Abstract

ABSTRAK. Penggerek batang merupakan masalah utama pada budidaya mangga di wilayah rendah basah. Informasimengenai hama ini masih sangat sedikit, sehingga upaya untuk mendapatkan teknologi pengendalian agak sulitdilakukan. Penelitian bertujuan untuk mengumpulkan data mengenai jenis penggerek, tingkat serangan OPT padabeberapa lokasi dan varietas mangga, serta eksplorasi untuk mendapatkan musuh alaminya. Penelitian dilakukandengan metode survai mulai Januari 2005 sampai dengan Desember 2006. Hasil penelitian menunjukkan bahwahama penggerek yang menyerang tanaman mangga di Sumatera Barat dan Sumatera Utara adalah Rhytidodera integra(Coleoptera: Cerambycidae) (Kolbe 1886). Selain didominasi jenis hama tersebut, di Kebun Percobaan Balai PenelitianTanaman Buah Tropika juga ditemukan jenis lain, yaitu spesies Palimna annulata Oliver (Coleoptera: Cerambycidae).Perilaku kedua jenis hama tersebut sama, yaitu menyerang mangga mulai dari pucuk kemudian menuju ke bagianbatang utama. Hama penggerek batang menyerang hampir semua varietas yang ditemui dan ditemukan di semuadaerah yang disurvai. Tingkat serangan rerata hama penggerek batang di Sumatera Barat 8,83% dan di Sumatera Utara10,36%. Varietas mangga yang terserang paling parah di Sumatera Barat adalah Cengkir (23,26%) dan di SumateraUtara adalah Podang (19,01%). Lima jenis agens pengendali biologi hama penggerek batang mangga ditemukanselama pelaksanaan survai. Hasil penelitian ini dapat digunakan sebagai informasi awal untuk menyusun teknologipengendalian hama penggerek batang mangga.ABSTRACT. Muryati, M. Istianto, and Affandi. 2010. Some Bioecological Aspects of Mango Stem Borer.Stem borer is the most important pest on mango in the wet lowland area. The information about this pest was stillvery limited, therefore, it is difficult to arrange its control strategy. The research were intended to collect data on thespecies of stem borer from some locations, its damage severity on some mango varieties as well as its natural enemies.The study was conducted by survey method from January 2005 to December 2006. The research revealed that thestem borer found in some locations was dominated by Rhytidodera integra (Coleoptera: Cerambycidae) (Kolbe 1886).Besides this species, another Cerambycidae, i.e. Palimna annulata Oliver was also found at Aripan Research Stationof Indonesian Tropical Fruit Research Institute. Both species have a similar behavior. The stem borer attacked almostall varieties that were found in research locations. The damage severity of mango by stem borer was 8.83 and 10.36%in West Sumatera and in North Sumatera, respectively. The most severe damage of mango variety in West Sumaterawas Cengkir (23.26%), while in North Sumatera was Podang (19.01%). Five species of natural enemies were foundduring the study. The results of this experiment can be used as initial information to control mango stem borer

Abstract

The research objective was to quantify the development and survivorship rate of S. dorsalis in different phenological stages of mango and selected weeds. The research was conducted in the laboratory of PT. Trigatra Rajasa, Mango plantation in Ketowan, Arjasa, Situbondo, East Java, Indonesia from February to September 2015. The development and survivorship rate were done through observation of life span of S. dorsalis from egg to pupa. Analysis of Variance and Duncan Multiple Range Test (p = 0.05) with 5 replications were applied to ensure the significant differences among the treatments. The result showed that development and survivorship of Scirtothrips dorsalis were supported by mango flushes and flower as well as some weeds such as Leucania leucochepala, Ipomoea triloba, Achalypha indica, Desmanthus leptophyllus and Azadirachta indica as source of food. Achalypha indica was the most suitable host with development time (12.82 ± 0.21 days) and survivorship (33 %). Weed Tridax procumbent, Momordica charantia and Mimosa pudica were unable to provide the living requirement for immature developmental stage of S. dorsalis.
