... Tetranychus cinnabarinus (Boisduval) is highly polyphagous and is considered one of the most important crop pests, infesting over 100 crop species grown in field and greenhouse crops worldwide. The control of this mite is still based primarily on the use of synthetic chemical pesticides. In this study, 2,4-di-tert-butylphenol (DTBP) and ethyl oleate (EO) were investigated for their acaricidal, rep ...
... To investigate the seed protein and major mineral nutrient (Fe, Zn, P, and N) contents and their accumulation procedure in the seeds of common bean (Phaseolus vulgaris L.), a biennial experiment was conducted under two contrasting moisture regimes (normal irrigation and water deficit). Seed reserves of eight genotypes (WA4502-1, WA4531-17, Akhtar, D81083, AND1007, KS21486, MCD4011, and COS16) were ...

Abstract:
... Common bean breeding programs for white mold (WM) resistance are in their initial stages in Brazil. Sources of partial resistance to WM are available abroad but their performance in Brazil is unknown. In two greenhouse (straw test) and three field experiments conducted in three districts in the state of Minas Gerais, Brazil, we evaluated a total of 23 lines with putative WM resistance with the obj ...
... Generalist arthropod herbivores rapidly adapt to a broad range of host plants. However, the extent of transcriptional reprogramming in the herbivore and its hosts associated with adaptation remains poorly understood. Using the spider mite Tetranychus urticae and tomato as models with available genomic resources, we investigated the reciprocal genomewide transcriptional changes in both spider mite ...
... Agricultural products are highly perishable and drying of the product after harvest has been proved as one of the methods to minimize postharvest losses. Different studies have been conducted to evaluate the performance of a rotary dryer for drying of agricultural products. The advantages and the challenges of rotary dryers in drying of agricultural products are discussed. This study discusses the ...

Abstract:
... Aerodynamic properties of solid materials have long been used to convey and separate seeds and grains during post-harvest operations. The objective of this study was evaluation of the aerodynamic properties of green and red lentil seeds as a function of moisture content from 10 to 25% (w.b.). The results showed that as the moisture content increased from 10 to 25%, the terminal velocity of seeds i ...
... A protocol for genetic transformation of Phaseolus vulgaris L. cv. CIAP7247F via Agrobacterium tumefaciens was established. Primary green nodular calli and proliferative calli were used as target explants. Several factors such as Agrobacterium strain, plasmid, light conditions, bacterial concentration, co-cultivation period and type of callus were studied for optimization of the Agrobacterium-medi ...

Abstract:
... Nitrogen is the major plant nutrient that limits common bean production throughout sub-Saharan Africa. Four experimental trials were conducted at four areas namely Babillae, Fedis, Haramaya, and Hirna experimental sites to determine if various inherent soil fertility status and soil total N might affect the N use efficiency of common bean var. Dursitu. Six levels of N application and two inoculati ...
... A two-season pot experiment was conducted on Phaseolus vulgaris L. plants to evaluate their response to 1.0 mM salicylic acid (SA) in a growing medium contaminated with 0.25 or 0.50 mM Cd2+ ions. Plants were sampled for growth measurements and chemical analyses 45 d after sowing, and to measure the yield of beans at the end of each experiment. Exposing plants to either concentration of Cd2+ ions r ...
... Fusarium head blight, caused by the fungus Fusarium graminearum, has a detrimental effect on both productivity and qualitative properties of wheat. To evaluate its impact on wheat flour, we compared its effect on quality-related parameters between a transgenic bread wheat line expressing a bean polygalacturonase inhibiting protein (PGIP) and its control line. We have compared metabolic proteins, t ...
... , , , Plant feeding can improve development and reproduction of the stink bug Supputius cincticeps (Heteroptera: Pentatomidae), an important biological control agent in South American agro-forestry ecosystems. However, defensive compounds of plants may negatively impact this predator. The development, reproduction and survival of S. cincticeps fed on mealworm, Tenebrio molitor (Coleoptera: Tenebri ...
... Bioactive plants have been studied for their effectiveness in controlling plant diseases, for use in production systems that seek to reduce or eliminate the application of pesticides. This study aimed to evaluate the antifungal activity of plant extracts on common bean soilborne pathogens. We added aqueous extracts from the medicinal plants Baccharis dracunculifolia, Porophyllum ruderale and Schin ...
... AIMS: The main objective of this study was to investigate the effect of various essential oils (EOs) to decrease the activity of cell wall degrading enzymes (CWDEs) produced by fungal phytopathogens, which are associated with disease progress. Also, effect of seed treatment and foliar application of peppermint EO and its main constituent, menthol, on diseases caused by two necrotrophic pathogens o ...
... An actinomycete strain named IA1, which produced an antimicrobial compound, was isolated from a Saharan soil in In Amenas, Algeria. The study of the 16S rDNA sequence of this strain permitted to relate it to Streptomyces mutabilis NBRC 12800ᵀ(99.93% of similarity). Strain IA1 exhibited strong activity against a wide range of plant pathogenic fungi. One bioactive compound produced in large amounts ...
... Legumes and particularly beans are a key food of Mediterranean diet representing an important source of proteins, fiber, some minerals and vitamins and bioactive compounds. We evaluated the antioxidant and anti-mutagenic effects of a new fermented powder of a selected lectin-free and phaseolamin-enriched variety of common bean (Phaseolus vulgaris L.), named Lady Joy. Lady Joy lysate (Lys LJ) was s ...
... Diabrotica speciosa (Germar, 1824) (Coleoptera: Chrysomelidae) is a polyphagous insect pest that attacks several crops of agricultural importance including common beans (Phaseolus vulgaris L.; Fabales: Fabaceae). Diabrotica speciosa larvae feed on the plant root system whereas the adults are leaf defoliators. Diabrotica speciosa control relies mainly on pesticide applications resulting in ecosyste ...

Abstract:
... Maximum likelihood estimation (MLE) is one of the statistical models to estimate parameters or missing values. MLE approach in minimizing first serving order bias (FSOB) was investigated. Two different consumer studies with three wheat breads and nine bean products were performed. To test MLE, consumer ratings of the first product were eliminated from the data, and imputed by MLE. Regression imput ...

Abstract:
... The aim of this work was to develop an aromatic lexicon for evaluating different soymilks with two descriptive methods and an instrumental assistance. A list of 20 terms was generated by eight trained panelists through gas chromatography olfactometry and mass spectrum with free choice profiling for three different soymilk samples. During this phase, panelists randomly used words they were familiar ...
