“…Different results regarding B. bassiana infection with a lower average death rate for O. rhinoceros larvae ranging from 20-55% with a longer death time on day 6 after infection. The results of microscopic identification of dead larvae showed that there were B. bassiana hyphae and conidia which strengthened the evidence of successful B. bassiana infection [11].…”

“…This is because the toxin produced by B. bassiana plays a role in influencing the target host's movements related to locomotion activity and the larvae appear more passive. Entomopathogens release toxins that cause paralysis in the insect's body [11]. Paralysis causes loss of coordination, so that the insect's movements become erratic and gradually weaken, then stop altogether.…”

“…Infected O. rhinoceros larvae experienced a decrease in activity. Larvae that initially move normally will be passive and when the larvae die, the cuticles will be dull, pale and the body parts of the larvae will become smaller [11]. Apart from that, the larva's body will become stiff and hyphae will grow to fill the body after 7-12 days of larval death due to Beauveria bassiana infection.…”

The potential of Beauveria bassiana as a biological control agent for Oryctes rhinoceros is still rarely reported. The objective of the research was to analyse the behaviour and mortality of O. rhinoceros larva due to exposure to several of B. bassiana. The research method used the Completely Randomized Design and analysis with 5% Tukey’s test. The results showed that B. bassiana form different sites had the potential to be developed as an effective biological control product in controlling O. rhinoceros as a part of novelty to explore the biodiversity of native biological control in Indonesia. Larvae of O. rhinoceros that were exposed to and infected with B. bassiana experienced changes in movement activity and decreased appetite as well as differences in cuticle colour, the initially limp body will turn stiff while the cuticle colour will change and the next symptom will be white mycelium growth which was proven by the SEM. The B. bassiana from Jember 1 had the highest mortality rate of 37.5% at 30 days after application even though it had the lowest spore density. These results indicate something new and require further study regarding the toxin content of each B. bassiana from different sites.

The Rhinoceros beetle (Oryctes rhinoceros) is the main pest that causes severe impacts on palm oil plantations. The technology for controlling O. rhinoceros is more focused on utilizing the biological agent Metarhizium anisopliae, which is added to the compost called Metankos. The study aimed to obtain the best dose of local M. anisopliae biopesticide flour formulation on Metankos on mortality of O. rhinoceros larvae. The study was conducted experimentally using a completely randomized design consisting of eight treatments with four replications to obtain 32 experimental units. Each experimental unit consisted of 10 larvae of O. rhinoceros instar II. The treatments used several doses of M. anisopliae flour formulation with doses of 0, 30, 60, 90, 120, 150, 180, and 210 g/5 kg compost/bucket. The result showed that a 60 g/5 kg compost/bucket of the best compost mixed with a formulation of M. anisopliae flour induced a 52.5% mortality rate for O. rhinoceros larvae.

The goals of this study were to explore and identify entomopathogenic fungi, as well as determine the most effective application techniques to control S. frugiperda from exploration of infected Spodoptera frugiperda larvae in Purbalingga Regency. The research was carried out at the Plant Protection Laboratory, Faculty of Agriculture, Jenderal Soedirman University, from January to May 2022. Samples were collected by purposive random method. The study used a Complete Randomized Design, consisting of two factors, namely the type of entomopathogenic fungus and the application technique, with 9 combinations and 3 replications. Observed variables include mortality, feeding activity, growth, and reproduction of larvae. The results showed that (1) the results of exploration of entomopathogenic fungi were from the genus Metarhizium sp. and Penicillium sp. (2) single treatment of Metarhizium sp. is more effective than Penicillium sp. in killing S. frugiperda larvae. Fungi Metarhizium sp. and Penicillium sp. decreased feeding activity, length of three-instar larval period, and number of eggs, respectively 24.99 and 15.99%, 4.71 and 2.46%, 9.18 and 8.04% against controls. (3) single treatment of feed soaking method decreased mortality by 55.18% than other methods. Spraying the larval body decreased mortality by 44.84% compared to other methods. The method of application did not affect the feeding, growth and fecundity activity of larvae. (4) The combined treatment of Metarhizium sp., spraying the larval body, and soaking feed had a mortality percentage of 60%. Interaction treatment of the fungus Metarhizium sp. and the method of application lowered the feed power by 16%. The decrease in the period of three instar larvae to pupae and the largest number of eggs in the combination treatment of Metarhizium sp. and spraying of larval bodies was 6.34% and 11.20% respectively compared to controls.
