ABSTRACT.
We tested two modifications into single-step genomic BLUP (ssGBLUP) that allow it to work with a large amount of genotyped animals. The first method is based on genomic recursions (APY) to construct the inverse of the genomic relationship matrix without directly inverting it; all available genotyped animals are included in ssGBLUP with APY, but they are split into base and non-base, and the method returns direct predictions. The second method is an interim genomic evaluation (IP) for young genotyped animals; only a reference set of animals are used in ssGBLUP with IP, and the method returns indirect predictions for young genotyped animals. A dataset from American Angus with records for growth traits was used. Over 8 million animals were in the pedigree, of which 51,883 were genotyped. The ssGBLUP with APY was as accurate as regular ssGBLUP when the number of genotyped base animals was at least 10,000; this method was also faster and required less memory. The ssGBLUP with IP mimicking the previous official evaluation returned the same accuracy of GEBV for young animals as the regular ssGBLUP. While the first method enables complete genomic evaluations for huge genotyped populations, the second allows for quick genomic predictions on young animals without including their information into a new run of evaluation. |

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. |
