Abstract

This study examines the potential for rearing Apis cerana Fabricius honey bees in Taman Kehati Kiarapayung, West Java. Observations were conducted by installing 39 beehive in various locations and observing the flora that serve as bee food sources. A total of 50 plant species from 24 families were identified as bee food sources. Out of the 39 beehive, only 4 were successfully inhabited by bee colonies, showing a success rate of 10.3%. The observed colony growth ranged from 3 to 9 honey combs per hive. The main challenges in cultivation are the decrease in food availability during the dry season with very low rainfall, and pest disturbances such as wax moths (Galleria mellonella), wasps (Vespa sp.), and ants (Formicidae). The results of this study indicate that A. cerana beekeeping has the potential to be implemented in specific locations with sufficient food availability and effective pest management. This potential can serve as an additional source of income for the local community and support environmental conservation efforts by utilizing biological resources and biodiversity in a non-destructive manner at conservation sites.

Abstract

Female Aedes aegypti (Linnaeus) mosquitoes bearing Wolbachia are reported to have behavioral changes during mating and blood-sucking. The ovary ecdysteroidogenic hormone (OEH) is a hormone released when female mosquitoes consume blood so that it influencing egg formation. Initial studies regarding the genetics of the A. aegypti mosquito carrying Wolbachia are very necessary to able to do this help control dengue vectors. The polymerase chain reaction (PCR) method is an appropriate method for genetic studies. Primer design is an initial and crucial stage in genetic studies because designing specific primers will determine the success of the PCR process. This research includes several stages of in silico primer design to design OEH gene primers and test the optimization of the in vitro designed primers. The in silico stage which involves primer design, primer BLAST, primer quality testing, and in silico PCR simulations. The designed primers were tested in vitro by performing PCR using various variations in primer concentration (0.2 µM and 0.4 µM) and annealing temperature (start from 45 oC to 60 oC). The results obtained in silico were two pairs of primers: primers OEH 8 and OEH 9. The results of the in silico test obtained a DNA product size of 264 bp for Primer OEH 8 and 236 bp for primer OEH 9, and the PCR efficiency was 95%. The results of the in vitro test showed only primer OEH 9 met the primer criteria according to the in silico test: primer concentration of 0.4 µM with an annealing temperature of 57 oC.

Abstract

Mulberry (Morus sp.) is the primary feed for silkworms (Bombyx mori L.) and determines cocoon quality. However, limited land availability and seasonal changes pose challenges for a consistent mulberry leaf supply, prompting research into alternative feeds. This study aimed to evaluate the effects of alternative feeds on the growth of B. mori, including the length and width of silkworms, the number of live and dead silkworms, and the feed consumption of silkworms. A total of 500 silkworms were divided into six treatments with three replicates each. The treatments were mulberry leaves (K), castor leaves (P1), cassava leaves (P2), broiler chicken feed (P3), castor and mulberry leaves combination (P4), cassava and mulberry leaves combination (P5), broiler chicken feed and mulberry leaves combination (P6). Combined feeds were given at a 1:1 ratio. The results confirmed that B. mori exclusively feeds on mulberry leaves, as no silkworms survived  on P1, P2, or P3 treatments. All combination feed treatments (P4, P5, P6) showed that silkworm growth results were not significantly different from the control treatment (K). Therefore, we recommend using all combination feeds as an alternative feed in B. mori cultivation. However, the best combination feed treatment was shown by P6 with the highest silkworm length and width (3.69 cm; 0.57 cm) and the highest feed consumption (44.16 grams), and P5 with the highest percentage of survival rate (75%) and the lowest percentage of death rate (25%).

