“…These four common beetles were found despite the eight years sampling gap indicated an intact habitat in Pelangai Forest Reserved. The Scarabaeidae was simply found as they withstand various types of habitat including grasslands, farms, and forests because they fed on carrion, fungi, insects, or plants from plantations (Manjeri et al 2013). Cerambycidae, Chrysomelidae, and Carabidae were still found in 2020 due to undisturbed forest area despite the potential of the area to undergo logging activity.…”

Abstract. Abdullah NH, Azmir IA. 2021. A pictorial key for the identification of beetle (Order: Coleoptera) and diversity study in selected area within Pelangai Forest Reserve, Negeri Sembilan, Malaysia. Biodiversitas 22: 947-955. Beetles or Coleoptera were largely distributed in Asia, especially in Malaysia. The beetle was important in the ecosystem as a decomposer, pollinator, and bio-indicator of the habitat. However, the beetle could also be a potential pest to crops or plants that cause damage to many plantations. This study aimed to establish a key pictorial for beetle identification based on selected characteristics and to determine the beetle diversity, evenness, and genus similarity in Pelangai Preserved Forest, Negeri Sembilan at three different sites i.e., forest, open area, and the sub forested area. This study was carried out between February and March 2020. The Shannon Evenness Index (E) calculated species evenness and the Simpson’s Index (D) assessed the diversity of beetles in this research. The results obtained were 67 individuals of beetles comprised of 7 families and 13 genera. The most found beetle was genus Apogonia sp. (16.4%), followed by genus Epilachna sp. (14.9%), and genus Adoretus sp. A (14.9%) while the least found beetle was genus Blabephorus sp. (1.5%). Site C or sub forested area had the highest species similarity (E= 0.913), followed by Site B or open area (E= 0.912) and Site A or forest area with the lowest species similarity (E= 0.908). This showed that the species in the sub forested area were evenly distributed compared to the forest and open area. As for diversity index, sub forest had the highest diversity (D= 0.860), followed by open area (D= 0.845) and forest area with the lowest diversity (D= 0.188). In conclusion, the beetle from genus Rhyncophorus sp. was the most distinct among other beetles due to the presence of snout and visible head which make it easier to identify. Beetle from genus Apogonia sp. was most found in sub forested areas due to high vegetation and medium sun exposure. Sample collection can be increased in future study by using dung trap sample collection and longer sampling time.

“…The complete forms of developmental stages of the population of rhinoceros beetle indicate overlapping generation. Manjeri, Muhamad, Faridah, & Tan (2013) reported that the rhinoceros-beetle population consists of overlapping generations. Multiple overlapping generations are common under favorable conditions such as in tropical countries.…”

The intensive and continuous collection of rhinoceros beetles, Oryctes rhinoceros L. (Coleoptera: Scarabaeidae), is an extraordinary strategy in IPM (Integrated Pest Management). This study was intended to evaluate the potency of people in collecting larvae and to determine the age structure of the beetle population. The study was conducted in Asahan Regency, North Sumatera Province. Adult men, adult women, adolescent girls, and adolescent boys collected beetles for 2 hours in each breeding site. Results showed that the beetle was more significant abundant in decomposed trunks at plots of immature and mature palms than at heaps of the empty fruit bunches namely 236, 221 and 93 individuals/2 hours. The population age-structure showed significantly predominant of 2 nd and 3 rd instars in all breeding sites, i.e. eggs, 1 st instars, 2 nd instars, and 3 rd instars, pupae, adult males, and adult females were 2.02, 23.29, 21.39, 47.06, 3.17, 0.86, and 2.21%, respectively. Adult men, adult women, and adolescent boys had similar potency in collecting 3 rd instar larvae while the least amount was collected by the adolescent girls viz. 70, 85, 60, and 38 larvae/2 hours, respectively. It is suggested that the study results support future efforts in the sustainable control of rhinoceros beetle through collecting larvae for commercial utilization.

“…Based on the use of randomly amplified polymorphic DNA (RAPD) markers [50] and randomly amplified microsatellite markers (RAMs) [53], the possible presence of two separate gene pools in O. rhinoceros had been reported. However, when a morphometric analysis of O. rhinoceros was performed [54] it revealed that the beetles are morphologically indistinguishable; consequently strengthening the need for further molecular analysis of the insect. Hence, to obtain more concrete results, species specific codominant single locus DNA microsatellite marker were for O. rhinoceros [55].…”

Oryctes rhinoceros, commonly known as the rhinoceros beetle is an important agricultural pest that is known to inflict serious damage on young oil palm trees. Many researches have been conducted on its development, life cycle, habitat, management and genomic variation ever since the need to understand this pest arose. Oryctes rhinoceros is among the longest present agricultural pest in Malaysia and it has witnessed the formulation and implementation of various phases of control and management strategies. To date, research and development activities are still ongoing in Malaysia for the successful management of this pest. In this review, we look into details on the characteristics of this pest, the modes of its introduction into Malaysia, as well as the events that helped to establish and contribute to the proliferation of this pest as a major oil palm threat in Malaysia. The progressive development of various research and development activities concerning the management and control of this pest are also highlighted.
