Efficacy of 18 g / l Abamectin Insecticide Against Species Diversity, Population Abundance of leafhoppers and Harvesting on Paddy Paddy Crops (Oryza sativa L.) This research was carried out in Buwit Village, Kediri District, Tabanan Regency, starting in September to November 2017. The research objective was to determine the effect of Abamectin insecticide 18 g/l on species diversity, population abundance and yield. This study used a randomized block design (RBD) with 5 replications and 5 treatments (control, 0.50g / l; 1.00g / l; 1.50g / l; 2.00g / l). The results showed that leaf leafhopper species diversity was low, as evidenced by the Shanon diversity index value was <1.5. The low value of species diversity index is caused by the low number of species in each treatment. Relatively higher variation in control compared to treatment. Abundance The highest population of nymphs and leaf leafhoppers was seen at 49 days after planting as much as 8.57. Components of harvest also show a significant difference between control and treatment.

ABSTRACT Efficacy of Essential Oil of Lemongrass (Cymbopogon citratus L.) to Diamond Back Moth (Plutella xylostella L.) on Cabbage in the Laboratory The use of synthetic pesticides continuously will be affect the biotic and non-biotic factors. Therefore, the others control measure which were practically, effectively and safely to human being and environmental - frendly must be created. Geographic condition of Indonesian has been known is rich in biodiversity is necessary to be studied to find the sources for pest control measure which is environmental-friendly. Study about “ Efficacy of Essential oil of Lemongrass (Cymbopogon citratus L.) to Diamond Back Moth (Plutella xylostella L.) on Cabbage was conducted in February, 4. to October, 18.2012 in the Laboratory of Pest and Diseases, Departement of Agroekotechnology, Faculty of Agriculture, Udayana University. The purpose of this study is to determine killing capacity of essential oil of Lemongrass (C. citratus) against Diamond Back Moth (P. xylostella) on Cabbage. The results showed that the essential oil of Lemongrass is effective to kill the larvae of DBM (P. xylostella). The level of concentrations that is used as treatment in this study are 1.5%, 1.25%, 1.%, 0.75%, and 0.5% that have a significant effect to kill the larvae of P. xylostella compare to the control treatment (tween 80 and water). Concretation 0.5% of lemongrass oil causing mortality in average 38.67%, while the concentrations 1.5% is 100%. The concretations 1.25%, 1%, and 0.75% their percentage of mortality are 94.67%, 74.67%, and 56%, respectively. Base on the results of this study, the optimum concretation which are give mortality to the larvae is 1,5% with the percentage of mortality reach to 100% on 6 days after treatment. Key words: Efficacy, Lemongrass (Cymbopogon citratus), Diamond Back Moth (Plutella xylostella)

ABSTRACT The Diversity and Density of the Population Parasitoid who Associated with Plutella xylostella L. (Lepidoptera: Plutellidae) on Plantation Plants without and with Insecticide Application The research was conducted at the Laboratory of Integrated Pest and Disease Management, Concentration of Plant Protection, Department of Agroecotechnology, Faculty of Agriculture Udayana University. The purpose of this research to find out diversity and density of parasitoids population associated with Plutella xylostella on cabbage plantation without and with insecticide application. Sample was taken by using diagonal sampling. There are nine points sample on cabbage plantation without and with insecticide application and each point content 18 plants. The sample was taken every weeks, while application insecticide was done every 10 days. Data was analyzed by using T-test. The result of the research indicated that there is one parasitoid was found associated with P. xylostella on cabbage plantation without and with insecticide application. That parasitoid is Diadegma semiclausum. Population of P. xylostella and D. semiclausum not significant difference on cabbage plantation without and with insecticide application, and so it seems of parasitization rate of parasitoid. Keywords: insecticide, Plutella xylostella, parasitoid, cabbage

The study was conducted since October 2018 up to March 2019 by using purposive method to take mangoes attacked by fruit flies in Buleleng Regency. The results showed that three were species of fruit flies that attacked mangoes in Buleleng Regency, that are B. papayae, B. carambolae and B. occipitalis. Population density of B. papayae was higher than density population of B. carambolae and B. occipitalis. Average population density of B. papayae, B. carambolae and B. occipitalis were 9,36 adult/fruit, 5.15 adult/fruit and 0,04 adult/fruit, respectively. Type similarity index has a range of values from 80 – 100% with population distribution randomly (S2/X = 1) at each study location.