Abstract

The fall armyworm (Spodoptera frugiperda Smith) is an invasive pest of corn crops in Indonesia. The development of S. frugiperda rearing techniques based on artificial feed is important to support various research projects on this species. This study aims to study the growth and development of S. frugiperda using soybean-based artificial feed (Glycine max L.). The study utilized first-instar larvae of S. frugiperda adults obtained from the Rasau Jaya Village Corn Farm. A total of 800 larvae were used to obtain accurate and representative data on the insect’s development. The variables observed included several important aspects, such as the survival rate at each stage (from larva to adult), growth morphometry at the sixth instar larva and pupa stages to understand changes in body size and shape, the duration of each stage to determine the length of each developmental phase, and the sex ratio to determine the proportion of males and females in the population. The survival rate data of S. frugiperda imagoes obtained were then analyzed using Microsoft Excel 2013 and presented descriptively to provide a clear and detailed overview of the research results. The research results showed that the survival rate of S. frugiperda at each growth stage averaged above 75%. The lifespan of the larval stage was 12.80 ± 1.00 days, the pupal stage was 7.80 ± 0.77 days, and the female imago (9.55 ± 2.42 days), while the male (7.39 ± 1.77 days). The sex ratio of males to females is 1:1.02. These results indicate the excellent potential of soybean-based artificial feed as the primary diet for maintaining S. frugiperda in the laboratory.

Abstract

Stingless bees (Tetragonula laeviceps Smith) play a crucial role as pollinators in agricultural ecosystems, but their populations are increasingly threatened by synthetic insecticide uses. This study aimed to evaluate the effects of five insecticides on T. laeviceps through topical, residual, and oral applications, both individually and in combination with the adjuvant Agristik 400 L (AG). The tested insecticides included indoxacarb, chlorfenapyr, indoxacarb + chlorfenapyr, flupyradifurone, and abamectin + acetamiprid. The results showed that all insecticides caused 100% mortality at the recommended concentrations. Flupyradifurone had the lowest LC50 values (0.35 ppm for topical application, 0.73 ppm for residual, and 0.94 ppm for oral), indicating the highest toxicity compared to other insecticides. The addition of adjuvants significantly increased insecticide toxicity, especially in residual and oral applications. Unwise insecticide use poses a serious risk to pollinator populations and agricultural ecosystems. Therefore, insecticide application should consider plant flowering phases to minimize its impact on bees, and sustainable pest management strategies should be promoted to ensure environmental balance and agricultural productivity.

Abstract

The infestation of Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae) results in the reduction of flour weight, changes in flour color, and a musty odor in stored materials. One alternative control method is using patchouli extract (Pogostemon cablin), which has insecticidal activity. The extraction methods and the application techniques in controlling storage pests influence the effectiveness of the extract as a botanical insecticide. The study aims to examine the differences in yield, composition, content, toxicity, and repellency levels of patchouli extracts obtained using various extraction methods for controlling T. castaneum. The study employs three patchouli extraction methods: maceration, steam-water distillation, and ultrasonic extraction. Three application techniques are used in this study: fumigation, topical and residue. The observed variables include the content and composition of the extraction yield, toxicity levels, and repellency levels. Data analysis is performed using probit analysis to determine LD/LC50 and LD/LC95, and ANOVA at 5% level, followed by Tukey’s test. The research results indicate that the extraction method assisted by ultrasonic waves yields the highest extraction yield. However, patchouli extract obtained through the distillation method exhibits the highest toxicity effects when applied with topical and residue techniques. The LC50 and LC95  values of patchouli extract obtained via distillation are 0.804% and 1.541% while the LD50 and LD95 values are 49.140 μg/imago and 135.729 μg/imago. The main compounds found in patchouli extract obtained through distillation are patchouli alcohol, α-guaiene, δ-guaiene, and seychellene. Patchouli extract obtained through distillation has the potential to act as a contact insecticide and repellent against T. castaneum.

Abstract

The citrus red mite Panonychus citri (McGregor) is a major pest that can reduce the quality and yield of citrus crops. However, information regarding the local and landscape factors that influence its population dynamics remains limited. This study aimed to analyse the influence of local and landscape factors on citrus red mite population density. The research was conducted in nine citrus orchards in Malang, East Java, Indonesia. Data collected included local factors (pesticide application frequency and plant canopy density) and landscape factors (landscape composition, encompassing the number of patches (NP) and class area (CA) of semi-natural habitats). Pesticide application frequency data were obtained through farmer interviews, while canopy density was measured using a photographic method and analysed with ImageJ2 software. Landscape composition data were by digitizing land-use types within a 500-meter radius of the plot center using QGIS software and subsequently analysed using LecoS (QGIS add-ins) to obtain the NP and CA of semi-natural habitats. The generalized linear  model (GLM) analysis indicated no overall significant influence of both local and landscape factors on P. citri population density. However, it was found that the variation in mite population density was significantly influenced by citrus plant canopy density. These findings suggest that local factors, particularly the canopy microhabitat conditions, are more critical in affecting the P. citri population compared to landscape factors. Therefore, the management strategy for citrus red mite should be focused on the local, on-farm scale.

