The regulation of dsx in exaggerated beetle horn development has been studied in two beetle genera, dung beetles (Onthophagus) and rhinoceros beetles (Trypoxylus) [ 10, 11].
The short-term effect of windthrow gap size and isolation for saproxylic beetle abundance, species richness and assemblage composition was studied in managed oak-hornbeam forest in France.
The developmental interaction of dsx regulation and nutrition was studied in greater detail in the stag beetle (Cyclommatus metallifer) [ 75].
The effect of organic farming compared to conventional mixed and cereal farming on arable weeds and carabid beetles in boreal landscapes was studied by comparing the distribution of ecological traits, diversity partitions, species richness and abundance.
Michael Smith, an entomologist with the Agriculture Department, has been studying the beetle in China.
Dr. Smith has been studying the beetle's natural predators in China, parasitic wasps, other beetles and even fungi, as well as a beetle in the United States, for use as bio-controls.
SCIENTIST: I'm studying the mating habits of dung beetles.
Beetles were collected in August 2007 on lima beans at the same study site, which was selected for assessing herbivory and parallel quantification of accumulated cyanide in leaves.
In our experiments, virgin beetles were kept in same-sex groups, while virgin beetles were kept in isolation in the study by Fox et al. (2006).
The association of yeasts with beetle larvae has been extensively studied in a variety of cerambycids [ 7, 45, 46] and the importance of fungal enzymes to plant cell wall degradation in several cerambycid species has been demonstrated [ 47].
