residual bioassays. Fumigation bioassay had no effect. Both sexes of B. equally both types However, males conspecific females. LD 50 values (concentration causing 50% mortality) after 96 h females 44.8 40.1 μ g/insect through topical application....
Abstract The leopard moth, Zeuzera pyrina (L.) (Lepidoptera: Cossidae), is a xylophagous species that has become serious pest in the olive (Olea spp.) orchards Egypt. Both chemical and biological control have scored poorly against this additional methods are needed. A simple, but efficient UV-light-pheromone sticky trap (“Hegazi model”) was devised for moth mass trapping. Activity of efficiency pheromone-baited, light, pheromone light traps were evaluated. combination sex optimally...
The leopard moth, Zeuzera pyrina (L.) (Lepidoptera: Cossidae), is a damaging pest for many fruit trees (e.g., apple [Malus spp.], pear [Pyrus spp.] peach [Prunus and olive [Olea]). Recently, it caused serious yield losses in newly established orchards Egypt, including the death of young trees. Chemical biological control have shown limited efficiency against this pest. Field tests were conducted 2005 2006 to evaluate mating disruption (MD) on heavily infested, densely planted plots (336 per...
Abstract The leopard moth Zeuzera pyrina L. ( ZP ) is an invasive pest from Europe of increasing significance in North Africa, particular for olive cultivation. We followed the temporal dynamics by combined light/pheromone trapping over a 10‐year period (2002–2011) 240‐ha farm Northern Egypt. had annual cycle with one or two peak flights, late April until October. Time series analysis showed 2‐year trap catch. This likely related to ‘on/off’ bearing pattern olive, where years high and low...
Solvent extracts of differing polarity from Citrus aurantium (L.) (Rutaceae) fruit, leaves, and shoots were evaluated for biological activity against adults the olive fruit fly, Bactrocera oleae (Gmelin) (Diptera: Tephritidae). Using a petri dish residual exposure bioassay, we found that petroleum ether extract alone showed insecticidal flies. The three tissues (flavedo [peel], albedo, flesh) indicated bioactivity was limited to flavedo, this significantly higher than whole extract. most...
Xenobiotic metabolising N-acetyltransferases (NATs) perform biotransformation of drugs and carcinogens. Human NAT1 is associated with endogenous metabolic pathways cells a candidate drug target for cancer. NAT2 well-characterised polymorphic xenobiotic enzyme, modulating susceptibility to drug-induced toxicity. NATs are difficult express high purification yields, complicating large-scale production high-throughput screens or use in sophisticated enzymology assays crystallography. We...
Abstract The European corn borer (ECB) Ostrinia nubilalis is a widespread pest of cereals, particularly maize. Mating disruption with the sex pheromone potentially attractive method for managing this pest; however, chemical synthesis pheromones requires expensive starting materials and catalysts generates hazardous waste. goal study was to develop biotechnological production ECB pheromone. Our approach engineer oleaginous yeast Yarrowia lipolytica produce ( Z )‐11‐tetradecenol 11‐14:OH),...
Cultivation management is essential to balance fundamental parameters for medicinal and aromatic plants (MAPs) such as biomass the production of high-quality oils extracts, with remarkable properties [...]
Intensive crop production and irrational use of fertilizers agrochemicals have questionable effects on the quality products sustainable water for agricultural purposes. Organic cultivation and/or deficit irrigation are, among others, well appreciated practices a system. In present study, spearmint plants (Mentha spicata L.) were grown in different schemes (conventional versus organic cultivation, full irrigation), plant physiological biochemical attributes examined two harvesting periods....
