Exposure to cyantraniliprole causes mortality and disturbs behavioral and respi...
Plata-Rueda, Angelica; Martínez, Luis Carlos; Silva, Brenda Karina R. da; Zanuncio, José C.; Fernandes, Maria Elisa de S.; Guedes, Raul Narciso C.Hypothenemus hampei Ferrari (Coleoptera: Curculionidae) is the main pest of coffee due to the damage caused to coffee berries. Effective management methods and prevention of insecticide resistance are urgently needed against this insect. Bioassays were conducted to assess the effects of the diamide insecticide cyantraniliprole on H. hampei. Cyantraniliprole is the most recent compound registered against this sp...
Injury and spatial distribution of Spodoptera frugiperda (J. E. Smith) (Lepidop...
Fernandes, Flávio L.; Diniz, Juno F. S.; Alves, Flávia M.; Silva, Luiz O. D.Genetically modified plants protect the crop of maize (Zea mays) from fall armyworms (Spodoptera frugiperda) (J. E. Smith), which are responsible for great losses in maize crops. This plague might spread to other areas and feed on alternative hosts. Among these hosts, attack of such caterpillars on commercial crops of onions (Allium cepa) has been noted in Alto do Paranaíba, Minas Gerais, Brazil. This paper rep...
Lethal and sublethal effects of seven insecticides on three beneficial insects ...
Fernandes, Maria E.S.; Alves, Flávia M.; Pereira, Renata C.; Aquino, Leonardo A.; Fernandes, Flávio L.; Zanuncio, José C.Lethal and sublethal effects of insecticides on target and non-target arthropods are a concern of pest management programs. Cycloneda sanguinea, Orius insidiosus and Chauliognathus flavipes are important biological control agents for aphids, whitefly, lepidopterus eggs, thrips and mites. All three test species were subjected to a toxicity study using the insecticides acephate, bifenthrin, chlorantraniliprole, ch...
A sampling plan for Liriomyza huidobrensis (Diptera: Agromyzidae) on a potato (...
Alves, Flávia M.; Silva, Ítalo Willian da; Fernandes, Flávio L.; Fernandes, Flávio L.; Gorri, Jéssica E. R.; Diniz, Juno F. S.No sampling plans specifically developed for mines associated with the pest Liriomyza huidobrensis in potato fields have been published to date. Thus, the objectives of this study were to determine the sampling unit and to establish the number of samples needed for the application of this study’s sampling plan. For this purpose, we evaluated 16 commercial fields of the potato cultivar Agata (24.5 ha). We evalua...
Trichomes and hydrocarbons associated with the tomato plant antixenosis to the ...
Silva, Derly J.H.; Picanço, Marcelo C.; Jhamc, Gulab N.; Carneiro, Pedro C.; Queiroz, Renan B.; Fernandes, Maria Elisa S.; Fernandes, Flávio L.O objetivo desse trabalho foi estudar a densidade de tricomas e os hidrocarbonetos associados à resistência por antixenose de 42 subamostras de tomateiro do Banco de Germoplasma de Hortaliças da Universidade Federal de Viçosa (BGH-UFV) a Liriomyza trifolii. Essas subamostras foram estudadas e a cultivar 'Santa Clara' que foi utilizada como padrão de suscetibilidade a insetos minadores. As características avalia...
