This is the case with the wood tiger moth (Arctia plantaginis), a generalist herbivore that uses multiple defensive compounds to deter predators. They can sequester defensive compounds, such as pyrrolizidine alkaloids (PAs), from their diet. According to resource allocation theory, resources invested in handling PAs cannot also be invested in other processes, such as growth. The costs and benefits of consuming toxins can also differ for specialists and generalists. Here, I manipulated the amount of plant material containing PAs in the diet and tested whether these compounds cause life history costs in 1) larval growth and development 2) strength of larval encapsulation response 3) larval and adult aposematic colouration 4) the release of adult defence fluids and 5) adult reproductive output with a full-sibling rearing design. I also studied possible genetic differences by using three genotype lineages. PA-diet larvae showed possible trade-offs by developing faster and having larger warning signals but lower pupal weight and lower melanization levels. PA-diet lowered encapsulation rate and reproductive output in females but increased encapsulation rate in males. PA-diet did not affect adult colouration or the release or quantity of defensive compounds: instead, these differed between genotypes. These results increase our knowledge about the capability of a generalist species to handle PA compounds.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2022-06-22T09:04:06Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2022-06-22T09:04:06Z (GMT).
