      Abstract
      Puru merupakan salah satu ciri pertumbuhan abnormal dari jaringan tanaman yang disebabkan oleh serangga fitofag maupun patogen. Puru dapat menghambat laju fotosintesis sehingga tanaman menjadi kerdil ataupun mati, maka jenis-jenis serangga penyebab puru sangat penting untuk diketahui sebagai langkah awal pengendalian hama. Penelitian ini bertujuan mengetahui karakteristik puru yang terbentuk, serta jenis serangga penyebab puru pada spesies Eucalyptus urophylla (ampupu) di Hutan Penelitian Cikole, Lembang, Bandung. Sampel diambil dari lapang secara purposive sampling dan selanjutnya dilakukan di laboratorium. Hasil pengamatan menunjukkan bahwa serangga menginduksi puru pada bagian daun saja, terbentuk delapan karakter gejala puru yang dikategorikan berdasarkan warna dan ukurannya, serta ditemukan dua jenis serangga, yaitu Ophelimus eucalypti dan Ophelimus maskelli yang terkonfirmasi sebagai serangga penginduksi puru. Kedua serangga tersebut merupakan serangga yang termasuk dalam Ordo Hymenoptera dan Famili Eulophidae. Berdasarkan hasil analisis data, ditemui bahwa insidensi serangan pada lahan ampupu di HP Cikole mencapai 54% dan dikategorikan sebagai kerusakan ringan dan tingkat keparahan sebesar 22%.
       
      Gall was one of the characteristics of abnormal growth of plant tissue caused by phytophagous insects and pathogens. Gall was able to inhibit the rate of photosynthesis and caused plant growth to be stunted or lead to death. This study aimed to determine the characteristics of the gall formed, and the type of gall-inducing insects in the Eucalyptus urophylla (ampupu) species in the Cikole Research Forest (HP), Lembang, Bandung. Samples were taken using purposive sampling method in the field and then identified at the laboratory. The type of gall-inducing insects was important to be known as the first step in pest control. Observations showed insects only induced leaves, formed eight gall symptom characters categorized by color and size, and found two types of insects, Ophelimus eucalypti and Ophelimus maskelli which were confirmed as gall-inducing insects. Both gall-inducing insects are classified into Order Hymenoptera and the Family Eulophidae. Based on the results of data analysis, it was found the incidence of attack on the ampupu land in HP Cikole reached 54% and was categorized as light damage with a severity level of 22%.
