<![CDATA[ABSTRACTThe use of chemical pesticide has been limited considering its negative impact for the environment. Information about biological insecticide as worm Heortia vitessoides pest of agarwood is still limited. This research aimed to determine biological insecticide effectiveness of leaves and seed of suren, neem, and soursop as H. vitessoides worm controler. The research has been conducted in Forest Protection Laboratory of Forestry Research Institute of Banjarbaru. Researh used complete random design with 6 treatments and 3 replications. Research result showed that seed extract indicated high effect of insecticide compared to leaves. The highest mortality occurred on neem seed extract with concentration of 3% and 4%, and soursop seed extract of 4% concentration caused mortality of H. vitessoides larva as 100%, while on suren seed extract of 4% concentration mortality occurred as 53.33%. Type and concentration of insecticide had a significant effect on H. vitessoides larva mortality.ABSTRAKPenggunaan pestisida kimia dewasa ini mulai dibatasi, mengingat dampak negatif yang ditimbulkan terutama bagi lingkungan. Informasi tentang insektisida nabati sebagai pengendali hama ulat daun gaharu Heortia vitessoides masih terbatas. Penelitian ini bertujuan mengetahui efektifitas insektisida nabati ekstrak daun dan biji tanaman suren, mimba dan sirsak sebagai pengendali ulat H. vitessoides. Penelitian dilakukan di Laboratorium Perlindungan Hutan, Balai Penelitian Kehutanan Banjarbaru. Penelitian menggunakan Rancangan Acak Lengkap dengan 6 perlakuan 3 ulangan. Hasil penelitian menunjukkan bahwa ekstrak biji memberikan efek insektisidal tinggi dibandingkan dengan daun. Mortalitas paling tinggi terjadi pada perlakuan ekstrak biji mimba konsentrasi 3% dan 4% serta ekstrak biji sirsak konsentrasi 4% yang menyebabkan mortalitas larva H. vitessoides sebesar 100%, sedangkan ekstrak biji suren konsentrasi 4% memberikan efek mortalitas sebesar 53,33%. Jenis insektisida dan konsentrasi berpengaruh nyata terhadap mortalitas larva H. vitessoides.]]>
