The research was conducted to determine the diversity of species and the role of insects between pests and natural enemies insect in siamese orange (Citrus nobilis l.). Observation was done in Karangsari villege, Karangpawitan subdistrick, Garut districk from April to Jone 2018. The method used in qualitative method in five different land basedon the age of siamese orange plants (Citrus nobilis l.) where on the first and seccond field of the plant age 1,5 years, the third land the plant age of 2,5 years, the fourth land the age of the plant 4 years, and on the fifth is the age of 8 months of plant life which concists of 2 observation, that is observation using yellow trap and visual observation at 5 sample points of siamese orange (Citrus nobilis l.). The results showed that the insects found in citrus (Citrus nobilis l.) plants consisted of 9 orders and conculated using the diversity index and dominance index. Insects found from five different fields, generally insect pests are the highest compared to natural enemies. The highest insects populations is on experiental land 5 with 8 moths of plant life and diversity index on five fields of siamese orange (Citrus nobilis l.) planting has a moderate measure value and a low dominance index.
研究了连体橙(Citrus nobilis l.)害虫和天敌之间昆虫的种类多样性和作用。于2018年4月至6月在加鲁特县Karangpawitan街道Karangsari村进行了观察。定性方法中使用的方法在五个不同的土地在暹罗的时代橙色植物(柑橘nobilis l。)在第一次和seccond植物领域1岁5年,第三个陆地植物2岁,5年,第四土地植物4年的年龄,和第五是8个月的时代的植物concists 2的观察,观察使用黄色陷阱和视觉观察5个采样点的暹罗橙色(柑橘nobilis l。)。结果表明，柑橘(citrus nobilis l.)植物中发现的昆虫共有9目，采用多样性指数和优势度指数进行计算。昆虫分布在五个不同的领域，与天敌相比，通常害虫是最高的。昆虫种群数量最高的是试验地5，植物寿命为8个月，5块地种植暹罗柑的多样性指数测量值中等，优势度指数较低。
