Kunci Identifikasi Ordo Thysanoptera pada Tanaman Pangan dan Hortikultura

Thysanoptera is a minute insect. It acts as pest, plant virus vector and predator. In this research, the thrips on crop and horticulture have been collected at Bogor and its surrounding. The result of this research was found 16 specieses which is consist of two suborders, that are Tubulifera and Terebrantia. On this two subordos, there are three families, Phalaeothripide, Aeolothripidae and Thripidae. This research also present an identification key of Thysanoptera which is built from these 16 specieses. The images of thrips characters were captured with digital camera to complete the explanation of identification key.Keywords: horticulture, identification, plant crop, thysanopter

Physic Nut Thrips Diversity

Physic nut (Jatropha curcas L.) is a relatively new agricultural crop commodity in Indonesia. Hence, the thrips associated with this plant are not well recognized. The research objective was to provide information and tool for identification of thrips associated with physic nut. Survey method was conducted in some areas of Java, Madura, and Lombok island. The results showed that 10 species of thrips were found associated with physic nut. They belonged to nine genera and three family i.e. Thripidae, Aeolothripidae and Phlaeothripidae and one unidentified species. The Thripidae species were Selenothrips rubrocintus, Rhipiphorothrips pulchellus, Thrips hawaiiensis, Heliothrips haemorrhoidalis, Zaniothrips ricini and Scolothrips sexmaculatus. The family Aeolothripidae were Franklinothrips vespiformis, F. variegatus and Mymarothrips bicolor; the only one of Phlaeothripidae was Ecacanthothripstibialis. The identification key had been built for all species mentioned above. These thrips can be grouped into herbivore, carnivore, and fungivore

The survey was conducted at 13 sites in the lowlands and 6 sites in the swamp areas. The survey found 22 species of thrips predators in lowlands and 6 six species in swamp areas which are grouped into nine families. Predatory thrips species in the lowlands were Ammoplanus sp., Cheilomenes sexmaculata, Chilocorus melanophthalmus, Chilocorus ruber, Chrysopoda sp., Coccinella repanda

Catatan Baru Hama Penting, Frankliniella Intonsa (Trybom) (Thysanoptera: Thripidae) Pada Tanaman Stroberi Di Desa Alamendah, Kecamatan Rancabali Kabupaten Bandung, Jawa Barat

Strawberry is a new crop in Indonesia, and it has been developed because of its high demands. Thrips is one of the strawberry pest that can reduce quality and quantity strawberry productions. The research was conducted in Alamendah-Rancabali Village, Bandung District from March to August 2012. Thrips species that attack strawberry in Alamendah Village dominated by Frankliniella intonsa (Trybom). Other thrips that were found on plants surround strawberry field is Thrips palmi and Microcephalothrips abdominalis. Both of these thrips are found on tomatoes, potatoes, leek, blackberries, weeds (Amaranthus sp. and Ageratum haustonianum). The complete stadia of F. intonsa were found on strawberry flowers. Population densities in the field were found to be between 1.8 to 2.3 individual/flower. Around 68.4%-82.2% of the fields are are infested with F. intonsa. Based on test of F. intonsa attack ability on strawberry plant, the result shows 43% of fruit that harvested is malformed on tips of fruits. Therefore, F. intonsa is potential to become a important pest of strawberry plant

Identifikasi Kutukebul (Hemiptera: Aleyrodidae) dari Beberapa Tanaman Inang dan Perkembangan Populasinya

oai:ojs.journal.ipb.ac.id:article/5962Whiteflies (Hemiptera: Aleyrodidae) can cause direct and indirect damages on plants, especially vegetables. There is only limited information regarding taxonomy and population dynamic of whiteflies attacking vegetables in Indonesia. This research is conducted to identify species of whitefly collected from chili pepper, tomato, and soybean, and to study their population dynamic. The information gathered from these studies will be useful to support whitefly management in the field. Based on morphology identification of the puparium collected directly from the host plants, there were four species of whitefly identified from chili pepper, tomato, and soybean in Bogor, Cianjur, and Sukabumi, i.e. Bemisia tabaci, Aleurodicus dispersus, Trialeurodes vaporariorum, and Dialeurodes sp. The presence of B. tabaci on chili pepper and tomato was associated with virus infection that causes yellowing and leaf curl disease. This population of B. tabaci tended to increase along with plant growth and generally reached the highest population when the plant was 60-70 days after planting.KEY WORDS: Diversity, whiteflies, population

Thrips parvispinus Karny (Thysanoptera:Thripidae) pada Tanaman Cabai: Perbedaan Karakter Morfologi berdasarkan Ketinggian Tempat

