Abstract
Abstract Diversity of plants species in post harvest rice field ecosystem area tends to be higher compared to before harvest. Tortoise beetles can be a threat to plants species that exist in rice field ecosystem area. Serdang Menang Village has a fairly extensive rice field ecosystem area. An inventory of tortoise beetles in rice field ecosystem area, Serdang Menang Village will be very helpful in potential estimating of tortoise beetles to plants that exist in rice field ecosystem area, Serdang Menang Village. Determination of this sampling location was done randomly in post harvest rice field ecosystem area, Serdang Menang Village. The sampling method uses small insecting net and hand picking methods. Species of tortoise beetles found were 5 species ( Aspidomorpha miliaris , Cassida subreticulata , Cassida circumdata , Cassida sp., dan Doloyala sp.) of a total 3 genera. Cassida circumdata and Aspidomorpha miliaris is tortoise beetles species that easiest to be found in this rice field ecosystem area which indicates that population is more than any species of tortoise beetles found. Cassida circumdata and Aspidomorpha miliaris can be major threat in rice field ecosystem area compared any species of tortoise beetles that found because a population is estimated to be more.
Highlights
Tortoise beetles are insects included in the subfamily Cassidinae
Need to do an inventory of tortoise beetles in rice field ecosystem area to see its potential threat for plant species found in rice field ecosystem area in Serdang Menang Village, Sirah Pulau Padang Sub-district, Ogan Komering Ilir District
Based on inventory that haa been done in post harvest rice field ecosystem area, Serdang
Summary
Tortoise beetles are insects included in the subfamily Cassidinae. Tortoise beetles have a role in controlling certain plant populations. Population of these tortoise beetles can be controlled using biological agents Enoggera nassau, Neopolycystus insectifurax (Withers, 2014), Tetrastichus cassidus and Eucelatoriopsis dimmocki (Capinera, 2015). Need to do an inventory of tortoise beetles in rice field ecosystem area to see its potential threat for plant species found in rice field ecosystem area in Serdang Menang Village, Sirah Pulau Padang Sub-district, Ogan Komering Ilir District.
