Abstract :
[en] Halyomorpha halys St˚al (Hemiptera, Pentatomidae) is an invasive stink bug coming from
Eastern Asia. Besides causing important yields losses in orchards, crop and vegetable fields,
it overwinters inside houses as agglomerates of dozens. In Europe, this Brown Marmorated
Stink Bug (BMSB) was accidentally introduced in Switzerland in 2007 and has been later
observed in surrounding countries (France, Italy, Germany). Based on the current US situation,
we can reasonably fear that BMSB will have colonized most of Europe countries in less
than a decade. If we already discern a few fungus strains that are efficient against BMSB,
very little is known about their actual impact on the insect itself. So we investigated the in-
fluence of a fungal infection on insect development parameters and behaviour. Olfactometry
was settled to investigate the dispersion and aggregation trends, while electropenetography
was used to assess the feeding behaviour. Our results will be discussed to present changes
according to healthy/fungus-infected status, in relation to potential biological control for
that pest.