Abstract

Anagyrus lopezi (De Santis) (Hymenoptera: Encyrtidae) is a specific parasitoid that plays an important role in the biological control of the cassava mealybug Phenacoccus manihoti Matile-Ferrero (Hemiptera: Pseudococcidae). Successful large-scale biological control requires the availability of this parasitoid in sufficient quantities through optimal and efficient mass production. This study aims to develop a mass production model for A. lopezi, taking into account mass rearing methods and the economic aspects of mass production. The experiment consisted of four treatments, namely 3, 6, 9, and 12 cassava cuttings of Manggu variety aged 2 weeks per cage measuring 75 cm × 50 cm × 50 cm. Each cutting was infested with 120 third-instar P. manihoti nymphs and four 2-day-old female A. lopezi obtained from laboratory rearing. Increasing the number of cuttings had a significant effect on the number of mummies produced, with the highest production achieved in the 9-cutting treatment (742.2 ± 12.21 mealybug mummies). The sex ratio of parasitoid progeny (1:2.21) was dominated by females, accounting for 68.91%. The production cost estimation included tools, materials, and labor wages. The total production cost per cage was IDR 48,425, with a cost per mummy of IDR 65. These findings provide technical and economic foundations for developing efficient and sustainable mass production systems of A. lopezi to support P. manihoti biological control programs in cassava plantations.

Abstract

Tritrophic interactions refer to interactions among three trophic levels within a community (producers, herbivores, and carnivores). In oil palm ecosystems, these three trophic levels consist of (1) vegetations, (2) Lepidopterans as herbivores, and (3) Hymenopterans and some of Dipterans as carnivores. Vegetation complexity often influences trophic levels within the food web. This study aimed to investigate the influence of tree island in oil palm plantation on tritrophic interaction, parasitism and abundance of natural enemies. The research was conducted in oil palm plantations which had been enriched with several tree species to form tree islands. Six tree species Peronema canescens, Shorea leprosula, Dyera polyphylla, Parkia speciosa, Archidendron pauciflorum, and Durio zibethinus  were planted in different combinations within  plots of various sizes (5 m × 5 m, 10 m × 10 m, 20 m × 20 m, and 40 m × 40 m). There were three enrichment combinations within the tree islands, i.e., one plant species, six plant species, and control (without enrichment). The results showed that adding tree species in oil palm plantations influenced herbivore species richness and increased the presence of generalist parasitoids. The parasitism rate of Lepidoptera pests was affected by the tree species planted but not by the number of tree species. Parasitoid abundance was not affected by the number of tree species. Overall, this study indicated that the tree islands might increase the complexity of food webs; however,it was not necessarily followed with increased parasitoid abundance nor functional role in oil palm plantations.

Abstract

Pitcher plants Nepenthes spp. are insectivorous plants capable of trapping and digesting insects as an additional nutrient sources. Research on insects trapped in the pitchers of Nepenthes plants has been conducted in several regions of Indonesia. Unfortunately, similar research has never been reported in the Southwest Aceh region. This study aims to analyze the diversity and composition of insects trapped in the pitchers of Nepenthes plants in Gunung Samarinda Village, Southwest Aceh, Aceh, Indonesia. The research was conducted using the exploratory method with purposive sampling from January to July 2024, along the path leading to the oil palm plantation. Insect samples were collected from every Nepenthes plant found at the research location and were identified to the species level. The results showed that a total of 1,740 individuals, belonging to 18 species, 12 families, and 6 insect orders, were found in the Nepenthes pitchers. The three most dominant insect species were Aedes aegypti (Linnaeus) (36.21%), Tetramorium marginatum Forel (16.90%), and Anoplolepis gracilipes Smith (13.33%). The highest insect diversity was found in pitcher of  Nepenthes rafflesiana, followed by N. gracilis, and N. ampullaria. However, there was no significant difference in insect composition among the Nepenthes species. These findings indicate that Nepenthes spp. at the research site function as natural traps for insects, with a dominance of certain species. The presence of Nepenthes in its habitat can play a role in the ecosystem balance, particularly in the interaction between insectivorous plants and insect communities.
