![]() Many biotic and abiotic constrains limit global palm yield, resulting in a 30% loss (Sujithra et al. India is the world's leading producer of coconuts. Every component of the palm has a purpose, and the possibilities are endless. rhinoceros, and its field efficacy should be tested further to include the EPNs in the integrated pest management program in coconut.Ĭoconut is a traditional Indian crop that is valued as both a horticultural crop and an oilseed commodity. Present study found the effective native strain against O. Conclusionīased on the virulence, reproductive capacity, searching ability and LC 50 values, it is suggested that strain Sc1 have great potential as a biocontrol agent for the Oryctes management in coconut palms under humid tropical ecosystem. With different concentration of EPN tested, the production of infective juveniles (IJs) inside the cadavers for Sc1, Sa1 and Hi1 varied between 3223–10,365 4722–96,5–85,453 larvae −1, respectively. At 72 h of incubation, the LC 50 values of Sc1, Sa1 and Hi1 strains were 1078, 16 IJs larva −1, respectively. abbasi (92%) at 10 days post treatment, whereas H. The highest larval mortality was observed with S. Oryctes rhinoceros larval susceptibility to EPN significantly varied with the treatment dose and period of exposure. carpocapsae (CPCRI-Sc1), virulence and reproductive capacity were evaluated against second instar larvae of O. Heterorhabditis indica (CPCRI-Hi1), Steinernema abbasi (CPCRI-Sa1), and S. ![]() Hence, indigenous entomopathogenic nematode (EPN) strains, viz. However, indiscriminate use of chemical insecticides has created a lot of environmental and regulatory issues, thus warranting an ecologically safe and environmental friendly alternative option. the larval stage, which is cryptic in nature and spends nearly 90–160 days in the breeding site, is amenable to any control measures so as to reduce the population of actual damaging adult stage. rhinoceros grubs and adults have different feeding habits as the adults feed on plant tissues, whereas the grubs primarily feed on rotting organic matter. The adult beetle attacks the unopened leaves and inflorescences, resulting in a yield loss of more than 10%. Many biotic and abiotic constrains limit global palm yield and among the biotic factors, the coconut rhinoceros beetle, Oryctes rhinoceros (L.) (Coleoptera: Scarabaeidae) is the major problem in India. More recently aĬhemical attractant, ethyl-4-methyloctanoate, has been used in traps to attract and kill the beetles.India is the world's leading producer of coconuts. In many countries, the fungus Metarhizium anisopliae or the Oryctes virus are used to control the rhinoceros beetle. A hooked wire can be used to extract and destroy rhinoceros.It takes longer for rhinoceros beetle larvae to develop than it takes to make compost, so properly maintained compost should not serve as a source of rhinoceros When turningĬompost piles or applying compost to plants, destroy any rhinoceros beetles found. Compost piles should be maintained properly. ![]() Piles of dead leaves or grass can be composted, used for mulch,īurned, or spread on the ground in a thin layer.Ground covers can be planted or allowed to grow over logs or Rhinoceros beetles do not usually lay eggs in potential breeding sites that are obscured by growing vegetation.Dead, standing coconuts should be felled, chopped, dried, and.Cut stumps as close to the soil surface as possible.Chop and burn decaying logs or break them up and destroy any. ![]() "Rhinoceros beetles can be controlled by eliminating the places where they breed and by manually destroying adults So, make sure you create the worst conditions for this insect so they dont keep breeding and cause more damage. As with any pest insect we must think about the conditions now and what the conditions will be in the future. The promotion of natural enemies is a very good approach that reduces the incidence, is cost effective and does not harm your health like pesticides can. Let us assume this is Rhinoceros beetle damage. But since these are very young plants then maybe such holes do not appear. It is not clear to me this is indeed Rhinocerous beetle damage. ![]()
