Abstract

Integrated Pest Management (IPM) is a pest control method that combines several control techniques by considering ecological, economic, and sociological consequences. Management efforts with IPM principles can be conducted by cultivating healthy plants and entomopathogen application. This study examined the IPM package's success for controlling fall armyworm (Spodoptera frugiperda) in maize field. This research was conducted in a farmer's maize plantation in the West Pasaman District from August to December 2021. The study used a Randomized Block Design (RBD) which consisted of three treatments and five replications. The treatments were different cultivation techniques using IPM, Non-IPM, and control. The variables observed were the population of S. frugiperda (individual/plant), attack rate (%), attack intensity (%), cob weight (g/cob), and farming cost (IDR). The results showed that the IPM and Non-IPM maize cultivation techniques had no different effect on S. frugiperda, especially survival stage, attack rate, intensity, and yield. However, this effect was higher than the control. In addition, the economic benefits of cultivation with IPM were higher than non-IPM. Therefore, this IPM package can be recommended for controlling S. frugiperda because it is also economically profitable and environmentally friendly.

Abstract

Coconut-based production generates waste such as coconut husk, which contains up to 35% lignocellulose—a valuable raw material for furfural production. This study aimed to determine the impact of coconut maturity level and coconut husk section on the lignocellulose content in coconut husk. This study used a randomized group design with two factors: coconut maturity level and coconut husk section. The variables observed were moisture, extractive, cellulose, hemicellulose, and lignin contents. Analysis of Variance (ANOVA) was performed for data analysis, followed by Duncan's Multiple Range Test (DMRT). The coconut fruits used were immature and mature ones. This study analyzed the husk at the proximal end, equator, and distal end of the coconut fruit. The results show significant effects of coconut maturity level on the chemical composition of coconut husk at the three sections of the coconut, indicating coconut husk’s potential as a raw material for furfural production.

Abstract

The conservation of natural enemies through the use of refugia plants is an important strategy to enhance arthropod diversity and stability in rice ecosystems, but its effectiveness may vary across locations. This study aimed to evaluate the potential of several refugia plant species in increasing arthropod diversity in rice fields of South Solok Regency, Indonesia. The study was conducted from December 2024 to April 2025 in Nagari Lubuk Gadang, South Solok Regency. Arthropod sampling was performed using a D-VAC (vacuum sampler) and insect net. The experiment was arranged in a randomized block design with six treatments (Cosmos caudatus, Ageratum conyzoides, Portulaca oleracea, Celosia cristata, Tagetes erecta, control), in four replications respectively. Observations included species composition, abundance, and diversity indices. The results showed that refugia plants contributed to the suppression of pest populations and improved the stability of arthropod communities. A total of 9 orders, 32 families, and 44 species were recorded, comprising 1,167 individuals, with herbivores accounting for 71.55% of the total population. The dominant herbivores were Cicadulina bipunctata, Leptocorisa oratorius, and Nilaparvata lugens, which were generally more abundant in rice fields without refugia. Predator and parasitoid abundance tended to be higher in the rice fields surrounded by C. cristata and T. erecta. The highest arthropod diversity was recorded in plots with T. erecta (H’ = 3.02), low dominance (0.07) and high evenness (0.86). Therefore, C. cristata and T. erecta are recommended as refugia plants to support sustainable integrated pest management in rice fields of mid-altitude areas.

Abstract

Yanti Y, Warnita, Reflin, Busniah M. 2018. Indigenous endophyte bacteria ability to control Ralstonia and Fusarium wilt disease on chili pepper. Biodiversitas 19: 1532-1538. Bacterial wilt and Fusarium wilt caused by Ralstonia syzigii subsp. indonesiensis and Fusarium oxysporum f.sp. capsici (Foc), respectively are the most damaging vascular pathogens in chili pepper (Capsicum annuum L.) and many other crops limiting their production, worldwide. Various strategies have been developed to control wilt pathogens including the application of chemical pesticides, which generally considered as the most effective and fastest strategy for plant disease management. However, effective chemicals for wilt pathogens of chili pepper plants are not available, yet. Endophytic bacteria considered as one of options to control vascular wilt disease because of its ability to live and colonize in internal roots of plants. Previous research has been done to select endophytic indigenous bacteria isolates which can promote growth rate of chili pepper. The purpose of the research was to identify the selected indigenous endophyte bacteria isolates acquired from our previous study using 16S rRNA identifications and to screen the selected endophytic indigenous bacteria to control both R. syzigii subsp. indonesiensis and Foc. Results from 16S r RNA analysis showed that all of 9 isolates were identified as Bacillus spp., such as Bacillus cereus ATCC 14579, Bacillus pseudomycoides strain NBRC 101232, Bacillus toyonensis strain BCT-7112, Bacillus thuringiensis strain ATCC 10792, Bacillus weihenstephanensis strain DSM 11821, Bacillus mycoides strain 273, Bacillus cereus strain NBRC 15305, Bacillus bingmayongensis strain FJAT-13831 and Bacillus manliponensis strain BL4-6. Our results showed that most of endophytic bacteria isolates application could control both bacterial and Fusarium wilt diseases. Six out of nine isolates can suppress R. syzigii subsp. indonesiensis without developing any symptoms and five isolates could suppress symptoms of Foc. Isolates Bacillus pseudomycoides strain NBRC 101232 Bacillus thuringiensis strain ATCC 10792 and Bacillus mycoides strain 273 were potential for control Foc and R. syzigii subsp. indonesiensis in chili pepper.

