Insect pests can strongly influence the economic outcome of short rotation coppices. Chemical control is often complicated due to the
height of the trees and the prohibition of aerial spraying of pesticides by the German legal framework. Therefore, non-chemical measures to reduce the populations of pest insects are in focus of current research. Habitat manipulation is one key element to enhance biological control with the aim to supress the damage through pest species below the economic injury level. As an example, the influence of the presence of different food sources on longevity and fertility on the pupal parasitoid Schizonotus sieboldi (Pteromalidae), an important antagonist of the leaf beetle Chrysomela populi, will be presented. We found that the longevity of female S. sieboldi individuals can be prolonged from 4 ± 1 days without food to 31 ± 12 days with Galium album, which was proved to be the best out of seven food sources. Furthermore, an overview of additional possible measures to enhance biological control is given and known problems and limitations will be discussed. We conclude that it is possible to promote natural enemies in short rotation coppices through habitat manipulation. However, pest management becomes more and more complicated and requires high level of expertise of the land managers. |

Teratosphaeria nubilosa severely affects young plantations of Eucalyptus globulus and Eucalyptus maidenii in Uruguay. This work analyzes the effect of the damage caused by T. nubilosa on tree growth and survival of E. globulus and E. maidenii, based on data from a trial naturally infected by this pathogen. The effect of defoliation and proportion of adult foliage on tree growth and mortality was evaluated at 50 months of age. Defoliation in E. globulus was higher than in E. maidenii, reaching average values of 52.5 and 28.8 %, respectively, at 21 months of age. By contrast, E. globulus showed higher precocity of vegetative phase change than E. maidenii. Although the damage threshold for diameter growth was 40 % on E. globulus and 20 % on E. maidenii, the detrimental effect on growth was similar in both species, where the most defoliated trees suffered a reduction in diameter of 49.4 and 47.5 %, respectively, at 50 months of age. Mortality increased significantly when defoliation exceeded 30 % in E. globulus and 40 % in E. maidenii. The results showed that E. maidenii has lower defoliation, higher growth and lower mortality than E. globulus after epidemics of T. nubilosa. However, the lower defoliation and higher proportion of juvenile foliage showed by E. maidenii represent a greater source of inoculum, suggesting that a large-scale replacement of E. globulus by E. maidenii in areas where T. nubilosa is a problem could be risky from an epidemiological point of view. |
