Abstract

Some flowering plants like common zinnia (Zinnia elegans (Jacq) Kuntze), marigold (Tagetes erecta Linnaeus), and cockscomb flowers (Celosia sp.) have been used as refugia and conservation plants for predators and parasitoids but are still not yet optimal. Planting refugia plants can affect insect diversity and evenness index, affecting the stability and balance of the agroecosystem. The study aimed to determine the effect of common zinnia, cockscomb flowers, and marigold as refugia on insects’ diversity and evenness index and their potential as a medium for conservation of predators and parasitoids. The study was conducted in organic rice fields in Batang Anai Sub-district, Padang Pariaman District, West Sumatra, from May to July 2020. The Insect was collected from plots covering an area of ??48 m2 and identified in the Bioecology laboratory, Faculty of Agriculture, Universitas Andalas. Planting common zinnia, marigolds, and cockscomb flowers increased the index of diversity and evenness of insects around rice fields. The index of diversity and evenness of insects on cockscomb flowers (H = 2.90) was higher than that of common zinnia (H = 2.61) and marigold (H = 2.63). Cockscomb flowers have more potential as a medium for conserving predators and parasitoids.

Abstract

Brown planthopper or BPH (Nilaparvata lugens Stal, Hemiptera: Delpachidae) is a significant pest that is a severe problem to rice plants in various places, including Bogor District, East Java Province. Resistance of several varieties of rice to BPH of Bogor Population has not been reported. One method to determine a variety's resistance is the honeydew test. This study aims to determine the resistance of several rice varieties to BPH of Bogor population. This study used six different varieties as treatments, and carried out in five replications. Those varieties were Pelita, Mapan, Situ Bagendit, Ciherang, Inpari-33, and IR-64. The observations were made on the area of honeydew spots produced by BPH after consuming sap of rice plant. This research showed that the Situ Bagendit variety was relatively resistant to BPH of Bogor population. The Mapan and Pelita varieties were quite susceptable, while Inpari-33, Ciherang, and IR-64 were moderate. The region of origin where BPH grows and the testing procedure can affect the resistance category of one variety.

Abstract

The density and attack rates of Spodoptera frugiperda have been reported in various maize cultivation in Indonesia, but there has never been a report in Sijunjung District, West Sumatra. The research was conducted to study the attack level, density, and distribution of S. frugiperda in Sijunjung District. The study was carried out in March -May 2023 using a survey method in 8 sub-districts in Sijunjung District. The results showed that S. frugiperda had spread and attacked maize crops evenly in Sijunjung District, but the attack rate (26.96%) and density (0.24 individuals) were low. The highest attack was found in Nagari Guguak (88.7%). The high or low rate of attacks is influenced by differences in varieties, planting ages, and maize cultivation techniques. Meanwhile, the density is more influenced by age differences.

Abstract

Spodoptera frugiperda J.E. Smith (Lepidoptera: Noctuidae), or the fall armyworm (FAW), is an invasive and highly polyphagous pest that threatens various food crops, including rice. This study aimed to assess the effects of several local rice cultivars from West Sumatra on the development and survival of S. frugiperda under laboratory conditions. The experiment was arranged in a completely randomized design with five treatments and ten replications. Four local rice cultivars (Cisokan, Batang Piaman, Kuriak Kusuik, and Bujang Marantau) were tested, with corn used as a reference host. Data were analyzed using analysis of variance (ANOVA). The observed parameters included the duration of each developmental stage, as well as the pre-oviposition, oviposition, and post-oviposition periods, fecundity, egg hatchability, larval survival to the pupal stage, pupal weight, adult emergence, and sex ratio. Host plant species significantly affected all developmental and reproductive parameters of S. frugiperda (p < 0.05). The total developmental duration was shorter on corn (37.20 ± 1.51 days) than on the local rice cultivars, which ranged from 41.54 to 41.90 days. The larval stage lasted longer on rice cultivars (mean 21.40 days) compared with corn (15.86 days). Female longevity and oviposition period were also greater on corn than on rice. Overall survival and the number of females emerging were lower on rice (73.20–78.80 individuals) than on corn (94.20 individuals). These results indicate that S. frugiperda is capable of completing its life cycle on local rice cultivars; however, development is slower, and reproductive potential is reduced compared to corn.

Abstract

Formulating a stable para-menthane-3,8-diol (PMD) nanoemulsion requires a balanced ratio of active ingredients and surfactants. Increasing the active ingredient may improve efficacy but can reduce stability, while excessive surfactant levels may cause unwanted foaming during application. This study evaluates the use of a defoamer to improve nanoparticle stability and enhance the biological activity of the formulations against Spodoptera frugiperda. The research was conducted in two stages: (1) characterization of particle stability using the DLS method and (2) evaluation of insecticidal activity through the leaf-dip bioassay. Data were analyzed using ANOVA followed by the LSD test; LC50 and LC95 values were determined via Probit analysis using POLO PLUS. The addition of a defoamer significantly improved the physicochemical properties and performance of the PMD nanoemulsion. The formulation achieved a refined particle size of 202.2 nm and a PDI of 0.20, both within acceptable nanoparticle standards. At a concentration of 0.25%, the defoamer-enhanced formulation demonstrated superior biological efficacy, including a 0.07% increase in LC95 efficiency and 3.14% growth inhibition. The treatment reduced pupal formation and adult emergence by 8% and altered the sex ratio. The addition of a defoamer improves the physical properties of the nanoemulsion and its biological efficacy against Spodoptera frugiperda.

Abstract

Fruit flies (Diptera: Tephritidae) are major pests of chili (Capsicum annuum Linnaeus) in tropical agroecosystems, but information on species dominance, infestation levels, and field susceptibility patterns of local chili varieties in West Sumatra remains limited. This study investigated Bactrocera spp. diversity, infestation levels, and varietal susceptibility patterns across four major chili-producing regencies in West Sumatra, Indonesia. Field surveys were conducted from July 2024 to March 2025 at 33 chili-growing sites in Agam, Solok, Tanah Datar, and Padang Pariaman. Fruit flies were monitored using methyl eugenol-baited modified Lynfield traps, while plant and fruit infestation were assessed through field observation and fruit dissection. Species diversity was evaluated using Shannon–Wiener, Simpson, and Pielou evenness indices. Differences in infestation among varieties were analyzed using the Kruskal–Wallis followed by Dunn’s multiple comparison test, while exploratory PCA and clustering were used to visualize infestation patterns. This study identified three fruit fly species associated with chili agroecosystems in West Sumatra, namely Bactrocera dorsalis, B. carambolae, and B. umbrosa. Among them, Bactrocera dorsalis overwhelmingly dominated the assemblages, resulting in low species diversity and evenness across regencies. Infestation levels differed among varieties, with Kuhay consistently showing the lowest plant, fruit, and overall infestation intensity. Aka, Keriting Bukittinggi, Rawit, and Kopay showed relatively higher infestation levels, although Kopay should be interpreted cautiously due to limited sample representation. These findings indicate differential field susceptibility among local chili varieties and suggest that low-infestation varieties such as Kuhay warrant further evaluation for integrated pest management and resistance-oriented breeding programs.
