The presence of ladybug beetle (Coleoptera: Coccinellidae) as a predator on agriculture in Jambi region

The results showed that 13 types of ladybugs beetles were present in several agriculture cultivation in the Jambi region, namely; Epilachna sp. Verania discolor Fabricius, Verania lineata Thunberg, Coelophora reninplagiata Mulsant, Coelophora 9 muculata Thunberg, Coccinella arcuata Fabricius, Chilomenes sexmaculata Fabricius, Heteroneda reticulata Fabricius, Harmonia (Callineda), Micromedicata, Microticata. There were 3405 individuals of ladybugs beetles, with the most common species was the Epilachna sp. and the fewest species found were Heteroneda reticulata. Diversity indices at each station were station I (2.20), II (1.89), III (1.78), IV (2.17), and station V (2.05). The highest diversity index of ladybugs beetles species is at station I and the lowest diversity index is at station III. The diversity of ladybugs beetles in all stations shows the criteria of moderate diversity. Dominance index at station I (0.11), II (0.20), III (0.20), IV (0.13), and V (0.16). The highest dominance index at station II and III has the same dominance index value, and the lowest dominance index at station I. All stations have the same criteria, which indicates that no species dominate. For the evenness index at station I (0.95), II (0.76), III (0.81), IV (0.87), and V (0.85). Highest evenness index was at station I, and low evenness index was at station II. All stations indicate that the evenness index has moderate evenness criteria that indicates a stable community.
