Abstract  Coptotermes gestroi and Heterotermes tenuis have been described as important urban pests in Brazil. The establishment of control technologies using baits that consider the social behavior of termites requires a better knowledge of their foraging behavior. Thus, this study analyzed the feeding behavior of these species with three different forms of food placement: food on the surface of a substrate and food either partially or completely buried in the substrate. Experimental arenas… 

Foraging in subterranean termites (Isoptera: Rhinotermitidae): how do Heterotermes tenuis and Coptotermes gestroi behave when they locate equivalent food resources?

It is concluded that foragers of either species do not concentrate their efforts on the consumption of only one food resource when they are able to reach multiple cellulosic sources simultaneously and the data concerning tenacity tests suggest that there is a chronologic priority of consumption in relation to the discovery of available food sources.

Clay preference and particle transport behavior of Formosan subterranean termites (Isoptera: Rhinotermitidae): A laboratory study

The biological significance of clay on C. formosanus was investigated and significantly more termites aggregated in chambers where clay blocks were provided, regardless of colony group, observation period, or nutritional condition.

The Coptotermes gestroi aldo–keto reductase: a multipurpose enzyme for biorefinery applications

The data indicated that additive enzymatic activity could be mediated by reactive oxygen species because CgAKR-1 could produce hydrogen peroxide, which provided a basis for the development and application of integrative and multipurpose enzymes in the bioethanol production chain.

Filling Voids in Subterranean Termite (Blattodea: Rhinotermitidae) Bait Stations with Soil or Clay Improves Preference and Performance

Subterranean termites often transport soil into bait stations, and adding soil or clay material in the bait may affect preference and performance of termites, and may contribute to the improvement of termite-baiting technologies.



Impacts of Soil Moisture Level on Consumption and Movement of Three Sympatric Subterranean Termites (Isoptera: Rhinotermitidae) in a Laboratory Assay

Results from consumption and location data show unique patterns among species, and illustrate species-specific variation in feeding location and nesting preference in response to moisture, which contribute to the overall understanding of midwestern Reticulitermes termites.

Formosan Subterranean Termite (Isoptera: Rhinotermitidae) Wood Consumption and Worker Survival as Affected by Temperature and Soldier Proportion

On average, termites had a significantly higher survival rate when the initial soldier proportion was <20%, and soldier caste development was at its highest at 30°C, and when treatment started with no soldiers in the colony.

Preference for moist wood by the Formosan subterranean termite (Isoptera: Rhinotermitidae)

The data imply that damp wood in buildings is especially vulnerable to C. formosanus and that bait blocks for remedial control of this pest should have high moisture content.

Food location and discrimination by subterranean termites (Isoptera: Rhinotermitidae).

Abstract Tunnel construction by Coptotermes formosanus Shiraki is initially random, with tunnels radiating outwardin a uniform circular distribution from the point of origin. The degree of branching

Biotic and Abiotic Influences on Foraging of Heterotermes aureus (Snyder) (Isoptera: Rhinotermitidae)

A new statistical model was developed to analyze the effect of distance between food items on termite foraging behavior, and the pattern of attack by termites was generally consistent with the null hypothesis that termites forage randomly with respect to distance between potential food sources.

Comparison of Laboratory Methods for Estimating Wood Consumption Rates by Coptotermes formosanus (Isoptera: Rhinotermitidae)

Three methods of calculating wood consumption rates by laboratory groups of the termite, Coptotermes formosanus Shiraki, were compared and confirmed that a model which assumed no termite mortality during the feeding trial significantly underestimated wood consumption.

Influence of Different Substrate Moistures on Wood Consumption and Movement Patterns of Microcerotermes crassus and Coptotermes gestroi (Blattodea: Termitidae, Rhinotermitidae)

Moisture content of sand affected wood consumption and influenced termite distribution across a moisture gradient for M. crassus and C. gestroi, and showed a similar distribution pattern of association with particular moisture levels.

The taxonomic status of pest species of Coptotermes in Southeast Asia: resolving the paradox in the pest status of the termites, Coptotermes gestroi, C. havilandi and C. travians (Isoptera: Rhinotermitidae).

Coptotermes gestroi occurs from Assam through Burma and Thailand to Malaysia and the Indonesian archipelago, and has been introduced into other geographic regions, and is often intercepted outside its range in cargo onboard ships and sailing vessels, which is a likely mechanism for its spread to new geographical areas.

A review of subterranean termite control practices and prospects for integrated pest management programmes

The benefits of the monitoring--baiting programme over conventional soil treatment are a reduction in pesticide applied per unit and the elimination of termite populations near structures, resulting in the reduction of liability and damage potential.
