Abstract

The objective research is to know the daily activities and preference of predatory birds Lanius sp. to several stages of Sexava spp. Ten predatory birds 12 to 14 months of age were bought at merchant bird in Yogyakarta. The study was conducted naturally under controlled condition in cages. Before the study was conducted the predatory birds were acclimatized for three days by feeding them cricket and gradually changed to Sexava spp. The young nymphs, old nymphs, adult male, and adult female of Sexava spp. were found at coconut plantation in Dumagin village became the new dietary of the predator. The result showed that Lanius sp. is a diurnal bird; the activities were dominated by hunting and preying (16.52%), followed by flying (6.53%), jumping (5.70%), and walking (4.58%). The Lanius sp. preferred to prey on significantly more nymphs of Sexava spp. than the adult. The birds prey proportionally on the young nymphs, old nymphs, male, and adult females for 50%, 41%, 5%, and 4%, respectively.

Abstract

The chronic, endemic, and outbreak of a longhorn grasshopper (Sexava spp.) occurs at central production of coconut palms in Indonesia, such as North Sulawesi, Maluku, North Maluku, Papua and West Papua. Farmers suffer from very significant economic-losses due to the pest attack, for example in Salibabu Island. Previous study in 2010 at District of Bolaang Mongondow Selatan, Province of North Sulawesi, revealed that the predatory bird Lanius schach is promising for biological control of the pest. In areas of the pest outbreak, the bird is absent, on the other hand, it is abundant in Yogyakarta. As many as 30 males and 10 females of the bird were introduced to Salibabu Island and they were intended to control the pest. All birds were successfully introduced and released at Sub District of Moronge. Within 2 months after release the birds were observed at 5 km away from the release site. Trends on reduction of the pest population-density and leaf damage were observed within 2 months after predator release. Next program on acceleration of the predator increase in numbers is urgently attempted to keep the predator being under controlled within expected period of 3 years. ABSTRAKIntroduksi Burung Predator Lanius schach dari Yogyakarta ke Pulau Salibabu untuk Pengendalian Sexava Spp. pada Tanaman Kelapa Ledakan populasi belalang antena panjang (Sexava spp.) yang kronis dan endemik terjadi pada sentra produksi kelapa di Indonesia, seperti Sulawesi Utara, Maluku, Maluku Utara, Papua dan Papua Barat. Serangan hama ini mengakitkan petani mengalami kerugian ekonomi yang sangat signifikan, misalnya serangan di Pulau Salibabu. Penelitian awal pada tahun 2010 di Kabupaten Bolaang Mongondow Selatan, Provinsi Sulawesi Utara, mengungkapkan bahwa predator burung Lanius schach berpeluang sebagai agens pengendalian hayati hama tersebut. Di daerah ledakan populasi hama, burung ini tidak ada, tetapi, burung tersebut berlimpah di Yogyakarta. Sebanyak 30 jantan dan 10 betina burung berhasil dintroduksi ke Pulau Salibabu. untuk mengendalikan hama tersebut, predator burung Lanius schach telah diintroduksi sebanyak 30 ekor jantan dan 30 ekor betina ke Pulau Salibabu. Predator yang berhasil diintroduksi ini dilepas di Kecamatan Moronge. Dua bulan setelah pelepasan, burung dapat diamati pada jarak 5 km dari lokasi pelepasan. Kepadatan populasi hama dan kerusakan daun cenderung menurun dalam waktu 2 bulan setelah pelepasan predator. Program berikutnya adalah percepatan peningkatan jumlah predator dan diusahakan supaya predator dapat diawasi dalam jangka waktu sekitar 3 tahun.

