Abstract

As part of an investigation into the potential unintended ecological impacts of transgenic trees, invertebrates were sampled from a field trial of transgenic Pinus radiata D. Don carrying the expressed antibiotic resistance marker gene neomycin phosphotransferase II (nptII) along with other genes known to affect reproductive development in plants and from nontransformed control trees. Invertebrate species abundance, richness, diversity, and composition were measured and compared among trees of five different transclones and nontransformed isogenic control trees. Invertebrates were sampled at six-monthly intervals over a period of 2 yr. In total, 19,162 individuals were collected comprising 279 invertebrate recognizable taxonomic units. Total invertebrate populations as well as populations of herbivorous lepidopteran larvae and Hemiptera were compared among transgenic and control trees. The results show that the transclones had no significant unintended influence on species abundance, richness, diversity, or composition for all populations investigated.
