Abstract

Tipe hemosit serangga telah banyak digambarkan, namun pengklasifikasian secara komperhensif masih sulit untuk dilakukan karena setiap individu serangga memiliki bentuk yang sangat berbeda pada berbagai kondisi. Secara umum tipe hemosit seranga dikelompokkan ke dalam enam jenis utama. Sel-sel itu adalah: prohemosit, plasmatosit, granulosit (yang mungkin sama seperti sistosit atau koagulosit), sel-sel spherule (spherulosit), oenositoid dan adipohemosit. Berdasarkan hal tersebut maka tujuan dilakukan penelitian ini adalah untuk mengetahui tipe sel hemosit larva serangga Trigona sp yang telah dilaporkan berperan sebagai vektor penyebab penyakit darah pada tanaman pisang. Penelitian dilaksanakan di Laboratorium Uji Hayati Serangga, Sekolah Ilmu dan Teknologi Hayati, Institut Teknologi Bandung. Hemolimf diambil dari pembuluh darah pada bagian punggung menggunakan jarum yang halus (Haemotokrit-Kapillaren). Kemudian sampel hemolimf diteteskan pada kaca objek yang telah diberi larutan turk. Untuk penghitungan total hemosit (Total Hemocytes Count (THC)) dihitung menggunakan mikroskop cahaya (pembesaran 40 X). Hasil identifikasi menunjukkan bahwa larva Trigona sp memiliki 5 jenis hemosit, yaitu : Plasmatosit, Prohemosit, Oenositoid, Sel sperul dan Granulosit. Berdasarkan penelitian dapat disimpulkan bahwa terdapat lima jenis tipe hemosit larva serangga Trigona sp, yaitu : plasmatosit, prohemosit, oenositoid, sel sperul dan granulosit.

Abstract

Fruits and vegetables are examples of commodities that are widely traded in people's markets because they are one of the basic needs of the community. The presence of fruit fly attacks on fruits and vegetables traded in public markets is one of the causes for the low quality of these commodities. Information about fruit fly infestations in horticultural commodities traded in public markets is still limited. The purpose of this study was to obtain information related to the ability of fruit flies to invest in commodities that are traded in the people's markets in the city of Kefamenanu. The research was conducted using a survey method and taking several types of traded commodities, the stages of maintenance and identification were carried out in the Biology Education laboratory of the University of Timor from July 2020 to September 2020. The results showed that there were five species of fruit flies that attacked several types of horticultural commodities traded in public markets, namely Bactrocera dorsalis which attacked cayenne pepper, curly chili, large chili, star fruit, guava and tomato. Bactrocera carambolae attacks star fruit. Bactrocera albistrigata attacks curly peppers, cayenne pepper and guava. While Bactrocera passiflorae attacks guava. From the results of this study, important information was obtained that fruit fly pests not only attack horticultural crops in agricultural areas, but can also attack horticultural commodities that have been harvested and traded in the people's markets in Kefamenanu City.

Abstract

Soil insects play an important role in the ecosystem, namely in the process of weathering organic matter and their presence and activities have a positive effect on the physical and chemical properties of the soil. Soil insects will break down organic matter and then release it back into the soil in the form of organic matter which is available to green plants and can be an indicator of soil fertility. This study aims to determine the diversity of ground-surface insects in horticultural farming in Maubeli Village, Kota Kefamenanu District, North Central Timor Regency. The research was conducted from January to March 2021. Samples were taken using the Pitfall Trap. Data analysis was carried out using a quantitative method, namely conducting data collection activities, analyzing the data and then identifying it down to the species level. The results showed that there were 633 individual insects belonging to 7 genera, 6 families and 4 orders. The entire insect order found was Hymenoptera, Coleoptera, Orthoptera, and Blattaria.

Abstract

Black Soldier Fly (BSF) is an insect that reduces organic waste by utilizing its larvae which will extract energy and nutrients from vegetable waste such as mustard and cassava leaves waste, fruits, food scraps, animal carcasses, and feces as food ingredients. This study aimed to see the effectiveness of BSF larvae in reducing feed organic waste of chicory and cassava leaves. The method used in this research is a laboratory and experimental scale experiment. The results of this study showed that the effectiveness of BSF larvae in reducing organic waste feed on cassava leaf waste samples was 57% for 1x3 feeding frequency, but decreased in 1x1 feeding frequency, which was 40%. While the percentage value of sample reduction by BSF larvae in chicory samples was 53% for 1x3 feeding frequency, but experienced a decrease in 1x1 feeding frequency, which was 38%. The effectiveness level of BSF larvae in reducing waste samples can be said to be effective at 1x3 feeding frequency.

Abstract

Trigona sp merupakan salah satu serangga pengunjung bunga pisang yang berperan sebagai vektor penyebar penyakit darah (blood disease) pada tanaman pisang yang disebabkan oleh bakteri blood disease bacterium. Interaksi Trigona sp dan blood disease bacterium dapat memicu aktifnya sistem pertahanan humoral tubuh serangga tersebut. Aktifnya respon humoral Trigona sp ditandai dengan sintesis enzim phenoloksidase (PO) dan sintesis peptida antibakteri (AMP). Tujuan penelitian untuk mengukur respon humoral serangga Trigona sp setelah terinfeksi patogen penyebab penyakit darah. Sistem pertahanan humoral serangga Trigona sp diukur dengan melihat aktifitas enzim PO dan sintesis peptida antibakteri (AMP). Infeksi BDB dilakukan secara oral infeksi dengan jumlah sel bakteri yang berbeda dan lama infeksi divariasikan yaitu 0 (kontrol), 4, 8, 12 dan 24 jam. Hasil penelitian, lama infeksi 4 jam jumlah PO yang dihasilkan yaitu 0,19 unit/mg protein pada infeksi jumlah sel bakteri 19 x 109/ml . Lama infeksi 8 jam, jumlah PO yang dihasilkan sebanyak 0,33 unit/ mg protein pada infeksi jumlah sel bakteri 14. 8 x 109/ml. Lama infeksi 12 jam, jumlah PO yang dihasilkan yaitu 0,18 unit/mg protein pada infeksi dengan jumlah sel bakteri 9.5 x 109/ml. Lama infeksi 24 jam, PO yang dihasilkan yaitu 0,25 unit/mg protein pada infeksi dengan jumlah sel bakteri 14.2 x 109/ml. Uji aktifitas menunjukkan daya hambat sebesar 1,9 cm.
