Abstract

Outbreaks of the rice brown planthopper, Nilaparvata lugens Stal., tend to increase in 2017. There has been significant interest to reduce reliance on pesticides by manipulating habitat plant species and communities to benefit natural enemies of insect. Flowering plants as refuge can contribute in enhancing the ecosystem services. This study aimed to assess the benefit of flowering plants as refuge to improve the role of egg parasitoids of brown planthopper. We sampled three rice fields: rice field adjacent to refuge, far from refuge, and rice field with no refuge using trapping procedure. We found two genera of parasitoid in Banyumas: Oligosita and Anagrus. The parasitism in the three rice fields was 46.14, 43.05 and 42.32%, respectively, showing no differences. However, the number of parasitoids emerged from the traps placed in the rice field with refuge was higher (31.08 adults/trap) than the other two rice fields (25.67 and 20.71 adults/trap). In addition, the number of unhatched parasitoids was lower in the rice with refuge (5.9%) compared to no refuge (14.54%). These findings show that the refuge provides better environments for the parasitoid by improving the number of progeny produced which eventually could increase their role in managing N. lugens population.

Abstract

The field schools in Indonesia employ an extension alternative model that is considered appropriate to change the habits and behavior of farmers to make them IPM experts in their field. This study was conducted to understand the behavior (knowledge and attitude) of farmers who have joined field schools, i.e. Integrated Pest Management Farmers Field School (IPM-FFS) and Landscape Integrated Pest Management (Landscape IPM), toward the use of pesticides in Klaten, Central Java, Indonesia. The research used a survey method with purposively selected respondents comprising 55 farmers of the IPM alumni and 25 farmers of the Landscape IPM alumni. A descriptive analysis was conducted to analyze the farmers’ knowledge and attitude toward the use of pesticides. Mann-Whitney U-test analysis was performed using Statistical Product and Service Solution (SPSS) version 23, to compare the knowledge and attitude of farmers regarding the use of pesticides. The results showed that the knowledge of farmers of  the Landscape IPM alumni regarding the use of pesticides was higher than that of farmers of the IPM-FFS alumni. There was no difference in the behavior of farmers between the IPM-FFS alumni and the Landscape IPM alumni regarding their attitude toward the use of pesticides.

Abstract

High-yielding varieties are used as one of the technologies to increase rice productivity in Indonesia. Varieties, however, invite the arrival of arthropod during their growing phase. One of the method to manage arthropods during the growing stage is the use of high-yielding varieties. In this trial, IR-64, Ciherang, Situ Bagendit, Mekongga and Mixed Varieties were used. The mixed variety is a combination of IR-64, Ciherang, Situ Bagendit and Mekongga. These rice varieties are the most common varieties used by farmers in Bantul Regency. To collect arthropods, the traps used were sweep net, yellow sticky and pitfall traps. The purpose of this study was to determine arthropod’s diversity, evenness and dominance in different rice plant varieties in one planting season. The study was conducted in the village of Wijirejo, Pandak, Bantul, Yogyakarta. The observations were conducted in the evening between 16.00–18.00 p.m., with the interval of twice a week for 5 observations. Arthropods were identified up to the family level. This research resulted in the diversity index (Shannon-Winner) of 1.97–2.82 which is categorized as medium, the evenness index of 0.61–0.71, categorized as medium and the dominance index of 0.10–0.22, categorized as lower level. The ecosystemof the research area was unstable in diversity, evenness, and dominance due to the transition process, and it took quite some times to stabilize the rice fields. Therefore, a more thorough research is still necessary, especially for the ricegrowing season to follow.
