Abstract

One of the important factors that could potentially lower the production of sugarcane plantations in Indonesia is the pest infestation. The mayor pest of sugarcane are sugarcane top borer (Scirpophaga nivella), sugarcane stem borer (Chilo aurichilius), rats and sugarcane scale insect (Aulacaspis tegalensis.). Scale pests of sugarcane in the last decade increased in areas of Sumatra. The attack of sugarcane scaleinsect on the sugarcane plantations of PT Gunung Madu Plantations, Central Lampung is almost evenly in estate area with a strike rate of over 18 percent. This research aimed to get potential predators forbiological control of sugarcane scaleinsect. The experiment was carried out in the sugarcane field and Entomology Laboratory of PT Gunung Madu Plantations (PT GMP),Gunung Batin, Lampung Tengah, in April 2015 until May 2016. As many as 10 individuals of adult predators were placed in plastic jars, 9 cm in diameter. This experiment was arranged in a randomized Complete Design with six treatments and 3 replicates. Treatments were feeding in the form of P1 (100 individuals of sugarcane scale insect ); P2 (200 individuals of sugarcane scale insect); P3 (300 individuals of sugarcane scale insect); P4 (100 individuals ofaphids); P5 (200 individuals ofaphids), and P6 (300 individuals ofaphids). The observation was done every day, when the remaining 50% of feed was replaced with the new feed. One character of the predator was desired in that it had the ability to survive with both the original and alternative feeds. Predators that were found in sugarcane plantations, PT Gunung Madu Plantations were , among others,Chilocorussp., Telsimiasp. and Scymnus spp.The experiment showed that when fed with sugarcane scale insect, Chilocorus sp. survivedfor 27.2 days, Telsemia sp. 4.1 days and Schymnus sp. 27.8 days. When fed with.alternative feeds (white sugarcaneaphids) Chilocorus sp was able survive for 7.1 days,Telsemia sp. survive 4.1 days and Schymnus sp. 8.1 days.
