A preliminary study to determine the diversity, abundance and species similarity of ichneumonid wasps in three different altitudes (150-200m, 700-800 m and 1000–1100 m above sea level) of Gunung Jerai, was conducted from 2nd to 7th June 2005. This study had successfully collected and recorded 32 inchneumonid individuals from 21 species, 16 genera and six subfamilies (Cryptinae, Metopiinae, Campopleginae, Banchinae, Pimplinae and Ophininae). The cryptine had the most number of individuals (15), genera (8) and species (9). However, the most dominant genus was Leptobatopsis (Banchinae) by having six individuals. The genera Leptobatopsis and Friona seemed to be specialized and adapted in higher altitude of Gunung Jerai (1000-1100 m asl). The number of ichneumonid individuals was significantly (p < 0.05) higher in altitude of 1000-1100 than the other two lower altitudes. Of 16 genera recorded, seven (Sulcarius, Palpostilpus, Caenopimpla, Acerataspis, Eriborus, Sinophorus and Rhachoaplex) were new records for Malaysia. Interestingly, the genus Sulcarius was recorded for the first time in the Oriental and Australian Regions. In contrast to individual abundance, the diversity of Ichneumonid wasps was not significantly (p>0.05) different between altitudes 150- 200 m and 1000-1100 m. Although data from 700-800 altitude was not enough to be statistically analyzed, the abundance of individuals between the lower two altitudes was also not significant. Result of cluster analysis showed two groups (clusters) exist and that the group-1 was the lower two altitudes of Gunung Jerai sharing 65.7% ichneumonid wasps species while the group-2 was the upper most altitude (1000– 1100 m) that have only 49.2% species similar to that of group-1. Comparison of ichneumonid wasps diversity between Gunung Jerai with other forests in Malaysia is also discussed.

Abstract

A preliminary study to determine the diversity, abundance and species similarity of ichneumonid wasps in three different altitudes (150-200m, 700-800 m and 1000–1100 m above sea level) of Gunung Jerai, was conducted from 2nd to 7th June 2005. This study had successfully collected and recorded 32 inchneumonid individuals from 21 species, 16 genera and six subfamilies (Cryptinae, Metopiinae, Campopleginae, Banchinae, Pimplinae and Ophininae). The cryptine had the most number of individuals (15), genera (8) and species (9). However, the most dominant genus was Leptobatopsis (Banchinae) by having six individuals. The genera Leptobatopsis and Friona seemed to be specialized and adapted in higher altitude of Gunung Jerai (1000-1100 m asl). The number of ichneumonid individuals was significantly (p < 0.05) higher in altitude of 1000-1100 than the other two lower altitudes. Of 16 genera recorded, seven (Sulcarius, Palpostilpus, Caenopimpla, Acerataspis, Eriborus, Sinophorus and Rhachoaplex) were new records for Malaysia. Interestingly, the genus Sulcarius was recorded for the first time in the Oriental and Australian Regions. In contrast to individual abundance, the diversity of Ichneumonid wasps was not significantly (p>0.05) different between altitudes 150- 200 m and 1000-1100 m. Although data from 700-800 altitude was not enough to be statistically analyzed, the abundance of individuals between the lower two altitudes was also not significant. Result of cluster analysis showed two groups (clusters) exist and that the group-1 was the lower two altitudes of Gunung Jerai sharing 65.7% ichneumonid wasps species while the group-2 was the upper most altitude (1000– 1100 m) that have only 49.2% species similar to that of group-1. Comparison of ichneumonid wasps diversity between Gunung Jerai with other forests in Malaysia is also discussed.
