Abstract:

 [Objectives]  To investigate the food preference of Reticulitermes chinensis and Coptotermes formosanus for wood of some common tree species in the Zhenjiang area, the influence of termites and wood species on termite feeding preferences and mortality were analyzed. This study provides a scientific basis for future termite control and prevention. [Methods]  The experimental design was a no-choice test designed to test feeding preferences and mortality of two termites species with respect to 7 different wood species, including Cinnamonum campora, Ginkgo biloba, Metasequoia glyptostrodoides, Salix babylonica, Magnolia grandiflora, Eriobotrya japonica and Pinus massoniana. The termites’ feeding preferences were determined by wood consumption rate, i.e. mg wood/gram of termite/day. The data were analyzed by multivariate analysis of variance. [Results]  The results show that both termite species and wood source had a significant effect on wood consumption rate and mortality. Among the tested 7 wood typesthe most preferred by R. chinensis were those of S. babylonica and P.massoniana woods, which had consumption rates of 31.46 and 30.59 mg/g body weight/day, respectively. For C. formosanus, the most preferred wood types were those of P. massoniana, M. glyptostrodoides, and G. biloba, with respective consumption rates of 26.53, 21.82 and 21.81 mg/g body weight/day. Two termite species showed significant differences in wood consumption rates when feeding on the wood of G. biloba, S. babylonica and M.grandiflora, but no significant differences were apparent with respect to wood from the other four tree species. [Conclusion]  This investigation shows that both wood consumption rate and termite mortality are significantly influenced by termite and tree species. Two termite species had significant preferences for the wood of different trees, but in general, the lowest termite mortality was observed when termites fed on P. massoniana wood.
