Introduction
I was a post Doc at the University of Jyväskylä. Most of my research is about the interaction between plants, herbivores and their parasitoids. My latest research was focused on the produced VOCs of Plantago lanceolata and Veronica spicata when attacked by their specialised herbivores and the attraction of the parasitoids of these herbivores by these VOCs.

Article
Full-text available
This article describes the process the teacher students carried out and the results they achieved when they took part in JAMK’s Future Factory activities. At the School of Professional Teacher Education such a possibility is offered in the PEDA Lab environment in where students can participate in structured and supported pedagogical development pro...
Article
Full-text available
Even for parasitoids with a wide host range, not all host species are equally suitable, and host quality often depends on the plant the host feeds on. We compared oviposition choice and offspring performance of a generalist pupal parasitoid, Pteromalus apum (Retzius) (Hymenoptera: Pteromalidae), on two congeneric hosts reared on two plant species u...
Article
Full-text available
Sequestration of plant defensive chemicals by herbivorous insects is a way of defending themselves against their natural enemies. Such herbivores have repeatedly evolved bright colours to advertise their unpalatability to predators, i.e. they are aposematic. This often comes with a cost. In this study, we examined the costs and benefits of sequestr...
Article
Spatial variation in chemical defense of plants can be caused by genetic, biotic, and abiotic factors. For example, many plants exhibit a latitudinal cline in chemical defense, potentially due to latitudinal variation in abiotic environmental factors such as the light regime during the growing season. In the worldwide distributed Plantago lanceolat...
Article
Resistance and tolerance are different strategies of plants to deal with herbivore attack. Since resources are limited and resistance and tolerance serve similar functions for plants, trade-offs between these two strategies have often been postulated. In this study we investigated trade-offs between resistance and one aspect of tolerance, the abili...
Article
Full-text available
Defensive chemicals produced by plants can travel up the food chain by being sequestered by herbivores, and then in turn being sequestered by their parasitoids. Insect species with wide host ranges are predicted to perform poorly in the face of specific chemical defence. However, a species at a high trophic level is expected to have a wide host ran...
Article
Full-text available
Numerous herbivorous insect species sequester noxious chemicals from host plants that effectively defend against predators, and against parasitoids and pathogens. Sequestration of these chemicals may be expensive and involve a trade off with other fitness traits. Here, we tested this hypothesis. We reared Glanville fritillary butterfly (Melitaea ci...

Article
Full-text available
The ability to cope with plant defense chemicals differs between specialist and generalist species. In this study, we examined the effects of the concentration of the two main iridoid glycosides (IGs) in Plantago lanceolata, aucubin and catalpol, on the performance of a specialist and two generalist herbivores and their respective endoparasitoids....
Article
Full-text available
The coloration of species can have multiple functions, such as predator avoidance and sexual signalling, that directly affect fitness. As selection should favour traits that positively affect fitness, the genes underlying the trait should reach fixation, thereby preventing the evolution of polymorphisms. This is particularly true for aposematic spe...
Article
Full-text available
Aposematic herbivores are under selection pressure from their host plants and predators. Although many aposematic herbivores exploit plant toxins in their own secondary defense, dealing with these harmful compounds might underlay costs. We studied whether the allocation of energy to detoxification and/or sequestration of host plant defense chemical...
Article
Full-text available
The oviposition choice of an insect herbivore is based on a complex set of stimuli and responses. In this study, we examined the effect of plant secondary chemistry (the iridoid glycosides aucubin and catalpol) and aspects of size of the plant Plantago lanceolata, on the oviposition behavior of the specialist butterfly Melitaea cinxia. Iridoid glyc...
Article
Full-text available
We present a study of habitat use, oviposition plant choice, and food plant suitability for the checkerspot butterfly Melitaea athalia Rottemburg (Lepidoptera: Nymphalidae) in Åland, Finland. We found that in Åland, unlike in the mainland of Finland and many parts of its range, M. athalia flies mainly in open meadows. When offered an array of plant...
Thesis
Full-text available
Because plants cannot run away from their attackers, move to more favourable locations or hide, they have to be able to tolerate, adapt and/or defend themselves. Plants have evolved an enormous array of mechanical and chemical defences against herbivores. One can distinguish three types of defence strategies: direct defences that directly affect th...
Article
Host size is considered a reliable indicator of host quality and an important determinant of parasitoid fitness. Koinobiont parasitoids attack hosts that continue feeding and growing during parasitism. In contrast with hemolymph-feeding koinobionts, tissue-feeding koinobionts face not only a minimum host size for successful development but also a m...

In the solitary parasitoid wasp Venturia canescens both arrhenotokously (sexual) and thelytokously (parthenogenetical) reproducing individuals occur sympatrically. We found in the laboratory that thelytokous wasps are able to mate, receive and use sperm of arrhenotokous males. Using nuclear (amplified fragment length polymorphism, virus-like protei...

Question
I am looking for people to colaborate with to work on local adaptation of host plants (topic Plantago lanceolata). I already have plants from the Netherlands and Finland, but I would also like to get seeds from France, and ideally herbivores that feed on these plants (specialists and generalist). If you work on this system, or know somebody that does, please let me know.
