Secondary Metabolites Released by The Burying Beetle Nicrophorus vespilloides: Chemical Analyses and Possible Ecological Functions

Burying beetles of the genus Nicrophorus localize small vertebrate carcasses by emitted volatiles. The carcass that serves as reproduction and breeding site is buried in the soil by the beetles. Biparental care for offspring includes both preservation of the carrion and its preparation as diet and nursery. Buried carcasses show no signs of microbial decay, and those experimentally treated with Nicrophorus secretions are known to grow fewer bacteria and fungi. In order to investigate the chemical composition of these secretions, we used GC-MS for analysis of methanolic extracts of anal and oral secretions released by adult N. vespilloides. Furthermore, we analyzed the headspace of adult N. vespilloides by SPME-GC-MS and searched for compounds with known antimicrobial activity. We identified 34 compounds in the headspace, and anal and oral secretions, 26 of which occurred consistently. We discuss the ecological relevance of these compounds with respect to both their antimicrobial activity and ecological relevance.

“…Other studies (K. Gallagher, unpublished) of Gumaga spp. reveal that these saclike glands are similar to the glands on the fifth abdominal sternites that are described and illustrated by Duffield et al (1977) and Nielsen (1980) for other species of Trichoptera. Histological sections of G. nigricula reveal that a pair of muscles is attached to the neck of each gland, and we presume that they regulate release of substances from the gland reservoir.…”

Field tests with chemical extracts of various body sections of adult caddisflies indicate that the female fifth abdominal sternite in the sericostomatids Gumaga nigricula (McL.) and Gumaga griseola (McL.) and the limnephilid Dicosmoecus gihipes (Hagen) contains a substance that attracts conspecific males. This sex pheromone is most likely produced by the paired exocrine glands located on the fifth sternite. Chemical extracts of female G. nigricula also attracted G. griseola males.
