Abstract


The study aims to identify of white grub attacking lawn in the park of campus of University of Gadjah Mada (UGM), Yogyakarta. Observations were conducted since July 2008 until January 2010. The results showed that Lepidiota stigma is a pest cause damage to the grass in the UGM park. The presence of beetles occurred in October of the same beginning of the rainy season. Flight and lay eggs period lasted from October 2009 until January 2010. First instar larvae of L. stigma began there in November and the third instar in the month of January 2010. Factors supporting the attack of L. stigma in the college environment is the availability of grass throughout the year, as the lights and the presence of trees as shelter for adult beetles.

 

Penelitian bertujuan untuk mengidentifikasi jenis uret perusak akar rumput halaman di lingkungan taman kampus Universitas Gadjah Mada (UGM), Yogyakarta. Pengamatan dilakukan di halaman Kantor Pusat Tata Usaha (KPTU) UGM sejak bulan Juli 2008 sampai Januari 2010. Hasil menunjukan bahwa Lepidiota stigma merupakan hama penyebab kerusakan akar rumput di lingkungan taman kampus UGM. Kehadiran kumbang L. stigma di halaman taman terjadi pada bulan Oktober bersamaan awal musim hujan. Periode penerbangan dan peneluran berlangsung sejak bulan Oktober 2009 sampai dengan Januari 2010. Uret L. stigma instar pertama mulai ada bulan November dan berkembang sampai instar ketiga di bulan Januari 2010. Faktor pendukung serangan uret L. stigma di lingkungan kampus adalah ketersediaan rumput sepanjang tahun, lampu penerangan sebagai penarik kehadiran dan pepohonan sebagai tempat berlindung kumbang dewasa.
