Soil fauna diversity on the area with several treatments on the oil palm trunk

Abstract

This study aimed to assess the fauna present on plantation land with various treatments of oil palm trunks after being cut.. Treatments of oil palm trunks included (i) palm trunks left in the form of logs; (ii) oil palm trunks were chopped after being cut; and (iii) oil palm trunks were removed from the plantation area. Macrofauna sampling was done by the method of pitfall trap, squared and hand sorting. Mesofauna samples were taken using the Berlesse-Tullgren Funnel method. The results found a variety of macrofauna belonging to 2 phyla, 5 classes, 9 orders, 10 families and 10 species. The value of total macrofauna population density for the treatment palm trunks left in the form of logs was 5115.18 individuals m−2, for chipping treatment was 8010.04 individuals m−2, and a for the treatment palm trunk removed was 2843.47 individuals m−2. Mesofauna obtained in this study belonging to 1 phylum, 5 classes, 1 sub-class, 13 orders and 22 families. The total population density of the mesofauna family for the treatment palm trunks left in the form of logs was 1120 individuals m−2, for chipping treatment was 1200 individuals m−2, for logging treatment was 880 individuals m−2.

The presence of Myopopone castanea Smith (Hymenoptera: Formicidae) as a predator in oil palm plantations

“…The degree of acidity of a substrate will influence the work of microorganisms in the wood weathering process. The wood weathering process involves the activity of a number of microorganisms such as bacteria, fungi [26], and several types of insects [27]. In general, ants prefer a neutral pH value for their life [25,26].…”
