Susceptibility of Alphitobius diaperinus (Panzer) (Coleoptera, Tenebrionidae) to cypermethrin, dichlorvos and triflumuron in southern Brazil. The lesser mealworm, (Panzer), is an important insect pest poultry houses the mealworm collected from eight Paraná state, Brazil, was evaluated for triflumuron. Adult A. were tested bioassays with cypermethrin dichlorvos. Larvae fed rabbit feed wetted a triflumuron-water solution. Concentration-mortality regressions estimated using Probit analysis...

Seed coat characteristics may be related to seed quality and longevity, attracting the interest of breeding programs. This study aimed evaluate relationship between water absorption parameters storage tolerance soybean seeds with contrasting characteristics. For this purpose, five cultivars different colors lignin contents were used. Before storage, content, moisture rate in 11 hydration periods (1, 2, 3, 4, 5, 6, 7, 8, 24, 32, 48 hours), speed index, germination, viability, vigor...

The delineation of management zones is one the ways to enable spatially differentiated plots using precision agriculture tools. Over years, spatial variability data collected from soil and plant sampling started be replaced by proximal orbital sensors. As a result, variety volume have increased considerably, making it necessary use advanced computational tools, such as machine learning, for analysis decision-making support. This paper presents methodology used establish (MZ) in analyzing...

Small heat shock proteins (sHSPs) belong to the class of molecular chaperones that respond biotic and abiotic stresses in plants. A previous study has showed strong induction gene GmHsp22.4 response nematode Meloidogyne javanica a resistant soybean genotype, while repression susceptible one. This aimed investigate functional involvement this small chaperone M. Arabidopsis thaliana. First, it was evaluated activation promoter region after inoculation, occurrence polymorphisms between...

Abstract Background Discovery of microRNAs (miRNAs) relies on predictive models for characteristic features from miRNA precursors (pre-miRNAs). The short length genes and the lack pronounced sequence complicate this task. To accommodate peculiarities plant animal miRNAs systems, tools both systems have evolved differently. However, these are biased towards species which they were primarily developed and, consequently, their performance data sets other same kingdom might be lower. While...

Differences in seed storage tolerance between soybean cultivars have been frequently observed. Thus, identifying compounds found them that may be related to these differences is necessary support the selection of with seeds better potential. Therefore, this study aimed evaluate changes viability and vigor during two environments, relating antioxidant activity, production reactive oxygen species, metabolites phenylpropanoid pathway. The experimental design was completely randomized a 4 × 5...

ABSTRACT: Phytotoxic effects induced in soybean seedlings by exposure to various pesticides can lead shortened and thickened hypocotyls, taproot atrophy, reduced development or absence of secondary roots. This study aimed validate the Vigor-S image analysis system for characterizing phytotoxic on resulting from seed treatment using different products. Soybean seeds cultivar BRS 284 received three treatments: cyproconazole fungicide, which causes hypocotyl shortening; glyphosate herbicide,...
