Rhinoceros Beetle In Australia

[Raguel Charrette]

If they spread to Australia, garden palms would be at risk, along with the country's emerging date industry, coconuts, oil palms, and many other palms, both wild in the forests and ornamental," Dr. Etebari said.

UQ's Professor Michael Furlong said the research team investigated the beetle's population genetics and the incidence of the virus in specimens collected in Fiji, New Caledonia, Papua New Guinea (PNG), Samoa, Solomon Islands, Tonga, Vanuatu and the Philippines.

"We know the virus doesn't kill the beetles outright, but probably affects the number of eggs a female lays and changes beetle behavior, for example how far infected beetles can fly, so we need to explore these important aspects of the interaction too."

"The coconut rhinoceros beetle remains a serious threat to livelihoods across Pacific islands, where the coconut tree remains their 'tree of life," providing essential resources like food, copra, building materials and coastal protection for five million vulnerable people," he said.

Rhinoceros beetles are easy to maintain and care for, in fact, they need very little care at all. Because of this, the care time required and the cost of upkeep is virtually nil, yet they are very interesting and unique.

When the sun is out, they hide under logs or in vegetation to camouflage themselves from the few predators big enough to want to eat them. If rhinoceros beetles are disturbed, some can release very loud, hissing squeaks. The hissing squeaks are created by rubbing their abdomens against the ends of their wing covers.

An external pair of thick hard wings sit on top of another set of membranous wings, allowing the rhinoceros beetle to fly, although not very efficiently, owing to its large size. Their best protection from predators is their large size and stature. If Rhinoceros Beetles are disturbed, some can release very loud hissing sound.

Well done Arthur! It was great hanging out with you during your school excursion; you have so much knowledge to contribute! You definitely taught me a thing or too, thanks so much.

I hope the natural world always interests you ?

Came across this site. You are so lucky Arthur! I am 6yo and also very interested in beetles. We are going up to cairns at the end of september. Do you reckon we can find rhino beetles at that time? where should we look?

Wow, I never knew those grubs were Rhino beetle lavae!! Always find them in the garden, just ignorant to the grubs lineage. Now that I know what they belong to, i will be purposefully setting up a compost bed just for those beetles. I have always admired their size and power. Good on you Arthur for teaching this 47 year old Townsville bloke something new! Keep interested and stay safe my little nature legend!!

"Well this is a new one for me... So this morning call came through Jeremy's Reptile Relocations Townsville but as the young fellas laid up in bed with an injury I jumped on the tools to help out," James Bindoff, who runs the Townsville Snake Catcher service and Facebook page, said in a post.

These beetles measure up to 6 inches long and are found across Queensland in Australia. They make a loud hissing noise when disturbed, which they generate by rubbing part of their abdomen against the ends of their forewings, according to Land for Wildlife.

Males have a much larger horn than females, and will often gather on trees, knocking other males out of the way when they sense a female's pheromones. Many species of rhinoceros beetle are incredibly strong for their body weight, and are capable of lifting objects of between 30 and 100 times their own mass, according to the National Wildlife Federation. This strength and their large horns are used to fight other males for access to mating with females.

After mating, female common rhinoceros beetles will lay around 50 eggs in rotting wood and other organic matter, which will take around three weeks to hatch into large larvae, which feed on the detritus for around two years before transforming into their adult form. Their adult lives only last two to four months.

These beetles aren't the only rhinoceros beetle in Australia: there are nearly 200 species of the beetle across the country, including the three-horned rhinoceros beetle, Haploscapanes australicus, and the African Black Beetle, Heteronychus arator.

The Rhinoceros Beetle MI01 is the third product of Rokr's DIY Mechanic Organism 3D puzzle Series after the Storm Beetle MI03. Inspired by the real rhinoceros beetle in nature, our designers combined steampunk elements with it to create a highly mechanical aesthetic rhinoceros beetle model while retaining its details, such as the body shape, horn, legs and wings. The main body of the beetle is made of ABS polymer structure material with good impact resistance, the hard wings are covered with leather, and the limbs are made of soft PVC material to protect the model better.

