Sex-biased predation in dioecious willow - The long reach of plant genes Johan A. Stenberg Md. Faisal Kabir, Kim Karlsson Moritz & Johan A. Stenberg

Plants provide carnivores with: ResourcesInformation

Extended phenotype: All effects that genes have on their environment

Study system: dioecious willow Salix cinerea ♂♀ Phratora vulgatissima Anthocoris nemorum

Sex-biased insect densities in the field

Sex-biased predation in the field Male Female n = 22 plants Female Male

Sex-biased herbivore performance?

Sex-biased herbivore preference?

Sex-biased predator performance?

Sex-biased predator preference?

Summary + discussion 1.Female plants harbor higher densities of the herbivore and its omnivorous predator in the field. 2.The herbivore prefers female plants despite high predation pressure on females. 3.The omnivorous predators perform better on male plants. 4.The herbivore probably prefers female plants as the arena for interactions with the predator since female plants are suboptimal for the predator.

Tentative conclusions 1.The insects preference for female plants seems to be adaptive. 2.The extended phenotype of Salix cinerea structures the ecological interactions between herbivores and predators.

Work continues in PhD project 30 fields. 20 male, 20 female genotypes. Male, female and mixed fields. Interactions within fields. Effects on neighbouring strawberries. Kim Karlsson Moritz

Importance for short rotation coppice - Plantations are unisexual. - Choosing the ’right’ plant sex is an important part of IPM.
