Abstract

The gall fly Cecidochares connexa (L.) (Diptera: Tephritidae) was introduced in Bantimurung, Polewali Mandar Regency,  South Sulawesi in 1999, to control the Siam weed Chromolaena odorata, an invasive weed from Florida, United States. However, some previous studies have shown that C. connexa can be attacked by local predators and parasitoids, which can affect the effectiveness of C. connexa in the field. The objective of the research is to study the new interaction and association between  the introduced C. connexa, and local parasitoids. The research was conducted in April-December 2021 at two habitats namely open fields and cocoa plantations, in four villages of Polewali Mandar Regency. Purposive sampling was conducted to collect C. odorata infested by the gall flies. Thirty C. odorata samples were collected from three different sites at each habitat and each village. The galls were grouped into two different categories i.e. those with and with out holes. The galls with holes were then reared until the insects emerged and the insect specimens were identified. The research results showed that the gall numbers, healthy and parasitized C. connexa at opened areas were significantly higher as compared to cocoa plantations. Parasitism phenomenon indicated the new interaction and association between the C. connexa with the local parasitoids. The parasitization rate of C. connexa in the opened fields (23.24%) was not significantly with in the cocoa plantations (28.84%). On the parasitized C. connexa were found four families of parasitoids i.e. Eulophidae, Braconidae, Eupelmidae, and Ormyridae. The dominant parasitoid found was Quadrastichus sp.1, with the parasitization rate of 14% in open fields and 10% in cocoa plantations.

Abstract

Spodoptera frugiperda Smith is a major pest of corn plants. Information on the life cycle and survival of this pest is important for proper and effective control. This study was conducted to determine the life cycle and survival of S. frugiperda in several areas in West Java. This study was conducted from June to August 2020. Samples were taken from several areas divided into three categories: highlands in Lembang District (1,100 m asl), middlelands in Jatinangor District (858 m asl), and the lowlands in Tarikolot District (103 m asl). Sampling used the observation method to study the effect of differences in altitude on population, life cycle, and survival. The results showed that there was no significant difference in the development time of S. frugiperda among the three different areas. The average development time of S. fugiperda was 24.55 days (highlands), 24.36 days (middlelands), and 24.07 days (lowlands). The survival percentage of S. frugiperda from highland, middle, and lowland areas in the egg phase was 95.44%, 97.34%, and 96.89%, larval phase 98.46%, 98.65%, and 98.48%, and pupal phase 87.63%, 88.08%, and 93.43%. The sex ratio of S. frugiperda from the highlands was 1:1, from the middlelands was 1:1.28, and from the lowlands was 1:0.89. Location did not affect the width parameter of the head capsule in S. frugiperda. Based on the test results, it is known that the life cycle, survival, and sex ratio of S. frugiperda from several regions do not have significant differences.

Abstract

The major royal jelly protein 2 (mrjp2) gene is one of the molecular markers that can discriminate between Apis cerana Fabricius and A. mellifera Linnaeus. Due to the lack of mrjp2 gene sequences registered in GenBank for Indonesian A. cerana and A. mellifera, DNA characterization and bioinformatics analysis were needed. This research aimed to characterize the exon-intron organization of mrjp2 genes for both Indonesian bee species and analyze the phylogenetic relationship with other mrjp family genes. DNA samples of Apis cerana and A. mellifera, collected from Bogor, were amplified using MF-MR primer at annealing temperatures of 47 oC and 50 oC, respectively. The length of A. cerana and A. mellifera DNA sequences were 579 and 597 bp, respectively. The DNA sequences of both species were comprised of partial exons 1, introns 1, exons 2, introns 2, and partial exon 3. The number of putative amino acids of A. cerana and A. mellifera mrjp2 genes were 111 and 123, respectively. We confirmed that the partial MRJP2 putative amino acids of both honey bees belong to the MRJP family and contained the peptide signal in the 14 first amino acid sites. Nucleotide variation of the mrjp2 gene in A. cerana was higher than A. mellifera. Phylogenetic tree construction showed that A. cerana and A. mellifera form a monophyletic clade with the A. mellifera mrjp7 gene and another mrjp family gene clustered as reported in a previous study.

