Abstract

Oryctes rhinoceros L (Coleoptera: Scarabidae) merupakan salah satu hama penting pada tanaman kelapa sawit. Hama ini dapat menurunkan produksi tandan buah segar (TBS) pada tahun pertama menghasilkan hingga 69%, bahkan menyebabkan tanaman muda mati mencapai 25%. Tujuan dari penelitian ini adalah mempelajari kelimpahan populasi dan tingkat serangan O. rhinoceros pada perkebunan kelapa sawit berbatasan dengan areal replanting. Penelitian ini telah dilakukan di areal replanting perkebunan kelapa sawit milik PT. Sumber Andalas Kencana (SAK) Muaro Timpeh yang terdapat di Nagari Padang Laweh, Kecamatan Timpeh, Kabupaten Dhamasraya dari pada bulan Februari sampai dengan April 2020. Pada lokasi yang sudah ditentukan akan dipasang ferotrap sebanyak empat unit dengan jarak secara berurutan yakni 100, 400, 700, dan 1000 m dari areal replanting. Pemasangan ferotrap pada lahan kelapa sawit menggunakan feromon agregat yang mampu menarik kumbang jantan maupun betina. Ferotrap dipasang dengan cara digantung pada tiang dengan ketinggian 2.5 m. Pada masing-masing jarak digunakan lahan seluas 1 hektar dan dipasang sebanyak 1 ferotrap pada jalur produksi, hal ini bertujuan untuk menarik imago O. rhinoceros keluar dari areal perkebunan kelapa sawit. Hasil pengamatan menunjukkan terdapat perbedaan populasi O. rhinoceros pada beberapa jarak dari lokasi replanting. Dimana kelimpahan tertinggi terdapat pada jarak 700 m dari lokasi replanting dan kelimpahan paling rendah terdapat pada jarak 1000 m. Nilai rerataan populasi O. rhinoceros tertinggi pada skala jarak 700 m adalah 10.4 imago/ferotrap/bulan sedangkan nilai rata – rata terendah yaitu pada skala jarak 1000 adalah 7.3 imago/ferotrap/bulan. Pada jarak 100 m, 400 m, dan 700 m, intensitas serangan yang didapatkan yaitu 60%. Sedangkan pada jarak 1000 m, intensitas serangan yang didapatkan adalah 55%. Jadi tingkat populasi dan intensitas serangan O. rhinoceros di perkebunan kelapa sawit berbatasan dengan areal replanting tertinggi pada jarak 700 m dan paling rendah pada jarak 1000 m.

Abstract

Coccinella repanda Thunberg (Coleoptera: Coccinellidae) is one of the important predators in pest control of chili plants. However, information about this predator's biology, demography, and functional response is still limited in Indonesia. This study aimed to evaluate the potential of C. repanda by studying its biology, demography, and functional response to several species of main pest aphids on chili plants. Observations of biology and demography were conducted using five replications, with each replication treated with a pair of C. repanda. Observations of preference and predation ability of C. repanda on different prey were conducted using a factorial design with two factors and five replications. The first factor was prey exposure to different densities, and the second was the use of different prey species. Data were analyzed using variance analysis and continued with Duncan's New Multiple Range Tests (DNMRT) at the 5% level. The pre-adult and adult development periods, as well as the longevity of Coccinella transversalis (Thunberg) (Coleoptera: Coccinellidae), were studied in the laboratory using Aphis gossypii (Glover) (Homoptera: Aphididae) as prey. The results showed that the development period of C. repanda was 31.02 ± 4.73 days. During their lifespan, female adults were able to lay 90.44 ± 14.38 eggs. The demographic parameters of C. repanda were gross reproductive rate (GRR) of 74.80 individuals per generation; net reproductive rate (Ro) of 18.22 individuals per female per generation; intrinsic rate of increase (rm) of 0.46 individuals per female per day; mean generation time (T) of 12.40 days; and doubling time (DT) of the population for 1.51 days. There was no significant difference in the predation rate of C. repanda on three different prey exposed. Logistic regression analysis also revealed that C. repanda exhibited type I functional response to A. gossypii, A. craccivora, and M. persicae. These results indicate that C. repanda can be categorized as an effective biological control agent. This study is expected to contribute to developing biological pest control strategies on chili plants.

