Abstract

Indonesia is one of the countries with a lot of fruit diversity, one of which is bananas. Indonesia itself does not have a standard of banana productivity, but in the center of the world banana productivity of 28 tons / ha / year, only economical for household-scale plantations. Economical productivity for small plantations (10-30 ha) and large plantations (> 30 ha), should reach at least 46 tons / ha / year. This shows that the productivity of bananas in Pontianak Regency of 25.93 tons / ha is still below the economic productivity standard of at least 28 tons / ha / year if in the form of household-scale plantations. The attack of disease pests can reduce the productivity of bananas. One of the important diseases of banana plants is banana dwarf disease (Banana Bunchy Top Virus) Caused by the Bunchy Top virus. Bunchy top diseases have spread across countries such as Europe, Africa and Asia. This banana dwarf disease is transmitted by vector insects, namely banana tick Pentalonia nigronervosa. The study therefore aimed to determine the ability of the kecombrang plant to be an alternative host for P. nigronervosa, and the study also aimed to look at the level of infectiveness and efficiency of P. nigronervosa after skipping time in the torch ginger plant. This research was carried out in the experimental garden and in the laboratory of the Department of Pests and Plant Diseases, Faculty of Agriculture, Sriwijaya University in August to December 2021, With biological test experiments of P. nigronervosa ticks on torch ginger on water media given 5 imago P. nigronervosa on propagation media then moved each newborn nymph to a repeat plant and repeated 10 times, the collected data in the form of life cycle data and population average value, while for the infectiveity test of lice on bananas using a randomized group design (RAK) performed 4 treatments and 5 repeats with 3 plants per unit of treatment. The data obtained is processed in ANOVA (Analysis of Variance). The results showed that P. nigronervosa were able to live and reproduce on torch ginger plants on water media, P. nigronervosa aphids had a life cycle of 26 days on torch ginger plants and each imago produced an average of 22 nymphs. But for the infectiveity test of the tick P. nigronervosa, showed no different results. The torch ginger plant is unable to reduce the infectivity of P. nigronervosa ticks in transmitting the banana dwarf virus. The percentage of attacks on bananas is no different. In conclusion, P. nigronervosa aphids are able to live on torch ginger plants, but torch gingers are not able to reduce the infectivity of lice in transmitting banana dwarf virus disease.
