Cockroach Identification and Relative Abundance in Meat Stalls at Pasar Bogor

Abstract

This study aimed to identify cockroach species morphologically and quantitatively measure cockroach relative abundance in meat stalls at Pasar Bogor. A quantitative observational design was used from March to May 2025. Five meat stalls were selected purposively, and cockroaches were collected through direct observation, sticky traps, and manual collection. Species were identified morphologically using a digital microscope, while infestation was analysed using relative abundance, Shannon–Wiener Diversity Index, microhabitat distribution, and trap-based abundance. Three species were identified: Periplaneta americana, Periplaneta brunnea, and Nauphoeta cinerea. A total of 351 cockroaches were collected, dominated by N. cinerea (59.83%). The diversity index was low (H' = 0.556), and cockroaches were mostly observed on walls (44.16%).

Penelitian ini bertujuan mengidentifikasi spesies kecoa secara morfologi dan mengukur kelimpahan nisbi kecoa secara kuantitatif pada lapak daging di Pasar Bogor. Penelitian menggunakan desain observasional kuantitatif pada Maret hingga Mei 2025. Lima lapak daging dipilih secara purposif, dan kecoa dikoleksi melalui observasi langsung, perangkap lengket, serta koleksi manual. Identifikasi spesies dilakukan secara morfologi menggunakan mikroskop digital, sedangkan infestasi dianalisis menggunakan kelimpahan relatif, Indeks Keanekaragaman Shannon– Wiener, distribusi mikrohabitat, dan kelimpahan berbasis perangkap. Tiga spesies diidentifikasi, yaitu Periplaneta americana, Periplaneta brunnea, dan Nauphoeta cinerea. Sebanyak 351 kecoa dikoleksi, didominasi oleh N. cinerea (59,83%). Nilai indeks keanekaragaman rendah (H' = 0,556), dan kecoa paling banyak diamati pada dinding (44,16%).
