Podisus nigrispinus Dallas (Heteroptera: Pentatomidae), released in biological control programs, is a predator of Lepidopteran and Coleopteran species. Lemongrass essential oil its constituents can be toxic to this natural enemy. The major lemongrass are neral (31.5%), citral (26.1%), geranyl acetate (2.27%). Six concentrations were applied the thorax P. nymphs adults. walking respiratory behavior third-instar nymphs, treated with at LD
Abstract Bioinsecticides and transgenic plants, based on Bacillus thuringiensis (Bt) toxins are important when managing Anticarsia gemmatalis Hübner (Lepidoptera: Noctuidae), a soybean defoliator pest. The interaction of these with the caterpillar’s midgut cells determines their efficacy as an insecticide. objective was to evaluate toxicity B. , subsp . kurstaki strain HD-1 cytopathological changes mediated by bacterial in A. caterpillars. Insecticidal determined calculating lethal...
Abstract Entomopathogenic nematodes (EPNs) (Steinernematidae and Heterorhabditidae) can control pests due to the mutualistic association with bacteria that kill host by septicemia make environment favorable for EPNs development reproduction. The diversity of in Brazilian soils requires further study. identification EPNs, adapted environmental climatic conditions cultivated areas is important sustainable pest suppression integrated management programs agricultural Brazil. objective was...
Summary The plant availability of phosphate applied to calcareous soils is affected by precipitation and adsorption reactions, the relative significance which not well known. We used extended P‐sorption curves obtained at addition rates up 340 mmol P kg −1 soil examine contribution 24 Spanish Vertisols Inceptisols. Adsorption was dominant 1 day small (10–35 ). With increasing clay Fe Al oxides contents soil, more sorbed before sorption curve bent upwards, as a result Ca precipitation....
The Atlantic Forest is one of the most threatened biodiversity hotspots and environmental impacts has made its landscape fragmented heterogeneous. heterogeneity fragments a challenge for characterization quantification forest resources, such as stock biomass carbon. Methodologies based on remote sensing have been used, to improve these estimates without compromising execution costs. objective was estimate, with high spatial resolution passive sensing, aboveground carbon in different...
Thaumastocoris peregrinus Carpintero and Dellape (Hemiptera: Thaumastocoridae) is a sap-sucking insect that has become major pest of eucalypts. The entomopathogenic fungi Beauveria bassiana (Bals.-Criv.) Vuill. Metarhizium anisopliae (Metsch.) Sorokin have the potential to control pests. This study evaluated susceptibility T. two commercial products based on conidia B. M. anisopliae. were sprayed onto adults at concentration 1 × 108 mL−1 evaluate their pathogenicity conidial production...
Meloidogyne enterolobii , reported in different regions of Brazil, is a polyphagous nematode parasitising plants resistant to other root-knot species. This study evaluated the resistance six cultivars Avena sativa seven Triticum aestivum and 13 hybrids Sorghum bicolor M. . The experiment was conducted glasshouse. soil autoclaved infested with 5000 eggs tomato ‘Rutgers’ used as susceptible standard this nematode. indices galls, egg masses, reproduction factor were 60 days after inoculation....
Efficient strategies to control the bronze bug Thaumastocoris peregrinus Carpintero and Dellapé (Hemiptera: Thaumastocoridae) are unavailable, but Cleruchoides noackae Lin Huber (Hymenoptera: Mymaridae) parasitizes eggs of this pest. The parasitism number parasitoids that emerged from T. were evaluated in laboratory pest collected field an area approximately 2 ha. Collections done 1 yr after first release C. check for establishment parasitoid eucalyptus plantations Minas Gerais State,...
spp. are the most economically important species of plant-pathogenic nematodes. Plant resistance and crop rotation main nematode management methods. Thus, objective was to evaluate seven wheat genotypes, five oat ten sorghum hybrids, three sorghum-sudangrass genotypes
Tetranychus ludeni damages the sweet potato. Pest development can vary between plant genotypes. The objective was to identify preference of for Ipomoea batatas genotypes, from germplasm bank at Universidade Federal dos Vales do Jequitinhonha e Mucuri (UFVJM). Natural infestations this mite were observed on 54 potato genotypes in potted, a greenhouse. Three mite-infested leafs each genotype collected and analyzed. red showed different population density rate BD 29 found be highly susceptible,...
O objetivo deste trabalho foi avaliar os parâmetros genéticos das características agronômicas e de tolerância ao florescimento precoce onze cultivares alface, bem como verificar a existência associação entre as características. experimento realizado em ambiente protegido, delineamento blocos acaso, com quatro repetições doze plantas por parcela. Quarenta cinco dias após o transplantio mudas, foram mensuradas seguintes características: massa matéria fresca total "comercial" da parte aérea,...
Summary We report on the foraging behavior of Polybia scutellaris (White) (Hymenoptera: Vespidae) and damage it causes to fruit Syzygium jambos (L.) Alston (Myrtaceae). Of 32 wasps monitored, 26 visited ground 6 branches. Foraging was most frequent in late morning early afternoon. Sumario (Write) preda insetos pragas, porem pode danificar cascas de frutos (Myrtaceae), tornando-os comercialmente inviaveis. Trinta e dois individuos dessa vespa foram observados, visitando amadurecidos no solo...
The blue gum chalcid, Leptocybe invasa Fisher & LaSalle (Hymenoptera: Eulophidae), causes galls on Eucalyptus spp. leaf midribs, petioles and stems. Biological aspects need to be studied assist in developing management strategies maintain this insect the laboratory rear parasitoid Selitrichodes neseri Kelly La Salle Eulophidae) that depends having a supply of seedlings infested by L. invasa. We evaluated longevity survival individual non reproductive females fed with six different diets...
Abstract Insecticides are the main method of controlling lepidopteran pests eucalyptus plantations and those selective to natural enemies, such as endoparasitoid Palmistichus elaeisis Delvare et LaSalle (Hymenoptera: Eulophidae), preferable. The objective this study was evaluate selectivity effects on biological parameters insecticide deltamethrin, registered for control defoliator caterpillars eucalyptus, parasitoid P. aiming rational use its compatibility with parasitoids. experiment in a...
El cultivo del litchi, Litchi chinensis, tiene gran popularidad en el mercado internacional. ácaro Aceria litchii (Eriophyidae), es una de las principales plagas este cultivo, se alimenta hojas, sobre todo la parte inferior plantas que forman eríneos. objetivo esta revisión presentar los métodos control y proponer técnicas manejo sistema producción integrado L. chinensis. Se detectaron infestaciones A. huertos Brasil 2008 uso insecticidas químicos principal método plaga. La combinación...
Hormonal herbicides, used in pastures, can suffer drift and reach forests. The sensitivity potential phytoremediation of native species to herbicide residues should be evaluated. objective this study is evaluate the initial development Atlantic Forest tree soil contaminated with hormonal herbicides. experiment was conducted a greenhouse 4 x 8 factorial scheme. first factor had control Tordon® three doses (0.166, 0.333 0.666 L ha−1) second consisted forest Anadenanthera colubrina (Vell.),...
