Abstract

Cocoa (Theobroma cacao) is one of the important commodities in Indonesia. The quality of cocoa beans has decreased during storage, one of which is due to the attack of Araecerus fasciculatus (De Geer). This pest attack can be overcome by fumigation that is safe for the environment through the use of essential oil. The study aimed to examine the mortality and repellent effects of kaffir lime leaves essential oil (KLLEO) to A. fasciculatus and to analyze the compound content of active fraction KLLEO using GC-MS. Research stages included maintenance and insect rearing, toxicity and repellency tests, fractionation, and analysis of active fraction compounds of essential oils. The study was designed using CRD with 6 treatments and 4 replications. The n-hexane fraction of KLLEO caused the highest mortality of A. fasciculatus adults after 72 hours of fumigation. The LD50 and LD95 values of the n-hexane fraction of KLLEO were 0.30 and 1.66 ml/l air, respectively. The dose at 1 ml/l air caused the highest mortality of A. fasciculatus adult by 73.75%. Examine using an olfactometer, KLLEO has high repellency against adult A. fasciculatus with the value of the repellency index reaching 100% at 1 ml/l air. The most dominant compound in the n-hexane fraction of KLLEO was the citronellal. Therefore, the KLLEO has some potential to be expanded as a botanical fumigant towards A. fasciculatus.

Abstract

Mass rearing techniques for the production of Spodoptera frugiperda larvae in large quantities as research materials is important to be developed. Baby corn has the potential to be observed as alternative feed for mass rearing of fall armyworms. However, the biology and life table of S. frugiperda feeding on baby corn has not been studied. This research aims to study the morphology, biology, and life table of S. frugiperda fed on baby corn. Larvae of F1 fall armyworm were reared singly and fed with baby corn, after pupation it was moved to containers. Thirty pairs of adults were reared in a cage filled maize plant. Observations conducted daily from the eggs until the adult died. Results showed variations in the color and size of the eggs, larvae, pupae, and adults. Developmental periods of eggs, larvae, and pre-pupae were 2.47, 14.96, and 1.83l days. Pupal period was 9.75 days (male) and 8.81 days (female). The life cycle were 37.69 days (male), and 37.7 days (female). Duration of pre-oviposition, oviposition, post-oviposition were 1.60, 7.90, and 2.26 days. Adult longevity was 11.34 days (male) and 11.76 days (female). The average number of eggs laid was 1.365,86/female with a hatch rate of 94,68%. Survival curve of S. frugiperda was type I, with GRR  of 1.442,49 individuals/generations, and  the Ro was 1.342,77 individuals/females/generation. Ther was 0.23 individual/female/day, the T  was 31.23 days, and the DT was 3.01 days. This result showed that baby corn can be an alternative feed for mass rearing of S. frugiperda.

Abstract

Release of new varieties requires qualitative as well as quantitative characters of the lines. For rice varieties, resistance to brown plant hopper (BPH) (Nilaparvata lugens, Stí¥l) (Hemiptera: Delphacidae) is an important character that should be tested. The purpose of this study was to determine the resistance of new rice lines of rice cultivar to BPH. In this study, the tests were carried out on 6 (six) lines of candidate varieties developed by IPB University, namely TCIPB202101, TCIPB202102, TCIPB202103, TCIPB202104, TCIPB202105, and TCIPB202106. Resistance to BPH assays was conducted by screening and population development tests. Inpari 30 and Ciherang varieties were used as controls. The results showed that the TCIPB202106 line is the most resistant to BPH attack, while the TCIPB202103 line is the most susceptible to BPH attack. The average number of nymphs in the TCIPB202106 line was three times lower than those in Inpari 30 and Ciherang. The results of the population growth test were in line with the results of the screening test which indicated that the TCIPB202106 line is classified as moderately resistant to BPH.

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

Intense insecticide application is thought to cause a decline in bee colonies worldwide. Bees are effective pollinators in increasing the production of agricultural commodities. The stingless bee Tetragonula laeviceps (Apidae: Meliponini) is widely cultivated and found around plantations. The insecticides used in the toxicity test were imidacloprid 200 g/L, fipronil 50 g/L, lambda-cyhalothrin 25 g/L, profenofos 500 g/L, and chlorantraniliprole 50 g/L followed by a semi-field test using imidacloprid, fipronil, and profenofos insecticides on the cucumber plant. The LC50 value showed that exposure to imidacloprid, fipronil, and profenofos insecticides caused toxic effects on T. laeviceps by contact and orally. Lambda-cyhalothrin was found harmful on contact exposure, in contrast, chlorantraniliprole was harmful through oral. Classification of insecticide toxicity based on LD50 contact for imidacloprid, fipronil, lambda-cyhalothrin, and profenofos were very toxic and needed a risk assessment. However, chlorantraniliprole was classified as moderately toxic and low risk. In semi-field test results, imidacloprid and fipronil insecticides caused a significant decrease in the leave-return and bee-visiting activity on cucumber flowers. These insecticides also produced a low average yield of fruit weight. Insecticide application can affect the role of T. laeviceps as the pollinator which impacts the production of agricultural commodities.

