Abstract

Implications of the Existance of Invasive Species-Waterhyacinth on Communities of Parasitoid InsectABSTRACT. The introduction of an invasive exotic plant species may influence parasitoid insect community indirectly. The objective of this research is to evaluate the implication of the existence of invasive species-waterhyacinth on parasitoid insect community. The research was done in several fresh water ecosystem occupied by waterhyacinth in west java and DKI Jakarta, conducted during January 2004 to March 2006. Sweep net and yellow pan trap were use to collect the sample of insects. The result of the research showed that the existence of waterhyacinth may indirectly resulted in decreasing species richness and diversity of parasitoid insect. The observation also showed that the existence of waterhyacinth may lead to homogenization of parasitoid insect in aquatic vegetation.

Abstract

The Introduction of Neochetina eichhorniae (COLEOPTERA: CURCULIONIDAE): The Potency of Non-Target Impact on Local Plant CommunitiesABSTRACT. When introduce an exotic insect species as a biological agent thought cause non-target impacts, directly or indirectly, on local plants species. The objective of this research is to evaluate the potency of nontarget impacts of introducing Neochetina eichhorniae on local plants aquatic communities. The results of the research indicated that the weevil showed a high preference and host specific on waterhyacinth, and so far the house shifting was not occur. Insitu observation showed that this biological agent was not found in any others aquatic and non aquatic plants living around water areas. This data indicated that host range expansion by the weevil was not consist.

Abstract

Composition and Community Structure Hymenoptera Parasitoid Garden Maintained by Conventional and Organic Coffee In District Aceh TengahABSTRACT. This study aimed to obtain scientific information about the species or group of parasitoids associated with habitat, so as to build a database for the purposes of pest management in the future. This research was conducted in coffee plantations in Central Aceh District and continued identification in Pest Laboratory, Faculty of Agriculture UNSYIAH from June to November 2014. This study used a survey method. Insect sampling done by purposive sampling method on coffee plantations were managed conventionally and organically. Abundance of individuals, the number of families and species richness highest Hymenoptera encountered in the practice of organic farming over conventional coffee. Hymenoptera parasitoids composition of coffee plantations are managed organically composed of 13 families, while the coffee plantations were managed conventionally only 7 families. However, Hymenoptera parasitoid community structure on both habitat types are relatively the same because it is dominated by the families Braconidae and Ichneumonidae.
