Abstract

The White-Bellied Planthopper (Hemiptera: Delphacidae) Infesting Corn Plants in South Lampung, Indonesia. Corn plants in South Lampung were infested by newly-found delphacid planthoppers. The planthopper specimens were collected from heavily-infested corn fields in Natar area, South Lampung. We identified the specimens as the white-bellied planthopper Stenocranus pacificus Kirkaldy (Hemiptera: Delphacidae), and reported their field population abundance.

Abstract

The Population of White-Bellied Planthoppers and their Natural Enemies: the New Pest of Corn in Lampung. The white-bellied planthoppers (Stenocranus pasificus), hereinafter referred to as WBP, as new exotic pests in Lampung have the poten-tial to reduce corn production and threaten national food sovereignty. Therefore, population of the pest needs to be managed to prevent the outbreaks. However, there is still limited information on the bio-ecology of WBP. Thus, this research was conducted to: 1) study the population growth pattern of WBP on various corn cultivars and 2) document the natural enemies of WBP. This research was carried out from May to December 2017with a survey method on several corn fields in South Lampung and planting trial on an experimental field of Faculty of Agriculture, Universitas Lampung planted with 3 corn cultivars, i.e. Madura, P-27 and NK which were arranged in randomized complete block design with three replications. The results of the research showed: 1) there were two peaks of population density observed during plant growth. The peak of adult stage of macroptera population density occurred at 17 and 53 days after planting (dap), the highest number of leaves with oviposition mass was observed at 24 and 65 dap, while the peak of population density of nymph stage and adult stage of brachiptera occurred at 31 and 75 dap; 2) Natural enemies of WBP included 9 orders, classified as specialist predators of mirid bugs (Cyrtorhynus) and rove beetles (Paederus), and generalist predators of spiders (Araneae) and lady beetles (Coccinellidae). The population of specialist predators was fluctuated depending on WBP population, while the population of generalist predators was varied.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh aplikasi ekstrak daun sirih (Piper betle L.) dan batang brotowali (Tinospora sp.) terhadap mortalitas dan perkembangan serangga uji jangkrik (Gryllus mitratus) di laboratorium.  Penelitian disusun dalam rancangan acak lengkap (RAL), yang terdiri dari 5 perlakuan dan 5 ulangan dengan P0 (kontrol) tanpa aplikasi ekstrak pestisida nabati, P1 aplikasi ekstrak daun sirih konsentrasi 5%, P2 aplikasi ekstrak daun sirih konsentrasi 10%, P3 aplikasi ekstrak batang brotowali konsentrasi 5%, dan P4 aplikasi ekstrak batang brotowali konsentrasi 10%. Hasil penelitian menunjukkan bahwa aplikasi ekstrak daun sirih konsentrasi 5% dan 10%  menyebabkan mortalitas jangkrik sebesar 76% pada pengamatan 15 hsa (hari setelah aplikasi).  Sedangkan aplikasi ekstrak batang brotowali konsentrasi 5% menyebabkan mortalitas jangkrik sebesar 86%, dan aplikasi ekstrak batang brotowali konsentrasi 10% menyebabkan mortalitas serangga uji jangkrik sebesar 74% pada pengamatan 15 hsa.  Aplikasi ekstrak daun sirih dan batang brotowali secara nyata mempengaruhi perkembangan jangkrik, sehingga nimfa yang berhasil menjadi imago tidak lebih dari 20%.

Abstract

Hama kutu putih pepaya Paracoccus marginatus Williams & Granara de Willink merupakan salah satu hama yang merusak tanaman, terutama tanaman pepaya. Tujuan penelitian ini adalah untuk mengetahui beberapa variabel peneluran dan perkembangan P. marginatus Williams & Granara de Willink pada tiga jenis inang tanaman pangan yaitu kedelai, singkong dan jagung. Penelitian ini dilaksanakan pada bulan September 2022 hingga Februari 2023 di Laboratorium Ilmu Hama Tumbuhan dan Laboratorium Lapang Terpadu Fakultas Pertanian Universitas Lampung. Percobaan ini dilakukan dengan tiga macam perlakuan (kedelai, singkong dan jagung) yang disusun dalam Rancangan Acak Lengkap (RAL) dengan enam ulangan. Hasil penelitian menunjukan bahwa tanaman kedelai, singkong dan jagung berpengaruh terhadap peneluran dan  perkembangan kutu  putih papaya P. marginatus  berbagai instar nimfa sampai lama hidup kecuali terhadap pupa P. marginatus. Jumlah telur menetas P. marginatus dalam satu ovisac pada tanaman kedelai, singkong dan jagung antara 135 hingga 350 butir dengan rata-ratanya secara berturutan adalah 213,67; 308,33; 180,33 butir serta persentase telur menetasnya secara berturutan adalah 80,88;  86,49; dan 78,14 butir per ovisac. Lama hidup fase telur sampai imago serangga betina 32,7 ± 0,4 hari pada kedelai; 35,5 ± 0,4 hari pada singkong; dan 30,0 ± 0,4 hari pada jagung sedangkan pada serangga jantan 27,2 ± 0,9 hari pada kedelai; 31,2 ± 0,8 hari pada singkong; dan 24,2 ± 0,6 hari pada jagung.

Abstract

Maize is an important commodity as a source of food, feed and industry. The presence of pests can reduce productivity and cob quality. This study aims to determine the various types of pests that attack corn cobs and their level of attack on several varieties of corn. The survey was conducted in four districts of corn production centers in Lampung: East Lampung, South Lampung, Pesawaran, and Pringsewu. Two fields were taken from each district as sampling sites. Identification was conducted at the Plant Pest Science Laboratory, Faculty of Agriculture, University of Lampung. The results showed that aphids were the pest with the highest population density in Pringsewu, Pesawaran, and East Lampung Districts, which were 17.3 individuals per plot, 35.6 individuals per plot, and 23.8 individuals per plot, respectively. Powder beetles had the highest population density in South Lampung District at 15.1 individuals per plot. The highest damage intensity was found in Bisi 99 and Bisi 79 varieties caused by armyworms, which amounted to 4.18% and 4.30%.
