Diversity of Predatory Arthropods In Two Cocoa (Theobroma cacao L.) Habitats In Pemepek Village, Central Lombok Regency

This study aims to determine the diversity of predatory arthropods on cocoa plants (Theobroma cacao L.) as part of a sustainable biological control approach. The research was conducted at two smallholder farm locations in Pemepek Village, Central Lombok Regency, from May to June 2025. The methods used were field surveys and specimen collection using pitfall traps, beating trays, yellow pans, and brocap traps, followed by laboratory identification. The results showed a total of 704 predatory individuals, originating from 10 orders, 34 families, and 99 species. Location 2 had a higher number of predatory individuals (487) compared to Location 1 (217). The Shannon-Wiener diversity index (H’) values were 3.309 for Location 1 and 2.637 for Location 2. The dominance index (C) values were 0.127 (low category) and 0.074 (low category) for Locations 1 and 2, respectively. The evenness index (E) values were 0.427 (low category) for Location I and 0.273 (low category) for Location 2.
