As an invasive pest, the population of S. frugiperda continues to increase exponentially, leading to outbreaks. Both internal factors (biology) and external factors (weather, host, and natural enemies) can affect the growth rate of pest populations. This research was conducted to assess the population dynamics of S. frugiperda based on the extent of its infestation and damage to maize post-invasion in Lampung Province. Observations were made in maize fields in 15 districts of Lampung Province from 2019 to 2022. Damage intensity was calculated based on the leaf damage scale. Weather data from 2019 to 2022 was obtained from the Lampung Province Central Statistics Agency. The research results indicate that upon the initial introduction of S. frugiperda to Lampung Province, the population increased exponentially, as observed based on the level of infestation and damage to maize. There was an outbreak from late 2019 to early 2020, and after that, there was a population decline. The population increase coincided with the early rainy season, which is associated with the beginning of the maize planting season. Although the level of damage to the maize is considered slight, S. frugiperda can cause anywhere between 21.94% to 51.38% of damage.","PeriodicalId":31803,"journal":{"name":"Jurnal Hama dan Penyakit Tumbuhan Tropika","volume":"2021 14","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140246131","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Symptoms of Geminivirus infection are quite easy to find in chili plants because the symptoms are quite typical: mosaic, yellowing, small leaves, leaf lamina malformation, and stunting. The visual changes in leaf morphology are due to the leaf tissue structure, such as the upper and lower epidermis and the mesophyll tissue, including the palisade and sponge. There is little information about changes in the structure of chili plants infected with the Geminivirus. Therefore, this study aims to add information about changes in the leaf tissue structure of chili plants infected with the Geminivirus. The structural changes observed were palisades. Long palisades were less preferred by whiteflies, so the incidence of geminivirus disease was lower. This information is a reference for assembling chili plants with better structural resistance. The method used was a cross-section of chili leaves, double staining, and observation with a light microscope. Observations on mild symptoms showed epidermal cells shrinking. Some parts of palisade leaves were composed of two layers with shortened cells and tend to be oval. The symptom is that the upper epidermal cells were shrunken, and the palisade also tends to shorten. Severe symptoms of the epidermis on the leaves were curly, shriveled, thinned, and even dying; the palisade is shortened and sometimes looks irregular/tight. Changes in the leaf tissue of chili plants infected with the Geminivirus cause changes at the ultra-structural, cell, or tissue level, depending on the type of virus attack and the attack level.","PeriodicalId":31803,"journal":{"name":"Jurnal Hama dan Penyakit Tumbuhan Tropika","volume":"46 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140245919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to observe the dynamic population during shallot off and on-seasons. Additionally, this study aims to determine the correlation between S. exigua moth captures and damage intensity. The research was conducted from November to May in Kretek Village, Parangtritis District, Bantul Regency, Special Region of Yogyakarta Province, Indonesia. Population dynamic observations of S. exigua during the off-season and on-season were conducted in a 100 x 100 m plot with ten pheromone traps installed. The early monitoring study consisted of two treatments: installed pheromone and control (without the installation of pheromones). The plots were separated by approximately 500 m and were approximately 3500 m2 in size. The results showed that S. exigua exists and can survive during shallot off-season and on-season planting periods. The number of male S. exigua moths captured during the on-season was higher compared to the off-season. The fluctuation of rainfall and the number of S. exigua during the off and on-seasons were also observed, showing that rainfall significantly affected the number of S. exigua moths captured. However, the relationship between rainfall and S. exigua population needs further study. Strong positive correlations between population and damage intensity in pheromone-treated fields between three to seven days after observation (DAO) demonstrated that pheromone traps can be used as a monitoring tool for S. exigua. The close correlation between the S. exigua captured and the intensity of the damage that will occur can be prevented by controlling them by farmers.","PeriodicalId":31803,"journal":{"name":"Jurnal Hama dan Penyakit Tumbuhan Tropika","volume":"27 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140265923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The in vitro experiment aimed to determine the effect of the extract on inhibiting C. capsici growth in potato sucrose agar (PSA) medium incorporating the turmeric rhizome extract. The variables examined were mycelial growth, fungal sporulation, and spore germination. The in vivo experiment aimed to evaluate the effectiveness of the extract in reducing disease development on red chili peppers. The treatments were conducted using a completely randomized design with five concentration treatments and three replicates. The variables examined were radial mycelial growth zone diameter, fungal sporulation, spore germination, and disease intensity. Data were analyzed by analysis of variance, and the least significant difference was used for comparing means between treatments. The results of these experiments showed that ethanolic turmeric rhizome extract exhibited antifungal activity against C. capsici both in vitro and in vivo conditions. Turmeric rhizome extracts with concentrations of 1%, 2%, 3%, and 4% significantly inhibited mycelial growth, and even at a 4% concentration, C. capsici fungal colonies did not grow. Evaluation of the effect of the extract on fungal sporulation showed that inhibition occurred at a concentration of 3%, while inhibition of spore germination occurred at concentrations of 1%, 2%, and 3%. Application of turmeric extract at concentrations of 1%, 2%, 3%, and 4% effectively reduced the intensity of anthracnose on red chili.","PeriodicalId":31803,"journal":{"name":"Jurnal Hama dan Penyakit Tumbuhan Tropika","volume":"66 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140408358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Controlling this nematode is challenging due to its wide host range. The use of synthetic nematicides harms the environment; therefore, alternative controls, such as biological methods, are necessary. Among the biological agents, one group includes endophytic bacteria that reside in plant tissues and do not cause harm to plants. These bacteria enhance plant resistance to pests and pathogens while promoting plant growth. The study aimed to acquire endophytes, Bacillus spp. strains capable of controlling Meloidogyne sp. while stimulating the growth of tomato plants. The research employed a completely randomized design (CRD) comprising seven treatments and five replications. The treatments consisted of B. cereus strain SNE 2.2, TLE 2.3 and TLE 1.1, B. pseudomycoides strain EPL 1.1.3, B. toyonensis strain EPL 1.1.4, positive control (without the introduction of Bacillus spp. and inoculation with Meloidogyne sp.) and negative control (without Bacillus spp. and without Meloidogyne sp.). Bacillus spp. endophyites were introduced in two stages: into the seeds and into the roots of tomato seedlings for 15 min. The observed variables were the development of Meloidogyne sp., endophytic colonization of Bacillus spp., and plant growth. The results demonstrated that all Bacillus spp. were effective in controlling Meloidogyne sp. and enhancing the growth of tomato plants.
