Abstract

Bawang merah (Allium cepa L.) merupakan komoditas hortikultura penting dengan nilai ekonomi tinggi di Indonesia. Salah satu kendala dalam budidaya bawang merah adalah serangan hama, khususnya ulat bawang merah (Spodoptera exigua Hubner). Penggunaan predator cecopet (Euborellia annulata Fabricus) dapat menjadi alternatif untuk pengendalian hayati S. exigua. Penelitian ini bertujuan untuk mendapatkan daya pemangsaan cecopet (E. Annulata Fabricus) terhadap ulat bawang merah (S. Exigua Hubner) di laboratorium. Penelitian dilakukan di Laboratorium Hama Tumbuhan, Fakultas Pertanian, Universitas Riau, dari Januari hingga Maret 2025. Penelitian ini menggunakan rancangan acak lengkap (RAL) yang terdiri dari lima perlakuan dan empat ulangan. Perlakuan yang digunakan adalah satu imago predator betina, satu imago predator jantan, dua imago predator betina, dua imago predator jantan, dan sepasang imago predator E. annulata. Hasil penelitian menunjukkan bahwa predator cecopet (E. annulata Fabricius) mampu memangsa hama ulat bawang (S. exigua Hübner). Pemberian dua predator betina menghasilkan daya pemangsaan sebesar 20,75 ekor/hari dengan persentase pemangsaan cenderung tinggi sebesar 83%. Pemberian sepasang predator menghasilkan daya pemangsaan sebanyak 18,50 ekor/hari dengan persentase pemangsaa 74%, diikuti oleh dua predator jantan sebanyak 17,00 ekor/hari (68%), satu predator betina sebanyak 14,75 ekor/hari (59%), dan satu predator jantan sebanyak 13,50 ekor/hari dengan persentase pemangsaan sebanyak 54% .

Abstract

Bukit Tiga Puluh National park (TNBT) of Riau Province is a nature conservation area with a high diversity of fauna, one of which is the butterfly. Butterfly species diversity is influenced by the vegetation in their habitat. The TNBT utilization zone has a habitat type with varied vegetation. There is no information about the species of butterflies in the area. This study aimed to identify morphological character of butterflies and vegetation based on morphological characters. The method used was exploration. The catching area of the butterfly was the Granite waterfall and the Bukit Lancang path of TNBT utilization zone. Samples made as insectarium and herbarium. The  identification of butterfly characters consisted of the head, thorax, abdomen, legs and wings. There were a number of different types of butterflies and plants between the Granite waterfall area (22 and 28 species) and the Bukit Lancang paths (5 and 9 species). The type of butterfly was dominated by the family Nymphalidae. This is due to the amount of vegetation and environmental conditions that are more favorable in the granite waterfall area. The key determinants of butterfly species are the characters of the wing. The results of this study can contribute to maintaining the TNBT butterflies in Riau Province and also as database information of butterflies species in Indonesia.

Abstract

[CONCENTRATION OF LOCAL ENTOMOPATHOGENIC NEMATODE Steinernema carpocapsae Weiser AGAINST CORN COB BORER Helicoverpa armigera Hübner IN LABORATORY BIOASSAYS]. Corn (Zea mays L.) ranks among Indonesia's most vital food crops. However, production in Riau Province has declined due to infestations by the corn cob borer (Helicoverpa armigera Hübner), which can damage up to 39.7% of crops. Conventional control relies on synthetic chemical insecticides, which pose persistent risks including mortality of natural enemies, pest resistance, and population resurgence. An eco-friendly alternative involves local entomopathogenic nematodes (EPN), Steinernema carpocapsae Weiser, which induce rapid host mortality (within 24–48 hours) via symbiotic bacteria producing lethal toxins. This study determined the best concentration of S.carpocapsae infectious juveniles (IJ) for H. armigera mortality under laboratory conditions. An experimental approach employed a completely randomized design (CRD) with five concentrations (0, 250, 500, 750, and 1000 IJ/mL distilled water) and four replicates per treatment. Parameters assessed included EPN identification, time to initial mortality, and total mortality. Data were subjected to analysis of variance (ANOVA) followed by DNMRT test at 5% significance. Results revealed that 750 IJ/mL was the most effective concentration, achieving 80% total mortality within 72 hours post-application. These findings support S. carpocapsae at 750 IJ/mL as a viable biocontrol agent for H. armigera in integrated pest management (IPM) programs, warranting field trials to validate efficacy under Riau's agroecological conditions.