Morphological Characteristics and Populations Abundance of Parasitoid (Hymenoptera) on Invasive Pests Cassava Mealybug, Phenacoccus manihoti Matile-Fererro (Hemiptera: Pseudococcidae) in Bali. This study aims to know the morphological characteristics of parasitoid, population abundance and distribution patterns of parasitoid associated with P. manihoti on cassava crop in Bali. The study was conducted on all cassava crop in Bali with a field observation method that was determined by taking shoots of cassava plants attacked by cassava mealybug P. manihoti, then cassava mealybug P. manihoti were nurtured, then observation was carried out every day until parasitoid appeared and being identified. The results of the study showed that there were three dominant types of parsitoid that were found to be associated with invasive pest P. manihoti, namely Anagyrus lopezi, Acerophagus papayae and Blepyrus insularis. The abundance of parasitoid populations was dominated by parasitoid A. lopezi with a range of values 48.6–81.8%. Then followed by parasitoid A. papayae 7.7 - 37.1%, and B. insularis 3.4 - 14.3%. The distribution pattern of parasitoid varies in each species, parasitoid A. lopezi spreads in groups categories, Parasitoid A. papayae and B. insularis spread random-regulary on cassava crop throughout on each of the Regencies in Bali.

Population Abundance and Parasitization Level of Indigenous Parasites to Invasive Liriomyza trifolii (Burgess) (Diptera: Agromyzidae) on Asteraceae Plants in Bali. This study was aimed to determine the population abundance and parasitization level of indigenous parasitoid associated with Liriomyza trifolii (Burgess) in Asteraceae plants in Bali. The study was conducted from January to March 2019 by survey method on the type of parasitoid, abundance and parasitisation level in Asteraceae plants which included to Chrysanthemum, Gerbera jamesonii and Helianthus annuus, which are spread in several regencies in Bali such as Buleleng (1200 m asl), Bangli (900-1000 m asl) and Denpasar (40 m asl). Sampling was done purposively on the leaves of plants attacked by Liriomyza sp. and then maintained at the Laboratory until the parasitoid adults appeared. Afterward, morphologically was identified the type of parasitoid that appears. The results showed that there were three types of indigenous parasitoid associated with L. trifolii namely Hemiptarsenus varicornis, Neochrysocharis okazakii, and Opiusdissitus. The most dominant parasitoid of the three types of H. varicornis parasitoid with an abundance of 78.57% and parasitization rate of 53.23% was found in Chrysanthemum plants.

The Effect of Feed (Onion Leaves) on the Event of Color Polymorphism on Larvae Spodoptera exigua HUBNER (Lepidoptera: Noctuidae). Color polymorphism is a form of color difference that appears morphologically and genetically in the same insect species. The existence of these changes in shape has to do with the defense mechanism of the species concerned for disguise, avoiding natural enemies and adjusting to the new environment. The occurrence of color polymorphism is often found in S. exigua larvae that attack the onion crop in the field. The purpose of the study was to determine the effect of the quality and quantity of feed (onion) on the color changes of S. exigua larvae. This research was carried out in the laboratory using adaptation test method and comparative test with randomized block design. The results of the study show that decreasing the quality and quantity of feed (onion) encourages color changes from green to dark. In addition, green to dark color changes are also triggered by the developmental phase of the larvae. The development of larvae from the 3rd instar phase has shown symptoms of color change from green to dark even though the quantity and quality of the food is fulfilled.
