ABSTRACTIntegration of botanical pesticide and entomopathogenic fungi to control the brown stink bug Riptortus linearis F. (Hemiptera: Alydidae) in soybean. The efficacy of botanical pesticides i.e. Annona squamosa seed powder (ASP) or Jatropha curcas seed powder (JSP) integrated with entomopathogenic fungi, Lecanicillium lecanii to control brown stink bug, Riptortus linearis F. was studied at Muneng Research Station, the Indonesian Legume and Tuber Crops Research Institute (ILETRI) in June up to September 2011. The purpose of the research was to determine the efficacy of integration the natural pesticides i.e, A. squamosa seed powder (ASP) and Jatropha curcas seed powder (JSP) and entomopathogenic fungi L. lecanii to control brown stink bug. The treatments were application of (1) ASP 50 g/l, (2) JSP 50 g/l, (3) ASP 50 g/l + L. lecanii 107/ml, (4) JSP 50 g/l + L. lecanii 107/ml, (5) L. lecanii 107/ml, (6) deltametrin and (7) control (untreated). Application of ASP and JSP combined with L. lecanii decreased the hatched eggs by 84% and 82%, respectively. However, reduction of hactched egg from a single application of ASP and JSP were 56-61% . ASP and JSP combined with L. lecanii reduced both nymphs and adult stink bug population built up and damage (empty pod). Application of ASP and JSP in combination with L. lecanii did not affects the survival of generalist predators such as Paederus sp., Oxyopes sp. and Coccinella sp. as opposed to chemical insecticide that did. The integration of ASP or JSP with entomopthogenic fungi L. lecanii was able to increase the efficacy of brown stink bug control.

Whiteflies are a severe threat to soybean production in the tropics. This study aimed to evaluate the soybean resistance level of the whitefly Bemisia tabaci in controlled and uncontrolled environments that is associated with plant age, damage intensity, and trichome density. The research was conducted under two conditions: non-sprayed (NS) and sprayed (SP). This study used 50 soybean genotypes arranged in a randomized block design with three replicates. The whitefly population was derived from natural infestations. The results showed that the highest wild population of B. tabaci occurred at 40 days after planting (DAP), i.e., 126.08 adults/plant in the NS environment and 22.57 adults/plant in the SP environment. The peak damage intensity occurred at 50 DAP, 20.71% in the NS environment, and 17.15% in the SP environment. In the NS environment, there were six resistant genotypes (including the resistant control G100H), 25 moderate, and 19 susceptible genotypes. In the SP environment, 19 genotypes were resistant, 22 genotypes were moderate, and nine genotypes were susceptible, respectively. Six soybean genotypes showed consistent resistance to B. tabaci in NS and SP environments. The low density of leaf trichomes in soybean may influence the high resistance to B. tabaci. The resistant genotypes identified in this study could be utilized in breeding programs for B. tabaci resistance.

The efficacy of entomopthogenic fungus for Tussock Moth Caterpillars Control. The occurrence of Tussock Moth Caterpillar (TMC) out break reported in some areas in East Java at Probolinggo, Malang, Batu and other districts were worried. The high caterpillar population not only attacking mangos, cherry, and wild watercress, but also migrating to living house before pupation. The available control of these caterpillar is chemical pesticide. However, the chemical will kill the natural enemies and other beneficial insects. A laboratory experiment to study the efficacy of five entomopathogenic fungus against TMC and pupae was conducted at the Entomology Laboratory of Indonesian Legumes and Tuber Crops Research Institute (ILETRI) in April 2011. Our experiment was arranged using completely randomized design (CRD) with three replicates using five entomopthogenic fungus. The efficacy was determined by the mortality of caterpillar/larva and pupae infected by the fungus. Result showed that these five fungus had not effectively kill the caterpillar, as the dense setae in integument acted as a mechanical barrier to fungus infection. The pupal stage was more susceptible to fungus infection. It was found that Paecilomyces fumosoroseus and Lecanicillium lecanii fungus were more effective than Metarhizium anisopliae, Beauveria bassiana and Nomuraea rileyi repectively. These two fungus could kill 90% of pupae and also were easier to be cultured in a wide range of natural media. Therefore P. fumosoroseus and L. lecanii are potentially used as a biological control agent against TMC out break.

Integrated Crop Management to Minimize Scab Disease and Tuber Borer on Sweet Potato in Tidal land

IOP Conference Series Earth and Environmental Science (2020)

Sumartini Yusmani Prayogo

Tidal land in South Kalimantan is quite extensive and very suitable for development of sweet potato commodity. The main obstacle to increase the production of sweetpotato in tidal land is the presence of scab disease (Sphaceloma batatas) and tuber borer (Cylas formicurius). The aim of research was to integrate crop management to decreased scab disease and the tuber borer in tidal land. The research was conducted in Rohan Raya Village, Wanaraya Distric, Barito Koala, South Kalimantan, from March to July 2019. The treatments were plowed and harrowed land, dolomite and organic fertilizer, wedding frequency, mulch width, application of Beauveria bassiana entomopathogenic fungi, and shallot extract. The result showed that the tidal land was endemic to scab disease and tuber borer. By using crop management was able to suppress scab disease and tuber borer compared to conventional systems. Conventional technology was unable to prevent both. Besides, local variety was more susceptible to them than superior variety, Sari in addition, it had high productivity. The yield of Sari with crop management can reached up to 24,15 t ha−1. When sweet potato priced was Rp 3,500 kg−1, the income Rp 84,525,000 ha−1, and the production cost was Rp 23,950,000. So, the B/C ratio was 2.5. Therefore, crop management can be used as an innovation technology. This technology was feasible to be developed and recommended to overcome the constrain of major pest and disease of sweet potato in tidal land South Kalimantan and in other tidal land in Indonesia.

