Termites are perceived as decomposers and as pests in an ecosystem. A study on the species composition of termites in different soil types (i.e. clay, sand and peat) in oil palm plantations was conducted between 6 April 2015 and 10 December 2015 in nine selected localities in Johor (Malaysia) and Riau (Indonesia). Sampling of termites was conducted using belt transects of 100 m in length and 4 m in width in the oil palm plantation. A total of three replicates for each soil types were done from the nine transects for each location. A total of 41 species from five subfamilies (i.e. Coptotermitinae, Rhinotermitinae, Termitinae, Macrotermitinae and Nasutitemitinae) and two families (i.e. Rhinotermitidae and Termitidae) of termite species were successfully sampled and recorded. Sand soil (81 colonies: 12 species; four subfamilies; two families) recorded the highest colonies, followed by peat soil (62 colonies: 12 species; five subfamilies; two families), and clay soil (47 colonies consisting; nine species, four subfamilies and two families). There was a significant difference (?2 = 618 886, df = 328, p<0.005) between soil types and termite species composition that were found in the oil palm plantation. This study identified that the diversity and abundance of termites differed between soil types in different oil palm plantations.

The activities and abundance of termites are highly affected by the environment. The objective of this study is to determine the activity of termites according to the different time of sampling event namely morning and evening session. The belt transects (100 metre length x 4 metre width) was set up in a line across the oil palm plantation. The sampling time was divided to the morning session (8:00 am to12:00 pm) and the evening session (2.00 pm to 6.00 pm). The presence of termites at each sampling time was recorded. A total of 12 belt transects with six replications for each sampling time at four different localities (MyFKT, MyLSK, IdFRGB, and IdCPSK) were placed. The results showed that the morning session recorded more species(31 species) in comparison to the evening session (15 species), and there are significant differences between the two sessions (?2=45,119, df=30, p<0.05). Based on the autocorrelation, there are also significant differences on the termite�s activities between the two session. Overall, the termite activity is more active in the morning. The effect on the environment such as temperature and humidity in the morning and midday affect the abundance, diversity, and the presence of termites. � 2017, Centre for Insects Systematic, Universiti Kebangsaan Malaysia.

Termite survey was conducted at six oil palm agroecosystem sites in Riau Province, Sumatra, Indonesia to document species richness across the sites. Six sites were surveyed by using continuous transect representing gradients of oil palm landuse across Indragiri Hulu to Bengkalis District since February 5th, 2015 until May 21st, 2015. Termites were sampled by modified transect protocols (100 m � 4 m � 10 cm). A total of 23 species belonging to two families and five subfamilies were collected. The termite assemblage was dominated by wood-feeding termites. The major family collected was Rhinotermitidae which included some pest species, such as Coptotermes curvignathus, C. sepangensis, C. kalshoveni, Schedorhinotermes malaccensis, S. medioobscurus, S. brevialatus, and S. javanicus. � 2016 Author(s).

Termites are found in various habitats, particularly diverse communities occurring in tropical forest and peatlands. Termites are beneficial insects, which function as soil engineers, improving the soil quality. However, in peatlands converted to commercial oil palm plantations, they are considered as pests. There is lack of studies on termite communities in converted peatlands in Peninsular Malaysia. Thus, this study investigated termite species associated with oil palm stands in three soil types (clay, shallow peat and deep peat) in Endau Rompin Plantation. The stand scouting method was used to record the numbers and types of termites associated with palm trees in the individual stands on different soil types. A total of 29 termite species associated with the palm stands were identified morphologically. All the species belonged to the families Rhinotermitidae and Termitidae. Twenty-three of the 29 species were found in the shallow peat, 16 in clay soil and 15 in deep peat. The community structure was synthesized by two-way cluster analysis with Sorensen (Bray Curtis) distance measure. Five termite groups associated with two soil types (clay soil and shallow/deep peat) were generated. Moisture levels and organic content were likely to determine the presence of soil feeders identified in the presence study. This study provides information on the status of termite species in oil palm plantation areas. Such information may be useful in future planning strategies by the plantation management.
