Abstract

There were ten processed wastes (molase, vinase, sludge, ciu, brem, tofu, milk, cacao, fish, and beer) used in these experiments. The experiments were conducted in two separated arrangements: no choice test and choice test. The no choice test was carried by testing the attractiveness of B. carambolae on each waste was compared with water. Each run consisted of four replication, for each replication consisted of 20 females and 20 males. The choice test was conducted by placing all wastes in a cage at the same time. Each run consisted of 15 replication, for each replication consisted of 100 females dan 100 males. The no choice test results showed that B. carambolae tend to visit waste more than water. The choice test results showed that B. carambolae tend to be more frequent visits to beer and cocoa waste. The content of protein inside the waste seemed to play role in attracting B. carambolae to come with.

Abstract

The objectives of this research were to determine the species composition, distribution pattern and virus transmission properties of N. virescens. Sweep net sampling of the leafhopper and others tungro vectors population were conducted from endemic areas in Central Java, East Java and Bali and also non endemic areas from Central Java and East Java. The species composition and distribution pattern of the leafhopper were studied in seedbeds and early stage of rice crop (30 days after transplanting). Inoculation test using Cisadane seedlings was conducted to determine the efficiency of virus transmission by N. virescens colonies. Four tungro virus vectors were found in all areas, namely N. virescens, N. nigropictus, N. malayanus, and Recilia sp. The domination of N. virescens occurred either in the endemic area or the non endemic areas. However, the domination of N. virescens did not correlate with the occurrence of the disease in the endemic area. The distribution pattern of N. virescens was regular. The number of N. virescens active transmitter in the endemic area was higher than that in the non-endemic areas. In addition, the female of N. virescens was more efficient in transmitting the tungro virus than that of the male.
