Abstract

We investigated the impact of watermelon grafted onto Cucumber Gren Mottle Mosaic Virus(CGMMV)-resistant transgenic watermelon rotstock on insects as non-target organisms in a greenhouse in2005. We quantitatively collected insect assemblages living on leaves and flowers, and we used sticky traps to(Aphis gossypii Glover) on watermelon leaves and western flower thrip (Frankliniella occidentalisTrybom) onwatermelon male flowers, betwen CGMMV-resistant transgenic watermelon (TR) and non-transgenic water-melon (nTR). Non-parametric multidimensional scaling (NMS) ordination verified that insect assemblages onleaves and sticky traps were different between TR and nTR (P < 0.05). The insect assemblages on male flowerswere not statistically significant. Multi-response permutation procedures proofed our esults from NMS results (P> on leaves and sticky traps, but watermelon male flowers do not show an adverse effect. Further research isrequired to assess the ffect of TR on the aphid and western flower thrip. Life table experiments might supportthe specific reason for the adverse effects from leaf assemblages. Assessment of non-target impacts is anessential part of the risk assessment of non-target insects for the impact of transgenic organisms.