Abstract. Rahma H, Nurbailis, Busniah M, Kristina N, Larasati Y. 2021. The potential of endophytic bacteria to suppress bacterial leaf blight in rice plants. Biodiversitas 23: 775-782. Endophytic bacteria are potential as biocontrol agents against bacterial leaf blight (BLB) disease caused by Xanthomonas oryzae pv. oryzae in rice to support sustainable agriculture. This study aimed to select and characterize 22 endophytic bacteria isolated from healthy rice, determine their ability to promote plant growth and suppress bacterial leaf blight disease in rice and also identify potential endophytic bacterial isolates. The study was arranged in a Completely Randomized Design with 24 treatments and three repetitions. The treatments used in the current study consisted of Xanthomonas oryzae infected plants and treated with endophytic bacterial isolates; infected plants without endophytic bacteria treatment (positive control), non-infected plants (negative control). Identification of potential endophytic bacteria was performed based on 16S rRNA sequences. Three out of 22 bacterial isolates, i.e., LmB1, LmA6, and LmB2 were able to suppress bacterial leaf blight disease with severity levels of 35.82%, 23.78%, and 23.78%, respectively. Based on the rice plant growth parameters, three bacterial isolates (LmA6, LmB1, and LmB35) were able to increase the growth of rice plants with an average value of 69.56%, 56.51%, and 47.82%, respectively. Two bacterial isolates, i.e., LmB 1 and LmA6 suppress the development of bacterial leaf blight disease and increase the growth of rice plants. Based on DNA sequence comparisons of DNA fragments amplified by 16S rRNA related marker of the selected bacterial isolates and database, then LmA6, LmB2, LmB1, and LmB35 had similarities with Bacillus cereus MD152 (96.87%), Bacillus thuringiensis ATCC 10792 (98.20%), Ochrobactrum intermedium strain OI1 (97.52%), and Stenotrophomonas maltophilia strain A1w2 (97.92%), respectively. Our study revealed that the indigenous endophytic bacteria from rice plants could be potential biological agents for controlling bacterial leaf blight disease and increasing plant growth.

Abstract. Busniah M, Efendi S, Trizelia, Hermanda S. 2025. Helopeltis theivora dynamics and damage on cocoa clones under agronomic management in West Sumatra, Indonesia. Biodiversitas 26: 5118-5124. This study analyzed the comparative resistance of cocoa clones to Helopeltis theivora in two types of cocoa plantations in West Sumatra, Indonesia. The comparison was made between plantations intensively managed by CV Scorpio and small plantations, focusing on two main clones, ICS 60 and TSH 858. The results showed that cocoa cultivation practices in intensive and smallholder cocoa plantations affected the abundance, percentage, and intensity of damage caused by H. theivora. The population and damage levels of H. theivora were higher in smallholder cocoa plantations than in intensive plantations. The type of clone cultivated also affects the abundance and damage level of H. theivora on cocoa plants. ICS 60 clone showed resistance to H. theivora compared to TSH 858 clone. Only the resistance of these clones to H. theivora was affected by cocoa cultivation practices. The resistance of these clones decreased in cocoa plantations that were not intensively managed. Secondary branches were the location of the highest damage intensity, and H. theivora showed a preference for attacking pods measuring 7-15 cm on ICS 60 and >15 cm on TSH 858. This study clearly shows that intensive cultivation practices play an important role in controlling the population of the pest H. theivora. The choice of cocoa clones is also a determining factor. The ICS 60 clone is more resistant to H. theivora. However, genetic resistance in cocoa clones is not absolute. Synergy between the selection of appropriate clones and good cultivation practices is the key to successful control of H. theivora.
