Provedor de dados: 86
Autores: Oliveira,José Eudes de Morais; Fernandes,Maria Herlândia de Araújo; Gama,Farah de Castro; Botton,Marcos; Carvalho,Andréa Nunes Moreira de.
O objetivo deste trabalho foi avaliar a eficiência da técnica de confusão sexual, com o feromônio sexual sintético composto (Z)-11-hexadecenal (Z11-16: Ald) a 1,8% e (Z)-13-octadecenal (Z13-18: Ald) a 1,8%, no controle da população de traça-dos-cachos, Cryptoblabes gnidiella (Lepidoptera: Pyralidae), em cultivares de videiras (Vitis vinifera) destinadas à produção de vinhos. Os experimentos foram realizados em duas localidades na região do Vale do São Francisco, em áreas comerciais de produção de uva para processamento, com as cultivares Cabernet Sauvignon, Petit Verdot, Tempranillo e Chenin Blanc. Os tratamentos avaliados foram os seguintes: confusão sexual com uso de liberadores Splat ("specialized pheromone and lure application technology"), aplicados...

Abstract: The objective of this work was to evaluate the lethal and sublethal toxicity of hexane and methanolic extracts from the leaves of Annona vepretorum (Annonaceae) on Tetranychus urticae (Acari: Tetranychidae). The methanolic extract toxicity was evaluated by Potter tower application (topical + residual effect) and by immersion of Canavalia ensiformis leaf disks in the extract solution (residual contact effect). The hexane extract toxicity was evaluated exclusively through residual contact effect. Sublethal effects of the methanolic extract were evaluated through LC50 on the females. Mite preference for feeding and oviposition was evaluated by multiple choice tests, between the control and the extract concentrations, using the hexane and methanolic...

Coccidoxenoides perminutus parasitizing Planococcus citri on vine in Brazil
Provedor de dados: 65
Autores: Fernandes,Maria Herlândia de Araújo; Oliveira,José Eudes de Morais; Costa,Valmir Antônio; Menezes,Karen Oliveira de.
ABSTRACT: From those of the mealybug family, the citrus mealybug, Planococcus citriRisso, 1813 (Hemiptera: Pseudococcidae) is frequently held responsible for various diseases occurring in vineyards. This is a first time report in Brazil, on the occurrence of a parasitoid controlling P. citri. In our search for the natural enemies of P. citri, bunches of grapes with the vine were collected every week for one month, in those regions where table grapes were produced, like Petrolina, Pernambuco, Brazil. In these samples, among the natural pest infestations  Coccidoxenoides perminutusGirault, 1915 (Hymenoptera: Encyrtidae) was the only natural enemy species reported. In this research, we attempted to study the potential of parasitism as well as the strategies...
