Abstract

Spodoptera frugiperda J. E. Smith (Lepidoptera: Noctuidae) is a new pest in maize cropping inIndonesia. These insects originated in the Americas and have spread to several countries and causecrop loss in corn. Beginning in 2019, this pest has reportedly attacked corn plants in the Sumatraregion. This activity aims to find out the existence of S. frugiperda in the area of Petir Village,Dramaga Sub-District, Bogor District. The survey results show that S. frugiperda has attacked thecorn crop in Petir Village. Specific characters found in S. frugiperda are inverted "Y" in the headcapsule and a black dot pattern on the abdomen (point four and trapezoid). S. frugiperda larvae found in the village of Petir attack the corn growing point, but the population is still low. Entropathogenicfungi are bioinsecticides that can be used to control pests. Metarizhium rileyi is an entomopathogenicfungus that has the potential to control S. frugiperda in maize. The results indicated that M. rileyi waseasily propagated en masse in agar medium and in good virulence in S. frugiperda.

Abstract

The yellow stem borer, Scirpophaga incertulas (Walker) is a major nocturnal pest of rice. Presence of S. incertulas moth had a flight peak during the lunar period and affects its reproductive status. The purpose of this study was to analyze the critical time in the lunar period related to the highest reproductive status of S. incertulas in the field. Monitoring of moth populations were carried out by setting up two traps equipped with 60-watt LED lights (800 lm) on farmers’s fields in Rawamerta District, Karawang Regency, West Java. Moth trapping was carried out once an hour, started 6–10 PM, for three days on lunar period. The observation were conducted during the nursery, maximum tillering, and grain filling phases. upen capture, females were transferred to rearing cages until they laid all their eggs. Moth reproductive status, fecundity, and fertility were counted and analyzed. Total of captured female S. incertulas moths in the lunar period from three phases of rice was 216 individuals. In the nursery phase, the highest population level was obtained at 8 PM at 27.8%, While the maximum tillering and grain filling phase were 39.3 and 29.1% at 7 PM. The highest population level of virgin, mating, and post-oviposition moths was obtained at 7 PM, at 10,94, 12,52, and 9,64%. The highest average fecundity occurred at 6 PM with 42 eggs/group and the highest fertility was 45,8% at 8 PM. The highest critical reproductive time of female S. incertulas moths occured between 6–8 PM.

Abstract

Rice stem borers (RSB) cause the same damage symptoms and occur through the season and time. During the off-season for rice, these stem borers are not well-known. The research aims to determine the effect of fallowing rice on the presence of rice stem borers and their parasitoids, the potential for RSB infestation, and their parasitoid on subsequent rice seedlings in nurseries at Karawang Regency, West Java. Several variables are observed, including the number of rice stem borer larvae on stubbles, egg masses, the percentage of parasitized eggs, and the number of adults of rice stem borer in nurseries. The results show that species of rice stem borer on the fallow rice are Scirpophaga incertulas and Sesamia inferens. The population of S. incertulas is significantly higher on long rice fallow. The height of the paddy stubble at the two locations is not very different. However, the infested stubble in the short fallow period is higher than those in the long fallow. Eggs of S. incertulas whose high percentage hatched and parasitized, are primarily found in nurseries of areas with long fallow. There are three species of parasitoids identified.

Abstract

Asparagus merupakan tanaman dari golongan hortikultura yang memiliki nilai ekonomi tinggi pada kancah global maupun nasional. Tanaman asparagus di Indonesia merupakan jenis varietas dari hasil introduksi negara yang berada di kawasan subtropis, hal ini menyebabkan pertumbuhan tanaman asparagus tidak dapat optimal di Indonesia. Selain itu, kondisi suhu dan kelembaban yang tinggi di Indonesia menyebabkan tanaman asparagus rentan terserang oleh penyakit dan hama. Desa Cigunungsari belum lama melakukan budidaya tanaman asparagus sehingga banyak masalah yang terjadi. Ulat grayak (Spodoptera litura) adalah hama utama yang menyerang asparagus di Desa Cigunungsari sehingga mengakibatkan adanya penurunan pada jumlah panen serta kualitas asparagus, sehingga diperlukan upaya untuk dapat mengatasi masalah tersebut. Upaya yang dilakukan yaitu melakukan sosialisasi pestisida nabati dari limbah kulit bawang merah kepada masyarakat Desa Cigunungsari. Ulat grayak memiliki sifat yang polifag sehingga memungkinkan untuk menyerang tanaman lain. Pembuatan pestisida nabati cukup mudah dilakukan, yakni merendam kulit bawang dengan toples berisi air. Rendaman tersebut kemudian ditutup rapat dan difermentasi selama 48 jam sebelum diaplikasikan. Pestisida nabati ini masih belum dapat dinyatakan efektif untuk mengendalikan hama ulat grayak. Stadia telur merupakan stadia yang dilaporkan petani berhasil dikendalikan serta pestisida ini bersifat repelen bagi semut.

