Abstract

ABSTRAK. Burik merupakan salah satu penyebab rendahnya mutu buah manggis di Indonesia. Saat ini informasi tentang kejadian burik pada buah manggis di Indonesia baik penyebab maupun pengelolaannya  masih sangat terbatas. Tujuan penelitian ialah untuk mempelajari burik buah, dinamika populasi trips, dan hubungan populasi trips dengan kejadian burik pada buah manggis. Penelitian tentang asosiasi serangga trips (Thysanoptera: Thripidae) dengan bunga dan buah serta hubungannya dengan kejadian burik pada buah manggis dilaksanakan di Desa Cengal, Kecamatan Leuwiliang, Kabupaten Bogor, Jawa Barat dari bulan Mei 2009 sampai dengan Agustus 2010. Pengamatan laboratorium dilakukan di Laboratorium Biosistematika Serangga dan Laboratorium Anatomi Tumbuhan, Institut  Pertanian  Bogor.  Bagian tanaman yang diamati ialah daun muda, kuncup, bunga mekar sempurna, dan buah umur 1–16 minggu setelah antesis (MSA).  Hasil penelitian menunjukkan burik hanya merusak lapisan kutikula dan eksokarp buah manggis. Scirtothrips dorsalis dan Thrips hawaiiensis (Thysanoptera: Thripidae) ditemukan pada daun muda, kuncup, bunga, dan buah manggis. Populasi imago S. dorsalis dan T. hawaiiensis tertinggi ialah 1,15 dan 0,95 indiividu/bunga mekar sempurna, populasi larva tertinggi ditemui pada buah berumur 2 MSA yaitu 8,75 individu. Populasi trips semakin menurun dengan bertambahnya umur buah manggis. Gejala burik paling banyak  muncul pada buah umur 2 dan 3 MSA. Terdapat korelasi antara kepadatan populasi trips pada buah umur 2 dan 3 MSA dengan kejadian burik pada buah manggis. Kepadatan trips sebanyak 10,6 inidividu dapat menimbulkan gejala burik pada buah manggis umur 2 MSA. Karena populasi trips dan gejala burik muncul pada awal pertumbuhan buah, tindakan preventif dengan insektisida dapat dilakukan sebelum tanaman manggis memasuki periode berbunga.ABSTRACT. Fardedi, Maryana, N, Manuwoto, S and Poerwanto, R 2012. Thrips (Thysanoptera: Thripidae) in Flower and Fruit of Mangosteen (Garcinia mangostana L.) and the Correlation to Fruit Scars. Scars on mangosteen decreases the quality of this fruit economically. At the moment, information about management and causal factor of the scars on mangosteen in Indonesia are very limited. The aims of this research were to investigate the fruit scars, the population dynamic of thrips, and the correlation to the fruit scars. The association between thrips and mangosteen flowers and fruits as well as the correlation between thrips population to the fruit scars was investigated. The research was conducted at Cengal Village, Bogor District, West Java from May 2009 to August 2010. Laboratory investigation was carried out in Insect Biosystematics Laboratory and Plant Anatomy Laboratory, Bogor Agricultural University. Parts of plant observed were the shoot, flower bud, opened-flower, and fruit of 1 - 16 weeks after anthesis (WAA). The scars occurred in fruit cuticle and exocarp. There were two species of thrips, Scirtothrips dorsalis and Thrips hawaiiensis, that were found at flower bud, opened- flower, and fruit. The highest larva population of S. dorsalis  and T. hawaiiensis imago were 1.15 and 0.95 each flowers, the highest larva population was on 2 WAA fruits (8.75). The population of adults for both species was high in opened-flower. The population of larva was also high on fruit 2 WAA. The population of thrips decreased along with fruit growth. Scars occurred on fruit 2 and 3 WAA. There was a correlation between the abundance of thrips on fruit 2–3 WAA and scars at mangosteen fruits. Trips density 10.6 could cause scars on 2 WAA fruits. Thrips population and the symptoms of scars occurred on the early growth of fruits, therefore to control the trips using insecticide was suggested to be applied before flowering stage.

Abstract

Diversity of parasitoid and predator arthropod in oil palm and paddy field at Cindali, Bogor Regency. Biodiversity can be defined as the diversity of living things in various places to the riches on earth. Insects as one of the components of biodiversity have an important role in the food web as herbivores, carnivores (parasitoids and predators), and detritivores. The research aimed to study the diversity of parasitoids and predators at two sampling locations. Sampling was carried out at the oil palm plantation PTPN VIII Cindali, Ranca Bungur, Bogor and at the paddy fields that adjacent to the plantation. This research was conducted in December 2014 until July 2015. This research takes 3 plots in oil palm plantations and 3 plots in paddy field. Each plot consists of 5 subplots, one of each was 18 x 18 m. Sampling was carried out following the paddy age, since 2 week after plantation until paddy harvested and repeated every 2 weeks. This research use three methods, i.e. insect nets, pitfall trap and yellow pan trap. The results showed that the diversity of parasitoids and predators on both planting locations was high. In the oil palm plantations the total number of insect parasitoids and predators was 184 morphospecies from 10 orders and 57 families, while in the paddy fields was 183 morphospecies from 10 orders and 60 families. Telenomus podisi parasitoids and predators Anoplolepis gracilipes is morphospecies with the highest abundance.

