![]() The general anatomy of a beetle is quite uniform and typical of insects, although there are several examples of novelty, such as adaptations in water beetles which trap air bubbles under the elytra for use while diving. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops.īeetles typically have a particularly hard exoskeleton including the elytra, though some such as the rove beetles have very short elytra while blister beetles have softer elytra. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal species new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. “ Hawaii Grown” is funded in part by grants from the Stupski Foundation, Ulupono Fund at the Hawaii Community Foundation and the Frost Family Foundation.Clockwise from top left: female golden stag beetle ( Lamprima aurata), rhinoceros beetle ( Megasoma sp.), long nose weevil ( Rhinotia hemistictus), cowboy beetle ( Chondropyga dorsalis), and a species of Amblytelusīeetles are insects that form the order Coleoptera ( / k oʊ l iː ˈ ɒ p t ər ə/), in the superorder Endopterygota. “The areas where we have the highest population of the beetle essentially aligns with where we haven’t been able to engage the community,” he said. The level of awareness and consciousness within the community – including knowledge of how to avoid creating nesting sites and ensuring swift reporting of cases – was a model for the rest of Oahu to follow, Oishi said The most successful example of control, often cited by invasive species specialists, is how the military community responded after CRB was first discovered at Joint Base Pearl Harbor-Hickam. In the meantime, Oishi underscored the importance of community vigilance, including being careful with compost and reporting sightings of the critters. Oishi has estimated the price tag for much-needed infrastructure and research is $5 million. (David Croxford/Civil Beat/2023)īut lawmakers are now considering House Bill 1149, which would provide a hike in core funding for the program, along with more than 10 positions dedicated to controlling the insects. Traps have been set all over Oahu by the University of Hawaii and the Department of Agriculture. The diminutive trees could be a way to easier manage the persistent threat of the coconut rhinoceros beetle, but also raise the question of whether Hawaii is willing to invest in actually eradicating the invader. But having a low stature of tree, where you can get to the crown, it’s much easier than having a tall tree where you can’t see what’s going on,” Shepard said. ![]() That is unless something like the beetle comes along with the potential to decimate his crop. ![]() “They’re pretty much pest resistant and the coconuts can turn brown, fall off and sit there for months and then you put in mulch and let it sprout,” Shepard said in an interview. They require far less work than their taller counterparts and demand for them is increasing. He sells them by the pallet - 700 sprouted nuts were sent to Mahi Pono on Maui. When mature, each of his 350 trees can produce 250 nuts per year, which Shepard sprouts and sells around the island chain. One such farmer is Griffin Shepard, who runs Aloha Organics dwarf coconut tree farm on Kauai’s northwest coast. (David Croxford/Civil Beat/2023) Think Small And Prosperįarmers across the islands are keeping a close watch on Oahu’s beetle problem and potential solutions. Aloha Organics Dwarf Coconut Tree Farm has three varieties of low-bearing coconut trees, which it sells its sprouted seeds from.
