Abstract 1 The citrus leafminer (CLM) Phyllocnistis citrella Stainton (Lepidoptera: Gracillariidae) is a serious pest in most citrus‐growing regions of the world. influence leaf length, species or variety, colour tone and temperature on CLM oviposition was studied from field observations laboratory experiments. spatial distribution eggs leaves also examined. Field data were obtained 1100 samples collected eastern Spain for 7 years. 2 Significant differences rate found among ‘no choice’ This...
Atta grass-cutting ants (Formicidae: Myrmicinae: Attini) are found in the Cerrado biome and build giant nests with hundreds or thousands of large chambers. We assessed for bisphaerica whether total volume fungus chambers other nest parameters grow at close similar proportions to worker numbers colony. Data on garden biomass, population, external area, number entrance holes, chambers, volume, depth were obtained during colony growth/nest development. Our results reveal that chamber increased...
Pest populations in a given agroecosystem may be influenced by several abiotic and biotic variables, including the host plant cultivar.We compared population fluctuation of pest mites twenty citrus scion cultivars grafted on Rangpur lime (Citrus limonia).Adults rust mite Phyllocoptruta oleivora (Acari: Eriophyidae), Texas Eutetranychus banksi Tetranychus mexicanus Tetranychidae) were monthly counted each cultivar from April 2011 to February 2013 Sergipe state, northeastern Brazil.Larger E....
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...
Abstract The sweet potato whitefly, Bemisia tabaci MED (Gennadius) (Hemiptera: Aleyrodidae), is highly harmful to solanaceous crops. use of essential oils (EOs) promising for the management several insect pests, promoting both lethal and sublethal effects. This study aimed evaluate effects concentrations Pelargonium graveolens L'Her (Geraniaceae) EO on feeding behavior B. tomato plants ( Solanum lycopersicum L., Solanaceae). For this research, electrical penetration graph (EPG) technique was...
Avaliaram-se os efeitos da injeção epidural de amitraz (0,4mg/kg), xilazina (0,05mg/kg) ou dimetil sulfóxido 10% (5,0ml) sobre a freqüência cardíaca (FC), pressão arterial sistólica (PAS), respiratória (FR), motilidade ruminal (MR), temperatura retal (TR), altura cabeça (AC) e latência das respostas estímulos nociceptivos nas regiões coxa (LECC) coroa do casco (LRRM) vacas. Houve diminuição FC MR nos grupos amitraz. O tratamento com resultou em alterações na FR, PAS AC. LECC LRRM foram...
Abstract Claustral foundation of nests by Atta sexdens Forel (Hymenoptera: Formicidae) involves great effort its queens, solely responsible for the cultivation fungus and care her offspring at this stage. The minimum workers, after 4 months, open access to external environment foraging plants cultivate symbiotic fungus, which decomposes plant fragments produces gongilidea nodules as food individuals in colony. Colony gas exchange decomposition organic matter underground ant generate carbon...
Queens of Atta sexdens Forel (Hymenoptera: Formicidae) face biotic and abiotic environmental factors in the environment while establishing their nests. Biotic such as predation, microbial pathogens, successful symbiotic fungus regurgitation, excavation effort radiant sunlight, temperature, density, soil moisture exert selection pressures on ant queens. temperature solar irradiation affect survival initial colony differently, different environments field. leaf-cutting A. sexdens, were...
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...
Atta capiguara grass-cutting ants are commonly found in the Cerrado biome, open fields. Although build giant nests, little has been elucidated about this building pattern and when chambers tunnels emerge. The present study describes nest architecture development of A. from data on 31 cement-molded nests. nests grow with increases number fungus emergence increase waste foraging tunnels. structural growth first year a half age (18 months) is vertical, soil profile. After 18 months, sideways...
O ácaro-da-necrose, Aceria guerreronis Keifer (Acari: Eriophyidae), é a principal praga do coqueiro no Brasil. controle químico com acaricidas amplamente utilizado para controlar essa praga. Frente aos diversos problemas sociais, econômicos e ambientais ocasionados pelo uso indiscriminado de acaricidas, são necessárias alternativas ambientalmente viáveis o dessa como fungos entomopatogênicos. Assim, este trabalho objetivou estimar letalidade fungo Beauveria bassiana (Bals.)Vuill....
Abstract The habitat choice of nest sites by founding queens leaf‐cutting ants varies with abiotic factors such as temperature, soil density, and humidity. In this study, we tested the hypothesis that density moisture affect excavation effort (i.e., period, excavated amount, initial depth, chamber volume, mortality) in ant Atta sexdens (L.) (Hymenoptera: Formicidae). Queens were placed experimental areas three natural soils Brazil varying content. was collected, dried, weighed, digging queen...
