Foraging behaviour and the diurnal and seasonal foraging periodicity of the southern African snouted harvester termite, Trinervitermes trinervoides (Sjöstedt), are described. The termite usually foraged during summer nights when ambient temperatures were 10–14 °C. Foraging occurred at temperatures between 13–25 °C under laboratory conditions. A foraging party emerging from a single hole harvested over an area of approximately 0.78 m2. A colony exploited a total area of approximately 214 m2 and… Expand
The Role of the Harvester Termite, Trinervitermes trinervoides (Termitidae: Nasutitermitinae) in Semi-Arid Grassland Ecosystems of South Africa: Abundance, Biomass and Grass Consumption
TLDR
The impact of T. trinervoides within well-managed grassland ecosystems where the litter-feeding species forman important link in the food chain, is chiefly beneficial and far outweighs its harmful effects which tend to be associated with degraded, overgrazed grassland and drought. Expand
Does Thermoregulation Occur in the Mounds of the Harvester Termite, Trinervitermes trinervoides (Sjöstedt) (Isoptera: Termitidae)?
TLDR
These T. trinervoides colonies were unable to build subterranean nests due to the bedrock layer occurring close to the soil surface, but achieved constant core temperatures through the insulating properties of the mound. Expand
The Role of the Harvester Termite, Trinervitermes trinervoides (Termitidae: Nasutitermitinae), in a Semi-Arid Grassland Ecosystem in South Africa: Nest Populations and Caste Composition
TLDR
No clear pattern of changing proportions of soldier or worker larvae emerged that could be linked to seasonal fluctuations in activities such as foraging, but a number of different nymphal instars were present in the nest simultaneously. Expand
The ecology and foraging behaviour of the harvester termite, Baucaliotermes hainesi in semi-arid grasslands in the northwestern interior of South Africa
TLDR
It is found that Baucaliotermes hainesi is strictly a nocturnal species and that temperature is the most important abiotic determinant of foraging activity, and that B. hainei can significantly reduce grass cover, particularly in overgrazed areas and in dry years. Expand
Plant shade enhances thermoregulation of internal environments in Trinervitermes trinervoides mounds.
Microhabitats may be crucial in buffering organisms from temperature extremes, particularly given increases in maximum temperature associated with global climate change. For example, thermoregulationExpand
Foraging behaviour and sensory ecology of the bat-eared fox (Otocyon megalotis)
TLDR
Foxes may be able to exploit the temporal structure of natural noise to overcome foraging challenges imposed or may simply modify their foraging behaviour to avoid the effects of masking noise. Expand
Long-term livestock grazing increases the recruitment success of epigeal termites: insights from a >75-year grazing experiment in the Karoo, South Africa
TLDR
It is suggested that livestock grazing provides additional forage resources for termites through litter breakup and dung production, leading to greater mound recruitment and thus densities, whilst allowing mounds to achieve greater maximum size. Expand
Trail Communication Regulated by Two Trail Pheromone Components in the Fungus-Growing Termite Odontotermes formosanus (Shiraki)
TLDR
The foraging process and trail pheromones of the fungus-growing termite Odontotermes formosanus were systematically studied and monitored in real-time using a combination of techniques, including video analysis, solid-phase microextraction, gas chromatography coupled with either mass spectrometry or an electroantennographic detector, and bioassays. Expand
Luminal hindgut bacterial diversities of the grass and sugarcane feeding termite Trinervitermes trinervoides
TLDR
Tmite hindgut bacterial diversity did not cluster according to diet but termite phylogeny; this suggests diet was not the main determinant of microbial diversity, and bacterial diversity, substrate preference. Expand
Farmers' knowledge and perceptions of termites as pests of yam (Dioscorea spp.) in Central Benin
TLDR
Application of chemicals was the most commonly reported control method, followed by destruction of termite nest, and application of botanical extracts, and according to farmers, the high multiplication rate oftermites is the most important constraint in managing the issue of termites in yam. Expand

Food preferences in laboratory colonies of the harvester termite, Trinervitermes trinervoides (Sjöstedt) (Termitidae: Nasutitermitinae)
TLDR
The harvester termite, Trinervitermes trinervoides preferred grass litter to all the other plant material offered in laboratory choice trials, but the chemical constituents of the food seemed to be less important. Expand
A quantitative study of seasonal foraging by the grass harvesting termite, Trinervitermes geminatus (Wasmann), (Isoptera, Nasutitermitinae) in Southern Guinea savanna, Mokwa, Nigeria
TLDR
The quantity of grass removed by T. geminatus, amounting to only 3.1% of the net primary production, did not appear to be economically significant in this locality. Expand
THE INFLUENCE OF FOOD ON TRAIL‐LAYING AND RECRUITMENT BEHAVIOUR IN TRINERVITERMES BETTONIANUS (TERMITIDAE: NASUTITERMITINAE)
In a laboratory foraging situation food, when detected, stimulates workers of Trinervitermes bettonianus (Sjöst) to lay stronger recruitment trails and to motivate nestmates to mass foraging. SingleExpand
FORAGING BEHAVIOUR AND FEEDING HABITS IN FIVE SPECIES OF TRINERVITERMES IN WEST AFRICA
TLDR
Foraging habits of five species of Trinervitermes occurring in W. Africa indicate that selective foraging of grass species may occur, and adaptation to differing conditions in each species is suggested. Expand
High temperature tolerance in two species of subterranean termites in the Sonoran Desert in Arizona.
TLDR
This brief investigation of the foraging activity and behavior of Heterotermes aureus and Gnathamitermes perplexus reveals that these termites occasionally work at temperatures close to 50°C, with moisture also having a regulatory effect in upper soil levels. Expand
A study of the food eaten by a field population of the Harvester termite, Hodotermes mossambicus (Hagen) and its relation to population density
A crash in a population of Hodotermes mossambicus (Hagen) was observed after a prolonged drought during 1966. Virtually no recovery in numbers has taken place since that time. The crash was probablyExpand
The underground passages and storage pits used in foraging by a nest of the termite Macrotermes michaelseni in Kajiado, Kenya
Part of the system of underground passages and storage pits used in foraging by a nest of Mucrofermes michaelseni was excavated and is described in detail, and an attempt is made to quantify it.Expand
Mound population movements and fluctuations inTrinervitermes ebenerianus Sjöstedt (Isoptera, termitidæ, nasutitermitinæ)
TLDR
Fluctuations in the population density and percentage of young stages are related to a hypothetical annual cycle of activity depending on climatic conditions, andDiurnal changes in mound populations were detected, but these cannot readily be related to Climatic conditions. Expand
Nest and soil populations of Trinervitermes spp. with particular reference to T. geminatus (Wasmann), (Isoptera), in Southern Guinea savanna near Mokwa, Nigeria
TLDR
Soil and mound sampling in primary and secondary savanna showed that although T. geminatus is a mound inhabiting species, two thirds of the mound plus soil population was outside the mounds, indicating that these two species were primarily subterranean. Expand
Nest structure and size distribution in the genusTrinervitermes (Isoptera, Termitidæ, Nasutitermitinæ) in West Africa
TLDR
It is suggested that in the population examined the mean annual increment of mounds is four to five inches diameter; colony expansion is probably by the erection of supplementary mounds after the primary mounds reach three or four years of age. Expand