Abstract

The nettle caterpillars pest Thosea monoloncha (Limacodidae: Lepidoptera) has attacked the coconut plant in Tolonuo Island, North Halmahera district, North Maluku Province with the intensity of attacked varied from light  minor damage to severe damage. This research purpose is to control the population of nettle caterpillars T. monoloncha and the response of farmers to technology using Nucleo Polyhedrosis Virus (NPV). The study was conducted from December 2014 to November 2015. The stages of this study are consisted of (a) observation of pest population T. monoloncha, (b) determination of plant damage intensity and (c) farmerd response to control technology. The results showed that the application of NPV extract can decrease the population of coconut pest T. monoloncha, the intensity of the damage decrease from severe, heavy and moderate to light damage. In additon, it also increase the amount of frond and coconut production from 14 to 45 nuts per tree. Farmers' response to various aspects of technology varied from 63.5-97.5%. ABSTRAKHama ulat api Thosea monoloncha (Limacodidae: Lepidoptera) telah menyerang tanaman kelapa di Pulau Tolonuo, Kabupaten Halmahera Utara, Provinsi Maluku Utara dengan intensitas kerusakan bervariasi dari ringan sampai sangat berat. Penelitian bertujuan untuk mengendalikan populasi hama ulat api T. monoloncha dan respon petani terhadap teknologi pemanfaatan Nucleo Polyhedrosis Virus (NPV). Penelitian dilaksanakan pada bulan Desember 2014 sampai November 2015. Hasil penelitian menunjukkan bahwa aplikasi ekstrak NPV dapat menurunkan populasi hama kelapa T. monoloncha, menurunkan intesitas kerusakan dari kerusakan sangat berat, berat dan sedang menjadi kerusakan ringan, meningkatkan jumlah pelepah dan buah kelapa dari 14 butir menjadi 45 butir per pohon. Respon petani terhadap berbagai aspek teknologi berada pada kisaran 63,5-97,5%.

Abstract

Insect diversity and vegetation structure are two aspects that affect the reproduction of insectivorous birds. The objective of this study was to investigate the characteristics of the original habitat Lanius schach in Tanjungsari of particularly the type, composition of vegetation, and preference to insect sprey. Observation of vegetation and insects were conduct using a combination methods of the track and checkered line on the transect along the 10 km (ten observation points). Insect and tree species were counted on plot (20 m x 20 m), shrub (10 m x 10 m), bush (5 m x 5 m), and grass (2 m x 2 m). Vegetation analysis was used to calculate the structure and composition of vegetation, whereas Shannon diversity index was used for insect diversity. Prey test was conducted to determine the preferences of insectivore birds on insects. The composition of the vegetation species consists of 7 grasses, 20 bushes, 5 shrubs and 18 trees. The dominant species of vegetation based on highest important value index was Tectona grandis, Ipomoea sp., I. cylindrica, and Panicum brevifolium respectively. The highest diversity index of vegetation group were bush (2.430), tree (1.696), grass (1,680), and shrubs (1.364), respectively. Insect diversity index was 2.572 and grasshoppers (Orthoptera) was the most preferred prey by L. schach. Overall, the habitat of insectivore birds L. schach are dominated by T. grandis, and has high diversity of bush.

Abstract

Sexava, the long-horned grasshopper, is an important pest of the coconut palm that destroys leaves and fruits. Study on analysis of damage to leaves and fruits of coconut palms due to being attacked by Sexava was aimed to determine the mechanism of the damage. Visual in situ observations were carried out in Salibabu Island, Talaud Islands Regency, North Sulawesi Province, while histological and chemical analyses of attacked young fruits and observation of symptoms of the secondary disease were carried out in the laboratory. The results showed that the process of damage to coconut-palm leaves and fruits due to bitten by the Sexava occurs mechanically. Phytotoxic symptoms due to bites of the long-horned grasshopper and symptoms of the secondary disease were not observed. Fruit tissue with a thickness of several millimeters appears to dry out and die while the tissue near the wound appears normal. Reduced sugar levels, cellulose, and lignin, between healthy fruit tissues (1.22%, 2.72%, 5.66%) and those attacked (1.22%, 2.85%, 4.84%) were relatively the same. The attacked young-fruits will fall out while attacked fruits on bunches more than 3 months old still keep to grow and develop until ripe.
