Abstract

Upaya pengendalian hama tanaman tebu (Saccharumofficinarum) dapat dilakukan dengan memanfaatkanagensi hayati seperti parasitoid telur Trichogramma chilonis. Perbanyakan T. chilonis di laboratorium umumnya menggunakan telur Corcyra cephalonicasebagai inang sebagai inang belum optimal dikarenakan  belum diketahui potensi produksi optimal parasitoid tersebut. Akan tetapi, faktor jumlah pias telur inang dan lama penyinaran ultraviolet (UV) diduga mempengaruhi hasil produksi parasitoid. Penelitian ini bertujuan untuk mengetahui pengaruh jumlah pias C. cephalonica dan lama penyinaran UV terhadap kualitas biakan T. chilonis di laboratorium.Penelitian ini menggunakan Rancangan Acak Lengkap(RAL) 2 faktor yaitu Jumlah pias inang dan lama penyinaran UV diulang sebanyak 3 kali sehinggadiperoleh kombinasi perlakuan sebanyak 27 unit. Hasil menunjukkan bahwa faktor jumlah pias dan lama penyinaran UV berpengaruh nyata terhadap daya parasitasi, kemunculan imago, dan nisbah kelamin, namun tidak terdapat interaksi antar keduanya. Jumlah pias 3 dan lama penyinaran UV 60 menitmenghasilkan kualitas biakan terbaik dan dapat direkomendasikan untuk perbanyakan massal T. chilonis. Jumlah pias dan lama penyinaran UV Optimal dapat meningkatkan hasil  produksiparasitoid.

Abstract

Background: Corn is an important commodity in Tulungagung Regency; however, infestations of Spodoptera frugiperda have caused substantial yield losses, particularly during the vegetative growth stage, with reported damage levels reaching 20–70% depending on infestation intensity. Understanding the population density and spatial distribution of this pest under local agroecosystem conditions is therefore essential for developing effective control strategies. This study aimed to analyze the population density, distribution pattern, and environmental relationships of S. frugiperda on corn plants in the hilly area of Tanggunggunung, Tulungagung Regency. Methodology: The research was conducted on corn plants aged 15 to 45 days post-planting at two distinct locations: Ngrejo Village (approximately 110 meters above sea level) and Jengglungharjo Village (approximately 145 meters above sea level), each encompassing an area of 25 square meters. A two-dimensional sampling method was employed, utilizing 10 fixed observation plots per field, with observations occurring every three days. The variables observed included pest population density, symptoms of pest attack, and abiotic environmental factors such as temperature and humidity. Distribution patterns were analyzed using the Morisita index and the degree of Morisita (Ip), while the relationships between pest populations and environmental factors were examined through Pearson’s correlation analysis. Findings: The population of S. frugiperda in Ngrejo village exhibited a random distribution pattern (Id= 1.016; Ip= 0.004), whereas in Jengglungharjo village, it demonstrated a tendency towards clustering (Id = 0.211; Ip= 0.456). The density of the pest population showed a strong positive correlation with temperature (r= 0.799 to 0.702) and a negative correlation with humidity (r= −0.661 to −0.423). Contribution: Microclimatic conditions play a key role in shaping the spatial distribution and population density of S. frugiperda, highlighting the importance of site-specific, ecology-based pest management to improve corn productivity in hilly agroecosystems

Abstract

This study aimed to analyze the influence of abiotic factors on the diversity of natural enemies in cocoa fields. The study was conducted from January to March 2025. Various traps were used, including yellow traps, light traps, pitfall traps, and visual observations. Identification showed that cocoa fields with misting applications had a higher number of natural enemies (1,052 individuals) compared without misting fields (658 individuals). The application of misting resulted in higher diversity indices (H'), richness (R'), and dominance (C'), as well as lower evenness (E') compared to untreated fields. These findings suggest that the misting system creates a more favorable microhabitat for natural enemy diversity, thus potentially strengthening the IPM approach in cocoa cultivation. Interestingly, the analysis showed that temperature had a significance value (sig) > 0.05, indicating that temperature did not show a significant correlation with the increase in the abundance of natural enemies, while humidity has a significance value (sig) < 0.05, which shows that humidity has a significant correlation, although statistically relatively small, with the increase in the abundance of natural enemies.

Abstract

This study aims to characterize the pesticide compounds in garlic (Allium sativum L.) extract nanoparticles and test their mortality effectiveness against armyworms (Spodoptera litura F.) in the laboratory. Nanoparticle synthesis was carried out using the ionic gelation method with chitosan-TPP, which was subsequently characterized using PSA, SEM, FT-IR, and GC-MS. The characterization results showed a particle size of 930.52 nm with a homogeneous distribution (PDI 0.147). GC-MS analysis successfully identified the main bioactive organosulfur compounds, namely diallyl disulfide (20.72%), diallyl trisulfide (14.16%), and diallyl tetrasulfide (5.79%). Bioactivity testing using the sandwich method at five concentration variations (0-1%) showed the highest mortality reaching 70% at a 1% concentration. Probit analysis yielded values of LC₅₀ 1.116% and LC₉₀ 1.720%, as well as LT₅₀ 5.117 days and LT₉₀ 9.893 days. Statistical test results indicated a significant difference (p<0.05) between all treatments and the control group. Thus, it can be concluded that the garlic extract nanoparticle formulation has the potential to be an effective nano-bioinsecticide, with a mode of action that is dose-dependent and time-dependent in controlling S. litura larvae.
