The impact of deffensive host-plant traits on community structure of herbivorous insects on willows
VOLF, Martin
This study examines the role of deffensive host-plant traits in structuring the community of leaf-chewing insects living on willows. Host-plant phylogeny was reconstructed and leaf morphology and content of three different groups of secondary metabolites were measured. Relationships between defensive leaf traits were examined and their influence on insect community structure was analyzed.
Community structure of leaf-chewing insect on willows
VOLF, Martin
The communities of leaf-chewing insect on willows were studied. The effect of host-plant phylogeny, leaf morphology and secondary metabolites on community structure was examined.
The effect of ants predation risk for herbivorous insect
DRAG, Lukáš
This thesis is the first step to evaluate the relationship between ant activity (predation risk) and the leaf damage caused by herbivorous insects. Tuna baits which were used in 1, 2 and 3 hours intervals to attract different species of invertebrates. The degree of herbivory was measured as the proportion of leaves that had been chewed or mined by herbivores. The most abundant and frequent potential predators were ants. All ant species were determined and patterns of their activity analysed.
