Acaricidal properties of vetiver essential oil from Chrysopogon zizanioides (Po...
Campos, Roseane Nunes de Santana; Lima, Cecília Beatriz Nascimento; Oliveira, Alexandre Passos; Araújo, Ana Paula Albano; Blank, Arie FitzgeraldTicks are arthropods widely distributed in tropical and subtropical regions, which can transmit infectious agents also responsible for zoonoses. Excessive use of conventional acaricides has resulted in the onset of drug resistance by these parasites, thus the need to use alternative methods for their control. This study evaluated the acaricidal activities of Chrysopogon zizanioides (vetiver) essential oils cont...
Sub-lethal effects of essential oil of Lippia sidoides on drywood termite Crypt...
Santos, Abraão Almeida; Oliveira, Bruna Maria Santos de; Melo, Carlisson Ramos; Lima, Ana Paula Santana; Santana, Emile Dayara RabeloThe drywood termite Cryptotermes brevis (Walker, 1853) (Kalotermitidae) is one of the most important wood structural pest in the world. Substances from the secondary metabolism of plants (e.g., essential oils) have been considered an environmentally safer form of control for urban pests, such as termites. In the present study, we analyzed the lethal and sub-lethal effects of essential oil of Lippia sidoides and...
Allometric scaling of patrolling rate and nest volume in Constrictotermes cyphe...
DeSouza, Og; Araújo, Ana Paula Albano; Florencio, Daniela Faria; Rosa, Cassiano Sousa; Marins, Alessandra; Costa, Diogo AndradeStructural and functional traits of organisms are known to be related to the size of individuals and to the size of their colonies when they belong to one. Among such traits, propensity to inquilinism in termites is known to relate positively to colony size. Larger termitaria hold larger diversity of facultative inquilines than smaller nests, whereas obligate inquilines seem unable to settle in nests smaller th...
Essential oil of Aristolochia trilobata: synthesis, routes of exposure, acute t...
Oliveira, Bruna Maria Santos de; Melo, Carlisson Ramos; Alves, Péricles Barreto; Santos, Abraão Almeida; Santos, Ane Caroline CelestinoPlants of the genus Aristolochia have been frequently reported as important medicinal plants. Despite their high bioactive potential, to date, there are no reports of their effects on leaf-cutting ants. Therefore, the present study aimed to evaluate the insecticidal activity of the essential oil of Aristolochia trilobata and its major components on Atta sexdens and Acromyrmex balzani, two species of leaf-cuttin...
Diet segregation between cohabiting builder and inquiline termite species
Florencio, Daniela Faria; Marins, Alessandra; Rosa, Cassiano Sousa; Araújo, Ana Paula Albano; Silva, Ivo Ribeiro; DeSouza, Og; Cristaldo, Paulo FellipeHow do termite inquilines manage to cohabit termitaria along with the termite builder species? With this in mind, we analysed one of the several strategies that inquilines could use to circumvent conflicts with their hosts, namely, the use of distinct diets. We inspected overlapping patterns for the diets of several cohabiting Neotropical termite species, as inferred from carbon and nitrogen isotopic signatures...
Por que existem recursos potenciais não explorados pelos cupins (Insecta: Isopt...
Araújo, Ana Paula AlbanoCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; O entendimento dos padrões de utilização do recurso alimentar pode contribuir para o conhecimento dos mecanismos que regulam a estrutura das comunidades. A despeito de apresentarem grande importância econômica e ecológica, pouco se sabe sobre os padrões de forrageamento dos cupins. Por se alimentarem de celulose, um recurso abundante na natureza, os c...
Impact of resource availability on bee diversity.
Araújo, Vinícius Albano; Araújo, Ana Paula Albano; Itabaiana, Yasmine AntoniniResource availability is an important predictor of abundance and species richness. In this paper we veri!ed why there is local variation in bee diversity testing the hypothesis that bee species richness and abundance will increase with increasing resource availability. Resource availability was considered here as the number of "owering plants and the number of plant species. Sampling was carried out at two site...
Óleos essenciais de plantas medicinais e aromáticas no controle do carrapato Rh...
Campos, Roseane Nunes de Santana; Bacci, Leandro; Araújo, Ana Paula Albano; Blank, Arie Fitzgerald; Arrigoni-Blank, Maria de FátimaArtigo de revisão; O carrapato bovino Riphicephalus microplus (Acari: Ixodidae) constitui um dos grandes problemas enfrentado pelos pecuaristas de várias partes do mundo. No Brasil este ectoparasita causa grandes prejuízos à bovinocultura devido ao processo de hematofagia e pela transmissão de agentes patogênicos nos animais hospedeiros. Diante dessa situação os produtores normalmente aplicam carrapaticidas org...
Insetos indutores de galhas da porção sul da Cadeia do Espinhaço, Minas Gerais,...
Carneiro, Marco Antonio Alves; Borges, Rafael Augusto Xavier; Araújo, Ana Paula Albano; Fernandes, Geraldo Wilson AfonsoInsetos indutores de galhas na porção sul da Cadeia do Espinhaço, Minas Gerais, Brasil. A riqueza de insetos galhadores é maior nas latitudes intermediárias em hábitats quentes e com vegetação esclerófila sob estresse hídrico e de nutrientes. Em regiões tropicais, os campos rupestres são indicados como hábitats ricos em espécies de insetos galhadores. Neste trabalho, foram descritas as galhas induzidas por inse...
Efeitos do sexo, do vigor e do tamanho da planta hospedeira sobre a distribuiçã...
Araújo, Ana Paula Albano; Carneiro, Marco Antonio Alves; Fernandes, Geraldo Wilson AfonsoEffects of gender, vigor and size of the host plant Baccharis pseudomyriocephala Teodoro (Asteraceae) on gallinducing insect distribution. Several hypotheses have been proposed to explain the patterns of host plant utilization by herbivorous insects in natural communities. We tested four hypotheses aiming to understand the pattern of attack by gallinducing insects on the dioecious shrub, Baccharis pseudomyrioce...
