Abstract

Abundance and Potential of Erionata thrax L (Lepidoptera; Hesperidae) as an Insect Vector Ralstonia syzygii subsp. celebesensis Cause of Bacterial Blood Disease in Barangan in Deli Serdang Regency North Sumatera. This study was conducted to determine the abundance of Erionata thrax and its potential as an infectious agent for Ralstonia syzygii subsp. celebesensis on Barangan plants. The research was conducted by using the survey method, taking samples of eggs, larvae, pupae, and imago E. thrax as many as 60 samples from Barangan plants in Sampali village, Percut Sei Tuan District, Deli Serdang Regency and isolation of Ralstonia syzygii subsp. bacterial. celebesensis in the Laboratory of Agriculture, Faculty of Agriculture, Medan Area University. The results showed that the percentage of E. thrax attacks on Barangan plants reached 100 percent in the rainy season. In Barangan plantations, there were found various phases of E.thrax development ranging from eggs, larvae (L1, L2, L3, L4, L5, and L6), pupae and imago. Propagul Ralstonia syzygii subsp. celebesensis is only found in E.thrax imago.
