Screening of two plant-derived extracts from Sri Lanka for their potential to control the subterranean termite Coptotermes formosanus

  • The tropical environment of Sri Lanka accelerates bio-deterioration of cultural objects. Termites are one of the most damaging insect pests destroying the cellulose components of historical artifacts. Herbal extracts obtained from resin of Vateria copallifera (Retzius) Alston and seeds of Madhuca longifolia (Konig) Macbride have been used for centuries to preserve e.g. palm leaf manuscripts from insect attack. Herbal extractions of these traditional products for palm leaf manuscript were tested for their effect against the termite species Coptotermes formosanus Shiraki, 1909. Natural and artificial aged herbal extractions were tested to obtain a repellent index. Resin oil of V. copallifera caused slightly higher repellencies than M. longifolia. Artificially aged samples produced lower repellencies than naturally aged samples. The results indicate that the active ingredients are volatile. The potential for barrier treatment was tested only with V. copallifera. Tunnelling-behavior of C.The tropical environment of Sri Lanka accelerates bio-deterioration of cultural objects.

Tunnelling-behavior of C. formosanus workers through sand in the presence of V. copallifera resin oil was largely reduced.zeige mehrzeige weniger
