Cardiovascular diseases contributed to 353 million disability-adjusted life years globally in 2016, of which 44% were attributed to smoking (Gakidou et al., 2017; Naghavi et al., 2017). Similarly, smoking was among the top contributors to disability-adjusted life years in Indonesia in 2017, particularly among males (Mboi et al., 2018). Smoking prevalence among men (15+ years) is among the highest in the world at 67%, while that among boys (13-14 years) is high at 36.2% (Ministry of Health, 2011; World Health Organization, 2018). The smoke-free policy (SFP), recommended by the Framework Convention on Tobacco Control, has been among the most effective policy against smoking. Previous studies showed that it is associated with reduced smoking rates in the United States, reduced indoor smoking in the United Kingdom, lowered secondhand smoke exposure in New Zealand, reduced myocardial mortality in Belgium, and increased indoor air quality in 15 countries in North America and Europe (
Scale insects (Hemiptera: Sternorryncha: Coccomorpha) are a very important insect group containing numerous pests of woody and herbaceous plants worldwide. The only complete study of any scale insects in Indonesia was by D.J. Williams on the mealybugs (Pseudococcidae sensu lato), published in 2004; the other scale insect families have only been documented in various small publications. Here we provide a complete checklist of the scale insects of Indonesia, which now contains 364 species belonging to 136 genera in 16 families. The family Diaspididae is the most diverse, with 158 species belonging to 44 genera, followed by Pseudococcidae with 105 species belonging to 32 genera, and Coccidae with 65 species belonging to 22 genera. The other families are, in order of size: Monophlebidae (26 species belonging to 9 genera), Rhizoecidae (12 species belonging to 4 genera), Asterolecaniidae (11 species belonging to 5 genera), Leconodiaspidae (7 species belonging to 3 genera), Cerococcidae (5 species belonging to 3 genera), Xenococcidae (5 species belonging to 2 genera), Ortheziidae (4 species belonging to 3 genera), Eriococcidae (4 species belonging to 2 genera), Aclerdidae (2 species belonging to 1 genus), and Kermesidae (1 species belonging to 1 genus).
First report of Begomovirus infection on papaya in Bengkulu, Indonesia. A field survey was conducted during 2019, wefound a severe systemic yellow mosaic, striped green mosaic on leaves petiole, green spots on the fruit of papaya, leafmalformation, and stunting symptoms on three papaya cultivation area in Rejang Lebong, Kepahiang, Bengkulu Tengah, andSeluma, Bengkulu Province, Indonesia. A begomo-like virus was inferred to be the possible cause of the virus-disease-likesymptoms. The study aimed to identify the causal of those typical symptoms on papaya. PCR using universal primer fortranscriptional activator protein (TrAp) and replication-associated protein (Rep) gene of Begomovirus successfully amplifiedthe DNA fragments of 900 bp in all 10 detected samples, except for samples with leaf malformation and stunting symptoms. Itis indicating that those typical symptoms on papaya is associated with Begomovirus infection, while the causal of leafmalformation and stunting is unknown yet. This work is the first report of Begomovirus infected papaya in Indonesia. Severedisease incidence caused by this pathogen was observed on papaya plants in Bengkulu Province that was in the range of 42–100%. This finding is a precious information to be used for identification, and characterization the species of the virus,determining control strategies against the disease.
Natural incidence of entomopathogenic fungus Nomuraea rileyi on Spodoptera frugiperda infesting corn in Bengkulu. Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) is a new invasive pest in corn. The intensive use of synthetic insecticides for pest control causing various problems such as resistance, pest resurgence, and environmental damage. To solve these problems, entomopathogenic fungi could be used as an alternative in pest management. Therefore, this study was aimed to determine the natural incidence of Nomuraea rileyi (Farlow) Samson (Hypocreales: Clavicipitaceae) entomopathogenic fungus on S. frugiperda in Bengkulu. The research was carried out by exploring the corn producing areas in Bengkulu for N. rileyi incidence. The results showed that the N. rileyi was occurred naturally infected S. frugiperda larvae reached 79.0%. Meanwhile, the percentage of crops damage due to S. frugiperda was ranged from 40.0 to 96.0%. The highest natural incidence of N. rileyi were found in the Village of Bukit Barisan and Tugu Rejo (79.0%), followed by Pulo Geto Baru (25.0%), and Taba Mulan (5.3%) while the lowest incidence was in Sidomulyo (1.0%). The infected larvae were not found in the Napal, Beringin Raya 1, and Beringin Raya 2, despite the percentage of S. frugiperda attacks was reached 50.0; 50.0 and 74.0%, respectively.
