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.

The recognition of intraspecific variation could enhance knowledge and understanding on the population divergence that might be resulted from different geographical areas. To study the possible effect derived from different locations, a morphometric study of the red stripe weevils, Rhynchophorus vulneratus from different localities in Malaysia was conducted using field and voucher specimens. A total of twenty-Three morphological characters were examined from 108 individuals of R. vulneratus representing population of Kota Samarahan, Mukah and central of Peninsular Malaysia. The data were subjected to univariate one-way single factor analysis of variance (ANOVA) and analysed in factor analysis using SPSS version 22.0 software. Univariate ANOVA showed that all tested variables were significantly different (p<0.05) except for mesocoxal distance (MSD), meanwhile from the factor analysis, the first three factors with eigenvalues greater than 1.0 were successfully extracted, resulting in a high variation of 82.687%. For factor 1, 39.213% of total variation was recorded, factor 2 accounted for 34.096% and factor 3 contributing to 9.377%, respectively. The mixed plotting among the twenty-Three morphological characters suggests a strong correlation among the parameters examined and further statistical analysis should be conducted to include environmental factors such as habitat types, food availability and predation effect. � 2018 Author(s).

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).
