The distribution of root and bulb parasitic nematode in garlic crops at various elevation and the effect of abiotic factors on their distribution were investigated. The survey was done at the centers of garlic production area in Central Java, Indonesia. Soil abiotic factors such as temperature, pH, and C-Organic were measured in each location of sampling. Nematodes were analyzed using incubation and white head tray technique modification. Correlation and regression were used to determine the effect of abiotic factors. The results showed that the five locations with different elevations were positive for Ditylenchus dipsaci distribution. These nematodes were found in various elevation with different populations in the range of 8.00-16.67 nematodes per 100 g of soil and 14.34 to 26.67 nematodes per 2 g of bulb. The highest density of the nematode population both in bulb and soil was in Tegal at elevation <1000 m a.s.l. while the lowest nematode population both in soil and root were found in Temanggung at an elevation of 1000-1200 m a.s.l. Abiotic factors, such as temperature has a positive correlation with D.dipsaci nematode populations in bulb and soil, while pH has a negative correlation with nematode populations. C-organic has a positive correlation in abundance of nematode populations in the soil and negative in abundance of nematode populations in bulb.

White tip disease on rice caused by Aphelenchoides besseyi is categorized as emerging infectious disease in Indonesia because the disease incidence and its geographical distributionare increasing rapidly. Until presently, there is no information related with mass culture technique of Ap. besseyi in Indonesia. Thus, studies to obtain pure population of Ap. besseyi are necessary to be conducted to support various research aspects in the future. This research is aimed to study Ap. besseyi pure mass culture technique by rearing the nematode on three fungal species. Three different fungal cultures on PDA medium, i.e. Alternaria padwickii, Fusarium semitectum, and Botrytis cinerea were tested as Ap. besseyi cultivation media. To obtain the optimum condition for nematode cultivation, the fungal cultures were incubated in three different temperature. The nematodes were surface sterilized with 0.1% streptomycin sulfate followed by washing with sterilized water before infesting the nematode into fungal culture. Subsequently, 25 sterilized nematodes were infested into 7 days old of fungal culture and incubated at 20ºC, 25ºC and 30 ºC. After 21 days, nematodes were harvested and counted the final population. Among fungal species tested as rearing medium, the best culture for Ap. besseyi reproduction was on Al. padwickii culture at 25 ºC with average final population up to 9,115 per petri dish and reproduction factor 364.6. At a 30ºC, Ap. besseyi was failed to develop its population in all the fungal cultures tested. It indicated that the optimum temperature for reproduction of Ap. besseyi on those of fungal species was 20-25 ºC.
