The biology of many arthropods can only be understood when their associated microbiome is considered. The nutritional requirements of the bulb mite Rhizoglyphus robini Claparede (Acari: Astigmata: Acaridae) in the laboratory have been shown to be very easily satisfied, and in the field the mites prefer fungus-infected over uninfected plants. To test whether symbiotic bacteria facilitate the...

Arthropod symbioses : a neglected parameter in pest- and disease-control programmes

Zindel, Renate ; Gottlieb, Yuval ; Aebi, Alexandre

In: Journal of Applied Ecology, 2011, vol. 48, no. 4, p. 864–872

1. Arthropods are important players in biological control as pests, control agents and transmitters of invertebrate diseases. Arthropods are frequently infected with one or several micro-organisms, serving as micro-ecosystems in which multiple interactions can take place. These micro-organisms include disease agents and symbiotic micro-organisms. The latter are usually vertically...

Detecting arthropod intraguild predation in the field

Aebi, Alexandre ; Brown, Peter M. J ; De Clercq, Patrick ; Hautier, Louis ; Howe, Andy ; Ingels, Brecht ; Ravn, Hans-Peter ; Sloggett, John J ; Zindel, Renate ; Thomas, Alison

The process of biological control carries a distinct risk that an alien biological control agent (BCA) will become established as an invasive alien species with an associated threat to the local ecosystem biodiversity. It is imperative that a wide-ranging environmental risk assessment (ERA) is performed before the release of any BCA. This should include considering various potential but difficult...

Predation of native coccinellids by the invasive alien Harmonia axyridis (Coleoptera: Coccinellidae): detection in Britain by PCR-based gut analysis

Thomas, Alison P ; Trotman, Jamie ; Wheatley, Angela ; Aebi, Alexandre ; Zindel, Renate ; Brown, Peter M.J

In: Insect conservation and diversity, 2013, vol. 6, no. 1, p. 20-27

1. The harlequin ladybird, Harmonia axyridis, is an invasive alien species that arrived in Britain in 2003 and has spread across most of the country. 2. This spread has been accompanied by a decline in some native coccinellid species, in particular, the two spot ladybird Adalia bipunctata and the ten spot ladybird Adalia decempunctata. One reason for this decline...

Mites and endosymbionts : towards improved biological control

Zindel, Renate ; Turlings, Ted (Dir.) ; Aebi, Alexandre (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2012.

Gliederfüsser (Arthropoden) beherbergen sehr diverse Bakteriengesellschaften in ihrem Innern. Sie können durch ihre Wirte grosse Auswirkungen auf die biologische Schädlingsbekämpfung haben. Vor allem dann nämlich, wenn sie ihren Wirt auf eine Weise beeinflussen, dass dieser entweder in seiner Funktion als Nützling beeinträchtigt wird oder aber, wenn sie einem Schädling zur erhöhten...