Abstract

The cabbage crop caterpillar, Crocidolomia pavonana, that can be very damaging to Brassicaceae plants in Indonesia, particularly in the Cianjur Regency. Farmers in the area have been using synthetic insecticides like emamectin benzoate to control this pest, but it seems that continuous use of these insecticides can lead to resistance in the pest. This research aimed to determine the level of resistance and distribution of emamectin benzoate in C. pavonana in Cianjur Regency. Field populations of C. pavonana were collected from five villages in three districts in Cianjur Regency. As a comparison, a laboratory population was used to determine the resistance ratio. All populations were tested for toxicity to determine the LC50. The results showed that populations of C. pavonana from Cianjur Regency were still susceptible to emamectin benzoate. Treatment at 22.08 í— 10-4 mg a.i/l concentration in 72 hours after treatment showed that the population's mortality was >90%. The resistance ratios of C. pavonana in Cianjur Regency were quite concerning (resistance indocation), with a range of 1.33–2.01 indicating resistance to emamectin benzoate was moderate. Interestingly, the Sindang Jaya population showed the highest resistance ratio. It's worth noting that over 90% of farmers in the region use this insecticide in the field, which supports the idea of resistance to the chemical. This study provided valuable insight into the distribution of insecticide used and resistance levels of C. pavonana in the area support each other.

Abstract

Black soldier flies (Hermetia illucens (Linnaeus)) or BSF are insects that process organic waste, with larvae rich in nutrients and potential as an alternative protein source for food and feed. Astaxanthin, an antioxidant found in plants, algae, and crustaceans, is also assumed to be present in insects like BSF. This study examined the impact of feeding different organic wastes on BSF larval growth and astaxanthin content in its pupae. The experimental design involved four treatments: fruit and vegetable scraps (BS), tofu pulp (AT), rice leftovers (N), and a mix of fruit and vegetable scraps, tofu pulp and rice left-over (C), with animal feed T51 as control. Each treatment was repeated three times. Growth parameters of BSF such as weight, length, and larval characteristics, along with the chemical content of pupae, including astaxanthin, were measured. Pupae were extracted using a triphasic maceration method with n-heptane, ethyl acetate, acetonitrile, butanol-l, and distilled water. Compound identification was done using terpenoid qualitative tests, thin layer chromatography (TLC), and liquid chromatography-mass spectrometry (LC-MS). The findings revealed that fruit and vegetable scraps (BS) significantly increased larval body size, with a weight of 0.09 ± 0.04 grams/larvae and a length of 1.49 ± 0.31 cm/larvae. LC-MS analysis detected lutein derivatives, anisodamine, resveratrol derivatives, dehydroarginine, and astaxanthin derivatives with a molecular mass of 597.23 m/z in BSF larvae fed on fruit and vegetable scraps.

Abstract

Helopeltis bradyi, merupakan salah satu hama perkebunan teh yang menyebabkan kerusakan hingga penurunan hasil produksi tanaman. Cendawan Lecanicillium lecanii sebagai musuh alami merupakan pengendalian alternatif yang telah diteliti untuk menekan perkembangan dan populasi H. bradyi. Penelitian bertujuan mengetahui patogenesitas blastospora dan konidia terhadap mortalitas, serta dampaknya terhadap kemampuan makan dan reproduksi H. bradyi. Penelitian menggunakan rancangan acak lengkap dengan sepuluh perlakuan dan lima ulangan, termasuk kontrol positif (insektisida deltametrin), kontrol negatif (akuades), serta konsentrasi blastospora (2,45 × 106 hingga 2,45 × 109 blastospora/ml) dan konidia (2,78 × 106 hingga 2,78 × 109 konidia/ml) L. lecanii. Hasil penelitian menunjukkan bahwa L. lecanii dengan konsentrasi 2,78 × 109 konidia/ml menyebabkan kematian H. bradyi sebesar 86% dan rata-rata 223,89 tusukan pada 7 hari setelah aplikasi. LC50 dan LT50 konidia L. lecanii lebih rendah, yaitu 6,62 × 105 konidia/ml dan 4,44 hari dibandingkan dengan blastospora, yaitu 2,20 × 107 blastospora/ml dan 5,37 hari. Aplikasi L. lecanii dengan konsentrasi 2,45 × 109 blastospora/ml menghasilkan jumlah telur terendah, yaitu 5,40 butir. Blastospora maupun konidia L. lecanii terbukti efektif dalam mengendalikan H. bradyi. Konidia memberikan hasil terbaik dalam mortalitas dan pengurangan aktivitas makan nimfa instar III, sementara blastospora juga efektif meskipun dengan hasil yang sedikit lebih rendah. Hasil penelitian ini menunjukkan L. lecanii dapat menjadi alternatif pengendalian hama yang ramah lingkungan dan berkelanjutan dibandingkan insektisida sintetik.

