Abstract

This study was aimed to investigate the population dynamics of the cabbage insect pests, Plutella xylostella and Crocidolomia pavonana under natural conditions. The population succession patterns of both pests were determined by observing the abundance of their population on a regular basis from the beginning to the end of the planting season. Understanding the population succession patterns of P. xylostella and C. pavonana will give an idea the shifting time by both pests on attacking the crops, therefore on deciding the time of controlling. The population succession patterns occur in 8 weeks of planting season. P. xylostella dominated the cabbage plants when they were 1-5 weeks after planting (WAP), but when the cabbage plants were more than 5 weeks old they were dominated by C pavonana.

Abstract

The Influence of Fipronil 50 g/l Against Population Abundance and Parasitization Level of Egg Parasitoid of Yellow Rice Stem Borer in Tabanan District Yellow rice stem borer, Scirpophaga incertulas Walker (Lepidoptera: Pyralidae), is one of the important pests of rice plants in Indonesia. Efforts to control those pests are using a lot of synthetic insecticide in the field, meanwhile egg parasitoid is considered to have an important role in the control those pests in nature. The aim of this research is to know the influence of insecticide with active ingredient Fipronil 50 g/l to population abundance and parasitization level of egg parasitoid of yellow rice stem borer. The research was arranged by using randomized block desing with six treatments and four replicates. The results showed that T. Schoenobii parasitoid is the most dominant parasitoid among other types of parasitoids and its diversity is low that is <1,5. Pesticide with active ingredient Fipronil 50 g/l has significant effect on population abundance and parasitization level egg parasitoid of yellow rice stem borer. The highest population abundance was on control and lowest in treatment dose 1.50 cc/l. The highest parasitoid parasitization rate in Tabanan is (19.70%). The parasitization rate was decrease with the increase of tested insecticide dose, so the lowest number was at 1.50 cc/l treatment with percentage (8.62%).

Abstract

The Diversity and Abundance of Egg Parasitoids Population that Associated with YellowRice Stem Borer on Rice Crop in Tabanan Regency. Rice stem borer is an important pest in rice plants that are real may cause decrease in result. Control of the rice stem borer in Tabanan still relies on the use of synthetic insecticides. This way is not effective. To overcome the problem it, necessary the efforts to integrated pest management. Biological control using the egg parasitoid rated as excellent because parasite as eggs of pests, so that pests do not develop into larvae (phases that damage crops). This research conducted in the sub district of Kediri which has a height (350 m asl) and in the sub district Baturiti which has a height (600 m asl) by using the survey method. The result showed that diversity of the population of parasitoid eggs rice stem borer yellow in both height appertain is low with diversity index <1.5. There are three species of parasitoid eggs found scilicet T. schoenobii, T. rowani T. japonicum with similarity index of 100% in the second location. Population abundance egg parasitoid in altitude (350 meters asl) highest is indicated by T. rowani and the lowest is shown by T. japonicum, while at altitude (600 m asl) highest is indicated by T.schoenobii and lowest shown T. japonicum. The level of parasitism parasitoid eggs have in common in both height. The highest level parasitism on the vegetative phase shown by T. schoenobii and on generative phase shown by T. rowani.
