Abstract

Paederus fuscipes is an important predators in soybean fields, including toward Helicoverpa armigera. Predation evaluation using a cage are very common, giving significant suppressed the exposed pest population. However, predation evaluation in open space is rarely conducted. This study was to investigate the dispersal capability of P. fuscipes, and to evaluate the effectiveness of the beetle release in the predation on H. Armigera eggs and larvae. Observations were made in a soybean field in Mekarwangi Village, Cianjur, during soybean planting season in 2005 and 2006. In the dispersal study, all beetles were collected from the field and tagged on the elitra. As many as 1187 tagged beetle were released. The dispersal was observed in the area within a radius of 40 m from the release point. In the predation study, eggs and larvae of H.armigera from laboratory rearing were used as the prey. Soybean plots with exposed prey were treated by releasing the beetle with different densities, i. e., 100-400 beetles, and a control. The released beetles were from laboratory rearing and beetles were collected from the field. The study indicated that the tagged beetles that were released to the soybean field actively move but their dispersal were relatively slow. Until 5 days after release, most beetles were remain in the area surrounding release point, within a radius of 5 m. Release of predators to the soybean field, suppressed H. armigera egg and larva populations for both vegetative and generative stages, but were not significantly different between treatment and control plots, except for the egg population on vegetative stage. It indicates that population of the natural predator in soybean field were very complex and potential to be used for controling pest populations. Thus, it is important to manage soybean field that can support the role of predators in the field. Key words: predator release, Paederus fuscipes, predation, Helicoverva armigera

Abstract

Effect of gamma irradiation [60Co] against Bactrocera carambolae Drew & Hancock in vitro and in vivo. Bactrocera carambolae Drew & Hancock is one of the most important pests on guava fruit. According to a quarantine regulation in export-import commodities, irradiation treatment is a suitable methods for eradicating infested organism, which is relatively safe for the environment. The aim of this research was to determine mortality doses and an effective dose of [60Co] gamma ray irradiation for the eradication purpose, and its implication on the survival of fruit fly B. carambolae. Two irradiation methods of in vitro dan in vivo were carried out, by exposing egg and 3rd instar larvae of B. carambolae obtained from the laboratory reared insect. Eleven doses of gamma ray irradiation of 0, 30, 50, 75, 100, 125, 150, 175, 200, 300, 450, and 600 Gy were applied, respectively. The level of 99% fruit fly mortality was estimated by the value of LD99 using probit analysis and the number of larvae, pupae and adult survival were evaluated by analysis of variance (ANOVA), and the means compared by Tukey’s test, at 5% of significance level. These result showed that the effective lethal dose (LD99) of irradiation that could be successful to eradicate eggs and 3rd instar larvae in vitro were 2225 and 2343 Gy and in vivo were 3165 dan 3177 Gy, respectively. Almost all of the treated larvae survived and developed to pupae, therefore only the minimum irradiation dose of 30 Gy allowed the pupae to develop into adults.

Abstract

Linear Trap Barrier System (LTBS) is an innovative control technology developed using a trap system to control the movement of rice field rats. This study aims to determine the catch pattern and catch direction of rice field rats in several phases of rice plant growth. The experiment carried out was the installation of 6 LTBS units in 2 types of rice field rats habitat, i.e., village border and irrigation embankments. LTBS was installed in 3 phases of rice plant growth, i.e., vegetative, early generative, and late generative. The results showed that the installation of LTBS in both habitats had the same catch pattern, i.e., the highest percentage of rat catch occurred in the early generative phase. Likewise, the direction of rat catch in each phase of rice growth also showed the same pattern, i.e., the number of rats caught in the entry trap was relatively the same as the number of rats caught in the exit trap.

Abstract

Reclamation has an important role in the recovery of mined land ecosystems and is expected to restore the diversity of insects such as Coleoptera. Reclamation process can change Coleoptera diversity and formed communities new of functional groups. The objective of this research was to study the diversity, functional role, and composition of the Coleoptera in the reclamation area. This ecological research was conducted in reclamation area of PT. Berau Coal in Binungan, Berau District, East Kalimantan. Several ages of reclamation area were selected for observation i.e. 2, 4, 6, 8 and 10 years and also natural forest as comparison. Insects were sampled using pitfall trap and malaise trap in a 100-meter transects for each age revegetation. The results showed that there is no difference in the diversity of Coleoptera between age of reclamation. Age of reclamation tend to affect the composition species and functional role of Coleoptera. Abundance of predatory Coleoptera show differences in different reclamation ages, while the abundance of other functional group (herbivor  detritivor and mycophagus) does not seen to be influenced by age of reclamation. Nevertheless, there is an increasing trend of Coleoptera abundance of herbivores and detritivor group with increasing age reclamation.

