Aspects of the biology, behavior, and economic importance of Camponotus pennyslvanicus (Degeer) and Camponotus ferrugineus (Fabricius) (Hymenoptera: formicidae)
… factor in the decision to request control. Camponotus ferrugineus and C. pennsylvanicus are similar in their colony foundation and biology. C. ferrugineus required 54 days to produce the first brood and there were 18 workers, including one intermediate worker, in the first brood. Queens of …

A macro- and micro-evolutionary investigation of African Camponotus ants
Camponotus than the cytochrome oxidase II gene, based on almost all measures of phylogenetic utility. The primary hypothesis proposed to account for this observation is that these two mitochondrial genes are evolving under different evolutionary constraints. Specifically, the cytochrome oxidase II …

Charakterisierung intrazellulärer, bakterieller Endosymbionten im Mitteldarm von Ameisen der Gattung Camponotus
… im Mitteldarm von Ameisen der Gattung Camponotus beitrugen. Es wurden phylogenetische Untersuchungen mit Hilfe der 16S rDNA-Sequenzen der Symbionten und der Sequenzen der Cytochrom-Oxidase-Untereinheit I (COI-Sequenzen) ihrer Wirte durchgeführt, die zur näheren Klärung der Fragen zu …

Behavioural and physiological ecology of the Namib Desert dune ant, Camponotus detritus emery
The ecology of Camponotus detritus was examined over two years at six sites across the Namib Desert. This common species was found to fill an important role in the dune ecosystem as the major honeydew consumer, apparently limited chiefly by intraspecific competition for food. Each colony, …

Nutritional Ecology of the Carpenter Ant Camponotus pennsylvanicus (De Geer): Macronutrient Preference and Particle Consumption
… nutritional ecology of the black carpenter ant, Camponotus pennsylvanicus (De Geer) was investigated by examining macronutrient preference and particle consumption in foraging workers. The crops of foragers collected in the field were analyzed for macronutrient content at two-week intervals …

Hindgut secretions in <I> Camponotus pennsylvanicus </I> (De Geer) (Hymenoptera: Formicidae): attractants and nitrogenous excretory materials
… trail pheromone in the black carpenter ant, <I> Camponotus pennsylvanicus </I>, was investigated by presenting workers with crude or synthetic hindgut extracts to test for attractancy and trail-following behavior. Chemical analysis was used in conjunction with behavioral bioassays to detect and …

An investigation of the sociogenetic structure of the endemic fynbos ant, Camponotus klugii, via the use of microsatellites
Eusocial insects, in particular ants, demonstrate great variability in their sociogenetic structure with regards to colony organization, queen number, queen mating frequency, levels of relatedness and worker reproduction. Within this study I perform an analysis on two groups of ant nests of the …

Demography, cold hardiness, and nutrient reserves of overwintering nests of the carpenter ant Camponotus pennsylvanicus (De Geer) (Hymenoptera: Formicidae)
Overwintering nests of C. pennsylvanicus were dissected and censused. All castes were assayed for glycerol and for changes in nutrient reserves. Spring queens were collected at swarming and allowed to initiate nests. Queens were analyzed for nutrient reserves during the early stages of nest …

Effects of pine invasions on ground-dwelling ants on the southern slopes of the Swartberg Mountains
… 15 genera, were collected during the study. Camponotus was most species-rich genus (13 species), followed by Monomorium (7 species), Tetramorium (4 species) and Lepisiota (2 species), with 11 of the 15 genera each represented by a single species. No non-indigenous species were observed during …

Surveying house-infesting ants after 87 years: species identity and economic impact in central Illinois
… sessile (Say), Lasius alienus (Förster), Camponotus pennsylvanicus (DeGeer) and Solenopsis molesta (Say). In contrast, I found 9 species infesting houses in 2012-13 and the 4 most common were Tapinoma sessile(Say), Tetramorium caespitum (Linnaeus), Camponotus pennsylvanicus (DeGeer) and …

Pollination Biology of <i>Ailanthus altissima</i> (Mill.) Swingle (Tree-of-Heaven) in the Mid-Atlantic United States
… genera <i>Formica</i>, <i>Prenolepis</i>, and <i>Camponotus</i>. No major diurnal pattern was found for visitation of insect pollinators using instantaneous counts. The nectar composition, concentration, and amount of total sugars in the flowers of <i>A. altissima</i> and how these are related to …

Anting Behavior in Birds: Ant Selection and Effect of ant Chemistry on Feather Ectoparasites
… more often than from the Myrmicinae. <em>Camponotus, Lasius</em> and <em>Aphaenogaster</em> ants were preferred and <em>Pheidole</em> and <em>Crematogaster</em> ants were rejected. Preferred ants were significantly more active than ignored ants and lacked aggressive stinging and biting …

The impact of pine plantations and alien invertebrates on native forest and fynbos invertebrate communities in Table Mountain National Park
… IndVal, two ant species (Pheidole capensis and Camponotus bertolinii) were selected as ecological indicators of restoration progress in fynbos following clear-felling of pine. Ants similarly have application for monitoring in other Mediterranean-type ecosystems impacted by invasive pines.

Riqueza e diversidade de formigas (Hymenoptera : Formicidae) nos campos naturais paranaenses
… gêneros mais ricos foram Pheidole (67 espécies), Camponotus (25 espécies) e Solenopsis (19 espécies). Os resultados indicam que a composição da fauna de formigas é distinta entre as duas formações de campo do estado. As áreas do PEVV, PEG e PEC (Campos Gerais) apresentam uma composição de espécies …