One of the important pests on chilli plants is Thrips parvispinus Karny (Thysanoptera: Thripidae). The presence of the pest is detected ranging from lowlands to highlands. This study was aimed to find out the morphological diversity of T. parvispinus at three different altitudes which include Cirebon ( 1200 m asl). At each level of altitude, it was collected 60 female adults of the thrips and then they were preserved into microscope preparations using Hoyer medium. The observed morphological characters of T. parvispinus were the length of body, the width of head, the width of thorax, the length of wing, and the color of body. The difference in morphological characters of the thrips in all three levels of altitude were analyzed using analysis of variance and Duncan’s multiple range test. The correlation between altitude and body color was analyzed using chi- square test. Results showed that the body length, thoracic width, and wing length of the highland thrips were longer than those of the mid and lowland thrips. The three morphological characters showed significant differences between the mid and lowlands and the highlands, except for the character of head width. Changes in the color of the head, thorax, and abdomen were correlated to the level of the altitude. KEY WORDS: Thrips parvispinus, morphological character, altitude, chilli

Thrips Parvispinus Karny (Thysanoptera: Thripidae) Pada Tanaman Cabai: Perbedaan Karakter Morfologi Pada Tiga Ketinggian Tempat

One of the important pests on chilli plants is Thrips parvispinus Karny (Thysanoptera: Thripidae). The presence of the pest is detected ranging from lowlands to highlands. This study was aimed to find out the morphological diversity of T. parvispinus at three different altitudes which include Cirebon (< 30 m asl), Bogor (300 - 400 m asl), and Cianjur (> 1200 m asl). At each level of altitude, it was collected 60 female adults of the thrips and then they were preserved into microscope preparations using Hoyer medium. The observed morphological characters of T. parvispinus were the length of body, the width of head, the width of thorax, the length of wing, and the color of body. The difference in morphological characters of the thrips in all three levels of altitude were analyzed using analysis of variance and Duncan\u27s multiple range test. The correlation between altitude and body color was analyzed using chi- square test. Results showed that the body length, thoracic width, and wing length of the highland thrips were longer than those of the mid and lowland thrips. The three morphological characters showed significant differences between the mid and lowlands and the highlands, except for the character of head width. Changes in the color of the head, thorax, and abdomen were correlated to the level of the altitude

A taxonomic update of Takahashi’s historic collection of mealybugs (Hemiptera: Pseudococcidae) from Malaysia and Singapore

Dr. Ryoichi Takahashi collected mealybugs (Hemiptera: Coccomorpha: Pseudococcidae) from Peninsular Malaysia and Singapore in 1943–1944, and mounted them in 39 permanent slide mounts using Canada balsam. The slides are deposited in the Department of Agriculture, Kuala Lumpur, Malaysia. The objective of this research was to update the identification of Takahashi’s specimens using recent taxonomic keys. Some preparations on cavity slides were re-mounted to facilitate identification. The re-mounted specimens, and those on the original slides, were re-examined and 12 species were identified. The Takahashi samples of Pseudococcus comstocki (Kuwana) and Rastrococcus mangiferae (Green) are the earliest records of these species from Peninsular Malaysia

NEW INDONESIAN COUNTRY RECORDS AND SPECIES INFORMATION FOR MEALYBUGS (HEMIPTERA PSEUDOCOCCIDAE) IN WIRJATI’S HISTORIC COLLECTION

Between 1955 and 1960, a collection of slide-mounted mealybugs (Hemiptera: Coccomorpha: Pseudococcidae) was prepared by Mrs Wirjati, using samples collected between 1916 and 1960 from a variety of hosts in Indonesia. The collection is a record of which species were established in the country in 1960. The slides, deposited at the Indonesian Ministry of Agriculture in Java, are the earliest material in the national mealybug collection. There are 181 temporary slide mounts of unstained, waxy mealybugs mounted in agar or gum chloral media that have dried out to varying degrees. Specimens were retrieved from 50 representative slides and re-mounted as stained, archival mounts in Canada balsam. The method used to retrieve the specimens from the old mounts is described. The re-mounted specimens were re-identified using up-to-date, published identification keys, resulting in new identities for most of the  specimens. Fifteen species belonging to 12 genera were identified, however specimens from four of the slides  could not be identified beyond genus level. The Wirjati slides of Antonina thaiensis Takahashi, Hordeolicoccus nephelii (Takahashi) and Paraputo corbetti (Takahashi) are new country records. The differences between the fauna in Wirjati’s collection and that found in Indonesia today are discussed
