2. Valorization of Hesperidin from Citrus Residues: Evaluation of Microwave-Assisted Synthesis of Hesperidin-Mg Complex and Their Insecticidal Activity
The aim of the current study was the valorization of hesperidin, the dominant flavonoid in citrus processing waste, by microwave-assisted synthesis of hesperidin-Mg complex, improving its antioxidant activity and insecticidal potential. Here we show, for the first time, that microwave-assisted synthesis of [Mg(hesp)2(phen)]OAc (1) (hesp: hesperidin, phen: ph

4. Silverleaf whitefly-resistant common beans: an investigation of antibiosis and/or antixenosis
ABSTRACT The silverleaf whitefly Bemisia tabaci biotype B is one of the most important sucking pests of common bean, which causes severe damages and requires frequently synthetic insecticides spraying to protect crop productivity. The use of common bean cultivars resistant to whitefly attack is an important strategy within an integrated pest management (IPM)

5. SELECTIVITY OF INSECTICIDES TO Encarsia hispida (Hymenoptera: Aphelinidae)
RESUMO O uso de inseticidas não seletivos na produção agrícola pode reduzir ou eliminar agentes biológicos que regulam os insetos indesejáveis para o homem no processo produtivo. Neste estudo, o efeito da toxicidade de produtos sintéticos foi avaliado para o parasitoide Encarsia hispida tendo como hospedeiro a mosca-branca, Bemisia tabaci biótipo B,

6. Etiology, occurrence and epidemiology of a begomovirus disease in passionflower in the southwest of Bahia
ABSTRACT: Severe mosaic symptoms, accompanied by yellow spots, abnormally small leaves, fruit malformation and cracking, reduced plant growth, and high levels of whitefly (Bemisia tabaci MEAM1) infestation were observed in passionflower (Passiflora edulis) orchards in southwestern Bahia, Brazil. The aim of this work was to identify the species of begomovirus

7. Common bean resistance expression to whitefly in winter and rainy seasons in Brazil
ABSTRACT: Whitefly Bemisia tabaci (Gennadius) biotype B is the major pest of common bean (Phaseolus vulgaris L.) in Brazil and other countries. Host plant resistance is one of the cornerstones of Integrated Pest Management (IPM), and assessment of cultivars for insect resistance is fundamental to provide farmers options for pest control. This study evaluated

8. OTIMIZAÇÃO DA EXTRAÇÃO SÓLIDO-LÍQUIDO COM PARTIÇÃO EM BAIXA TEMPERATURA PARA DETERMINAÇÃO DE CARBOFURANO EM Cucurbita pepo L (“ABOBRINHA”) POR CROMATOGRAFIA LÍQUIDA DE ALTA EFICIÊNCIA
According to results of the Program of Analysis of Pesticide Residues in Foods of the National Agency of Sanitary in Brazil (2013 to 2015) the zucchini, Cucurbita pepo L is one of the non-hardy vegetables, that presented higher contamination index by pesticides residues. One of these agrochemicals is carbofuran, which although not authorized for this crop, i

9. Seasonal dynamics and management of whitefly ( Bemesia tabaci Genn.) in tomato ( Solanum esculentum Mill.)
ABSTRACT Studies on seasonal dynamics of white fly (Bemesia tabaci) on tomato (Solanum esculentum var. Pusa Ruby) revealed that it appeared first during the 13th and reached maximum during 21st standard meteorological week. A positive correlation between adult population and abiotic factors viz. temperature (maximum and minimum) and sunshine hours was obser

10. Microbial control of the invasive spiraling whitefly on cassava with entomopathogenic fungi
Abstract The entomopathogenic fungi Beauveria bassiana, Metarhizium anisopliae, Lecanicillium lecanii and Isaria fumosorosea were tested for their efficacy in managing the exotic spiraling whitefly Aleurodicus dispersus (Hemiptera, Aleyrodidae) on cassava (Manihot esculenta) during 2 seasons (2011-2012 and 2012-2013). The fungi I. fumosorosea and L. lecanii

11. Botanical extracts: alternative control for silverleaf whitefly management in tomato Extratos botânicos: controle alternativo para o manejo de mosca-branca em tomateiro
Bemisia tabaci (Hemiptera: Aleyrodidae) biótipo B é uma das mais limitantes pragas do tomateiro no mundo. A produção do tomateiro é altamente dependente de inseticidas, ocasionando problemas ao produtor, consumidor e ambiente. Uma alternativa promissora para redução dos efeitos maléficos ocasionados pelo uso indiscriminado de inseticidas sintéticos

12. High incidence of Tomato chlorosis virus alone and in mixed infection with begomoviruses in two tomato fields in the Federal District and Goiás state, Brazil
Tomato chlorosis virus (ToCV), a species in the Crinivirus genus, was first reported in tomatoes in Brazil (state of São Paulo) in 2008. This was followed by reports in several other Brazilian states. Tomato plants with chlorotic spots and leaf roll symptoms are frequently observed in tomato fields with high whitefly populations in Central Brazil. These pla