Abstract

Pollinating beetle (Elaeidobius kamerunikus Faust) and thrips hawaiiensis (Thrips hawaiiensis Morgan) are the main pollinators of oil palm. Elaeidobius kamerunikus was introduced from Cameroon in 1982 while Thrips hawaiiensis is a native pollinator that already exists in the ecosystem of oil palm plantations in Indonesia. The purpose of this study was to study the potential of Elaeidobius kamerunikus and Thrips hawaiiensis as pollinating agents in oil palm. This research was conducted in a plasma plantation belonging to the Agricultural Technology Assessment Agency (BPTP) in Nagari Gunung Medan, Sitiung District, Dharmasraya Regency, West Sumatra Province. The parameters used to measure the potential of insect pollinators are population abundance, frequency of visits, and fruit set and fruit grade values, as well as the yield of palm oil produced. Observation of abundance was carried out by directly observing the population of these insects on male flowers of oil palm that were in anthesis. The frequency of visits by Elaeidobius kamerunikus and Thrips hawaiiensis was carried out on receptive female oil palm flowers using the Fix Sample Method. Observations of the frequency of visits were carried out in the morning, afternoon and evening. Pollination effectiveness is done by looking at the value of fruit set and the grade of fruit produced. Based on the analysis of the observed data, it is known that the population abundance of Elaeidobius kamerunikus is higher than that of Thrips hawaiiensis. Likewise with the frequency of visits Elaeidobius kamerunikus visited the female oil palm flowers more often than Thrips hawaiiensis. Based on the time of observation, Elaeidobius kamerunikus visited more female oil palm flowers in the morning and afternoon, while in the afternoon the frequency of Thrips hawaiiensis visits was higher. The total fruit formed as a result of pollination of Thrips hawaiiensis was 793 consisting of 177 grade A, 145.5 grade B, and 472.50 grade C, while the fruit pollinated by Elaeidobius kamerunikus was less, namely 514.5 fruit consisting of 150 grade A, 125.5 grade B, and 239 grade C. The fruit set values produced by the two pollinator insects tested were low, namely 46.45% for Elaeidobius kamerunikus and 59.43 for Thrips hawaiiensis.

Abstract

The main principle of pest control in organic farming is to reduce the use of synthetic chemicals, especially pesticides. On the other hand, pest control in agricultural systems prioritizes the conservation of natural enemies in these ecosystems. Coccinellidae predators are one of the potential natural enemies available in organic farming ecosystems. To optimize the potential of these natural enemies, it is necessary to study the diversity of these predators in organic farming. By knowing the species and abundance of Coccinellidae predators in organic farming ecosystems, a suitable conservation model can be designed for these natural enemies so that these predators can carry out their functions to control pests, especially aphids. This study aims to study the diversity of predatory Coccinellidae in organic and inorganic agriculture in West Sumatra Province. Coccinellidae predators are collected directly and use insect nets. The diversity of Coccinellidae predators was analyzed with the Shannon Winner and Simpson abundance indexes. Based on the exploration carried out on several organic farms in West Sumatra, 18 species of Coccinellidae Predators have been collected, and six species have not been identified. Next, it is proven that organic farming has a high diversity of 1.90 compared to inorganic farming, which is 1.65. The presence of predatory Coccinellidae in organic farming is more evenly distributed, namely 0.67. Menochilus sexmaculatus is one species that has the potential to be optimized as a biological control agent for aphids.

Abstract

Information on the type of OPT that attacks plantation commodities in Buton Regency is incomplete, even though the data can be the basis for mitigating attacks and controls if the plants have been attacked. For this reason, research was conducted to identify the type and distribution of pests in plantation crops, especially in cocoa, cloves, cashew, pepper, and coconut commodities. They analyzed the damage caused by OPT in plantation crops, especially in cocoa, cloves, cashews, pepper, and coconut commodities, and determined alternative solutions for control and prevention. Observations were made in several villages in several sub-districts in Buton Regency. Direct observations were made on the specified land, and interviews with farmers and various related parties were conducted. To get OPT-type data and damage levels. OPT that attacks cashew consists of two types of pests and one disease. The level of damage OPT in the categorized category of guava plants. The level of damage to the pest on the categorized cashew was low. In coconut commodities, found OPT from three types of pest groups, namely Orycter Rhynocheros, Aspidiotus Destructors, and Pestalotia sp. The level of attack of the three pests was categorized as low. Cocoa was the commodity mainly attacked by OPT, consisting of 4 types of pests and four types of diseases. Fruit rot (Phytophthora palmivora) and stem cancer (Phytophthora palmivora) had a heavy attack rate in all cocoa-producing districts in Buton Regency.

Abstract

Cheilomenes sexmaculata (Fabricius) is a potential natural enemy of aphids. Various aspects of the ecology and biology of this predator have been studied; however, there is still limited information on its physiology, particularly regarding pheromones and other semivolatiles. Naturally, intraspecific and interspecific interactions of C. sexmaculata involve a variety of semiochemicals. The information on the semiochemicals of C. sexmaculata, particularly its sex pheromones, footprints, defense mechanisms, aggregation, and other semivolatile characteristics, is still limited in Indonesia. This research was aimed to identify the semiochemical produced by the female of C. sexmaculata. The volatile compounds emitted by C. sexmaculata were captured using the headspace solid-phase micro extraction (SPME) method. The identification and quantification of each volatile compound were analyzed using gas chromatography-mass spectrometry (GC-MS). A total of 47 volatile compounds was identified among the semivolatiles. The identified volatiles comprise 47 compounds, mainly from the hydrocarbon compunds. Methyl isovalerate was the compound with the highest proportion, namely 31.43%. Several compounds identified were known to be components of the C. sexmaculata pheromone, namely methyl isovalerate, limonene, undecane, dodecane, and eicosane. These compounds were reported as components of sex pheromones, aggregation, and alarm. The limonene identified in this experiment was also previously reported in several Coccinelliade as a component of aggregation pheromone.
