ABSTRACT

Toxoptera aurantii is an insect and pest that is important to control the orange plantation because not only botch the plant, but also it can be the tristeza (CTV) and (CVEV) vector, and can help Capnodium sp. stimulation, which causes the sooty mold disease which reduces the production of oranges number. An entomopatogen Verticillium sp. which is one of the biological agency can be used at pest control inwrought (PHT) toward pests from Homoptera and Hemiptera ordo. One of them is T. aurantii. an insect pest research has been done based on what was mentioned a patogensitas Verticillium sp. toward imago T. aurantii. The aim from this research is to know effectivenes of Verticillium sp. toward imago T. aurantii. This research is done according to the experimental use of a complete random plan (RAL). Treatment uses Verticillium sp. suspension with concentration of 0g/100ml (K0), 2g/100ml (K1), 4g/100ml (K2), and 6g/100ml (K3). Each treatment use sample T. aurantii as many as ten and repeats as much as 6 times. Observation was done towards the death of imago T. aurantii, that given treatment using insect patogen. The result from the observation shows that Verticillium sp. influences the death of imago T. aurantii, although the highest mortality is achieved at only 28.3%. The death of T. aurantii in treatment use Verticillium sp. with concentration 2g/100ml, 4 g/100ml and 6g/100ml successive 13.3%, 28.3% and 20%, while controle doesn't show the death existence because Verticillium sp. infection.