Abstract

Rice (Oryza sativa) is an important staple crop for more than half of the world's population to fulfill required nutrients. The most important pest in rice crops is the field rat (Rattus argentiventer), which causes damage and significant yield losses during almost every growing season. One method of rat control is the Trap Barrier System (TBS) which consists of fences, mass/multiple live traps, and trap crops and was able to continuously catch rats during the growing season. The objectives of this study were to count rat captured in TBS during one planting season in fallow lands, identify attack source, and calculate rat damage intensity. The study was conducted on one hectare of rice field and number of rat caught were observed daily. Results showed that 4,580 rats were caught, consisting of 57% males and 43% females, with 94% adults and 6% juveniles. Average rat damage intensity was 15% and the highest number of rats caught were in trap 8, 9, and 10 which were located on the north side and had many suitable shelters for rats.

Abstract

Fall armyworm (FAW), Spodoptera frugiperda (Smith) is an important pest on maize. Common control carried out by farmers in controlling the pest is by using synthetic insecticides. However, the improper use of synthetic insecticides can cause negative impacts. One strategy to control pests that is safe and environmentally friendly is by using botanical insecticides. Soursop (Annona muricata) leaves, yam bean (Pachyrizus erosus) seeds, and Javanese long pepper (Piper retrofractum) extracts are known to be able to control various insect pests. The aim of this research was to study the effectiveness of soursop leaves, yam bean seeds, and Javanese long pepper extracts on mortality of second instar larvae of FAW. Two test methods used to assess the three extracts on the mortality of S. frugiperda larvae were the leaf residual and the topical application methods. Insect mortality levels were processed using probit analysis to obtain lethal concentration (LC) and lethal dose (LD) values for each extract. The results showed that P. retrofractum extracts showed highest mortality effect on S. frugiperda than P. erosus and A. muricata extracts both on leaf residual and topical application methods. The LC50 and LC95 values of P. retrofractum extract were 0.142% and 0.595%, respectively. Meanwhile the LD50 and LD95 of P. retrofractum extract 0.10 µg/larvae and 0.40 µg/larva, respectively.

Abstract

One of the main problems in the cultivation of Brassicaceae vegetable plants is the attack of diamondback moth Plutella xylostella (Linnaeus). Extracts of Piper aduncum and Aglaia odorata have the potential to be used as botanical insecticides because they contain compounds that are toxic to insects. This study aims to evaluate the toxicity and feeding inhibition activity of hexane-extract of P. aduncum fruits and methanol-extract of A. odorata twigs against second instar larvae of diamondback moth. Extraction was carried out using the maceration method with a powder-to-solvent ratio of 1:10 (w/v). The diamondback moth insects used were from colonies reared in the laboratory. The lethal effect test was conducted using the leaf-dip method with test concentrations equivalent to LC15, LC35, LC55, LC75, LC95, and a control. The feeding inhibition test was conducted using the choice-test method with test concentrations equivalent to LC15, LC35, LC55, and a control. The results show that the hexane-extract of P. aduncum fruit is more toxic to second instar P. xylostella larvae than the methanol-extract of A. odorata twigs based on the probit analysis value of the relationship between concentration and mortality. The LC50 and LC95 values of P. aduncum extract were 0.07% and 0.14%, respectively, while the LC50 and LC95 values of A. odorata extract were 1.63% and 4.72%. Additionally, P. aduncum and A. odorata extracts also exhibited feeding against diamondback moth at concentrations of 0.07% and 1.77%, respectively. The combined effects of direct toxicity and feeding inhibition contributed to the mortality of the test insects. Thus, these two extracts, escpecially P. aduncum extract wich demonstrated higher effectiveness, have a great potential as botanical insecticides for controlling diamondback moth in Indonesia.

Abstract

The mealybug Maconellicoccus multipori (Takahashi) was identified on black pepper (Piper nigrum L.) seedlings in a greenhouse in Bogor, West Java, using both molecular and morphological characterization. Two mealybug isolates were successfully amplified with primer pairs targeting the LCO region of the mitochondrial cytochrome oxidase I (COI) gene, yielding a 491 bp PCR product. The nucleotide sequences of both isolates (GenBank accession numbers LC666906 and LC666907) were identical. Phylogenetic analysis revealed that the Bogor isolates clustered closely with M. multipori populations from China and Thailand, with high sequence homology of 99.30% and 99.10%, respectively. Morphological observations of the adult female specimens further confirmed their identity as M. multipori, based on key diagnostic features including body size, antennal segmentation, cerarii pattern, and distribution of pores and ducts, which correspond to descriptions in established taxonomic keys. This study provides the first molecular characterization of M. multipori in Indonesia. The COI sequence data obtained enhances reference databases for DNA barcoding and strengthens early detection strategies for pest monitoring. These findings are crucial for supporting quarantine inspections, management, and control of M. multipori in black pepper nurseries and preventing its spread to other crops.