Abstract

Diversity of parasitic Hymenoptera in different ecosystem types in Central Bangka, Bangka-Belitung Islands.Hymenoptera richness is dominated by parasitic species. More than 80% of Hymenoptera play a role as parasitoid on arthropods that are mostly insects. Diversity of parasitic Hymenoptera is widely studied in various types of terrestrial ecosystems including agro-ecosystem and non-agro-ecosystem. This study aimed to invent and compare the diversity of parasitic Hymenoptera in three different ecosystems, i.e., forest, oil palm plantation, and ex-tin mining. The location was located in Central Bangka Regency, Bangka Island. The study was conducted in Juli 2014 until October 2015. Parasitic Hymenoptera was collected with insect sweep net and yellow pan trap on one transect line with 1000 m length. Parasitic Hymenoptera were found on forest as much as 732 morphospecies, 326 morphospecies on oil palm plantations, and 293 morphospecies on ex-tin mining. Diversity and abundance of parasitic Hymenoptera on forest was higher than oil palm plantation and ex-tin mining area. Braconidae family was found dominant on forest, however on oil palm plantation and extin mining area the dominant family was Scelionidae.

Abstract

Diversity of parasitic Hymenoptera in PTPN VIII oil palm plantation Cindali, Bogor. One group of important natural enemies in oil palm plantation is parasitic Hymenoptera. The purpose of this research is to know the diversity and fluctuation of parasitic Hymenoptera PTPN VIII Cindali oil palm plantation. This research was conducted in 6 blocks of oil palm in September 2014 – June 2015. There were 5 plots in every observation blocks 39.2 x 39.2 m in size, and used direct and indirect method. Direct method done by 5 plants in every plots was taken randomized to observed and taken the herbivore insects to reared until the parasitic Hymenoptera came out. Observation of cover crops conducted by 3 subplots determined diagonally in every plots 9.8 x 9.8 m in size and herbivore insects was observed and collected. Indirect methods used sweep net and yellow pan trap. The result of this research, 26 parasitic Hymenoptera families was found, with the Braconidae was the most morphospecies found and the most individual amount was Scelionidae. The abundance of parasitoid in every month fluctuated.

Abstract

Leafminer fly, Liriomyza spp. are widely known as new important pests attacking many vegetable species inhigh land in Indonesia. The objective of the research was to study community of parasitoid leafminer in highaltitude, and parasitization level. This research also looked at more specific on parasitization level caused byOpius chromatomyiae. There were four species of leafminer recorded from the survey, Liriomyza huidobrensis,Liriomyza sativae, Liriomyza chinensis and Chromatomyia horticola. The observation also found eight species ofparasitioid associated with collected leafminers. Six species of recorded parasitoid belonged to family of Eulopidae,and two rest species belonged to Braconidae and Eucoilidae respectively. Those eight species of parasitoids wereHemiptarsenus varicornis, Asecodes deluchii, Neochrysocharis okazakii, Neochrysocharis formosa ,Neocrhysocharis sp. Quadrastichus liriomyzae, Opius chromatomyaie, Gronotoma micromorpha. ParasitoidOpius chromatomyiae and Hemiptarsenus varicornis were found to be dominant in the range altitude between1001-1300 and 1301-1600 asl. From 16 spesies of hosts attacked by leaf miners, only Opius chromatomyiae wasrecorded to have ability to parasitize the leafminer in 13 host species with parasitization level reached 1,84–62,26%.

Abstract

Blood disease bacterium (BDB) is one of the important diseases in banana and a major obstacle in developing and increasing banana production in Indonesia. The purpose of this study was to prove the ability of the Drosophilidae insect as a vector in transmitting BDB. The research was conducted at the Insect Biosystematics Laboratory and Plant Bacteriology Laboratory, Department of Plant Protection, Faculty of Agriculture, IPB University. Drosophilidae insects were taken from the field and then reared in laboratory by being fed with ripe bananas to obtain offspring that are free from diseases or pathogens. Imago of the Drosophilidae from rearing was fed by inoculum sources which was infected banana, then inoculated into healthy plants. The plants used were healthy and flowering, heliconia. The results showed that the Drosophilidae insects were able to transmit BDB to heliconia plants that showed symptoms, brownish flower colors and falling flower crowns. Detection of BDB isolated from flower parts and the inside parts of the insects used in transmission test using the PCR method showed positive results.
