Effectiveness test entomopathogenic nematodes Steinernema sp. at the coffee berry borer pest (Hypothenemus hampei Ferr.) (Coleoptera: Scolytidae) in the laboratory.

Abstract

Effectiveness test entomopathogenic nematodes Steinernema sp. at the coffee berry borer pest
(Hypothenemus hampei Ferr.) (Coleoptera: Scolytidae) in the laboratory. The aimed of the research
was to determinethe effect of application of Steinernema sp. to controlH. hampei. This research was
conducted at the Laboratory of Plant Disease, Faculty of Agriculture, University of Sumatera
Utara, Medan at an altitude of ± 25 meters above sea level, from November 2014 to April 2015.
The research used Complete Randomized Design (Non Factorial) with various nematodes level.
They were N0(No nematode/control), N1 (68 JI / ml), N2 (138 JI / ml), N3 (208 JI / ml). The
parameters observed were the symptoms of an attack and the percentage of mortality H. hampei.
The results showed that the best result to control H. hampei was showed on treatment N3 (208JI /
ml) with a percentage of mortality by 82 % .

Uji efektifitas nematoda entomopatogen Steinernema sp. pada hama penggerek buah kopi (Hypothenemus hampei Ferr.) (Coleoptera : Scolytidae) di Laboratorium. Tujuan penelitian untuk mengetahui pengaruh aplikasi nematoda entomopatogen Steinernema sp. dalam mengendalikanH.hampei. Penelitian ini dilaksanakan di Laboratorium Penyakit Tanaman, Fakultas Pertanian, Universitas Sumatera Utara, Medan pada ketinggian ± 25 mdpl, dari bulan November 2014 sampai April 2015. Penelitian menggunakan Rancangan Acak Lengkap (Non Faktorial) dengan faktor perlakuan nematoda berbagai taraf yaitu N0 (tanpa nematode/kontrol), N1 (68 JI/ml), N2 (138 JI/ml), N3 (208 JI/ml). Parameter yang diamati adalah gejala serangan dan persentase mortalitas H. hampei. Hasil penelitian menunjukkan bahwa perlakuan terbaik untuk mengendalikan H. hampei terdapat padaperlakuan N3 (208JI/ml) dengan persentase mortalitas sebesar 82 %.
