Abstract in another language

The present study provides the first insights into the chemical defensive system of the erotylid beetle, Tritoma bipustulata, and furthermore reports the previously hardly known ability of abdominal reflex bleeding in this coleopteran family. The defensive chemistry of the secretion of pronotal glands, abdominal reflex blood as well as of the haemolymph were analysed by GC-MS. The different secretions were dominated by aromatic compounds; in addition, we detected alkenes, ketones, organic acids as well as a single sesquiterpene. The majority of these detected compounds had strong antimicrobial properties in microbiological assays with entomopathogenic micro-organisms. In feeding bioassays with ants, only benzyl alcohol, benzothiazole, indole and 3-methylindole, detected in the abdominal reflex blood, were significantly deterrent.
