Diversity and Composition of Arthropods Natural Enemies in Integrated Rice Fish Farming System (Minna padi) and Its Functions in Agroecosystems

Abstract

Minna Padi is an integrated rice fish farming system that implements environmentally friendly cultivation and creates a sustainable ecosystem. However, the effects of minna padi farming systems on the diversity of natural enemies have not been reported previously. This research was conducted to compare the diversity and abundance of natural enemies [parasitoids and predators] in minna padi and conventional rice fields. Three pairs of minna padi and conventional paddy fields were selected for fields research. Natural enemies were collected in the field research using sweeping nets, yellow sticky traps and pitfall trap every two weeks during the cultivation. The results showed that the abundance of parasitoids was higher in minna padi than that in conventional farming systems. However, the abundance of predators was higher in conventional farming systems. Parasitoid and predator species richness also showed no difference between the two rice farming systems. However, the composition between the two farming systems was different, minna padi was dominated by parasitoids such as Aphonagmus sp. and Eurythoma dentata, while conventional dominated by a predator such as Pardosa pseudoannulata and Plexippus sp.

Diversity and community structure of predators in surjan (polyculture) and lembaran (monoculture) paddy fields

“…The raised beds are the elevated, terrestrial areas for cultivating palawija or horticultural crops, while the sunken beds are lower, aquatic areas for rice production (Susilawati & Nursyamsi, 2014). The surjan system can promote ecological balance because the variety of plants increases the diversity of pests that serve as prey for predatory insects, thereby increasing the diversity of predatory insects (Aminatun et al, 2014;Trisnawati et al, 2022a).…”

“…The presence of predators contributes significantly to the maintenance and improvement of the ecosystem balance (Mortuja et al, 2021;Tiwari et al, 2021). The agricultural system impacts both the species richness and the abundance of predators (Nurkomar et al, 2023;Trisnawati et al, 2022a). Polyculture production techniques may enhance the role of predators and parasitoids as natural controllers of pest populations, exemplifying the growing recognition of the functional interactions represented by natural enemies (Greenop et al, 2018;Staab & Schuldt, 2020;Straub et al, 2014).…”

Effect of different feed nitrogen on nutrient flow, performance, and productivity in the minapadi system

“…Thus, Minapadi increases the availability of nutrients for rice plants and increases the content of organic matter originating from the decomposition of feed residues and weeds, which are financially beneficial for farmers with low inputs and promotes environmental friendliness; the main objective of Minapadi farming system is to increase the productivity of paddy fields, implementing sustainable cultivation and creating a sustainable ecosystem [3]. Minapadi uses fish waste as nutritional fertilizer,…”

Soil bacterial community composition in rice-turtle coculture systems with different planting years

“…Thus, the soil microbial community can be used as an indicator to track changes in various land management methods, such as tracking changes in restoration outcomes 8 . Many studies have demonstrated that the rice-fish integrated farming patterns could increase the number and community diversity of soil microorganisms 9 – 11 , especially bacteria that play a crucial role in soil carbon and nitrogen mineralization 12 . Proteobacteria, Bacteroidetes, Acidobacteria, and Chloroflexi were generally dominant phyla in the paddy soil.…”
