The infection symptom of OrNV on the larvae Infected larvae by M. Utilisation of insect-specific Oryctes Nudivirus (OrNV) used the adults as vectors to spread the virus to other healthy beetles. Spraying the fungus solutions on the breeding locations was successful in killing up to 80% of the larvae. Metarhizium anisopliae was found to be a virulent entomopathogenic fungus against the rhinoceros beetle. The damaged palms exhibited wedged or v-shaped leaves due to boring activity of the rhinoceros beetle. Compared to the chipped trunks on the ground, the dead standing palm attracted substantially more beetles. The practice of underplanting, in which young seedlings were planted beneath poisoned standing old palms. Rotten chipped oil palm in the replanting areas provides excellent breeding sites for the beetle. Do Rhinoceros Beetles Fly Rhinoceros beetles CAN fly Keeping in mind that they can fly, but that they are pretty much harmless (unless their prickly legs deter you), rhinoceros beetles can be. Still, they are very strong and their legs are quite prickly. The introduction zero burning of old palms prior to the replanting. Rhinoceros beetles don’t sting or bite Also, they won’t stab you with their horn. The diameter of the head capsules was used to distinguish each instar. There are three larval instars, each of which takes 82 to 207 days to develop into pre-pupae. The females deposited about 70-100 yellowish-white eggs, which hatched into c-shape larvae after 8-12 days. The male could be differentiated from the female by having a longer horn. The adult rhinoceros beetle has a cephalic horn and black shiny body that is 35-50 mm long and 20-23 mm in width. The rhinoceros beetle’s entire life cycle spans between four and nine months from egg to adult, depending on environmental factors such as humidity, climatic conditions, and food availability. The rhinoceros beetle has been a major pest of oil palms since the 1990s, and it can be found in all of Malaysia’s states. The rhinoceros beetle, Oryctes rhinoceros, is a Southeast Asian native that was accidentally introduced to the South Pacific regions such as American Samoa, Fiji, Mayotte, Palau, Papua New Guinea, Reunion, Samoa, Tokelau, Tonga, Wallis, and Futuna along with import materials viz timber, habitat materials, and nursery commerce.
