Abstract
Citrus vein phloem degeneration (CVPD) is the most impediment disease in citrus production in the world. lt is mainly vectored by Diaphorina citri Kuwayama. Intensive application of insecticides is ineffective and also costly. Various weeds species in citrus orchard are suspected as alternative host of vector. Research on the longevity of D. citri on the various weeds is needed for completing the integrated CVPD disease management program. Each of five dominant weeds gained from vegetation analysis were exposed to five days old D. citri adults inside the nylon mesh cage, which previously starved for 24 hours. The number of D. citri survived was recorded daily (24 h). Analysis of variance and DMRT were done on data. Most of D. citri stayed for feeding on Boerhavia erecta and survived for 5,91 days. It was significantly different on Amaranthus spinosus, and also on Althemanthera philoxeroides, Portulaca oleracea, Ludwigia perenis which survived for 3.57, O.20, 0.00, and 0.20 days respectively.
