![]() “Some of the islands of Palau have been completely eluted of coconuts in the main islands of Babeldoab and Korror they’ve lost 50 percent,” said Dr. The UOG entomologist says this is based on the experiences of the islands of Palau who probably got the rhino beetle during World War II. “We can expect to lose 50 to 75 percent of our coconuts that’s just the way it’s going to be,” said Dr. Ross Miller painted a bleak picture of Guam’s invasive species problem saying that we can expect the coconut rhinoceros beetle to wipe out more than half of our coconut trees and we can expect more invasive species to come.

In Palau, following WWII, especially on the ialnds of Angaur and Peleliu – there was a lot of rotting wood from trees felled during the fighting. A member from Palau wrote the the potential impact of the coconut rhinoceros beetle depends on tne availability of its breeding sites. There is also an article about the release of Metarhizium here: /0/from-discovery-to-eradication-the-coconut-rhinoceros-beetle-on-guam/ A decline in the damage done is reported, supported by a YouTube video: The ‘artificial breeding sites’ were established at the perimeter of replanting, 250 m from each other. anisopliae was applied to artificial breeding sites with pheromone traps and significantly reduced the population of Oryctes in oil palm replanting areas. See, Reports from India and Malaysia said that Metarhizium anisopliae had performed well in controlling larvae at breeding sites. The beetle is now all over northern and central Guam. Apparently, the virus has not worked well on Guam. ![]() An article online by the University of Gua details grants given by USDA APHIS and USDA Forest Service to bring the beetle under control. In the Philippines, the beetle larvae are used as feed for chickens, ducks and pigs, and in Papua New Guinea they are important delicacies in the lowlands, and a source of food for free-ranging pigs. Grubs have also been found in rotting breadfruit/banana used for earth ovens in Samoa, and in compost in Palau. Any site with rotting vegetation is a potential breeding site for this beetle. Members also thought that there were less ground sites on Guam where the beetle can breed, so that alternative sites have been sought, i.e. Rats previously made their nests in the crowns of palms, and ate the grubs of rhinoceros beetles. The reason for this is thought to be because the brown tree snake has killed most of the rats on Guam. Large numbers of beetles are reported to be breeding in the crown of palms, an activity not reported before. ![]() SPC is working with others on baculovirus strains. Advice on a suitable IPM strategy, involving pheromones, baculovirus and Metarhizium anisopliae, can be obtained from the Secretariat of the Pacific Community, Fiji. The rhinoceros beetle is the major pest of oil palm in India migrating from coconut and palmyrah. This scarab beetle is a serious pest of coconuts, other palms and cycads, and it has never been reported previously on Guam. An infestation of the coconut rhinoceros beetle, Oryctes rhinoceros, has been found at Tumon Bay, Guam.
