- Abstract
AbstractThe marine borer Limnoriaingests essential wood components including the extractives the wood contains. Some extractives may confer borer resistance on certain timbers. Feeding by Limnoriacorrelates with the rate of production of faecal pellets. The faecal pellet production rate and mortality on over 40 test timbers and non-resistant Pinus sylvestrissapwood was measured over 15 days. By placing animals in leachate from wood and with wood in flowing seawater, the effects of leaching-resistant and water-soluble compounds were measured. Some previously untested timbers affected Limnoriaas strongly as timbers reputed for durability in marine construction. Wood of Minquartia guianensis, Nectandra rubraand Bruguiera gymnorhizacaused high mortality, and pellet production on them was less than 10% of production on P. sylvestris. Suppressed feeding rates, but with no heavy mortality, were observed on known durable species such as Chlorocardium rodiei, Dicorynia guianensis, Lophira alataand Nauclea trillesii, but also on Cynometra ananta, Distemonanthus benthamianus, Enterolobium schomburgkii, Goupia glabra, Hymenaea courabil, Mammea africana, Shoreasp. and Sacoglottis guianensis. Leachate from B. gymnorhiza, G. glabra, H. coubaril, N. rubraand Shoreasp. caused high mortality. These short-term bioassays thus detected clear differences between wood species in their resistance to Limnoriathat matched findings from long-term marine trials, while indicating new species worthy of detailed testing.
