This research aims to determine the viability of subterranean termites (Coptotermes curvignathus Holmgren) in some media wood in laboratory. The study was conducted at Plant Pest Laboratory, Agroecotechnology Program Study, Faculty of Agriculture, University of Sumatera Utara, Medan from March to May 2014. It was done by using Completely Randomized Design (CRD) non factorial with ten treatments and three replications: control, rubber wood, jackfruit wood, mango wood, guava wood, tead, duku wood, palm wood, mahogany and guava wood. The results showed that the highest mortality in mahogany wood 8.04%. The lowest residue of wood was in mahogany 0.84 g.Keywords: Coptotermes curvignathus, mortality, wood

The influence of Cordyceps militaris on Coptotermes curvignathus Holmgren. (Isoptera: Rhinotermitidae) mortality in laboratory. This research was to study influence of entomophatogen fungus C. militaris against C. curvignathus in laboratory. This study was conducted in Pest Laboratory of Agriculture Faculty, University of Sumatera Utara, Medan during of October 2014 with using completely randomized design (CRD) nonfactorial with nine treatments and three replications : control, C. militaris sprayed (10, 20, 30 and 40 g/ 100 ml water), C. militaris sowed (10, 20, 30 and 40 g). The results showed that the highest mortality (100%) of C. militaris on sprayed 30 and 40 g/ 100 ml water and sowed 30 and 40 g in seventh day; the lowest (78.33%) on C. militaris sprayed 10 g/ 100 ml water. Termites was infected by C. militaris suffered mimification and after a few days the colonies was growth with white colored (micelium) around the body. The fastest of mortality time at 50% was 3.67 days on C. militaris sowed 40 g and the longest was 5.00 days on C. militaris sprayed 10 g/ 100 ml water and C. militaris sowed 10 g.Keywords : Coptotermes curvignathus, Cordyceps militaris, mortality, spray, sowe

Distribusi Peta Awal Serangan Penyakit Jamur Akar Putih (Rigidoporus microporus (Swartz: Fr)) pada Beberapa Perkebunan Karet Rakyat di Kabupaten Asahan Maya Sari Rahayu; Lahmuddin Lubis; Syahrial Oemry

Kabupaten Asahan merupakan wilayah pertanaman karet yang masih rendah produktivitasnya di Sumatera Utara, salah satu penyebabnya adalah penyakit jamur akar putih dengan kerugian mencapai Rp. 1 miliar (8.53%) per tahunnya. Penelitian bertujuan untuk melakukan pemetaan serangan penyakit dan mengetahui keparahan penyakit jamur akar putih pada beberapa perkebunan karet rakyat di Kabupaten Asahan. Penelitian dilaksanakan di kebun karet rakyat Desa Aek Teluk Kiri Kecamatan Teluk Dalam, Desa Kampung Baru dan Silomlom Kecamatan Simpang Empat, Desa Sei Pulo Pale dan Sei Alim Ulu Kecamatan Air Batu dan Laboratorium Riset dan Teknologi Fakultas Pertanian, Universitas Sumatera Utara pada bulan Juli sampai Oktober 2015. Penelitian menggunakan metode survei dan pembuatan peta menggunakan Sistem Informasi Geografis. Hasil penelitian menunjukkan distribusi peta serangan penyakit jamur akar putih tersebar pada letak geografis 2°83.167'54.5" - 2°91.055'23.4" LU dan 99°61.997'34.7" - 99°73.535'64.9" BT, keparahan penyakit tertinggi terdapat di kebun Desa Sei Alim Ulu Kecamatan Air Batu yaitu 52,50%, terendah di kebun Desa Silomlom Kecamatan Simpang Empat yaitu 3,10%. Hasil rata-rata kuisioner menunjukkan bahwa kurangnya keperdulian para petani dalam melakukan pengendalian yang optimal sehingga serangan penyakit dapat menyebar cepat.

Penyakit kuning merupakan salah satu penyakit yang terdapat pada tanaman cabai (Capsicum annum) yang disebabkan oleh vektor hama kutu kebul (Bemisia tabaci). Tujuan penelitian ini adalah untuk mengetahui hubungan antara populasi kutu kebul dengan kejadian penyakit kuning pada tanaman cabai di dataran rendah. Penelitian ini dilaksanakan pada bulan Maret sampai dengan April 2016. Hasil penelitian menunjukkan bahwa populasi kutu kebul berpengaruh sangat kuat terhadap persentase kejadian penyakit kuning dengan nilai korelasi 0,866. Rata-rata persentase kejadian penyakit kuning di dataran rendah adalah 86,17 %. Persentase kejadian penyakit tertinggi yaitu di desa Suka Rende sebesar 94,3 % diikuti Desa Suka Ramai 85 % dan persentase terendah di desa Sei. Semayang sebesar 79,2 % Kata Kunci : Bemisia tabaci Genn, penyakit kuning, populasi, cabai

ABSTRACT Fruit flies is an important pest for citrus. This research was aimed to determine the effect of (Bractocera dorsalis Hendel.) fruit flies against attractant compounds that contain protein and the height of the trap on the number of catches of fruit flies in the planting of sweet oranges (Citrus sinensis L.). and differences in the sex ratio of fruit flies. This study used a non factorial randomized block design with 9 treatments namely: T0(compound ME 100 cm high), T1(ME compound and cocoa waste 85 cm high), T2(ME compound ME and cocoa waste 135 cm high), T3(ME compound ME and cocoa waste 185 cm high),T4(ME compound and cocoa waste 235 cm high), T5(ME compound and tempe waste 85 cm high), T6(ME compound and tempe waste 135 cm high), T7(ME compound and tempe waste 185 cm high),and T8(ME compound and tempe waste 235 cm high). The results showed that the : type of fruit fly trapped was species of B. dorsalis. In the week four, it was found that the largest population of fruit flies was trapped 155 imago. Treatment cocoa waste was effective in trapping fruit flies in weeks 1-4 with a mean of 12,33 fruit flies and treatment tempe waste trapping fruit flies at week 5 with an average of 8,67 fruit flies. The trap height that is effective at trapping fruit flies is 85 cm. The number of male trapped were 443 males and 19 females with a ratio of 1: 17 and 1 : 26 sex ratio.
