Strawberry pear (pitahaya, pitaya) [Hylocereus undatus (Haw.) Britt. and Rose] postharvest fruit rot was found at an agricultural products store in Itoman city, Okinawa Prefecture
in 2006. The symptoms included depressed, water-soaked lesions with olive to black powdery spots coalescing into a soft rot.
The causal fungus was identified as Bipolaris cactivora (Petrak) Alcorn. This is the first report of strawberry pear fruit rot caused by B. cactivora. 相似文献

Objective
To evaluate the use of an experimental colloid model for teaching veterinary anesthesia residents ultrasound-guided technique for nerve blockade.Study design
Prospective, blinded and randomized.Methods
Colloid models were constructed for practice in ultrasound-guided needle location. Nine veterinary anesthesia residents with no prior experience of ultrasound-guided technique for nerve blocks were randomly divided into three groups. Each group received theoretical orientation. Two groups were assigned to practical training using the experimental model: group 1 (G1) received 2 hours of training and group 2 (G2) received 1 hour of training prior to testing with specific tasks. Group 3 (G3) received no practical training. During testing, the time required for task completion (e.g., display of structures and positioning a needle) and the number of failures were recorded.Results
The average times to completion of the tasks and the number of technical failures were: G1, 47 seconds and 1 failure; G2, 68 seconds and 2 failures; G3, 187 seconds and 7 failures.Conclusions and clinical relevance
In residents with no prior experience of ultrasound-guided needle placement, using an experimental colloid model and a longer training period was associated with increased accuracy and decreased time to task completion. Based on the results of this study, training with an experimental model can be recommended to improve the speed and accuracy of needle manipulation using ultrasound in clinicians with no prior experience of ultrasound-guided technique. 相似文献3.

An outbreak of black mottle and dieback on basil (Ocimum basilicum L.; Lamiaceae) was recorded in a greenhouse in Okinawa Prefecture, Japan during 2004. The causal agent was identified as
Alternaria alternata (Fr.) Keissler based on morphological characters and growth temperature. This report is the first of Alternaria leaf spot
of basil caused by A. alternata. 相似文献

The early stage of weathering / soil formation processes from new volcanic mudflow (new lahar materials) brought from Mt. Pinatubo was examined. For this purpose, comparative studies on the physical / chemical characteristics of the new lahar materials and soils formed by the deposition of old lahar materials were conducted. Original soils contained less coarse sand, more silt, and clay than the new lahar materials. Increase in the clay content of the original soils reflected the progression of weathering. The occurrence of a higher leaching process of Fe, Ca, and Mg and of a moderate accumulation of organic matter in the original soils was suggested, based on the differences in the soil elemental composition and chemical properties. Values of base saturation and phosphate absorption coefficient (PAC) of the new lahar materials were 388% and 44, while those of all the original soils ranged 15–160% and 55–894, respectively. With the progression of weathering, the PAC value tended to increase gradually while the base saturation value decreased abruptly under the environmental conditions prevailing in the Philippines. 相似文献

Gilbertella persicaria stem rot is a disease that causes rotting in the stem nodules and fruits of pitaya. Here, we aimed to study the ecology of G. persicaria and its biological control using several Bacillus subtilis strains isolated from the phyllosphere. Sporangiospores of G. persicaria were detected on different parts of the plant, with maximum density (c.239.9 propagules/cm2) found on the petals after flowering, and spore germination was observed to be considerably affected by humidity. Furthermore, the study revealed that an incision wound of at least 2 mm depth was necessary for infection by the pathogen to the stem nodule, and exposure to high temperatures (50°C) accelerated disease incidence, by disrupting resistance to the spread of the pathogen. Additionally, biological control of G. persicaria was effectively achieved by inoculation with B. subtilis strains isolated from pitaya stem nodules. Intriguingly, treatment with antagonistic bacteria reduced stem rot incidence to zero (bacterial suspension: PNB-5, PNB-7, and PNB-93; culture filtrate: PNB-7, PNB-93, and PNB-95), equivalent to that achieved by fungicide application in both prophylactic and simultaneous treatments. Collectively, this is the first study to demonstrate the ecology of G. persicaria and to show the potential applicability of phyllosphere bacterial strains for biological control of G. persicaria in pitaya, which could help develop effective integrated disease management strategies for the control of pitaya stem rot. 相似文献

- Bivalves are important components of freshwater ecosystems; however, they are also one of the most threatened animal groups, especially members of the order Unionida. The main threats to freshwater bivalves are habitat modification and invasive species. Protected areas are a common way to minimize impacts and preserve native species, but they are rarely designated with a focus on freshwater invertebrates.
- The main goal of this article was to describe the distribution of freshwater bivalves in the state of Rio de Janeiro, and the relationship between these species and bioclimatic areas, land use and protected areas.
- Five native and two invasive bivalve species have been reported in Rio de Janeiro. They occur mainly in bioclimatic areas related to the Paraíba do Sul River and Campista Lowlands. The few records of bivalves inside protected areas are in areas of sustainable use that offer a lower level of protection, and frequently in sympatry with invasive bivalves.
- Thus, the established protected areas in Rio de Janeiro are not adequately effective for freshwater bivalve conservation, and some species remain under threat even within them. Freshwater bivalves thus remain largely unprotected in the state.
- The development of new protected areas and management plans should consider other faunal groups that are usually ignored, such as freshwater bivalves, to achieve more inclusive and effective protection.
