Abstract

The analysis of efficacy of clove oil (Syzigium aromaticum), ginger oil (Zingiber officinale), and nutmeg oil (Myristica fragrans) to hairy caterpillar was conducted. The hairy caterpillar were reported to attack some plants in 2010 to 2011 in Indonesia .To control the caterpillar, recently, peoples used chemical insecticide, however the impact of chemicals insecticide is dangerous to human being, livestock, and environmental. Therefore to minimizing those problems, the control methods should be environmental-friendly and safe against human being. One of those methods is utilizing the botanical pesticide which is extracted from tropical plants. Therefore efficacy of essential oils was done in order to find out the method to control population of it with environmental friendly approach. The experiment result shown at the concentration 10%, all of the essential oils are effective to kill the caterpillar (90-100%). Therefore the examinations of low concentrations of essential oils were conducted (5, 2, and 1%). The result of 1% concentration of ginger oil, nutmeg oil and clove oil are 80 %, 76 % and 68 % respectively.

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

The Fruit Flies Species (Bactrocera spp.) attacking Citrus Orchard in Gianyar and Bangli Regency of Bali Field research on species composition and attacks of fruit flies was done on citrus orchard located in Gianyar and Bangli Regency of Bali from May up to August 2016. The research aimed to identify and analyze of species composition and attacks of fruit flies attacking the fruit in the field. The research using survey method by collecting of attacked-fruits, purposively on citrus orchard in the field. Adults of fruit flies were identified by identification key of Drew and Hancock (1994). The results indicated that there were two species found on the citrus orchard namely Bactrocera carambolae and Bactrocera papayae The composition of both species were 61 % for B. carambolae and 39 % for B. papayae. B. carambolae was dominant at an altitude of 850 meters above sea level (61.29 % ; 19 adults), 1100 meters above sea level (62.22 % ; 84 adults) and 1200 meters above sea level (68.67%; 57 adults), while B. papayae was dominant at an altitude of 750 meters above sea level (59.32 % ; 35 adults). B. carambolae was also dominant on the variety of Siam, Keprok Selayar and Keprok Batu 55. The affecting factors on the population abundance of fruit fly were affected by the length of cultivation and the number of citrus plant population in each elevation. The average number of adults emerged from an orange fruit was 3 adults while the highest appearance was 11 adults. The highest percentage of fruit flies attacked was at the five months and two week ages of the fruit as much as 7.18 %.
