Abstract

ABSTRACT Fruit flies is one of the important pests which attack fruits in Indonesia and very detrimental economicaly. The objective of this research was to determine mating behaviour of fruit flies Bactrocera sp., testing their response to attractants methyl eugenol and cue lure as well as identification  some species of fruit flies that attack belimbing, ketapang and paria fruits. The fruits samples which were affected by fruit flies were collected  from plantation at Lopana and Kapitu, South Minahasa. Imago was assessed  at laboratory of entomology,  Faculty of Agriculture. Result showed that mating time of these species was occured between 17.10 – 18.45. Sexual maturity of belimbing fruit flies was  10 -12 days. Whereas ketapang fruit flies and paria fruit flies were 10 – 14 days and 11 – 13 days respectively.  B. dorsalis complex was  attracted to methyl eugenol. While B. albistrigata and B. cucurbitaceae Coq.were attracted to cue lure. Keywords : fruit flies  Bactrocera sp. Belimbing, ketapang, paria fruits, methyl eugenol and cue lure

Abstract

An integrated pest control on vegetables crops in the fields,  is one of the control method to suppress the insect pest population , therefore farmer do not depend on the chemical controls that have negative effect both on the environment and human as well as animal.  The science and technology program for communities [IbM] aim to get a package of integrated pest control technology that is enviromentally friendly and it is derived from Indonesian microbial resources to support sustainable agriculture system .  To achieve  the goal, the program  implemented  through counseling, plot demonstration and field work.  These activities provided motivation  to farmers to be able to use biological agents combined with culture control to suppress population of insect pest and vegetables through the extension activities and the plot  demonstrations.  The IbM activity gave benefit to farmers by transfer knowledge through extension methods on how to get and use biopesticides with its theory and it can be directly practiced by farmers in the form of a plot demonstrations.

Abstract

Refugia is a plant used in plant cultivation that provides food in the form of nectar and honeydew needed by parasitoid imago so that it can survive its life and can increase its effectiveness. Parasitoids. Diadegma semiclausum is one of the parasitoids that can suppress the population of P. xylostella pests on cabbage plants to a non-detrimental extent or below the economic threshold. The purpose of this study was to determine the types of refugia that effectively preserve the parasitoid D. semiclausum around Tomohon City cabbage plants. The research method used is the survey method. Observations were carried out using self-adhesive traps, insect nets, and direct observations on plants that produce flowers vegetables, flowers, and weeds around cabbage plants in Paslaten, Rurukan, Kakaskasen I, and Wailan Villages. The data obtained were analyzed descriptively to determine the type of plant that invited the most presence of the parasitoid insect D. semiclausum as an effective refugium. Based on observations, it turns out that the effective refugia for D. semiclausum parasitoids is the Green Mustard plant. Plants that are visited by many other insects are Green Mustard plants, Legetan Weeds, Japanese Jasmine, and Carrots. Keywords: Refugia, Pest, Parasitoid, D. semiclausum, P. xylostella Abstrak Refugia merupakan tanaman yang digunakan dalam budidaya tanaman yang menyediakan makanan berupa nektar dan embun madu yang dibutuhkan oleh imago parasitoid sehingga dapat melangsungkan kehidupannya dan dapat meningkatkan efektifitasnya. Parasitoid. Diadegma semiclausum adalah salah satu parasitoid yang dapat menekan populasi hama P. xylostella pada tanaman kubis sampai batas yang tidak merugikan atau di bawah ambang ekonomi. Tujuan dari penelitian ini adalah untuk mengetahui jenis-jenis refugia yang efektif melestarikan parasitoid D. semiclausum di sekitar pertanaman kubis Kota Tomohon. Metode penelitian yang digunakan adalah metode survey. Pengamatan dilakukan dengan menggunakan perangkap berperekat, net serangga dan pengamatan secara langsung pada tanaman yang menghasilkan bunga baik sayuran, bungaan dan gulma yang ada di sekitar pertanaman kubis di Desa Paslaten, Rurukan, Kakaskasen I dan Wailan. Data yang diperoleh dianalisis secara deskriptif untuk menentukan jenis tanaman yang mengundang paling banyak kehadiran serangga parasitoid D. semiclausum sebagai refugia efektif. Berdasarkan hasil pengamatan ternyata bahwa refugia yang efektif bagi parasitoid D. semiclausum adalah tanaman Sawi Hijau. Tanaman yang banyak dikunjungi serangga lainnya adalah tanaman Sawi Hijau, Gulma Legetan, Melati Jepang dan Wortel. Kata Kunci: Refugia, Hama, Parasitoid, D. semiclausum, P. xylostella
