  • Hestina Br. Ginting,” Efectiveness Tess of any Natural Insecticide to P.xylostella L. and C. binotalis Zell. on Cabbage (B. oleracea L.)”. This research was held in field Balai Penyuluhan Pertanian (BPP) Kabupaten Karo. Approximately ±1.250 meter from the sea surface. This research used non factorial Random Group Design, consis of six treatments that was MO1 (control), MO2 (insecticide), M1 (Annona muricata L extract), M2 (Ageratum conyzoides extract), M3 (Azadirachta indica extract), M4 (Andropogon nardius extract) with four replication. The parameters observed were population number of P.xylostella L. and C. binotalis Zell., attack percentage of P.xylostella L. and C. binotalis Zell., and production of cabbage. The result showed that the highest population number of P.xylostella L. was 20.31 tail and C. binotalis Zell. was 27.40 tail, the lowest was 4.19 tail (P.xylostella) and 6,55 tail (C. binotalis). The highest attack percentage of P.xylostella was 60.32% and C. binotalis was 40.13%, the lowest was 11.17% (P.xylostella) and 8.38% (C. binotalis). The highest production of the cabbage was 35.64 ton/ha and the lowest was 28.74 ton/ha.
