Monitoring the European pine sawfly with pheromone traps in maturing Scots pine stands (2006)

Lyytikainen-Saarenmaa, P, Varama, M, Anderbrant, O, Kukkola, M, Kokkonen, AM, Hedenström, E, ...

1 During 1989-93, field studies were conducted in Finland to develop a method based on pheromone traps to monitor and forecast population levels of the European pine sawfly (Neodiprion sertifer...

Sex pheromone of the pine sawfly, Gilpinia pallida: Chemical identification, synthesis, and biological activity (2006)

Hedenström, E, Edlund, H, Wassgren, AB, Bergström, G, Anderbrant, O, Östrand, F, ...

We present the identification of the sex pheromone in the pine sawfly, Gilpinia pallida, including analysis of the female pheromone content, male antennal response and attraction in the field, and...

Choosy egg parasitoids: specificity of oviposition-induced pine volatiles exploited by an egg parasitoid of pine sawflies (2005)

Mumm, R., Tiemann, T., Varama, M., Hilker, M.

Generalist parasitoids are well-known to be able to cope with the high genotypic and phenotypic plasticity of plant volatiles by learning odours during their host encounters. In contrast, specialised...

Insect egg deposition induces defence responses in Pinus sylvestris: characterisation of the elicitor (2005)

Hilker, M., Stein, C., Schroder, R.R.G., Varama, M., Mumm, R.

Egg deposition by the phytophagous sawfly Diprion pini L. (Hymenoptera, Diprionidae) is known to induce locally and systemically the emission of volatiles in Scots pine (Pinus sylvestris L.) that...

Predicting pine sawfly population densities and subsequent defoliation with pheromone traps (2001)

Lyytikäinen-Saarenmaa, P, Varama, M, Anderbrant, O, Kukkola, M, Hedenström, E, Högberg, HE

Field in Finland to develop a monitoring and prediction trials were conducted from 1989 to 1993 method using pheromone traps for European pine sawfly (Neadiprion sertifer Geoffr.) population...
