Abstract

Studies on the population and species composition of fruit flies on bird's eye chili plants are still needed to support more effective control efforts. This study aimed to examine the population abundance and species diversity of fruit flies (Bactrocera spp.) associated with bird's eye chili (Capsicum frutescens L.) and to identify the most effective trapping method at the Experimental Garden of the Faculty of Agriculture, Sriwijaya University. Observations were conducted over eight weeks using various trapping methods, with parameters including species diversity, species dominance, and species evenness. The data obtained were analyzed using ANOVA followed by DMRT at the 5% significance level. The study successfully collected 6,689 fruit fly individuals representing three species: Bactrocera dorsalis, B. carambolae, and B. umbrosa. B. dorsalis was the most abundant species, accounting for 4,474 individuals (67%) across all trapping methods, followed by B. carambolae (1,607 individuals) and B. umbrosa (608 individuals). Analysis of variance and DMRT (5%) revealed significant differences among trap types: the Yellow Sticky Trap yielded the highest catch, with an average of 206 individuals per week, compared to the Methyl Eugenol Trap (70 individuals per week) and the sweep net (2 individuals per week). These results indicate that the Yellow Sticky Trap has the potential to serve as a key component in environmentally friendly fruit fly monitoring and control strategies for bird's eye chili cultivation. Consequently, the use of Yellow Sticky Traps could be a valuable component of eco-friendly fruit fly management strategies in horticultural cultivation systems.

Abstract

Maize and chili polyculture systems have the potential to enhance agroecosystem productivity, but their effectiveness is strongly influenced by the dynamics of arthropods, including phytophages, predators, parasitoids, decomposers, and pollinators. This study inventoried arthropod communities by analyzing the abundance of ecological groups and calculating diversity, evenness, and dominance index. The aim was to provide an ecological foundation to strengthen integrated pest management and support the implementation of sustainable agriculture in line with Asta Cita's development direction. The research was conducted at the Agro Training Centre, Faculty of Agriculture, Sriwijaya University. To obtain samples in the maize–chili polyculture system, several types of traps were used, including yellow sticky traps, methyl eugenol traps, pitfall traps, pan traps, light traps, sweep nets, and visual traps, which were placed in each planting bed. All traps except the light trap were installed between 06:00 and 07:00 and operated for 24 hours, except for the light trap, which was installed at 18:00 and operated for 12 hours. The diversity index obtained was H' = 1.15, indicating a medium category; the evenness value (E = 0.48) showed that species distribution was uneven; and the dominance index (D = 0.30) suggested the presence of a sub-dominant species. The most frequently captured species was Bactrocera sp 1, belonging to the order Diptera and functioning as a phytophage. Clustering analysis indicated a correlation between Bactrocera sp 1 and Bactrocera sp 2. Overall, the dominant arthropod functional group in the maize–chili polyculture system was phytophagous species.