Abstract

Pollination is important in cashew production, thus it is important to understand the factor determining the presence of pollination in cashew habitat. The research was carried out by field surveys in cashew farms to record the insects that exhibited nectar and pollen foraging activities on wild and cashew flowers. This study recorded the similarity between flower-insect visitors on wild plants and cashews, namely families of Apidae, Halictidae, Pieridae, and Andrenidae. Apidae were the most important flower visitors, but the honey bee, Apis sp. as an important pollinator, did not show the highest abundance. Wild flowering plants in cashew fields have the potential to play a role in the conservation of cashew pollinators.

Abstract

Stingless bees are spread across several islands in Indonesia, including Sulawesi. There have been no reports of daily activity of stingless bees in West Sulawesi Province. Therefore, this study aims to identify types of stingless bees in West Sulawesi, measure their daily activities, and their relationship with environmental parameters. The research was conducted in the highlands (Taupe Village, Mamasa Regency, 1,340 m dpl) and the lowlands (Mirring Village, Polewali Mandar Regency, 63 m dpl). Daily activity data collected which includes the activities in and out of the nest, carrying pollen, and throwing away rubbish. Daily activity observations use the scan sampling method. The results of the research show that the type of bee in Taupe Village is Wallacetrigona incisa (Sakagami & Inoue), while in Mirring Village is Tetragonula sapiens (Cockerell). There was no significant difference in the daily activity of W. incisa in the highlands and T. sapiens in the lowlands (P > 0.05). Significant differences were seen between the activities of leaving and entering the nest and the activities of carrying pollen and throwing away rubbish (P < 0.05). Wind speed is an environmental parameter that influences pollen-carrying activity in T. sapiens in the lowlands (r = 0.83; P = 0.002). Environmental parameters greatly influenced the daily activity of W. incisa at 12.00 pm, with an influence of 93% (P < 0.05). The results of this study indicate that differences in the type and habitat of bees and environmental factors cause differences in the daily activity of stingless bees.

Abstract

The almond moth Cadra cautella (Walker) is a notable stored product pest which can cause detrimental loss on stored cocoa. Cocoa can be stored in bean and powder forms. The information about survival and development of C. cautella on stored cocoa is limited. This research aimed to determine the effect of cocoa powder and cocoa bean in the storage against the survival and development of C. cautella. This research was conducted in Plant Pests Laboratory, Department of Plant Pests and Diseases, Faculty of Agriculture, Universitas Brawijaya. This research consisted of two treatments namely cocoa bean and cocoa powder with no choice method and repeated six times. The observed variables were number of larvae, pupae, male and female almond moth of F1 progeny, and developmental time of this insect. The t-test analysis was applied to determine the treatment effect. Results showed that the number of larvae, pupae, adult males and females of F1 progeny cultured on cocoa powder were significantly higher than on cocoa bean. The total developmental time and life cycle of almond moth were shorter on cocoa powder than on cocoa bean. Therefore, to store cocoa in powder form is riskier to the almond moth infestation rather than in bean form. Hence, it is suggested to take more concern on the cocoa powder storage better in order to minimize the almond moth infestation.

Abstract

The diversity of arthropod communities is often used as a bioindicator of environmental changes, specifically in coffee farms with various management systems. Significant impacts of the environmental changes lead to alterations in the community structure and function of arthropods. The aim of this research was to determine the diversity and ecological roles of insect and arachnids in arabica coffee plantations in Bandung Regency. Sampling was conducted on five plots measuring 100 m2 each, with a separating distance of 50 m, in coffee farms located in Legok Nyenang Village, Bandung Regency. This was performed five times per weekly intervals using sweep nets, yellow tray traps, and beating sheets. Subsequently, collected samples were identified based on morphological characters at the Pest Laboratory, Faculty of Agriculture, Padjadjaran University. A total of 269 insects species (11 orders and 98 families, total 669 individuals) and 23 species of Arachnida (one order and 13 families, total 44 individuals) were found, The most abundance of natural enemies were the parasitoid, Megacampsomeris prismatica (Hymenoptera: Scoliidae) and the predator, Tetragnatha sp. (Araneae: Tetragnathidae). Meanwhile, the ecological function of the group with the lowest number was pollinators (Hymenoptera: Apidae). Although the diversity of insects and arachnids species found in coffee farms was high (H' = 5.10), the evenness and dominance index were relatively low. These results showed the potential of coffee plantations as ecosystems for conserving predatory arthropods biodiversity. Consequently, coffee cultivation practices and pest management strategies must prioritize the protection of beneficial insects such as natural enemies and pollinators.