Usaha sampingan strategis masyarakat seperti ternak unggas dan ikan telah terbukti mampu menopang perekonomian masyarakat desa dan perkotaan, namun kondisi ini mengalami penurunan dan bahkan cendrung ditinggalkan karena terbatasnya sumber pakan alami serta mahalnya harga pakan dampak dari naiknya nilai tukar rupiah dan perubahan iklim yang ekstrim. Salah satu usaha mengatasi permasalah tersebut adalah dengan introduksi pemanfaatan potensi sumberdaya lokal yaitu biokonversi limbah pertanian milik masyarakat desa melalui program Pengabdian pada Masyarakat (PPM). Kegiatan PPM dilakukan dari bulan Juli ̶ Agustus 2019 di Desa Lawang Agung, Kecamatan Air Periukan, Kabupaten Seluma yang merupakan desa binaan Jurusan Perlindungan Tanaman, Fakultas Pertanian, Universitas Bengkulu. Hasil kegiatan PPM ini telah mampu melatih para petani muda usia 18 ̶ 45 tahun dalam memanfaatkan sampah loading ramp pabrik kelapa sawit dan limbah batang jagung untuk media budidaya maggot Hermetia. Meskipun paket teknologi PkM telah diketahui oleh 50% peserta sebelum program dimulai, namun tidak satupun peserta yang pernah mencobanya. Daya serap teknologi dan kemampuan praktek peserta sangatlah tinggi yaitu berurutan mencapai 93% dan 100%. Ketertarikan peserta untuk menerapkan usaha mencapai 80%. Masalah gender ditemukan dalam program penerapan iptek ini yaitu peserta wanita kurang tertarik untuk melanjutkan budidaya maggot Hermetia karena bentuknya yang tidak disukai.
A survey and laboratory experiments were conducted on incidence rates and economic impact of Eucarazzia elegans (Ferrari) (Hemiptera: Aphididae) in Salvia officinalis L. (Lamiaceae). The investigations were purposively performed on conventionally grown common sage in Bornova and Menemen, Izmir-Turkey. Experiments were set up with zero, normal and double population densities of the aphid. The corresponding treatments 0 (no exposure), 2, 4, 6, 8, 10 and 12 weeks (complete exposure) were used for evaluating economic impact. Eucarazzia elegans infested old leaves with an incidence rate of 9.5% in the early spring and then migrated to young leaves and blossom at the beginning of the summer with the incidence rate of 1.1%. The seasonal distribution of the aphid was affected more by temperature than humidity and rainfall. Although the aphid infestation had no differences on the quantity of the essential oil, some of the essential oil components were markedly different from the control. The total plant weights (fresh and dry) with the normal and double infestation rate were decreased about a third and more than a half compared to the control, respectively. Aphids feeding on common sage beyond 8-10 weeks caused more than 50% yield loss. The highest cost-benefit ratio was achieved in plots where six insecticide applications were made.
Common sage, Salvia officinalis L., (Lamiaceae) has been economically cultivated in many countries due to its widely used as food and medicines. The sage's production, however, is still facing significant yield losses because of insect pest attacks including other arthropods. This research is aimed to determine insect pests of S. officinalis and their natural enemies. Insect species were collected in a year 2016 in the sage fields at Bornova and Menemen, Izmir-Turkey. In total 47 species consisted of 18 insect pests and 29 natural enemies belonging to 30 families in 11 insect orders were collected. The species namely Aphis passeriniana (Del Guercio) and Eucarazzia elegans (Ferrari) (Hem.: Aphididae); Dysmicoccus angustifrons (Hall) (Hem.: Pseudococcidae); Eupteryx gyaurdagicus Dlabola and Micantulina (Mulsantina) stigmatipennis (Mulsant & Rey) (Hem: Cicadellidae); Chrysolina (Taeniochrysea) americana (L.) (Col.: Chrysomelidae) and Thrips tabaci Lindeman (Thy.: Thripidae) were determined as key insect pests. M. stigmatipennis (Mulsant & Rey) was a new pest hosting for common sage whilst E. elegans (Ferrari) and D. angustifrons (Hall) were known as the new species recorded for Izmir province. In addition, the natural enemies of key insect pest were determined and discussed.
[EFICATION OF BOTANICAL INSECTICIDE OF Tephrosia vogelii Hook. f. LEAF EXTRACT AGAINTS Crocidolomia pavonana (F.) AND Plutella xylostella (L.) AND ITS EFFECT TO Diadegma semiclausum (Hellen)]. The active fraction of hexane extract of Tephrosia vogelii (Tv) leaves was evaluated for this insecticidal activity on second-instar larvae of Crocidolomia pavonana and Plutella xylostella as well as for the safety to the adults of Diadegma semiclausum parasitoid. Fraction (fr) 2-4 of Tv from column chromatography (CC) had strong insecticidal activity on C. pavonana and P. xylostella. In the test with C. pavonana, the fraction was more active by feeding than by contact. Based on LC 50 at 72 hours since treatment (HST), fr 2-4 CC Tv was 1.8 times more toxic to P. xylostella than to C. pavonana. The fr 2-4 CC Tv showed strong antifeedant effect against C. pavonana larvae. At equal test concentrations, the treatment with fr 2-4 CC Tv caused much lower mortality in D. semiclausum parasitoid adults than in its host larvae, P. xylostella. In contrast, an organophosphate profenofos, included in this study as a positive control, was much more detrimental to D. semiclausum than to P. xylostella. In the semifield experiment, fr 2-4 CC Tv had comparable effect with profenofos and bioinsecticide Bacillus thuringiensis in reducing the population of C. pavonana larvae on broccoli plants.
