Genome-wide identification of genes involved in beetle odoriferous defensive stink gland function recognizes Laccase2 as the phenoloxidase responsible for toxic para-benzoquinone synthesis

Bibi Atika, Sabrina Lehmann, Elisa Buchberger, Musa D. Isah et autres

Exocrine glands have evolved several times independently in Coleoptera to produce defensive chemical compounds with repellent, antimicrobial, or toxic effects. Research on such glands had focused on morphological or chemical ecology methods. However, modern genetic approaches were missing to better understand this …

Synthetic biology approaches to generate temperature‐sensitive alleles for the Sterile Insect Technique

Ernst A. Wimmer, Hassan M. M. Ahmed

The Sterile Insect Technique (SIT) is an environmentally friendly, sustainable pest control approach, which uses large-scale releases of sterile insects to suppress or eradicate target populations through infertile matings. The efficiency of SIT is enhanced by male-only releases requiring genetic sexing strains …

Biotechnology-enhanced genetic controls of the global pest Drosophila suzukii

Ying Yan, Hassan M. M. Ahmed, Ernst A. Wimmer, Marc F. Schetelig

Spotted wing Drosophila (Drosophila suzukii Matsumura, or SWD), an insect pest of soft-skinned fruits native to East Asia, has rapidly spread worldwide in the past 15 years. Genetic controls such as sterile insect technique (SIT) have been considered for the environmentally friendly …

Divergent evolution of male-determining loci on proto-Y chromosomes of the housefly

Xuan Li, S.L. Visser, Jae Hak Son, Elzemiek Geuverink et autres

Abstract Houseflies provide a good experimental model to study the initial evolutionary stages of a primary sex-determining locus because they possess different recently evolved proto-Y chromosomes that contain male-determining loci (M) with the same male-determining gene, Mdmd. We investigate M-loci genomically and …

Anatomic and neurochemical analysis of the palpal olfactory system in the red flour beetle Tribolium castaneum, HERBST

Björn Trebels, Stefan Dippel, Janet Anders, Clara Ernst et autres

The paired antennal lobes were long considered the sole primary processing centers of the olfactory pathway in holometabolous insects receiving input from the olfactory sensory neurons of the antennae and mouthparts. In hemimetabolous insects, however, olfactory cues of the antennae and palps …

Competitive Sperm-Marked Beetles for Monitoring Approaches in Genetic Biocontrol and Studies in Reproductive Biology

Musa D. Isah, Bibi Atika, Stefan Dippel, Hassan M. M. Ahmed et autres

Sperm marking provides a key tool for reproductive biology studies, but it also represents a valuable monitoring tool for genetic pest control strategies such as the sterile insect technique. Sperm-marked lines can be generated by introducing transgenes that mediate the expression of …

Phenotypic screen and transcriptomics approach complement each other in functional genomics of defensive stink gland physiology

Sabrina Lehmann, Bibi Atika, Daniela Großmann, Christian Schmitt-Engel et autres

BACKGROUND: Functional genomics uses unbiased systematic genome-wide gene disruption or analyzes natural variations such as gene expression profiles of different tissues from multicellular organisms to link gene functions to particular phenotypes. Functional genomics approaches are of particular importance to identify large sets …
