Abstract
Aims: The study aimed to study the abundance and biodiversity of Coccinellid predators in rice field Ecosystem in Payakumbuh District, Lima Puluh Kota Regency, West Sumatera, Indonesia.
Study Design: Purposive random sampling.
Place and Duration of Study: The research was conducted in rice field of Payakumbuh District, Lima Puluh Kota Regency, West Sumatera and Laboratory of Pest, Faculty of Agriculture, Riau University, Pekanbaru, Indonesia from January to April 2022.
Methodology: Purposive random sampling was used in the research. Three rice fields in Payakumbuh District was chosen as sampling locations. Sweep net method was using to collect the coccinellid and the collected coccinellids were identified in Pest Laboratory, Faculty of Agriculture, Riau University, Pekanbaru, Indonesia. The data was analyzed by using Shannon-Winner diversity index to analyze biodiversity and evenness index.
Results: 30 individuals of three species of coccinelid predators were found in rice field ecosystem in Payakumbuh district. The species were Micraspis lineata (20 individuals), Menochilus sexmaculatus (9 individuals) and Coleophora bisselata (1 individual). The species diversity index (H’) and species evenness index (E) were 0.73 and 0.66 respectively.
Conclusion: The diversity of coccinellid predators in rice field in Payakumbuh district was quite stable and more stable.