Abstract

Tikus sawah merupakan hama utama tanaman padi yang masa perkembangbiakannya berkaitan dengan fase pertumbuhan tanaman padi. Penelitian ini bertujuan untuk mengetahui nisbah kelamin tikus sawah pada beberapa fase pertumbuhan tanaman padi berdasarkan hasil tangkapan linear trap barrier system (LTBS). Lokasi penelitian merupakan satu hamparan sawah irigasi yang berada di Kebun Percobaan Balai Besar Penelitian Tanaman Padi, Sukamandi, Subang, Jawa Barat. Percobaan yang dilakukan pada penelitian ini adalah pemasangan 3 (tiga) unit LTBS pada habitat tanggul irigasi. Pemasangan LTBS dilakukan selama satu musim tanam yang terbagi atas 3 periode pemasangan, yiatu pada fase vegetatif, awal generatif, dan akhir generatif. LTBS dipasang selama 25 hari pada setiap periode pemasangan, kemudian dipindahkan sejauh ± 200 m. Pengamatan hasil tangkapan LTBS dilakukan setiap hari pada setiap periode pemerangkapan, yaitu pada pagi hari mulai jam 07:00 - 10:00 WIB. Tikus yang tertangkap kemudian diidentifikasi jenis kelaminnya dengan cara mengukur jarak anogenital, yaitu jarak antara area kelamin dengan anus. Tikus jantan umumnya memiliki jarak anogenital yang lebih panjang dibandingkan tikus betina. Hasil penelitian menunjukkan bahwa jumlah tangkapan tikus jantan dan tikus betina pada fase vegetatif relatif sama. Adapun pada fase awal generatif jumlah tangkapan tikus betina relatif tinggi, dan sebaliknya pada fase akhir generatif. Meskipun demikian, fase pertumbuhan tanaman padi tidak berpengaruh terhadap nisbah kelamin tikus sawah karena jumlah tangkapan tikus jantan (136 ekor) dan tikus betina (147 ekor) tidak berbeda signifikan.

Abstract

Parasitoid A. lopezi dintroduksikan ke Indonesia pada 2014 untuk mengendalikan kutu putih asing invasif P. manihoti. A. lopezi berinteraksi dengan predator P. ramburi dan C. montrouzieri pada pertanaman singkong yang terserang kutu putih P. manihoti. Penelitian bertujuan untuk mengkaji pengaruh interferensi kedua predator terhadap keefektifan A. lopezi pada P. manihoti. Percobaan dilakukan di dalam laboratorium dengan menggunakan cawan petri dan kurungan serangga. Nimfa kutu putih instar-3 dipaparkan pada kedua predator selama 24 jam. Pengamatan dilakukan terhadap perilaku parasitoid dan tingkat pemangsaan predator. Kehadiran predator berpengaruh nyata terhadap penurunan masa kunjungan, masa penemuan inang, dan jumlah telur yang berhasil diletakkan oleh A. lopezi pada nimfa kutu putih. Kedua larva predator mampu memangsa kutu putih yang tidak terparasit dan yang terparasit umur 1-8 hari. Predator mampu mendikriminasi kutu putih yang terparasit umur 14 hari (mumi). Pemangsaan predator terjadi pada kutu putih yang terparasit umur 1-, 3-, dan 8- hari. Kombinasi parasitoid dengan kedua predator menunjukkan adanya interaksi antagonis. Kehadiran predator P. ramburi dan C. mountrouzieri menurunkan tingkat parasitisme A. lopezi pada P. manihoti.

