Diversity of fireflies (Coleoptera : Lampyridae) of Sungai Teratak Sabah Malaysia

Foo Kevin, . and Mohamed Dawood Mahadimenakbar, . Diversity of fireflies (Coleoptera : Lampyridae) of Sungai Teratak Sabah Malaysia. pp. 1-11. ISSN 1823-3902

This study was conducted to investigate the diversity and possible factors that structure the distribution and abundance of fireflies along Sungai Teratak. Six sampling occasions were conducted from March to April 2014 where ten display trees were chosen as sampling stations. Species abundance and composition of fireflies and other insects were assessed by visual assessment and sampling with aerial net. Four Pteroptyx species were discovered with difference in relative abundance namely Pteroptyx bearni (93.1 ) Pteroptyx valida (2.2 ) Pteroptyx malaccae (3.9 ) and Pteroptyx tener (0.8 ). The results of Shannon-Weiner index H was 0.316 and Simpsons index of diversity with the value of 0.131 indicated that the firefly at Sungai Teratak was low in diversity. Abundance of fireflies varied significantly between the six sampling occasions (Kruskal-Wallis � 15.382 d.f.5 p0.05) but shows no difference in abundance between the ten display trees (Kruskal-Wallis �14.181 d.f.9 p0.05). The abundance of fireflies was found to be positively correlated to the abundance of other insects (Pearsons correlation r0.740 p0.05). Comparison of fireflies abundance during full moon and new moon nights showed no significant difference (Mann-Whitney U 46.00 z-0.326 p0.05 and Mann-Whitney U25.50 z-1.945 p0.05). Although the abundance of male (n232) fireflies outnumbered the female (n149) statistical analysis proved no significant difference between both groups (Mann-Whitney U 8.50 z-1.529 p0.05). The mangrove trees being colonized by fireflies at Sungai Teratak was mainly from the species Avicennia alba.

Abstract

This study was conducted to investigate the diversity and possible factors that structure the distribution and abundance of fireflies along Sungai Teratak. Six sampling occasions were conducted from March to April 2014 where ten display trees were chosen as sampling stations. Species abundance and composition of fireflies and other insects were assessed by visual assessment and sampling with aerial net. Four Pteroptyx species were discovered with difference in relative abundance namely Pteroptyx bearni (93.1 ) Pteroptyx valida (2.2 ) Pteroptyx malaccae (3.9 ) and Pteroptyx tener (0.8 ). The results of Shannon-Weiner index H was 0.316 and Simpsons index of diversity with the value of 0.131 indicated that the firefly at Sungai Teratak was low in diversity. Abundance of fireflies varied significantly between the six sampling occasions (Kruskal-Wallis � 15.382 d.f.5 p0.05) but shows no difference in abundance between the ten display trees (Kruskal-Wallis �14.181 d.f.9 p0.05). The abundance of fireflies was found to be positively correlated to the abundance of other insects (Pearsons correlation r0.740 p0.05). Comparison of fireflies abundance during full moon and new moon nights showed no significant difference (Mann-Whitney U 46.00 z-0.326 p0.05 and Mann-Whitney U25.50 z-1.945 p0.05). Although the abundance of male (n232) fireflies outnumbered the female (n149) statistical analysis proved no significant difference between both groups (Mann-Whitney U 8.50 z-1.529 p0.05). The mangrove trees being colonized by fireflies at Sungai Teratak was mainly from the species Avicennia alba.
