Allelochemical effects were observed when Tribolium castaneum (Herbst) adults treated with Baccharis salicifolia (Ruiz & Pavon) Pers essential oil. The main biological activities toxicity and repellence. Terpenes present in the oil identified by GC-MS, some authentic samples tested to assess their activity individually. most acutely toxic compounds after 3 days beta-pinene pulegone. Most of monoterpenes elicited symptoms indicative neurotoxicity. repellent compound was alpha-terpineol. Toxic...
Abstract Transgenic maize producing the Cry1Ab toxin of Bacillus thuringiensis (Bt maize) was approved for cultivation in European Union (EU) 1998 to control corn borers Sesamia nonagrioides (Lefèbvre) and Ostrinia nubilalis (Hübner). In EU since then, is only Bt produced by Spain country where has been planted every year. 2021, about 100,000 hectares were cultivated EU, with accounting 96% Portugal 4% this area. both countries, represented less than 25% all a maximum regional adoption 64%...
Bt maize cultivars based on the event MON810 (expressing Cry1Ab) have shown high efficacy for controlling corn borers. However, their efficiency some secondary lepidopteran pests such as Mythimna unipuncta has been questioned, raising concerns about potential outbreaks and its economic consequences. We selected a resistant strain (MR) of M. unipuncta, which is capable completing life cycle displays similar performance when feeding both non-Bt maize. The proteolytic activation protoxin...
Background: Different serotypes of Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis have been shown to induce differential dendritic cell (DC) responses. This study investigates whether cytokine CC‐chemokine receptor (CCR) production by DCs stimulated with different A. or P. is Toll‐like 2 (TLR2) and/or TLR4 dependent. Methods: were obtained from healthy individuals primed at a multiplicity infection (MOI) 10 in the presence absence anti‐TLR2 anti‐TLR4 blocking antibodies....
Growth inhibitory activities and nutritional indices of catalpol (1), 8-O-acetylharpagide (2), harpagide (3) were determinated in larvae adults Tribolium castaneum, respectively. Compound 1 produced a series allelochemical effects probably related with the DNA synthesis. This iridoid possessed highest activity against polymerase. Molecular orbital calculations suggest that π−π charge transfer recognition model could explain action iridioids toward nucleic acid
BACKGROUND The low efficacy of MON810 maize against Mythimna unipuncta represents a scenario non-compliance with the 'high-dose' strategy, raising concerns about potential resistance development and outbreaks this secondary pest. present study offers insight into different components related to in laboratory-selected MON810-resistant (MR) strain M. unipuncta. RESULTS MR is autosomal inherited as partially dominant trait. We have found lack fitness costs for essential life history traits,...
Abstract A laboratory study was carried out to assess the potential prey-mediated effects of Cry3Bb1-expressing Bt maize on fitness and predatory ability Atheta coriaria Kraatz (Coleoptera: Staphylinidae), using Tetranychus urticae Koch (Acari: Tetranychidae) as prey. The concentration Cry3Bb1 toxin through trophic chain significantly decreased from (21.7 μg g −1 FW) mites (5.6 then A. adults (1.4 FW), but not L 1 –L 3 larvae (4.1–4.6 FW). Interestingly, levels detected in represent more...
A tin oxide multisensor with eight sensor elements has been utilized to detect different gases that are emitted from the chemical industry. The sensors have prepared using RF reactive sputtering technique. Some components of this were doped Pt and Cr by sputtering. Each characterized electrical measurements for detection atmospheric pollution (nitrogen dioxide, carbon monoxide, toluene, propanal). detected toxic their extreme concentrations recommended in air oscillate 1 ppm hundreds ppm....
This paper reports the use of an electronic nose for identification spoiled hams during curing process. The sensors involved are tin oxide semiconductor thin films. They were prepared by RF sputtering. Some doped with metal catalysts as Cr and In. A good discrimination two types Iberian (spoiled unspoilt) has been obtained through statistical methods principal component analysis (PCA) probabilistic neural network (PNN).
Abstract The cultivation of Cry1Ab‐expressing genetically modified MON810 (Bt maize) has led to public concern in Europe, regarding its impact on nontarget arthropods (NTAs). We have assessed the potential effects DKC 6451 YG (MON810) maize canopy NTAs a farm‐scale study performed Central Spain during 3 years. focused hemipteran herbivores (leafhoppers and planthoppers) hymenopteran parasitic wasps (mymarids) collected by yellow sticky traps, which accounted for 72% total number insects...
