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. |

Abstract:
Weeds host of root-knot nematodes (Meloidogyne spp.), parasites of important crop plants mainly in tropical and subtropical regions, enable them to maintain themselves or increase their abundance in soils. To evaluate the host status of 31 weed species that commonly compete with crops, we experimentally inoculated them with 5000 eggs and second-stage juveniles (J2) of Meloidogyne enterolobii. Sixty days after inoculation, we measured several parameters related to infestation ability, including gall index (GI), number of eggs/g root, and reproduction factor (RF). About 77.4% (n = 24) of the weed species we assessed were susceptible (RF ? 1) to M. enterolobii infestation: Acanthospermum australe, Amaranthus deflexus, Amaranthus hybridus, Amaranthus spinosus, Amaranthus viridis, Bidens pilosa, Bidens subalternans, Cardiospermum halicacabum, Commelina benghalensis, Euphorbia heterophylla, Galinsoga parviflora, Ipomoea grandifolia, Ipomoea nil, Ipomoea purpurea, Leonurus sibiricus, Nicandra physaloides, Polygonum hydropiperoides, Portulaca oleracea, Rhynchelytrum repens, Sida rhombifolia, Solanum americanum, Solanum sisymbriifolium, Solanum pseudocapsicum, and Talinum paniculatum. In contrast, seven species were resistant (RF < 1) to M. enterolobii infestation: Conyza bonariensis, Cyperys rotundus, Digitaria horizontalis, Digitaria insularis, Eleusine indica, Raphanus raphanistrum, and Senecio brasiliensis. Management strategies to control M. enterolobii should identify susceptible weeds in crop fields and control these potential alternative hosts of the parasitic nematode. MenosAbstract:
