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...
Mutual use of trail-following chemical cues by a termite host and its inquiline
Cristaldo, Paulo Fellipe; DeSouza, Og; Krasulová, Jana; Jirošová, Anna; Kutalová, Kateřina; Lima, Eraldo Rodrigues; Šobotník, Jan; Sillam-Dussès, DavidTermite nests are often secondarily inhabited by other termite species ( = inquilines) that cohabit with the host. To understand this association, we studied the trail-following behaviour in two Neotropical species, Constrictotermes cyphergaster (Termitidae: Nasutitermitinae) and its obligatory inquiline, Inquilinitermes microcerus (Termitidae: Termitinae). Using behavioural experiments and chemical analyses, w...
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...
Nest-sharing among a termite host and its obligatory inquiline
Cristaldo, Paulo FellipeCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; Interações simbióticas ocorrem em todos os grupos de organismos. Este tipo de interação é frequentemente observada em ninhos de insetos socias, no qual a espécie que coabita o ninho junto com o hospedeiro é geralmente outra espécie eusocial. Especificamente para cupins (Isoptera), os mecanismos envolvidos nesta interação permanecem abertos à investiga...
Mecanismos de defesa em ninhos de cupins (Insecta: Isoptera)
Cristaldo, Paulo FellipeCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; Termites present an elaborated defense system, but their nests are often invaded by a variety of organisms. The mechanisms that allow the invasion in termite nests are not elucidated. So, the objective of this dissertation was to understand the mechanisms of defense in termite nests. To do so, hypothesized that system failures defense may be due to in...
