“…Phosphorus modulates the activities of enzymes and aids in lipids, proteins, nucleic acids, and carbohydrate metabolism (Omotoso, 2015). The Iron concentration of O. rhinoceros was less compared to the value of Z. variegatus (1.20 AE 0.16 mg/100g; 2.32 AE 0.06 mg/100g respectively), and likewise lower than the value reported by Okaraonye and Ikewuchi (2009) for the same insect (4.50 mg/100g). Iron is an antioxidant which prevents cardiomyopathy and growth retardation (Buss et al, 2003) and Each value represents the mean AE SD (n ¼ 3).…”

Considerably large quotas of insect species worldwide are prospective sources of food with high nutrient value, which suggests their importance in human diets. This study investigates and compares the nutrient and anti-nutrient contents of Oryctes rhinoceros larva and Zonocerus variegatus . The nutrient and anti-nutrient compositions of both Oryctes rhinoceros larva (palm beetles) and Zonocerus variegatus (grasshopper) were determined following standard procedures. The proximate results revealed that Oryctes rhinoceros had higher amounts of crude protein (34.76 ± 0.44%) and carbohydrate (10.37 ± 1.73%) compared to those in Zonocerus variegatus ((30.73 ± 1.15%) and (5.36 ± 2.15%) respectively), while crude lipid (20.00 ± 0.00%) was higher in Zonocerus variegatus . Rich mineral components were also obtained in both insects. Potassium and sodium (1905.01 ± 185.01 mg/100g and 1656.00 ± 46.00 mg/100g) were moderately high in Zonocerus variegatus compared to Oryctes rhinoceros (1070.00 ± 260.00 mg/100g and 931.50 ± 11.50 mg/100g), while calcium (368.00 ± 16.00 mg/100g) was comparably higher in Oryctes rhinoceros . The anti-nutrient values of both insects fall within tolerable levels, and subsequently pose no threat to life, indicating that these insects are good sources of several macro and micronutrients. Oryctes rhinoceros , however, may likely serve as a better source of nutrients, considering its more valuable contents of macromolecules.

“…Likewise, for larvae collectors, insofar as rhinoceros beetle larvae have promising economic value, they are motivated to hunt larvae and sell them. Among the various stages of rhinoceros beetle, 3 rd instar larvae are the most selected stage to be processed into bagworm foods, feeds, or others (Okaraonye & Ikewuchi, 2009). Table 1 shows that the 3 rd instar larvae can be obtained in the three breeding sites.…”

“…Rhinoceros beetle larvae have the potential to be made into food because they are highly nutritious; protein (42.29% wet weight), unsaturated fatty acids (60.34%), and ash (12.70% wet weight) including manganese, iron, calcium, magnesium, potassium, sodium, copper and phosphorus. The larvae are boiled, smoked, or fried and consumed as a snack or side dish (Okaraonye & Ikewuchi, 2009). Therefore, it is possible to develop the utilization of the larva toward commercial propose.…”

“…Shelomi, Lin, & Liu, (2019) reported that the gut microbiota of O. rhinoceros larvae is quite similar to that of the termite gut, as both species feed on decaying wood. Moreover, the beetle larvae are suggested to be used as feed and food (Okaraonye & Ikewuchi, 2009;Omotoso, 2018). Therefore, usefulness of the larvae shall motivate ones to collect them.…”

“…Hunting larvae intensively and continuously is a strategic step for sustainable control of these pests. Utilization of rhinoceros beetle larvae is promising such as supported by Okaraonye & Ikewuchi (2009) and Omotoso (2018) that the larva is highly nutritious. This study treats hunters of this larvae are likely as a predator.…”

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.
