| Sumario: | The research was conducted in the field of Taro village Gianyar regency and Katung village Bangli regency and at the Laboratory of Biotechnology Faculty of Agricultural Udayana University. The purpose of the research were to investigate population dynamic of <em>Diaphorina citri</em> Kuwayama and other insects that were assosiated with citrus cv. siam; and molecular detection of CVPD patogen in its vector, other phytophagous insects on citrus cv.siam and kemuning [<em>Murraya paniculata</em> (L.) Jack.] The result of this study showed that in six month period there was one peak of <em>D. citri</em> population which was associated with the flushing period of citrus at Taro as well Katung villages. The peak of <em>D. citri</em> population of Taro village was higher than that of Katung village. Two species of parasitoids and four spesies of predators were found in the field and may contribute in the suppression of <em>D. citri</em> population. The parasitoids identified were <em>Tamarixia radiata</em> Wat. and <em>Diaphorencyrtus alligharensi</em> Shaffe, whereas the predators were<em> Curinus coeruleus</em> Mulsant, <em>Phiddipus</em> sp., <em>Menochilus sexmaculatus</em> Fabricius and <em>Oxyopes javanus</em> Thorell. <em>T. radiata</em> has been proven to be an effective nymph parasitoid that could suppress the population development of <em>D. citri</em> in citrus orchads. The research revealed that kemuning could serve as a source of infection because it is also a host of CVPD disease as well as of<em> D. citri.</em> <em>Toxoptera citricidus</em> Kirkaldy and <em>Maleuterpes dentipes</em> Hell. were not proven to contain CVPD disease. |
