Removal of heavy oil using rhinoceros beetle, Oryctes rhinoceros

Journal of Environmental Management, 2019
The remnant of heavy oil, often expressed as total petroleum hydrocarbons (TPHs), in soil and/or sludge is commonly encountered by and often ruins the habitat of some indigenous insects. Recent studies indicate that some of the insects could stand the impact and some not just survived but might serve as an oil degrader.

Efficacy of botanical formulations against coconut rhinoceros beetle oryctes rhinoceros

Indian Journal of Entomology, 2022
Field efficacy of botanical cakes and insecticides when evaluated in coconut against the rhinoceros beetle Oryctes rhiniceros L., revealed that leaf damage reduced to 9.5% with botanical cake and paste. Palms treated with chlorantraniliprole 0.4% GR (10.5%) and neem cake admixed with sand (11.5%) were also effective compared to control (40.0%) at 30 ...

Character Displacement in Giant Rhinoceros Beetles

The American Naturalist, 2002
I quantitatively analyzed male morphology of two closely related rhinoceros beetles species (Chalcosoma caucasus F. and Chalcosoma atlas L.) in 12 allopatric and seven sympatric locations throughout Southeast Asia. The qualitative features and the magnitude of intraspecific variation of each species were unaltered between allopatric and sympatric ...

A mathematical model of invasion and control of coconut rhinoceros beetle Oryctes rhinoceros (L.) in Guam

Journal of Theoretical Biology, 2023
The coconut rhinoceros beetle (CRB), is one of the most damaging pests to coconut palms causing severe economic harm. Its expansion from Asia to the Pacific in the early 20th century has been stopped by virus control. However, a new haplotype CRB-Guam has recently escaped this control and invaded Guam, other Pacific islands, and has even established ...

Variation in the allometry of exaggerated rhinoceros beetle horns [PDF]

Animal Behaviour, 2015
Exaggerated horns are a characteristic feature of many male rhinoceros beetles. We surveyed and compared the scaling relationships of these sexually selected weapons for 31 Dynastinae species with different degrees of horn exaggeration. We found that nearly all rhinoceros beetle species were male dimorphic, that the allometric slope of major males was ...

Inexpensive Load Carrying by Rhinoceros Beetles

Journal of Experimental Biology, 1996
ABSTRACT These experiments determined the magnitude of loads that rhinoceros beetles (Scarabaeidae) can carry and also the metabolic energy required for carrying loads. I hypothesized that, like many other animals, these beetles would have metabolic rates in direct proportion to the total load (body mass plus added mass).
