Abstract. Ikhsan Z, Hidrayani, Yaherwandi, Hamid H. 2020. The diversity and abundance of Hymenoptera insects on tidal swamp rice field in Indragiri Hilir District, Indonesia. Biodiversitas 21: 1020-1026. Hymenoptera is one of the four largest insect orders and it plays a vital role in human life as pollinators, parasitoids, and predators. Hymenoptera parasitoids are particularly important as agents of biological control of pest. The objective of this research was to study the diversity and abundance of Hymenoptera on tidal swamp rice field in Indragiri Hilir District, Riau Province, Indonesia. Samplings were conducted in 3 sub-districts of rice production centers, namely Batang Tuaka, Keritang and Reteh, using four trapping techniques (i.e. insect net, malaise trap, pitfall trap, and yellow pan trap). Shannon diversity index (H '), Krebs evenness index (E), and Jaccard similarity index (Is) were calculated. We found 4,701 individuals consisting of 39 families and 319 species of Hymenoptera at the three studied areas. Tidal swamp rice in Indragiri Hilir District had a high species diversity of Hymenoptera parasitoids and Hymenoptera predators, but a moderate species diversity of Hymenoptera pollinators. Species diversity and evenness of Hymenoptera parasitoids and predators were higher in Keritang than in Batang Tuaka and Reteh. The families of Formicidae, Braconidae, Ichneumonidae, and Scelionidae had the highest number of species, while Formicidae, Scelionidae, Diapriidae, and Braconidae had the highest number of individuals. Based on these findings, the abundance and diversity of Hymenoptera insects in Indragiri Hilir District have the potentials to be developed as biological agents to control pests on tidal swamp rice in this area.

Abstract. Taniwel D, Leiwakabessy F, Rumahlatu D. 2020. Short Communication: Density and length-weight relationship of mudskipper (Periophthalmus spp.) in the mangrove area of Kairatu Beach, Maluku, Indonesia. Biodiversitas 21: 5465-5473. Mudskippers (genus Periophthalmus) fish species inhabit mudflat, sandy beaches, and mangrove areas. Their daily activities are influenced by tidal rhythms. The aim of this research was to identify the species of mudskipper, their density, and length-weight relationship of more density species in the mangrove area of ​​Kairatu beach, Maluku, Indonesia. This research was conducted from July to August 2018, 3 sampling sites using purposive sampling technique. The physical-chemical parameters of environmental conditions (temperature, dissolved oxygen, salinity, and pH of water) were measured directly on location (in-situ), while the different mudskippers species present in the study sites were identified in the laboratory at the Pattimura University. Quantitative data on population density and length and weight of individuals were obtained for four Periophthalmus species. The physical-chemical parameters of environmental conditions in the three sampling stations were within the range of optimal values previously obtained for mudskipper species. The temperatures ranged from 30.01-30.05 oC, the dissolved oxygen ranged from 7.1-7.5 mg/L, the pH ranged from 7.3-7.5, and the salinity ranged from 5-7 ‰. The four mudskippers species identified in the sampling sites were (in density descending order): Periophthalmus argentilineatus (5.05 ind/m2), P. gracilis (1.5 ind/m2), P. malaccensis (0.4 ind/m2) and P. kalolo (0.3 ind/m2). The results of the regression analysis showed that there was no significant relationship between physical-chemical parameters to mudskipper density. The results of the length-weight relationship of the two most abundant species P. argentilineatus and P. gracilis a negative allometric length-weight relationship (b<3), while the P. kalolo and P. malaccensis indicated a positive allometric growth type (b>3).