As the overall control of the squad, the rhinoceros beetle plays a vital role in the entire team - its intelligent brain is able to coordinate tactics quickly and deliver mission instructions thanks to the core armored horn. In addition, its hydraulic mechanical forelimbs, orange peel leather armor, and membranous wing heat abstractor also help it to play better on the battlefield as well as protect its body from enemy attacks. What's more, this rhinoceros beetle model also has eight sets of brass piston connecting rods built in to show the engine cylinder running at high speed. Also, the LED engine indicator light illuminate the internal mechanical structure of the engine, enhancing the power perception and also making the whole model cooler.

After connecting the custom base, the model can be activated by gently touching the activation point at the top of the base: the motor speed up to 1200 rpm, and the membranous wings can vibrate 618 times per minute, simulating the movement of real rhinoceros beetles.

We are committed to providing innovative, creative and environmental-friendly DIY products for people worldwide with the brand purpose of "focus on originality, born different." Our mission is to tap into happiness and spread positive, healthy, global, and trendy lifestyles for people of all ages.

Oryctes rhinoceros nudivirus (OrNV) has been an effective biocontrol agent against the insect pest Oryctes rhinoceros (Coleoptera: Scarabaeidae) for decades, but there is evidence that resistance could be evolving in some host populations. We detected OrNV infection in O. rhinoceros from Solomon Islands and used Oxford Nanopore Technologies (ONT) long-read sequencing to determine the full length of the virus genomic sequence isolated from an individual belonging to a mitochondrial lineage (CRB-G) that was previously reported as resistant to OrNV. The complete circular genome of the virus consisted of 125,917 nucleotides, 1.698 bp shorter than the originally-described full genome sequence of Ma07 strain from Malaysia. We found 130 out of 139 previously annotated ORFs (seven contained interrupted/non-coding sequences, two were identified as duplicated versions of the existing genes), as well as a putatively inverted regions containing four genes. These results demonstrate the usefulness of a long-read sequencing technology for resolving potential structural variations when describing new virus isolates. While the Solomon Islands isolate exhibited 99.41 % nucleotide sequence identity with the originally described strain, we found several genes, including a core gene (vlf-1), that contained multiple amino acid insertions and/or deletions as putative polymorphisms of large effect. Our complete annotated genome sequence of a newly found isolate in Solomon Islands provides a valuable resource to help elucidate the mechanisms that compromise the efficacy of OrNV as a biocontrol agent against the coconut rhinoceros beetle.

There are more than 30,000 species of scarab beetles worldwide. Australia is home to at least 2300 of these species, including iridescent Christmas beetles (Anoplognathus), spectacularly horned rhinoceros beetles (Dynastinae), and the beautifully patterned flower chafers (Cetoniinae).

For example, when Europeans began planting sugar cane (a type of grass) and converting native grasslands to pastures, many native Australian scarab species found an abundant new food source and were subsequently classified as pests.

Plants are surprisingly resilient, and most can handle losing a small number of their roots to beetle larvae. Even while damaging plants, curl grubs may be helping keep soil healthy by providing aeration and nutrient mixing.

Unfortunately, identifying scarab larvae species is challenging. Many of the features we use to tell groups apart are difficult to see without magnification. While there are identification guides for scarabs larvae found in pastures, there are currently no such identification resources for the scarabs found in household gardens.

Lawns are particularly susceptible to attack by the larvae of non-native scarabs. Consider replacing lawns with native ground covers. This increases biodiversity and lowers the chances of damage from non-native scarab larvae.

Interpretive Summary: Scientists at the Center for Medical, Agricultural, and Veterinary Entomology, the University of Guam, and BSES Limited of Australia, collected and analyzed sounds produced by the coconut rhinoceros beetle in palm trees in Guam. The adults of this beetle cause great economic damage and can kill coconut palms. They are difficult to find visually because they attack the tops of the trees. This study demonstrated, however, that their movement and feeding and scraping sounds can be detected over long distances in a tree, and acoustic sensors could be used to detect hidden infestations. The sounds can be helpful to discriminate the beetle sounds from background noise. Other related beetles in Australia produce similar sounds. These results may be helpful in development of new methods to identify infested trees in quarantined areas. The sounds also are of interest in studies of insect communication.
