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

Bemisia tabaci is a major pest in chili as it can act as a vector for transmitting the yellow curl virus. Endophytic bacteria have been reported to trigger plant defense against whiteflies. This study aimed to obtain a solid formula for the endophytic bacteria B. pseudomycoides strain SLBE1.1SN and a storage duration that effectively controls whitefly. This experimental study used a completely randomized design (CRD) consisting of 26 treatments and repeated three times. The treatments combined different types of endophytic bacterial carrier formulas and storage duration, synthetic insecticide treatment (Imidacloprid), and control. The treatments were applied to chili seeds and seedlings. The results showed that not all stored endophytic bacterial formulation could suppress the whitefly population on chili plants. The formula B. pseudomycoides strain SLBE1.1SN with rice straw as carrier material at six weeks storage was the best formula for controlling whitefly. This suggests that the formulation of stored endophytic bacteria not only reduced the number of eggs laid, but also suppressed the development of nymphs and imago.

Abstract

Fruit flies (Bactrocera spp.) are the most detrimental pests on siamese orange fruit (Citrus nobilis Linnaeus). One technique to control fruit flies that are safe for the environment and do not cause residues on plants is the use of attractants. The research aimed to study the effect of dose and application interval of basil essential oil for fruit fly control on Siamese orange plants. This research was conducted in citrus plantations of Gunung Omeh District, Lima Puluh Kota Regency, West Sumatra, Indonesia, and Insect Bioecology Laboratory, Faculty of Agriculture, Universitas Andalas. The study used a separate plot design consisting of doses of basil essential oil as the main plot and application intervals as subplots. The observed variables were species and the population of fruit flies. The results of observations found Three species of fruit flies, namely Bactrocera dorsalis, Bactrocera carambolae, and Bactrocera umbrosa, were successfully trapped during the observation with the highest number of catches of 278.33 individuals/trap, 15.33 individuals/trap, and 2.67 individuals/trap, respectively. Basil essential oil with a dose of 1.5 ml and an application interval of 3 days proved to be the most effective combination in trapping fruit flies compared to other doses and intervals. These results indicate that basil essential oil can be a potential alternative attractant in managing fruit fly populations on Siamese orange plants

Abstract

This study aims to identify the problems and develop rice agribusiness in Mentawai Islands from upstream to downstream and formulate appropriate policy recommendations to be implemented. The research location determined by purposive namely in the village Makalo and Malakopa District of South Pagai, Sikakap subdistrict Taikako Village, Village Saumanganya District of North Pagai, Bosua Village and Village Beriulou District of South Sipora, Village Rogdog and Madobag District of South Siberut. Respondents in this study were 30 farmers. Respondents farmers selected by simple random sampling method. The results showed that the majority of rice paddies new openings in six districts consist of peatlands with a depth varying from 0.4- > 2.0 meter, fields new openings that have been implemented in the Mentawai Islands in general can not be expected to result in maximum productivity due to problems of land suitability diverse. Farmers also do not take action appropriate technical culture starting from land preparation, seed selection, weeding, fertilizing and water management. Behaviorally agriculture, farmers in Mentawai Islands is not a society that blends with the culture of rice fields, it is because basically their agricultural base is dry land agriculture with farming patterns. This will certainly give a great challenge and not easy for the cultivation of rice in the Mentawai Islands.

Abstract

The gambir plant can serve as a raw material for botanical insecticides. Plant-based insecticides are made in nanoemulsion form to overcome the insecticide particle size problem. This study aims to obtain a gambir waste form that has the potential to be used as a botanical insecticide using nanotechnology. The laboratory experiments include preliminary and follow-up tests. The preliminary test involves testing each extract (liquid, solid, and raw gambir waste) at three concentrations using a completely randomized design with four replications. The follow-up test uses the residue method on leaves to test insecticidal activity. Creating nanoemulsion from gambir waste involves mixing organic and liquid phases through spontaneous emulsification. The insecticidal effectiveness of this nanoemulsion is tested on Croccidolomia pavonana. The results show that solid and liquid gambir waste has the potential to be used as alternative insecticides, which can influence the mortality of C. pavonana with an LC50 concentration of 0.22 (solid waste) and 0. 29 (liquid waste), while LC95 is 2.44 (solid waste) and 2.52 (liquid waste). The research promotes utilizing natural resources and innovative technologies, advancing environmentally conscious pest control methods, and fostering sustainable agricultural systems.

Abstract

The objective of this study was to get entomopathogenic fungi isolates of bean plant rhizosphere derived from Nagari Sawah Tangah, District Pariangan, Tanah Datar Regency and to determine their pathogenicity on pod borer E. zinckenella. Isolation method was performed by diluting the soil samples in a serial dilution into 10-3 and cultured in PDA media. Furthermore, the purification was based on the shape and color of the fungus colonies. A total of 16 isolates obtained at the initial stage were selected by testing them against the fifth instar larvae Tenebrio molitor. Results showed that only 4 isolates (STA 1, STA 2.2, STA 5, and STB 3.1) could be further tested against E. zinckenella pod borer using completely randomized design (CRD). The highest pathogenicity isolates was exhibited by STA 1 belonged to Metarhizium genera.

Abstract

Forecasting of brown planthopper attack or BPH (Nilaparvata lugens Stal) using artificial intelligence and vegetation index of Sentinel-2 Satellite Imagery improves forecasting the incidence of hopperburn. This study aimed to determine the accuracy and correlation of the random forest classification of Sentinel-2 imagery to the incidence of hopperburn reported by Plant Pest Organisms Observer (PPOO) and determine the best method for predicting it. The study was done through observation and secondary data processing about the age of the plant, the incidence of hopperburn by BPH, interviews with farmers, and PPOO. The results showed that the hopperburn NDVI index ranged from 0.23 - 3.8. The random forest classification accuracy was high (Kappa Index = 0.82). The relationship between the hopperburn area from the PPOO report and the predicted area from Sentinel-2 images classified as (R2 = 0.53, R = 0.728) with the equation Y = -1.5 + 0.82 X. The correlation can be improved using spatial regression Geographically Weighted Regression (GWR4) with the best gaussian distance of 1.76 km (R2 = 0.6, R = 0.77). The best prediction for the NDVI stage of hopperburn attack time series with random forest (RMSE = 0.12819) was better than the prediction of the hopperburn attack time series with the exponential smoothing method from the PPOO report (RMSE 3.302184).