The aim of the research was to determine the physiological characters of various L. lecanii isolates as active materials of bioinsecticide to control pod sucking bug Riptortus linearis egg on soybean. Thirty seven (37) of L. lecanii isolates were collected from four locations of soybean plantation in Indonesia. This study obtained four virulent isolates that were potential as active ingredient of bioinsecticide i.e. Ll-JTM11, Ll-JTM12, Ll-JTM15, and Ll-TB2. Virulent isolates were obtained from insect cadaver isolation in the field, while less virulent isolates were gained from soil. Physiological characters of potential isolates were fast colonization rate of the egg, thick and wholly, high sporulation with large conidial size, high germination rate after 12 hours incubated in the water, up to 95% germ tubes were formed. Clustering of isolates based on the physiology character can determine the fungus virulence, while the grouping based on the source or host location can not select fungal virulence. The virulent isolates had similarity in physiological characters equal to 98%. Therefore, four potential isolates could be used as biological agents in integrated pest mangement program (IPM), especially pod sucking bug R. linearis on soybean.

Pengembangan teknologi pengendalian hama utama kacang hijau menggunakan biopestisida

Jurnal Entomologi Indonesia (2020)

Yusmani Prayogo Marida Santi Yudha Ika Bayu

Hama merupakan salah satu kendala utama dalam upaya peningkatan produksi kacang hijau di Indonesia. Saat ini, pengendalian konvensional menggunakan pestisida sintetik kurang berhasil karena populasi dan kerusakan akibat hama masih tinggi. Penelitian ini bertujuan untuk mengembangkan biopestisida sebagai teknologi pengendalian hama utama kacang hijau yang dibandingkan dengan efikasi pestisida sintetik. Penelitian ini dilaksanakan menggunakan rancangan acak kelompok, lima perlakuan diulang lima kali. Perlakuan yang diuji, yaitu P1: aplikasi serbuk biji mimba (SBM), virus ulat grayak (Virgra) dari Spodoptera litura nuclear polyhedrosis virus, dan konidia cendawan entomopatogen Beauveria bassiana (BeBas) secara preventif; P2: aplikasi SBM, Virgra, dan BeBas berdasarkan ambang ekonomi (AE); P3: aplikasi pestisida sintetik sesuai jadwal; P4: aplikasi pestisida sintetik berdasarkan AE; dan P5: tanpa pengendalian (kontrol). Hasil penelitian menunjukkan bahwa hama yang berkembang adalah ulat grayak (Spodoptera litura (Fabricius)), kutukebul (Bemisia tabaci (Gennadius)), Empoasca sp., Megalurothrips usitatus (Bagnall), kepik coklat (Riptortus linearis (Fabricius)), kepik hijau (Nezara viridula (Linnaeus)), dan hama penggerek polong (Maruca testulalis (Geyer)). Aplikasi biopestisida SBM, Virgra, dan BeBas secara preventif dan aplikasi pestisida sintetik sesuai jadwal efektif menekan populasi hama utama kacang hijau, sedangkan aplikasi biopestisida dan pestisida sintetik berdasarkan AE tidak mampu menekan perkembangan populasi hama utama. Aplikasi biopestisida secara preventif maupun berdasarkan AE lebih aman terhadap kelangsungan hidup musuh alami, sedangkan aplikasi pestisida sintetik dapat membunuh musuh alami yang ada. Biopestisida SBM, Virgra, dan BeBas yang diaplikasikan secara preventif dan terintegrasi berpotensi sebagai inovasi teknologi pengendalian hama utama kacang hijau untuk menggantikan pestisida sintetik.

In the intercropping system between of soybean and citrus plant was known as a triggers of the explosion of whitefly (Bemisia tabaci) and citrus whitefly (Dialeurodes citri) population. These two types of insect pests are in the same order and family which known as an important as vectors for various types of viruses. This study was aimed to identify the morphological characters and efficacy of entomopathogenic fungi that infect B. tabaci and D. citri. Insect cadavers colonized by fungal mycelium were taken from three centers of soybean production in East Java Province (Banyuwangi, Jember, and Pasuruan Regencies). Each insect cadaver from the field was sterilized using 0.5% chlorox solution and then incubated in potato dextrose agar medium. The growing colonies were identified based on morphological characters and then tested by Koch's postulates against B. tabaci. The results of the identification showed that there were Aschersonia aleyrodis Webber fungi obtained with white colony color which then turned into light brown. The size of conidiophores was 39–40×2.1–2.3 µm, conidia 10–11×2.0 µm, optimum temperature 27–30°C, toxic to egg, nymph, and imago, especially isolates from Banyuwangi Regency with mortality reaching 89% within 3–4 days after application. The finding of A. aleyrodis fungal isolates is a new innovation in biological control because both B. tabaci and D. citri are tolerant to synthetic pesticides due to biotype changes.
