Abstract Vigna unguiculata , one of the most important legumes, mainly in underdeveloped countries, is susceptible to post-harvest losses storage by Callosobruchus maculatus (Fabricius, 1775) (Coleoptera: Chrysomelidae). The work evaluated toxicity, inhibition oviposition, instantaneous rate population growth (r i ) and development fumigated C. with essential oil Vanillosmopsis arborea its major constituent, α -bisabolol. experimental units consisted 0.8 L flasks treated concentrations...
The essential oil of basil (Ocimum basilicum) has significant biological activity against insect pests and can be extracted through various techniques. This work aimed to optimize validate the extraction process O. basilicum submitted different drying temperatures leaves by combination a Clevenger method ultrasound. under conditions was evaluated for potential control Sitophilus zeamais. optimized according sonication time ultrasound (0, 8, 19, 31 38 min) hydrodistillation (20, 30, 45, 60 70...
In this study, we report the complexities and challenges associated with achieving robust RNA interference (RNAi)-mediated gene knockdown in mosquitoes Aedes aegypti albopictus, a pivotal approach for genetic analysis vector control. Despite RNAi’s potential species-specific targeting, our independent efforts to establish oral delivery of RNAi identifying genes critical mosquito development fitness encountered significant challenges, failing reproduce previously reported potent effects. We...
Abstract. We evaluate regional and interannual variations in tropospheric ozone five chemical reanalyses, consisting of the Copernicus Atmosphere Monitoring Service reanalysis (CAMSRA), second-generation Tropospheric Chemistry Reanalysis (TCR-2), GEOS-Chem reanalysis, Community Multiscale Air Quality (CMAQ) analysis, Chinese air quality (CAQRA). find that there are large differences (about 10–15 nmol mol-1) mean surface between reanalyses. has high relative to ensemble across most...
Abstract Genetic sexing strains (GSS) are important tools for the sterile insect technique (SIT), an environmentally friendly and species‐specific pest control method. GSS feature sex‐specific phenotypes, enabling sex sorting in mass‐rearing facilities male‐only releases, which significantly improve cost‐effectiveness efficiency of SIT programs. In classical GSS, linkage marker gene(s), such as white pupae ( wp ), is achieved through irradiation‐induced translocation between marker‐carrying...
Abstract Given the insecticidal potential of eugenol as a fumigant, this work aimed to determine diffusion coefficient emanating from pure standard solution (99%), well clove essential oil ( Eugenia caryophillata Thunb. (Myrtaceae)) through rice grain; chemically analyse volatile composition commercially available and oil; evaluate mortality Sitophilus zeamais Motschulsky (Coleoptera: curculionidae) after exposure inside test chamber filled with rice. The solid phase microextraction method...
The objective of this work was to evaluate the effectiveness ozone in control fungi and degradation fumonisins maize possible effects on chemical composition product. Two cultivars hybrid (30F53H AS1581 PRO) were used. Initially, saturation process porous medium with studied. incidence Fusarium verticillioides, Penicillium spp. Aspergillus flavus; suitability detoxify grains contaminated by qualitative changes product evaluated. Ozone applied at an inlet concentration 13.5 mg L−1 flow rate...
Double-stranded RNA (dsRNA) can trigger interference (RNAi) and lead to directed silencing of specific genes. This natural defense mechanism RNA-based products have been explored for their potential as a sustainable ecofriendly alternative pest control species agricultural importance disease vectors. Yet, further research, development new possible applications require cost-efficient production dsRNA. In vivo transcription dsRNA in bacterial cells has widely used versatile inducible system...
ABSTRACT The objective of this study was to investigate the influence leaf drying techniques (bench and oven at 35 45 °C) on essential oil (EO) yield Piper aduncum L., anonifolium Kunth, crassinervium Kunth hispidinervum C. DC., analyze chemical profile EOs insecticidal potential these oils against Ascia monuste orseis (Godart), Atta sexdens Zabrotes subfasciatus (Boheman), Cryptolestes ferrugineus (Stephens) Sitophilus zeamais Motschulsky. EO evaluated using four replicates 100g dry leaves....
The salting-out assisted liquid-liquid extraction (SALLE) was developed for the analysis of four pesticides (cypermethrin, chlorpyrifos, deltamethrin, and thiamethoxam) in water samples. For its optimization, a 2³ factorial design used to evaluate simultaneous behavior three factors: sample solvent ratio, saline concentration, stirring mode. A 1.0 mL solution (NaCl) added single-phase mixture separate phases. stirred, allowed stand top organic phase containing interest analyzed by gas...
Bioinsecticides are regarded as important alternatives for controlling agricultural pests. However, few studies have determined the persistence of these compounds in stored grains. This study aimed at optimizing and validating a fast effective method extraction quantification residues safrole (the main component Piper hispidinervum essential oil) cowpea beans. It also sought to assess this substance grains treated by contact fumigation. The proposed used headspace solid-phase microextraction...
The contamination of water bodies by pesticide residues through direct flow, leaching and other methods has motivated the development analytical for determination these compounds in water.A vortex-assisted liquid-liquid microextraction method followed gas chromatography coupled to mass spectrometry anilazine, linuron, prothiofos, tebuconazole samples from culture processing potatoes (Solanum tuberosum L.) was optimized.The complete factorial design central rotational compound combined with...
Callosobruchus maculatus (Fabricius, 1775) (Coleoptera: Chrysomelidae) is the main post-harvest pest of Vigna unguiculata. The objective was to evaluate fumigant activity Ocimum basilicum essential oil and its major components linalool estragole, on C. maculatus, through evaluation toxicity, oviposition inhibition, instantaneous rate population growth (ri) insect development. experimental units were composed 0.8 L flasks treated with concentrations 1.2 3.6 μL L-1 O. oil, linalool, applied...
