Abstract

ABSTRACT Pineapples are a fruit that grows on bushes with the scientific name Ananas comosus. They are native to Brazil (South America) and have been domesticated there since before Columbus’ advent. In the 16th century, Spaniards brought pineapples to the Philippines and the Malaysian Peninsula, then into Indonesia in the 17th century. This study aims to know the insects associated to monocultured and polycultured pineapples (A. comosus) and to know the dominant insects among said plants. This study is expected to inform about significant insects, both as pests as well as natural enemies, so it can be managed in pineapple planting systems and used in pineapple pest control. This study was done in the pineapple plantation village of Lobong and Mongkunai, regency of BolaangMongondow. Laboratory observations were done in the Weeds and Entomology laboratory of the Agriculture Faculty, University of Sam Ratulangi. Observation of insects on plant pineapples were calculated using the trap sinks. Insect observations showed that there are 6 insect orders founded to monocultured and polycultured pineapple plants, namely: Coleoptera Orders, Orthoptera Orders, Diptera Orders, Hymenoptera Orders, Collembola Orders and Lepidoptera Orders. Dominant insects in the monocultured and polycultured pineapple plantations are firstly from the Hymenoptera Order (Family of Formicidae), next from the Orthoptera Order (Family of Acrididae), third from the Coleoptera Order (Family of Scolytidae) and fourth from the Diptera Order (Familiy of Drosophilidae). Key words : Pineapple Plant (Ananas comosus), Inventory of insects, Monocultured And Polycultured.

Abstract

ABSTRACKCabbage (Brassica oleracea var. Capitata L. f. alba DC) is a vegetable that contains vitamins, minerals, proteins, carbohydrates and grese for the formation of human body and increase energy for the activity of human muscles. North Sulawesi is a region that has a large planting vegetables in the east of Indonesia. Cabbage crop harvested area of approximately 1,614 ha, with an average production of 17.25 tonnes per ha. The low production of cabbage in North Sulawesi caused by farming system which is still conventional and the presence of pests especially Plutella xylostella and Crocidolomia binotalis. The study aims to determine the percentage of the population and parasitization of the parasitoid Diadegma semiclausum in District Modoinding. The experiment was conducted in the South Minahasa Modoinding. Implementation of the study lasted for six months, start from July to December 2013, the research using survey method conducted on cabbage and other Brassicaceae plant at Modoinding District of South Minahasa Regency. Criteria for the location of the sample is the presence or type of cabbage and other Brassicaceae. Materials and tools used in this research are larvae and pupae of Plutella xylostella, Brassicaceae plants, sample bottles, bottle collection of 70% alcohol, tweezers, scissors, cutter, aqua glass, asahi cloth, rubber bands, "hand counter" and "loupe" , as well a stationery. The observation of parasitoid parasitization highest percentage found in the village of Lineleyan which reached 25.23%, then the Kakenturan Village respectively 17.40%, 1.83% Pelelon, Sinisir 1.05%, 0.93% and Mokobang Wulurmaatus 0.59%. Results sweeping using insect nets on cabbage and other Brasicaceae found that the highest population in the village of D. semiclausum Lineleyan (25, 42 individuals), and then successively Kakenturan Village (19.08 individuals), Palelon village (4.75 individuals), Sinisir village (4.50 individuals), Wulurmaatus village (4.08 individuals), and the Mokobang village (2.66 individuals).Keywords: Plant cabbage,Plutella xylostella and Diadegma semiclausum
