Feeding preference behaviour of Crytopermes cynocephalus Light and Coptotermes curvignathus Holmgren on twenty-eight tropical timbers
1985 - IRG/WP 1251
A study on the feeding preference behaviour of a dry-wood termite Cryptotermes cynocephalus Light and a subterranean termite Coptotermes curvignathus Holmgren on 28 species of tropical timbers has been conducted. The weight-loss of individual timber and the mortality of termite was·recorded after 5, 10, 15, 20 and 25 days of exposure. The results reveal that there are only five species among 28 s...

Notes on the resistance of tropical woods against termites
1985 - IRG/WP 1249
This paper deals with a descriptive account on the effect of experimental methods, matrix, species of termites, solid wood and wood extract on the resistance and repellency of woods against three species of termites, i.e. Cryptotermes cynocephalus Light; Coptotermes curvignathus Holmgren and Reticulitermes lucifugus (Rossi). Two methods of experiment were used, the Forced Feeding Test and the Feed...

Preference of the Formosan subterranean termite for wood previously damaged by conspecifics
1988 - IRG/WP 1338
In a laboratory choice test, groups of termites from five colonies of Coptotermes formosanus Shiraki were presented with wood blocks which had sustained previous termite damage: 1) by nestmates, 2) by conspecifics from another colony, 3) by another termite species, Reticulitermes virginicus Banks, and 4) no damage. Coptotermes formosanus preferred wood previously damaged by conspecifics over that ...

Variance in feeding on equivalent wood blocks by the Formosan subterranean termite (Coptotermes formosanus Shiraki)
1987 - IRG/WP 1325
We tested whether laboratory groups of Coptotermes formosanus Shiraki forage randomly when they are given 4 equivalent wood blocks, and whether group size affects variance of feeding on equivalent blocks. In all cases, foraging was not random, but, rather, the termites concentrated on a few preferred blocks. Group size did not affect this pattern of non-randomness. These data are useful for design...

Preference of swarming termites for various colored lights
1984 - IRG/WP 1238
The ability of the alates of the drywood termite Bifiditermes beesoni (Gardner) to discriminate ten different colored lights was studied. When an alternative choice of any of two colors was offered, the light-blue was preferred to all other tested colors by 97.7% of the alates. A lower degree of attractivity was found for some other colors and certain other colors were indistinguishable. Furthermo...

Preference of Reticulitermes flavipes (Kollar) for Southern Pine Blue-Stained Sapwood from Beetle-Killed Trees
2012 - IRG/WP 12-10763
Bark beetles and their associated Ophiostomatiod fungi are the major pests of pine forests in the southeastern USA, and termites are the major insect decomposers of dead trees and wood products in the southeastern USA. While both are the principal destructive insects of southern pine trees and southern pine lumber, respectively, no relationship between the two has apparently been reported in the ...

Laboratory and Field evaluation on Natural Resistance and Feeding Preference of Different Wood Species to Subterranean Termites (Isoptera: Rhinotermitidae, Termitidae) in Pakistan
2012 - IRG/WP 12-10769
The resistance of twenty four different woods to attack and damage by subterranean termite species Heterotermes indicola (Wasmann) and Coptotermes heimi (Wasmann) was evaluated by choice and no choic in laboratory and field trials. Mean wood mass loss was calculated for both laboratory and field trials results using Analysis of Variance (ANOVA). Mean percentage termite mortality was calculated fo...

Wood protection techniques and natural weathering: their effect on aesthetics and preference of people
2019 - IRG/WP 19-50351
Current research successfully contributes to improving wood protection techniques. However, the vast majority of research on preventing degradation of wood ignores a critical aspect of making successful products and processes – user selection of materials, which may largely depend on the aesthetical qualities. Wood treatments change the tactile and visual properties of wood substantially and the...
