The aim of this study was to develop a microemulsion from the essential oil Citrus aurantium var. dulcis (EOCA) as an alternative synthetic pesticides, and evaluate its efficacy against Aleurocanthus woglumi selectivity towards natural enemies Aschersonia aleyrodis Ceraeochrysa cornuta. Chemical composition determined by gas chromatography coupled with mass spectrometry revealed limonene, myrcene, linalool α-pinene major components. prepared using ternary diagram illustrating water, oil,...
A new species of cixiid planthopper (Hemiptera: Fulgoroidea) in the genus Oecleus Stål, sergipensis n. sp., is described from Sergipe State, Brazil. This taxon associated with coconut (Cocos nucifera L.) and date palm (Phoenix L). The was detected Auchenorrhyncha surveys to find potential vectors lethal yellowing type syndrome. first report Sequence data mitochondrial cytochrome c oxidase subunit I (COI) barcoding region obtained accessioned into GenBank.
Entomopathogenic fungi are microbial agents of insect control in nature. They have been used as biologic strategies to manage invasion; however, the challenge is maintain their shelf life and viability when exposed high temperatures, ultraviolet radiation, humidity. Synthesized silver nanoparticles (AgNPs) from fungal extracellular enzymes an alternative using these microorganisms obtain with insecticidal action. The present study evaluates biomass production potential synthesize...
Resumo: O objetivo deste trabalho foi avaliar o desempenho de Trichogramma galloi (Hymenoptera: Trichogrammatidae) sobre ovos Diatraea flavipennella e D. saccharalis (Lepidoptera: Crambidae), assim como as características biológicas do parasitoide em ambos os hospedeiros, elaborar a tabela vida fertilidade. Para isso, foram realizados testes com sem chance escolha bioensaios para hospedeiros. A fertilidade elaborada por meio parasitismo diário das fêmeas T. Os resultados da percentagem...
The present research aimed to elucidate which aspects of immune responses in Diatraea flavipennella are suppressed by the parasitoid Cotesia flavipes, thus, ensuring parasitism success. We investigated presence apoptosis fat body cells through TUNEL technique. According results, reduced levels nitric oxide and phenoloxidase activity were observed larvae parasitized for three days, total number hemocytes, after seven days. An increase plasmatocytes decrease spherulocytes numbers differential...
Coptotermes gestroi (Wasmann) é considerada uma das espécies mais destrutivas de cupins subterrâneos, por causar danos a edificações, à arborização urbana e culturas. Uma alternativa para o controle desse inseto pode ser uso agentes biocontroladores, como os fungos entomopatogênicos. Isaria (Persoon) tem sido indicado no térmitas inclusive do gênero Coptotermes. Dessa forma, presente trabalho teve objetivo selecionar isolados patogênicos ao cupim C. gestroi. Os insetos pulverizados com...
This work aimed to evaluate the effects of Metarhizium anisopliae on Diatraea flavipennella and investigate their immune response. Was observed effect M. against larvae D. sprayed at concentrations 103, 104, 105 conidia / mL, in which showed differences relative larval period, extending up 72.0 days treatment 25.0 control. The results for hemocytes revealed that most frequent cells when 105, 107 mL were prohemocytes, spherulocytes, plasmatocytes granulocytes relation adipohemocytes...
Os ácaros tetraniquídeos representam importantes pragas para diversas culturas agrícolas em todo o mundo. Durante a prospecção mudas de Erytrina velutina no distrito São Cristovão, Estado Sergipe, Brasil, ocorrência destes foi observada 15% das que foram levadas ao laboratório caracterização dos danos. As apresentavam sintomas redução e encarquilhamento do limbo. Foram coletados 100 indivíduos destas plantas, os quais montados lâminas microscopia identificação taxonômica. identificados como...
Coconut plantations are attacked by the lethal yellowing (LY), which is spreading rapidly with extremely destructive effects in several countries. The disease caused phytoplasmas that occur plant phloem and transmitted Haplaxius crudus (Van Duzee) (Auchenorrhyncha: Cixiidae). Owing to their phloem-sap feeding habit, other planthopper species possibly act as vectors. Here, we aimed at assessing seasonal variation Auchenorrhyncha community six dwarf coconut accessions. Also, assessed relative...
Nutritional and physiological interactions depend on the evolutionary history of host-parasitoid interaction considering that host’s regulation by parasitoid is species-specific. Cotesia flavipes Cameron was introduced in Brazil 70’s to be used control Diatraea sugarcane borer complex; however, flavipennella Box restricted Brazil. Thus, this study investigated possible nutritional changes hemolymph fat body, cytochemistry D. hemocytes parasitized flavipes. The levels nutrients were...
Biological control using the parasitoid Cotesia flavipes (Cam.) is one of main components in integrated management sugarcane moth borer Diatraea spp. Besides this parasitoid, entomopathogenic fungi Beauveria bassiana (Bals.) Vuill and Metarhizium anisopliae (Metsch.) Sorok. are used to pests, they can be found naturally parasitizing caterpillars. This study aimed evaluate effects M. B. on different developmental stages C. flavipennella (Box). The experiments were carried at laboratory with...
Entre os anos de 2005 e 2007, foram observados mensalmente danos causados por lagartas sobre as plantas Erythrina velutina (Willd.) no município São Cristovão, Sergipe, Brasil. As mudas com levadas ao laboratório, o objetivo caracterizar identificar a praga. Esta foi identificada como Agathodes designalis (Guenée), encontrada em 35% das 49% causando da base para ápice. Este é primeiro registro A. atacando E. Estado Brasil.

Resumo. O psilídeo, Diaphorina citri Kuwayama (Hemiptera: Sternorrhyncha: Liviidae), por ser vetor da bactéria causadora do Hunglongbing (HLB), tornou-se uma praga-chave dos citros no Brasil. Além citros, a planta ornamental conhecida como murta-de-cheiro, Murraya paniculata (L.) Jack, também é hospedeira psilídeo. presente trabalho teve objetivo estudar dinâmica populacional psilídeo em pomares de e o seu parasitismo murta-de-cheiro estado Sergipe, quarto maior produtor As avaliações foram...
Coconut trees of the cv. Green Dwarf Jiqui in Bahia, northeastern Brazil, that displayed hartrot symptoms were cut and inspected for presence insect vectors leaf axils. Eggs, nymphs adults Lincus lobuliger Breddin (Hemiptera: Pentatomidae), vector protozoan causing hartrot, collected together with an abundance predatory beetle Hololepta (Leionata) quadridentada (Olivier) (Coleoptera: Histeridae). In field, both placed a plastic container transport, predation L. eggs by histerid was observed....
Abstract The quarantine disease Lethal Yellowing (LY) is currently the main threat to coconut cultivation in Brazil. LY caused by phytoplasmas and transmitted Haplaxius crudus (Hemiptera: Cixiidae), although other planthoppers/leafhoppers could be involved. We assessed Auchenorrhyncha community composition on various hybrids, including association with parental nonparental dwarf accessions. were trapped 2016 between dry rainy seasons (March April), season (July August) (November December)....
