The Preference Of CVPD Vector (Diaphorina citri) On Various Dominant Weeds

Citrus vein phloem degeneration (CVPD) is the most impediment disease in citrus production in the world. It mainly vectored by Diaphorina citri Kuwayama. Intensive application of insecticides is ineffective and also costly. Various weeds species in citrus orchard is suspected as alternative host of vector. Research on the preference of D. citri on the various weeds is needed for completing the integrated CVPD disease management program. Five dominant weeds gained from vegetation analysis were arranged randomly in circular fashion inside the nylon mess cage and D. citri adult which previously starved for 24 hours were released in the middle arena. The position and number of D. citri were recorded daily (24h) for seven days. Analysis of variance and DMRT were done on data. Most of D. citri stayed for feeding on Boerhavia erecta (52.67%), and it was significantly different to Amarantus spinosus (15.67%), and also to Althernanihera philoxeroides (0.33%), Portulaca oleracea (033%), Ludwigia perrenis (0%)
