Research

Insecticide Resistance

We investigate the mechanisms by which insects develop resistance to insecticides. Our approaches include classical bioassays and biotechnology-based approaches for the identification and validation of resistance mechanisms. The latter include recombinant enzyme-based techniques, in vivo functional approaches (ectopically expressed genes, CRISPR/Cas9 etc), immunolocalisation, electron microscopy (TEM, SEM) etc. Several insecticide resistance mechanisms in mosquitoes and agricultural pests were functionally elucidated recently (Figure 1, 2 and 3).

Insecticide resistant Anopheles gambiae walking apathetic on impregnated bednets


Figure 1. Insecticide resistant Anopheles gambiae "walking apathetic" on impregnated bednets. Modification of epicuticular hydrocarbons and remodeling of leg cuticles, as well as the overexpression of leg-enriched sensory appendage proteins (SAP2) confers pyrethroid resistance, by sequestering and substantially delaying insecticide uptake, giving time to detoxification mechanisms to detoxify them, thus producing striking insecticide resistance phenotypes.

Biotechnology based approaches for novel insecticides targets

Holistic biotechnology based approaches using state-of the-art technologies (transcriptomics, proteomics, functional and cell based assays – Pharma models) are applied to enable the identification of potential molecular targets in insect pests and mosquitoes, as well as elucidate the insecticide pharmacokinetics (cross midgut epithelium etc – Denecke et al IBMB 103, 22-35).
