2023 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.

topics (OpenAlex): Neurobiology and Insect Physiology Research; Insect behavior and control techniques; Insect Utilization and Effects
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.

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

topics (OpenAlex): Insect behavior and control techniques; Plant and animal studies; Forest Insect Ecology and Management
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)

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*

topics (OpenAlex): Forest Insect Ecology and Management; Insect and Pesticide Research; Insect behavior and control techniques
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.
