ABSTRACT
Pest control for oil palm trees still using the insecticide, the toxic materials could lead the killing of parasitoid and predator. Various types of parasitoid and predator founded on oil palm crops, such us predatory of Sycanus dichotomusas pest predatory of fire caterpillar and bagworm. Various way conducted to incline the role of predator to push the development of pest, such as adding the number and releasing the predator into field area. Provision of predator in big number conducted with mass breeding. Many research about propagation of S. dichotomus with using the feed of Tenebrio molitor, however, never known the propagation of S.dichotomous using the T.molitor which integrated with natural feed or artificial. This research aiming to propagate S. dichotomous using the T. molitor and Oecophylla smaragdina also honey. Other wise the maintenance using the simple tools such as jar and glass cage. The parameter which used, namely; the percentage of development of S. dichotomous in the egg stadia, nymph and the ability of female imago producing the eggs.
The research conducted in Pest Laboratory of Universitas Sumatera Utara with the temperature around 25-30°C and the humidity were 70-80%. The rearing conducted with caring 15 nymphs, 15 couple of imago of S. dichotomus, and 15 eggs’ group. Nymph stadia of instar 1 of S. dichotomous given the honey feed, nymph of instar 2 given the egg of O.smaragdina and honey, also the nymph of instar 3 until instar 5 and imago stadia given the fly bow nymph of T. molitor and honey. The development of nymph of instar 1 to instar 2 and nymph of instar2 became instar 3 for each amount 93-95%. The development of nymph of instar 3 to instar 4 amount 90-93%, however, nymph of instar 4 changed into nymph of instar 5 only reaching 70-75%. A couple of S. dichotomous producing as much 3-4 groups and as much 60-80 eggs for each group, and the changes of eggs stadia became nymph reacing 95-96%.
