Use pheromone traps with rhinolure 12/ha for trapping the adults and destroy them. Place some napthalene balls at leaf axil at the top of the crown Place phorate 10 G 5 gms mixed with sand in two inner most leaf axils for 2 times at 6 months' intervals. Apply mixture of neem seed kernel powder + sand (1:2) at150 g per palm in the base of the 3 inner most leaves in the crown Metarhizium anisopliae can be applied in manure pits at 4 kg/tonne to control the grubs that feed on the decaying matter A hooked wire can be used to extract and destroy rhinoceros beetle adults feeding in coconut trees. Cut stumps as close to the soil surface as possible. Chop and burn decaying logs or break them up and destroy any adult beetles developing inside. Adults may live for 4-9 months and each female lays 50-100 eggs during her lifetime. Mostly mating takes place at the breeding sites. They are active at night and hide in feeding or breeding sites during the day. The pupal stage lasts for 17-28 days.Īdults remain in the pupal cell for 17-22 days before emerging and flying to palm crowns to feed. The larvae stage takes another 82-207 days before entering an 8-13 day non feeding prepupal stage. When the leaves grow out and unfold, the damage appears as V-shaped cuts in the fronds or holes through the midrib.Įggs are laid and larvae develop in manure pits or other organic matter and hatch in 8-12 days. The beetles damage palms by boring into the centre of the crown, injuring the young growing tissues and feed on the exuded sap.Īs they bore into the crown, they cut through the developing leaves. The beetles will still obtain all the necessary nutrients they require from the jellies and have many benefits including their long shelf life and the fact they do not attract fruit flies.Rhinoceros beetle is mainly a pest of coconut and oil palms. Adult Rhino Beetles naturally feed on fruit and tree sap however in captivity it is commonly accepted to feed your adult beetles solely on beetle jellies. To make things simple we also offer a ProRep Rhino Beetle Rearing Kit which is suitable for both raising larvae and keeping small adults singular. Climbing furnishings can be added to the terrarium along with live moss. When considering a terrarium remember that you need to provide a substrate depth of 20cm or more and with an optimum substrate mix of ProRep Beetle Grub (Type 1) and (Type 2) in the ratio of 2:1. Humidity needs to be maintained around 70-80% but remember that you are looking to keep a damp but not wet substrate.Īdult Rhino Beetles can be housed in suitable plastic or glass terrariums either singular, in pairs or in sexed groups. Heat mats should not be used with Rhino Beetles as they naturally bury themselves into the cool ground to escape heat and secondly it will also lead to the desiccation of the substrate. Temperatures should be kept within the range of 20-25 ☌ for most species. ![]() However natural daylight entering into the room where your animals are kept is advisable to provide a natural photoperiod. ![]() Rhino Beetles are nocturnal animals and do not require any special heating/lighting equipment. There is also one species found in Europe (Oryctes nasicornis). Rhino Beetles are found throughout Central, South America, South Asia and Africa. Female Rhino Beetles are usually smaller bodied than males.Īdult Rhino Beetles bodies are ordinarily a muted colouration of black, brown, green or red however there are some colourful exceptions such as (Dynastes granti) or ( Eupatorus gracilicorni). These are commonly used in territory disputes with other males over mating sites or food. ![]() ![]() Rhino Beetles are sexually dimorphic with males having characteristic horns. There are over 300 known species of Rhinoceros Beetles or Dynastinae with the biggest ones reaching lengths of up to 17cm, however this size is rare among captive specimens.