Abstract

One of the rice producing regions in Indonesia is South Sulawesi. Wajo Regency is the second highest rice producing area in South Sulawesi, after Bone Regency. Based on the irrigation system, rice cultivation in Wajo Regency consists of technical irrigation, rainfed rice fields, and rice cultivation or dry land. Agriculture with various irrigation systems has an impact on pest population levels and the intensity of attacks. The decline in rice productivity is caused by many factors, one of which is the attack of rice rat pests that occur in several areas in Wajo Regency. There are several techniques and strategies for field rat management, ranging from sanitation, technical culture or plant cultivation, mechanical, biological, and chemical physical. All techniques and strategies of rice rat management must be applied integrated, continuously, and together in one stretch. This study aims to measure the potential presence of rice rats in several irrigation systems in Wajo Regency (irrigation, rainfed rice fields, and dryland rice), analyze the management of rice rats carried out by farmers, and the factors that affect it. The method used is observing rice planting patterns based on irrigation systems, estimating the population level of rice rats with single live traps and the level of attack on several rice planting irrigation systems. Likewise, rice rat population management in several rice planting irrigation systems, data analysis, and economic analysis. The result of this study is that the highest estimate of rats is in dryland rice plantations. The intensity of rat attacks was highest in dry land Pr>F 0.045 the area of attack was highest in rainfed land Pr>F was 0.0171, for intensity and area of attack in generative phase 1. The success of cultivation in dry land was 16.3% in generative phase 1 which was 16.48%. The presence of rats correlates both the intensity of the attack and the area of each addition of rats will increase the intensity of the attack by 0.155% and the area of attack by 0.308%.

Abstract

The most dominant mealybug species found on cassava is Phenacoccus manihoti. Parasitoid Anagyrus lopezi is a biological agent of P. manihoti in many countries. Monitoring the incidence and population of mealybug and the percentage of parasitization were done, as well as the population of ants and predator insects for 12 consecutive months. The highest incidence and attack rate of mealybugs were 26 and 64%, respectively, during the dry season. A. lopezi was able to suppress the population of P. manihoti between 2-17 individuals per plant with a parasitization rate varied from 12 to 46%. Our study showed that the parasitization rate of A. lopezi increased significantly with the increase in mealybug density. Predators P. ramburi and C. montrouzieri were found in low populations and have not had a significant impact on the mealybug population. Our study demonstrated the important role of natural enemies in suppressing the mealybug population on cassava

Abstract

Kutu putih Paracoccus marginatus Williams & Granara de Willink (Hemiptera: Pseudococcidae) merupakan salah satu  hama yang paling dominan pada tanaman singkong (Manihot esculenta). Hama ini pertama kali terdeteksi di Indonesia pada tahun 2008. Parasitoid Acerophagus papayae Noyes & Schauff (Hymenoptera: Encyrtidae) merupakan agens hayati eksotik yang potensial mengendalikan kutu putih di banyak negeri. Penelitian ini bertujuan untuk mengkaji dinamika penekanan populasi P. marginatus oleh musuh alami di lapang. Monitoring dilakukan dengan cara mengamati 50 tanaman contoh setiap bulannya. Peubah yang diamati meliputi insidensi serangan dan populasi kutu putih, persentase parasitasi dan hiperparasitasi serta populasi predator pada tiga kebun singkong selama 12 bulan berturut-turut. Insidensi serangan dan tingkat serangan kutu putih tertinggi masing-masing sebesar 26% dan 64% terjadi pada musim kemarau. Parasitoid A. papayae mampu menekan populasi P. marginatus antara 1-15 ekor per tanaman dengan tingkat parasitisasi 9-16%. Dinamika parasitisasi parasitoid bergantung pada kelimpahan kutu putih di lapangan. Hiperparasitoid yang ditemukan menyerang parasitoid tersebut adalah Chartocerus sp. (Hymenoptera: Signiphoridae) dan Prochiloneurus sp. (Hymenoptera: Encyrtidae). Hiperparasitisasi Chartocerus sp. pada A. papayae berkisar 0.87-1.05%, sedangkan hiperparasitisasi Prochiloneurus sp. pada A. papayae berkisar 0.47-1.35% per tanaman. Predator Plesiochrysa ramburi dan Cryptolaemus montrouzieri sangat rendah populasinya di lapangan sehingga tidak memberikan dampak yang nyata terhadap fluktuasi populasi kutu putih.
