Chemotaxonomy of stored product pests by Attenuated Total Reflectance Fourier-Transform Infrared Spectroscopy (ATR-FTIR) and Identification of potential resistance markers in the insect cuticle
Project
Project code: JKI-ÖPV-08-1321
Contract period: 01.01.2016
- 31.12.2020
Purpose of research: Experimental development
Keywords: stored product protection, pest control, insect cuticular lipids
Insect cuticular lipids are chemically composed species-specific and may contain signal compounds, encoding i.e. sex or age. The aim of this cooperative studies between the group of plant analysis and stored product protection is the investigation of Attenuated Total Reflectance Fourier-Transform Infrared Spectroscopy (ATR-FTIR) as analytical tool for chemotaxonomic determination of different stored product pests. Furthermore, the possibility to distinguish between insecticide resistent and susceptable populations of the same species based on profiling of the insect cuticular lipids will be considered. This would provide an easy applicable and low cost analytical technique for taxonomic classification of pests and decision-making support for optimal pest control for stored product protection. Therefore, in preliminary studies three varietys of Sitophilus should be investigated concerning the chemotaxonomic differentiation of their cuticular lipids by ATR-FT-IR and GC-MS. Additionally, for Sitophilus oryzae, two populations differing in theis resistance / susceptabiliy to phosphine will be compared.
