The Neotropical coffee leaf miner, Leucoptera coffeella (Guérin-Mèneville & Perrottet, 1842), is a key pest species of unshaded plantations in America, particularly Brazil, where management involves intensive insecticide use. As consequence, problems resistance to conventional insecticides are frequent, and more recently developed molecules, such as diamide insecticides, at risk becoming ineffective. Thus, survey the chlorantraniliprole was carried out high-yield coffee-producing areas State...

This study evaluated the effects of gaseous pollutants and vegetation on structure fruit-feeding butterfly communities (some subfamilies Nymphalidae) in a Caatinga area Brumado, BA, between 2016 2018. Two transects were established: Transect “I” (presence pollutant plumes) “II” (absence), encompassing forest fragment pasture. Bait traps installed each transect, analyzed using faunistic indices, including species richness, Shannon diversity index, abundance, dominance. The canopy opening was...

The Neotropical coffee leaf miner is a key pest and in the state of Bahia, one major coffee-producing states country. insect finds favorable conditions for its development, causing production losses intensive use insecticides. Thus, objective study was to analyze aspects profile crops management miner, including insecticide western highland regions Bahia. Data were obtained through questionnaires applied growers and/or technicians included information on total area, area with coffee, native...

Leucoptera coffeella is one of the main coffee pests in Neotropical region and particularly important crops cultivated under full sun, as Brazil. The intensive use insecticides last two decades, including molecules recent such chlorantranilprole, has not been successful suppressing this pest species. Thus, study aimed to detect insecticide resistance determine levels commercial formulations chlorantraniliprole, chlorpyrifos thiamethoxam populations L. from Arabica fields western highlands...

Abstract Climate factors, pesticides, and landscape in coffee agroecosystems directly affect the populations of leaf miner its parasitoids. This study aimed to investigate effects climate insecticide use, on natural parasitism, parasitoid diversity, infestation L . coffeella plantations Planalto region, Bahia, Brazil. Mined leaves were collected monthly six with varying edge density, vegetation cover, diversity scales 500 3000 m radius, factors. Closterocerus coffeellae , Proacrias coffeae...

Coffee (Coffea arabica L.) is one of the main commodities produced in Brazil. Insecticides like (systemic) neonicotinoid thiamethoxam are widely used to suppress pest populations during coffee production, particular Neotropical leaf miner (Leucoptera coffeella Guérin-Mèneville & Perrottet, 1842) (Lepidoptera: Lyonetiidae). In addition its efficacy against this species, also thought be a bioactivator plant metabolism, but has not yet been tested for such activity. Thus, objectives present...

Anastrepha obliqua (Macquart, 1835) is an important pest of tropical fruits, especially Anacardiaceae and Myrtaceae, in the Americas. The objective this study was to evaluate influence mineral films biomaterials on coloring guava fruits (Psidium guajava L.) implications for oviposition A. obliqua. Before bioassays, color, firmness characteristics, total soluble solids, pH, titratable acidity were determined characterize maturation stage fruits. Pieces fruit covered aluminum foil immersed...

Abstract The Mediterranean fruit fly, Ceratitis capitata (Wiedemann), is one of the main pests fruit, worldwide, and use population suppression method with low environmental impact an increasingly strong requirement consumer market. aim this study was to evaluate effect mineral natural films on physical–chemical properties grapes ( Vitis vinifera L.), cultivar Itália, oviposition behaviour C. . Fruits were immersed in suspensions (100 200 g L −1 ) (kaolin Surround ® WP, kaolin 607, 608, 611...

TANNINS AND FLAVONOIDS FROM THE FLOWERS OF EUGENIA UNIFLORA (MYRTACEAE). Eugenia uniflora, popularly known as pitanga, is a native species of the Brazilian flora, widely used in folk medicine for treatment various diseases and which has several bioactive chemical constituents. The aim this work was to analyze composition flowers visited by bees from uniflora Ultra-Performance Liquid Chromatography coupled with Diode Array Detector quadrupole Time Flight Mass Spectrometry...

The coffee leaf miner (Leucoptera coffeella) is one of the major pests crops in neotropical regions, and causes economic losses. Few molecular data are available to identify this pest advances knowledge genome L. coffeella will contribute improving identification also clarify taxonomy microlepidoptera. DNA was extracted sequenced using PacBio HiFi technology. Here we report complete circular mitochondrial (16,407 bp) assembled Aladin software. We found a total 37 genes, including 13...

Com o presente trabalho objetivou-se avaliar a germinação de sementes falso pau-brasil submetidas diferentes métodos superação dormência e períodos armazenamento. O delineamento utilizado foi inteiramente casualizado, em esquema fatorial 2 x 4, correspondendo dois armazenamento (3 meses 3 anos armazenamento) 4 (Escarificação mecânica (lixa n° 80); Termoterapia (60 °C por 15 min); Escarificação + termoterapia Ácido sulfúrico testemunha anos), com repetições 50 sementes. Conclui-se que...

Closterocerus coffeellae (Hymenoptera: Eulophidae) is a parasitoid of the coffee leaf miner occurring in farms with high selection pressure caused by pesticides and different landscape patterns on surrounding crops. This work aims to detect morphometric variations levels Fluctuating Asymmetry (FA) wings C. history insecticide use composition Planalto region, Bahia, Brazil. Parasitoids originated from six this region. We prepared microscopy slides right 30 females each population. determined...

Abstract Background Anthonomus grandis is the main cotton pest in Americas, with potential to become a other continents. The insect uses plant’s reproductive organs for feeding, oviposition, and survival strategies off-season, sheltering dry bolls. This study aimed know potential, longevity, morphometric characteristics of boll weevils from bolls, squares, traps. Adults were obtained infested traps installed fields Caatinga area. Thirty weevil pairs maintained laboratory assess feeding...

Objetivo: Analisar as evidências científicas sobre como os profissionais de enfermagem percebem o acesso, fluxo atendimento e vínculo tecnologia leve no Centro Oncológico. Método: Trata-se uma revisão integrativa literatura nas bases dados BDENF, BVS, LILACS SCIELO, por meio dos descritores “Tecnologias leves”, Enfermagem AND Oncologia, idioma português.

A sample of 22 accessions Brassica oleracea were screened for their responses at the seedling stage to twelve isolates fungal pathogen Peronospora parasitica (downy mildew), and 14 nine Albugo candida (white blister). The results suggested that classic gene-for-gene interactions operate in P. pathosystem whereas A. could be explained either by a model or an additive gene model. Interpretation both pathogens was complicated heterogeneous nature host plant differential lines are therefore...

Abstract Background : To control the boll weevil Anthonomus grandis (Coleoptera: Curculionidae), a key pest of cotton in Americas, insecticides have been intensively used to manage their populations, increasing selection pressure for resistant populations. Thus, this study aimed detect insecticide resistance and assess failure likelihhod populations exposed malathion, profenophos+cypermethrin, fipronil insecticides. Results: Twelve were collected from commercial fileds state Bahia,...
