Abstract

The Diversity and Abundance of Egg Parasitoid Population Rice Stem Borer in Tabanan Regency Rice is the staple food for most of the population of Indonesia. Tabanan Regency is a center production of rice in Bali Province. Judging from rice production in 2009 Tabanan Regency can produce 242 thousand tons of grain per year, but to improve production of rice in the field has many obstacles, one of them is rice stem borer pest. Rice stem borer can attack plants in the vegetative phase and the generative phase. It is necessary for the proper control measures, through the concept of integrated pest management that emphasizes biological control efforts that use natural enemies. Biological control by using egg parasitoid rated excellent because do not cause resistance and resurgence, organisms that are used to find the host, can multiply and spread, and control can be run by itself. Egg parasitoid of rice stem borer is an important factor that can regulate the population of rice stem borer pest abundance in the field. There were three types of rice stem borer egg parasitoids in Tabanan Regency are Trichogramma japonicum Ashm, Telenomus rowani Gahan, and Tetratichus schoenobii Ferr. Parasitoid of T. japonicum is dominant parasitoids and parasitization rate of this highest than the other parasitoids at each altitude. The diversity of rice stem borer egg parasitoid relatively low at <1.5. The highest population abundance indicated by T. japonicum ( 33.8 % ) at height <250 ( 0-250 ) masl ( meters above sea level ) and the lowest was in the height of T. rowani >500( 500-750 ) masl.

Abstract

Imature Development and Parasitization Behavior of Hemiptarsenus varicornis (Girault) (Hymenoptera: Eulophidae) as a Larval Ectoparasitoid of Liriomyza sativae (Blanchard) (Diptera: Agromyzidae). Liriomyza is one of the important pests that attacking vegetable plants in Indonesia. Parasitoid which is commonly associated with Liriomyza is Hemiptarsenus varicornis. The study was conducted at the Greenhouse of the Faculty of Agriculture, Udayana University and at the Integrated Pest Management Laboratory Faculty of Agriculture, Udayana University, Denpasar. The research starts from February to September 2018. The purpose of this study was to determine the development and parasitization behavior of the pre-adult phase of H. variconis on L. sativae. The development of the parasitoid pre-adult phase was observed in the form of egg, larvae, pupa and imago stages. Observation of pre-adult phase parasitization behavior was carried out by tearing the leaves of plants that had been infested and observed under a binocular microscope. The result indicated that the time required for the development of pre-adult phase H.varicornis was nine days at an average temperature of 28oC, with egg stage (24 hours), larval stage (48 hours) and the pupa stage (120 hours). The parasitization behavior of the immature parasitoid H. varicornis includes three stages, namely the search for hosts, finding the host and receiving the host and directly infusing the host's body fluids, then going away from the host's destroyed body. Host search behavior occurs when new larvae appear, while the process of sucking in body fluids occurs when the instar-1 larvae before the instar-2 and away from the host occur before parasitoid larvae enter the pupa phase.

Abstract

Response of Braconid Parasitoid Against Invasive Pest, Liriomyza trifolii (Burgess) (Diptera: Agromyzidae) on Vegetable and Ornamental Crops in Bali. Research on the respopnse of Braconid parasitoids to the invasive pest, Liriomyza trifolii that attacks ornamental plants and vegetables in Bali, was carried out from September 2020 to March 2021. This study aimed to determine the type and abundance of parasitoid populations that responded to Liriomyza trifolii on host plants in the field. In addition, this study also aims to evaluate the level of parasitization of each parasitoid against L. trifolii. This study used a purposive sampling method by taking leaf samples that showed active symptoms of Liriomyza larvae in the leaves of plants. The research focused on vegetables and ornamental plants cultivated in lowlands <500 meters above sea level (masl), mediumlands 500-1000 meters above sea level and highlands> 1000 meters above sea level. The results showed that there were two species of Braconid parasitoids that responded to Liriomyza trifolii in the field, namely Opius dissitus and Opius cromatomiyae. The relative abundance and degree of parasitization of the two parasitoids showed variation between host plant species and altitude. The relative abundance of O. dissituse was high in chrysanthemum (10.81%) at an altitude of >1000 masl and low in long beans (0.53%) at an altitude of <500 masl. The highest relative abundance of O. cromatomiyae was in marigold flowers (51.18%) at an altitude of <500 masl and the lowest was in chrysanthemum (44.83%) at an altitude of > 1000 masl. The highest level of parasitization of O. dissitus was found in pakcoy plants (50.00%) at an altitude of >1000 masl and the lowest was in mustard plants (6.06%) at an altitude of <500 masl. The highest level of parasitization of O. cromatomiyae was in celery (33.33%) at an altitude <500 masl and the lowest was in tomato plants (25.00%) at an altitude> 1000 masl. Both species of Braconid parasitoids have high potential as biological control agents for L. trifolii as indicated by their relative abundance and high levels of parasitization against these invasive pests.
