Abstract

This research purposed to study biology of Helopeltis sp. on cocoa and cucumber fruits. Research was done in insect bioecology laboratory using direct observation with 10 replications for each fruit. Parameter observed were copulation (hours), preoviposition time (days), number of eggs, nymphals, and adult periods (days), Oviposition time (days), and post oviposition time (days). The data obtained were analyzed descriptively and compared with t-test. Result of this research showed that Helopeltis sp. could thrive in cacao and cucumber fruits. Adult of Helopeltis sp. longevity in cacao fruits was 16 days and in cucumber fruits was 13 days. The number of eggs product average 10-10.9 eggs/female.

Abstract

Trichoderma harzianum culture filtrate is widely used to control plant pathogenic fungi because it contains secondary metabolites which act as antifungal. This study aimed to determine the ability of T. harzianum culture filtrate at various concentrations to suppress the growth of Fusarium fujikuroi cause of bakanae disease in rice. The study consisted of 2 stages: 1. in the laboratory and 2. in the screen house using a Completely Randomized Design (CRD) consisting of 6 treatments and 5 replications. The treatments were T. harzianum culture filtrate concentrations, namely A, 0%, B. 25%, C. 50%, D.75%, E. 100% and F. control (without filtrate and without F. fujikuroi). Parameters observed for stage I (in the laboratory) i.e. the percentage of seeds attacked by F. fujikuroi, colony thickness and colony area and parameters observed for stage 2 (in the screen house) i.e. the number of seedlings appearing, the seeds showing symptoms of bakanae, dead seeds, dead seedlings and stunting seeds. The results showed that the T. harzianum culture filtrate was able to suppress the growth of F.fujikuroi at both in the laboratory and in the screen house. The best filtrate concentration was 100% with the inhibition on the colony area of 77.38%, the number of seeds germinating of 55.78%, seeds showing bakanae of 80.06%, dead seeds of 60.09%, dead seedlings of 52.97%, and stunting seedlings of 60.09%

Abstract

Branch dieback is one of the primary diseases in cacao plants. The disease affects young shoots and twigs, causes leaves to die, and leaves them bare, interfering with photosynthesis. This study aimed to determine the causative pathogens in Padang City. The locations were: Sungai Sarik Kuranji, Lubuk Minturun Koto Tangah, and Teluk Kabung Bungus. The locations have the following criteria: age ? three years, the number of plants at the location ? 50 individuals, and found symptoms of branch dieback. The research used descriptive methods. The sample represented 10% of the total number of plants at the location, was collected randomly. The results found four species of fungi associated with the disease, namely Oncobasidium theobromae, Botrydiplodia theobromae, Fusarium decemcellulare, and Fusarium sp1.

Abstract

Some flowering plants like common zinnia (Zinnia elegans (Jacq) Kuntze), marigold (Tagetes erecta Linnaeus), and cockscomb flowers (Celosia sp.) have been used as refugia and conservation plants for predators and parasitoids but are still not yet optimal. Planting refugia plants can affect insect diversity and evenness index, affecting the stability and balance of the agroecosystem. The study aimed to determine the effect of common zinnia, cockscomb flowers, and marigold as refugia on insects’ diversity and evenness index and their potential as a medium for conservation of predators and parasitoids. The study was conducted in organic rice fields in Batang Anai Sub-district, Padang Pariaman District, West Sumatra, from May to July 2020. The Insect was collected from plots covering an area of ??48 m2 and identified in the Bioecology laboratory, Faculty of Agriculture, Universitas Andalas. Planting common zinnia, marigolds, and cockscomb flowers increased the index of diversity and evenness of insects around rice fields. The index of diversity and evenness of insects on cockscomb flowers (H = 2.90) was higher than that of common zinnia (H = 2.61) and marigold (H = 2.63). Cockscomb flowers have more potential as a medium for conserving predators and parasitoids.
Resistance Test of Some Rice Varieties to Brown Planthopper (Nilaparvata lugens Stal) Bogor Population Using Honey: Uji Resistensi Beberapa Varietas Padi terhadap Wereng Batang Coklat (Nilaparvata lugens Stal) Populasi Bogor Menggunakan Metode Honeydew Test Rinaldi, James; Sari, Widya Puspita; Darmadi, Dedi; Nelly, Novri

Abstract

Brown planthopper or BPH (Nilaparvata lugens Stal, Hemiptera: Delpachidae) is a significant pest that is a severe problem to rice plants in various places, including Bogor District, East Java Province. Resistance of several varieties of rice to BPH of Bogor Population has not been reported. One method to determine a variety's resistance is the honeydew test. This study aims to determine the resistance of several rice varieties to BPH of Bogor population. This study used six different varieties as treatments, and carried out in five replications. Those varieties were Pelita, Mapan, Situ Bagendit, Ciherang, Inpari-33, and IR-64. The observations were made on the area of honeydew spots produced by BPH after consuming sap of rice plant. This research showed that the Situ Bagendit variety was relatively resistant to BPH of Bogor population. The Mapan and Pelita varieties were quite susceptable, while Inpari-33, Ciherang, and IR-64 were moderate. The region of origin where BPH grows and the testing procedure can affect the resistance category of one variety.

Abstract

The density and attack rates of Spodoptera frugiperda have been reported in various maize cultivation in Indonesia, but there has never been a report in Sijunjung District, West Sumatra. The research was conducted to study the attack level, density, and distribution of S. frugiperda in Sijunjung District. The study was carried out in March -May 2023 using a survey method in 8 sub-districts in Sijunjung District. The results showed that S. frugiperda had spread and attacked maize crops evenly in Sijunjung District, but the attack rate (26.96%) and density (0.24 individuals) were low. The highest attack was found in Nagari Guguak (88.7%). The high or low rate of attacks is influenced by differences in varieties, planting ages, and maize cultivation techniques. Meanwhile, the density is more influenced by age differences.

Abstract

Wereng perut putih (Stenocranus pacificus Kirkaldy) merupakan salah satu hama yang menyerang tanaman jagung di Kabupaten Padang Pariaman. Penelitian ini bertujuan untuk mengetahui kepadatan populasi dan gejala serangan wereng perut putih pada tanaman jagung yang ditanam secara monokultur di kabupaten Padang Pariaman. Penelitian ini dilaksanakan pada lahan pertanaman jagung milik petani di nagari Pakandangan dan nagari Gadur, Kecamatan Enam Lingkung, dan nagari Campago, kecamatan V Koto Kampung Dalam, Kabupaten Padang Pariaman, Provinsi Sumatera Barat. Penelitian ini dilaksanakan pada bulan Februari – Mei 2025. Metode yang digunakan dalam penelitian ini adalah metode survei, dengan pemilihan lahan sampel ditetapkan dengan kriteria luas area minimal 1 Ha. Pada setiap lahan ditentukan sebanyak 5 petak sampel yang ditentukan secara diagonal, yaitu 1 petak terletak di perpotongan garis diagonal dan 4 petak lainnya terletak pada garis diagonal dengan jarak 5 m dari sudut petakan. Setiap petak sampel berukuran 1 x 1m. Masing-masing petak sampel terdiri dari 12 tanaman jagung, sehingga jumlah sampel tanaman jagung yang diamati secara keseluruhan sebanyak 60 tanaman. Data diolah dengan excel. Hasil penelitian menunjukkan bahwa kepadatan populasi dan serangan S. pacificus pada tanaman jagung di Kabupaten Padang Pariaman sangat dipengaruhi oleh jenis varietas tanaman jagung. Selain itu, kepadatan populasi S. pacificus cenderung lebih tinggi pada fase vegetatif dibandingkan fase generatif
