Hanseniaspora uvarum Attracts Drosophila suzukii (Diptera: Drosophilidae) With High Specificity

Journal of Economic Entomology, 115(4), 999–1007.

By: I. Kleman*, G. Rehermann *, C. Kwadha* , P. Witzgall * & P. Becher *

Ed(s): F. Zalom

TL;DR: The findings suggest that synthetic yeast headspace formulations might advance the development of more selective monitoring traps with reduced by-catch, and represent a suitable substrate for the development of lures that are more specific than vinegar and wine. (via Semantic Scholar)

2022 journal article

Heterologous expression and functional characterization of Drosophila suzukii OR69a transcript variants unveiled response to kairomones and to a candidate pheromone

Journal of Pest Science, 96(3), 1149–1171.

By: A. Cattaneo *, P. Witzgall *, C. Kwadha* , P. Becher * & W. Walker *

TL;DR: Following heterologous expression of single olfactory receptors (ORs) in ab3A olfactory sensory neurons of D. suzukii, in situ hybridization analysis on D. suzukii antennae suggests unique expression of OR69a-subunits in specific neurons, and points toward co-expression within the same neurons.

2022 journal article

Pathogenic fungus uses volatiles to entice male flies into fatal matings with infected female cadavers

The ISME Journal.

By: A. Naundrup*, B. Bohman *, C. Kwadha* , A. Jensen *, P. Becher * & H. Licht *

TL;DR: It is shown that the host-specific and behaviourally manipulating pathogenic fungus, Entomophthora muscae, generates a chemical blend of volatile sesquiterpenes and alters the profile of natural host cuticular hydrocarbons in infected female housefly (Musca domestica) cadavers, underlie the evolution of an extended phenotypic trait.

2022 journal article

The human odorant receptor OR10A6 is tuned to the pheromone of the commensal fruit fly Drosophila melanogaster

IScience, 25(11), 105269.

By: T. Frey *, C. Kwadha* , F. Haag *, J. Pelletier *, E. Wallin*, E. Holgersson*, E. Hedenström *, B. Bohman * ...

TL;DR: Screening ORs for key ligands leads to the discovery of messenger chemicals that enable chemical communication among and betwen vertebrate and invertebrate animals. (via Semantic Scholar)

2021 journal article

Detection of the spotted wing drosophila, Drosophila suzukii, in continental sub-Saharan Africa

Journal of Pest Science, 1.

By: C. Kwadha* , L. Okwaro *, I. Kleman*, G. Rehermann *, S. Revadi *, S. Ndlela *, F. Khamis *, P. Nderitu* ...

TL;DR: This is the first study to provide empirical evidence of D. suzukii in continental sub-Saharan Africa, confirming that the pest is expanding its geographic range intercontinentally. (via Semantic Scholar)

Decanal as a major component of larval aggregation pheromone of the greater wax moth, Galleria mellonella

Journal of Applied Entomology.

By: C. Kwadha* , J. Mutunga*, J. Irungu*, G. Ongamo *, P. Ndegwa *, S. Raina*, A. Fombong*

TL;DR: The involvement of volatile organic compounds in the aggregation behaviour of mature wax moth larvae and thereby offer prospects for the development of an odour‐baited in‐hive trapping management tool for wax moth larva. (via Semantic Scholar)

Insects.

By: C. Kwadha* , G. Ong’amo *, P. Ndegwa *, S. Raina* & A. Fombong*

TL;DR: An overview of the current knowledge on the biology, distribution, economic damage, and management options of the greater wax moth is provided and prospects that need consideration are provided for better understanding and management of the pest. (via Semantic Scholar)
