| Summary: | This study was carried out to investigate diversity and provide current species checklist of mantis in Sabah. To date, this is the first study of mantis in Sabah that is conducted on a long-term basis. This study was carried out in Lower Kinabatangan where two study sites were used which was Sukau Village (SV) and Gomantong Virgin Jungle Reserve (G.VJR); and Danum Valley Conservation Area (DVCA). Six samplings have been conducted (August 2008-June 2009) which consisted of 20 days sampling respectively at each study site. Mantises were sampled using light-trap and manual collection techniques. Additional method, baited trap was carried out for one week in DVCA to test the effectiveness of the method to sample mantises. In this study, a total of 40 species (824 individuals) belonging to seven families were collected. This result represented approximately 39% out of 102 species of mantises that were recorded in Borneo. The dominant family was Mantidae. A total of four families representing 11 species with 7S individuals were recorded from SV (disturbed area, D/R); this followed by 15 species with 143 individuals belonging to five families in G.VJR (Class VI protected area, P-VI) and seven families which included 35 species with 606 individuals were recorded from DVCA (Class I protected area, P-I). These sampling sites shared three species (8%) with 288 individuals (28%). Glldella suavis was sampled only using baited trap. Most of the mantises were sampled during night time (809 individuals, 98%) and using light-trap (700 individuals, 85%). The most dominant species was Hierodula sp. 1 making up 17% (139 individuals) of total mantises collected and eight singletons were sampled. There were two unidentified species and indicated as sp. 1 and sp. 2. A total of 21 species from six families were new records for Sabah. The Shannon-Wiener diversity index, H' was higher in P-I compared to the two other study sites (D/R=1.91, P-VI=2.1, P-I=2.72). Similarly result for Margalefs diversity index, ~ and Simpson's index, 1/ D. The diversity indices were compared between sampling sites using 95% bootstrap confidence limits and showed the same result for H; Dмg and 1/D. Pairwise comparisons using randomization tests for H;Dмg and 1/D showed that there were significant different (p<0.05) in species diversity between D/R & P-I and P-VI & P-I; not significant different (p>0.05) between D/R & P-VI. Overall, light-trap was the most effective method compared to manual collection and baited trap. Apart from gathering information on diversity, data collection on life history, behaviour and ecology were also included in this study. For life history, different stages of mantis were observed. For mantis's behaviour, defensive strategy and mating activity of Amantis reticulate were observed. For their ecology, oothecae attacked by ants and fungus infection were observed. Specimen identification was the major problem of this study due to lack of literature on key for identification of mantises. |
