“…On the field 1, the planthoppers population continued to increase with the increasing of the age of the plant up to 70 days ( Figure 1). The results of this study are different from those of Nelly et al (2017) mentioning that the WBP population in vegetative phase plants was higher than the population in generative phase plants. The composition of the stages of the WBP population in every month in the field 2 is presented in Figure 3.…”

“…Predators found can be grouped into generalist predators and specialist predators (Symondson et al, 2002). This finding is different from Nelly et al (2017) who reported that WBP's natural enemies consisted of 5 orders including Insecta and Arachnida classes. The report also found no mirid bugs of Miridae family and rove beetles (genus Paederus, family Staphylinidae) which are specialist predators that are very potential as biological control agents for planthoppers, including WBP in corn.…”

“…These eggs then hatched into nymphs one week later, so the peak of population density of nymph and WBP brachiptera occurred at 31 dap ( Figure 5). Susilo et al (2017) reported that the WBP population in corn plants 40 dap was dominated by nymph and short-winged adults stages, the peak of population occurred at 70 dap and it caused hopperburn on plants at 88 dap, while Nelly et al (2017) reported that the WBP population in corn plants was higher in vegetative phase than in generative phase.…”

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.

“…In Canadian, the corn planthopper, Stenocranus Fieber is recognized by external characters correlated with genitalic organ (Hamilton 2006). Meanwhile, corn planthopper or Stenocranus pacificus Kirkaldy (Hemiptera: Delphacidae) was reported attacking corn in West Sumatra (Nelly et al 2017), it was a pest invasive on corn in the Philippines before (Cayabyab et al 2009). The white waxy substance in the abdomen is characteristic of female (Dumayo et al 2007).…”

Syahrawati M, Nelly N, Hamid H, Efendi S. 2018. Short Communication: Abundance of corn planthopper (Stenocranus pacificus Kirkaldy 1907, Hemiptera: Delphacidae) on five new corn varieties. Biodiversitas 19: 1029-1034. Both local and hybrid corn varieties have been attacked by Stenocranus pacificus or corn planthopper frequently grown in West Sumatra. So, the basic aim of the study is to know about the abundance of S. pacificus on major five corn varieties that will be intermittently released viz., N35, N37, NT10, NT104, and NT105. The study was conducted around palm plantation in Dharmasraya District using Randomized Block Design in 5 replications. The observations were made at weekly intervals throughout the season after planting up to 8 weeks. Number of S. pacificus were collected from 16 hills by using simple aspirator, selected randomly from each unit. The measurement of leaf length, leaf width, stem diameter and trichome length were also performed to confirm the physical effect of S. pacificus preferences. LSD test at 5% level of significance was done to determine the influence of different varieties on insect population. The S. pacificus preferably effect to NT10 variety as compared to other varieties from the early growth of corn, but the S. pacificus abundance was higher at the generative phase than the vegetative. There was a very rapid increase in its population from week to week. Physical factors of the plant, as like as trichome, affected the insect abundance.

Ledakan populasi hama wereng jagungmerupakan fenomena baru di Indonesia khususnya di Provinsi Lampung. Serangan hama ini telah menyebabkan tanaman jagung menjadi puso (hopperburn) dan menyebabkan gagal panen. Penelitian ini bertujuan untuk mengetahui: (1) pengaruh beberapa teknik pengendalian terhadap populasi hama wereng jagung,(2) teknik pengendalian yang efektif dalam menurunkan populasi hama wereng jagung, dan (3) jumlah daun teroviposisi.Penelitian ini dilaksanakan di kebun percobaan di Desa Muara Putih, Kecamatan Natar, Kabupaten Lampung Selatan dan di Laboratorium Hama dan Penyakit Tanaman Fakultas Pertanian, Universitas Lampung. Perlakuan disusun dalam Rancangan Acak Kelompok (RAK) dengan 6 perlakuan, yaitu aplikasi insektisida kimia sintetik klorpirifos + sipermetrin 2 ml/l, aplikasi insektisida kimia sintetik sipermetrin 2 ml/l, aplikasi n insektisida nabati Tithonia diversifolia 3 ml/l, aplikasi cendawan entomopatogen Metarhizium anisopliae 20 g/l, aplikasi pengendalian mekanik perangkap plastik mika bening berperekat ukuran 2,5 m x 0,5 m, dan control dan setiap perlakuan diulang tiga kali. Hasil penelitian menunjukkan bahwa populasi hama wereng jagung yang telah diaplikasikan satu kali dengan kelima jenis teknik pengendalian nyata lebih rendah dibandingkan dengan kontrol pada pengamatan 2, 3, dan 14 HSA (hari setelah aplikasi).Sedangkan pada aplikasi dua kali, kelima aplikasi teknik pengendalian yang diterapkan berpengaruh nyata terhadap populasi hama wereng jagung pada setiap hari pengamatan. Dari seluruh teknik pengendalian, aplikasi insektisida kimia sintetik klorpirifos + sipermetrin dan insektisida kimia sintetik bahan aktif lambda sihalotrin efektif menurunkan populasi hama wereng jagung. Jumlah daun teroviposisi oleh hama wereng sangat berfluktuasi tergantung pada jenisteknik aplikasi dan waktu pengamatan.