Abstract

Fipronil merupakan insektisida yang banyak digunakan dalam pengendalian hama wereng batang cokelat (WBC) (Nilaparvata lugens Stal.) di Indonesia. Penggunaan fipronil di tingkat petani seringkali tidak sesuai anjuran sehingga menimbulkan kekhawatiran terjadinya resurjensi. Penelitian ini bertujuan untuk mengkaji pengaruh konsentrasi subletal dan frekuensi aplikasi insektisida fipronil terhadap peningkatan populasi WBC pada dua varietas padi, yaitu IR64 dan Ciherang. Sampel WBC yang digunakan berasal dari Kabupaten Karawang, Jawa Barat. Penelitian terdiri atas uji toksisitas untuk menentukan konsentrasi subletal fipronil, yaitu pada tingkat LC15, LC25, dan LC40, air sebagai kontrol. Masing-masing perlakuan diaplikasikan sebanyak 1, 2, dan 3 kali dengan selang waktu 5 hari antar aplikasi. Hasil penelitian menunjukkan bahwa paparan konsentrasi subletal (LC15, LC25, dan LC40) memicu fenomena hormoligosis yang ditandai dengan peningkatan signifikan pada persentase penetasan telur di semua tingkat konsentrasi dibandingkan dengan kontrol. Persentase penetasan telur tertinggi terdapat pada perlakuan LC15  dengan varietas Ciherang, yakni 82,55%. Meskipun peningkatan konsentrasi dan frekuensi aplikasi (1–3 kali) secara linear meningkatkan mortalitas nimfa hingga 94,44% pada perlakuan LC40, namun pada dosis rendah LC15, peningkatan frekuensi aplikasi justru menstimulasi lonjakan populasi nimfa F1. Populasi nimfa tertinggi terdapat pada varietas Ciherang dengan perlakuan LC15 dua kali aplikasi, yakni 1197,33 individu. Temuan ini mengonfirmasi bahwa aplikasi fipronil pada tingkat subletal, terutama pada varietas rentan, tidak hanya gagal mengendalikan WBC tetapi justru memicu resurjensi melalui peningkatan keberhasilan penetasan telur dan stimulasi reproduksi generasi berikutnya.

Abstract

The potential of forest-derived actinomycetes from Indonesian national parks for managing bacterial leaf blight (BLB) remains largely unexplored. This study aimed to evaluate the biocontrol potential of forest-derived actinomycetes from Kutai National Park against Xanthomonas oryzae pv. oryzae and to assess their ability to promote rice seed germination, seedling vigor, and root colonization. A total of 12 actinomycete isolates were screened for in vitro antagonism against Xoo race 8. Further investigation in planta revealed that 3 isolates (KrK1K1, DrK1T20, and DrK1T21) significantly reduced disease severity by 77.77%, 86.74%, and 82.85%, respectively. Molecular identification of the 3 potential isolates revealed that KrK1K1, DrK1T20, and DrK1T21 are identified as Streptomyces parvulus, Tsukamurella tyrosinosolvens, and Salinispora tropica, respectively. Three selected isolates also significantly (p < 0.05) enhanced the seed germination rate (25.05%) and the vigor index (51.11%). Filtrate bioassays at 5%, 10%, and 15% concentrations demonstrated that only T. tyrosinosolvens DrK1T20 effectively inhibited Xoo growth. All 3 isolates produced siderophores and chitinase, whereas phosphate-solubilizing activity was detected only in S. parvulus. Scanning electron microscopy confirmed effective colonization of rice roots by actinomycetes, indicating a successful interaction between the roots and the actinomycete isolates. These abilities strongly support the potential of forest-derived actinomycetes to control BLB and improve plant growth in the field.
