Abstract

The research on the mortality and growth of Cryptolestes ferrugineus on IR-64 rice variety at the room temperatures of 20°C, 25°C, 30°C, 35°C and 40°C was done at the Pest Laboratory, Department of Plant Pest and Disease, Agriculture Faculty, University of Brawijaya, Malang. The results showed that C. ferrugineus could not survive at 40°C room temperature. The highest mortality of C. ferrugineus imago occurred at 40°C. Eggs produced by adult C. ferrugineus at 40°C cannot hatch into larvae, so development stops during the egg phase. The number of eggs of C. ferrugineus is produced more at room temperature 25°C than room temperature 20°C, 30°C, 35°C, and 40°C by showing the number of eggs at room temperature 25°C(85.20 items) more higher than the room temperature of 20°C(46.40 items), 30°C(55.40 items), 35°C (63.40 items) and 40°C (10.20 items)

Abstract

Cryptolestes ferrugineus (Cucujidae: Laemophloeidae) is a postharvest secondary pest of rice and other food commodity products. The distribution of C. ferrugineus covers tropical or subtropical climates with high humidity. Temperature fluctuations that occur every day affect development C. ferrugineus. The development of the life phase of C. ferrugineus largely determines the amount of its population and its massive impact on the damage caused to storing material. This research was conducted to determine the effect of several levels of room temperature on the development time of C. ferrugineus. The room temperature used in this study was 20°C, 25°C, 30°C, 35°C, and 40°C and was repeated five times. The results showed that the shortest development time of the insect pest C. ferrugineus (26.75 days) occurred at a room temperature of 30°C with a humidity of 68% compared to other room temperatures. The slowest development time for C. ferrugineus occurs at 25°C (42.60 days). At room temperature 40°C eggs produced by adult female C. ferrugineus cannot develop into larvae, so the development C. ferrugineus at 40°C was cut off.

Abstract

Hama gudang menyebabkan kerusakan bahan simpan terbesar di tempat penyimpanan karena serangga hama gudang memiliki kemampuan berkembang biak yang cepat, mudah menyebar dan dapat mengundang pertumbuhan jamur. Salah satu hama gudang yang menyerang komoditas beras yaitu, Cryptolestes ferrugineus. Ketahanan hidup dan perkembangan C. ferrugineus  sangat menentukan jumlah populasinya saat menginfestasi bahan simpan. Penelitian ini dilakukan untuk mengetahui pengaruh suhu 20°C, 25°C, 30°C, 35°C, dan 40°C terhadap mortalitas jantan dan betina serta mengetahui berat imago yang terpapar suhu di dalam Inkubator. Hasil penelitian menunjukkan bahwa rerata mortalitas tertinggi terjadi sejak 24 jam pertama infestasi imago C. ferrugineus pada suhu 40°C dengan tingkat kelembaban 35% sampai 7 hari infestasi sebesar 8,03%. Tingkatan suhu tidak berpengaruh nyata terhadap berat imago C. ferrugineus di inkubator.

Abstract

Flight Activities and Population Development of Thrips parvispinus Karny (Thysanoptera: Thripidae) on Chili (Capsicum annuum L.). Thrips parvispinus Karny (Thysanoptera: Thripidae) is one of the main pests on chili. T. parvispinus attacked the leaves and flowers on chili. The behavior of its attacked fluctuate between morning until late afternoon since the plants grow in the field. The purpose of this research was to know the flight activity of T. parvispinus and its population development on leaf and flower of chilli plant. The research used survey method with direct observation on plants in the field. Flight activity of T. parvispinus was measured by using a yellow sticky trap placed diagonally on the plant. The results showed that daily flight activity of adult T. parvispinus fluctuated between morning, afternoon, and evening. The highest flight activity of adult occurred at 09.00-10.00 (39.81 adults) and the lowest was at 18.00-19.00 (9.84 adults). The population of T. parvispinus nymph was more than adult in the leaf. The highest population of nymphs occurred at 12.00-13.00 (21.07 nymphs). While the population of T. parvispinus adul was more on flower than nymph population. The highest adult population occurred at 18.00-19.00 (27.36 adults). There were strong indications that the nymph stadium frevers live on the part of the leaf than the flower, while the adult prefers the flower rather than the leaf.

Abstract

Diversification of renewable energy sources is needed to anticipate the depletion of fossil energy sources. One of the renewable energy sources is biodiesel from vegetable oil. This study aims to determine the oil yield of wild plant seeds found on Serangan Island. The method used is the exploration method, namely by going around Serangan Island and then collecting ripe fruit for harvesting the seeds. The fruit is dried and then the dimensions of the fruit and seeds are measured. The oil was extracted from the seeds by the soxhletation method using hexane as a solvent. Oil producing plant species identified. The results showed that there were 10 types of plants with very varied fruit and seed sizes. The oil yields from highest to lowest respectively were as follows: Terminalia catappa 29.3%, Dialium indum, 28.2%, Cesalphinia pulcherima 27.7%, Bauhinia purpurea L 26.5%, Leucaena leucocephala 16.3%, Caesalpinia bonducella 15.7%, Riccinus communis 13.5%, Delonix regia 11.3%, Manilkara kauki 11.2%, and Mimusops eleng 11%.

Abstract

Sweet potato production fluctuates every year, one of the factors causing the decline in production is the presence of pests and diseases. Sweet potato leaf curl virus (SPLCV) has been reported to infect sweet potatoes in Indonesia in 2022. Until now, there is no information regarding the variation in symptoms and severity of SPLCV disease in sweet potatoes. Therefore, this study aims to analyze the variation in symptoms and severity of SPLCV disease in Gianyar, Bali. The research was carried out directly in the field with observational parameters such as symptoms variation, incidence and disease severity. Observations were made every week when the plants were 63 to 91 days after planting (DAP). The results showed that SPLCV causes a variety of symptoms in the form of mild vein clearing, severe vein clearing, upward vein clearing, and downward vein clearing. The incidence and severity of the disease has increased every week. The incidence and severity of the disease were highest when the plants were 91 DAP, namely 73.33% and 40%, respectively. The high incidence and severity of the disease in the field is due to the use of stem cuttings from previous plants which may have been infected with SPLCV and whitefly vectors are always found in the field.
