Rice black bugs what are the benefit for researcher and farmer?4 answersResearchers benefit from identifying entomopathogenic fungi like Paecilomyces sp. and Fusarium sp. that attack rice black bugs, aiding in pest management. Understanding the systematic relationships of Philippine rice black bugs helps researchers classify species effectively. Sampling techniques like fluorescent-street-light traps and Petromax gas-lantern traps assist in studying the population dynamics of Malayan black bugs in rice fields, aiding researchers in data collection and analysis. Farmers benefit from research findings that suggest alternative pest management strategies like the ecological rice-animal co-culture system, which can increase rice yields, reduce nitrogen losses, and lower input costs, ultimately enhancing their net income and promoting sustainable intensification. By bridging knowledge gaps and providing practical solutions, research contributes to more effective pest control and improved agricultural practices for farmers.
What insects affect stored rice?5 answersStored rice is susceptible to infestation by various insect pests, impacting both quantity and quality. Common pests include Sitophilus oryzae, Rhyzopertha dominica, Lasioderma serricorne, Oryzaephilus surinamensis, Tribolium castaneum, and Cryptolestes ferrugineus. Among these, S. oryzae is a key pest, with parasitoids like Anisopteromalus calandrae and Lariophagus distinguendus showing potential for biological control. The infestation levels can vary based on storage conditions, with factors like storage materials influencing pest populations and damage levels. Additionally, fortifying rice with substances like spearmint or basil can help reduce infestation and population growth of these insect species, showcasing promise for stored product insect control. Understanding the diversity and abundance of these pests is crucial for effective Integrated Pest Management strategies in rice storage facilities.
Which authors have made significant contributions to the field of inventory management in rice retailing?4 answersArchana Sasi and Thiruselvan Subramanian have made significant contributions to inventory management in rice retailing by developing forecasting models using time series techniques like ARIMA and Double Exponential Smoothing. Additionally, Artika Lestari Taraja's research highlights the importance of inventory management methods like Economic Order Quantity (EOQ) in optimizing inventory levels and reducing costs in trading businesses. These studies collectively emphasize the crucial role of accurate demand forecasting and efficient inventory control in the rice retailing sector, showcasing how various methods and models can enhance operational efficiency and cost-effectiveness in managing rice inventory.
Data to be gathered when collecting arthropod in rice fields?2 answersWhen collecting arthropods in rice fields, the following data can be gathered: abundance, diversity, composition, and seasonality patterns of arthropods. The abundance of arthropods can be measured by counting the number of individuals collected using traps such as water pan traps, pitfall traps, and yellow pan traps. The diversity of arthropods can be assessed by identifying the species present and calculating diversity indices such as Shannon index and Pilou index. The composition of arthropods can be determined by categorizing them into different taxonomic groups and ecological functional groups. Additionally, the seasonality patterns of arthropods can be analyzed by collecting samples at different time points throughout the rice growing season.
How to characterize rice bug?2 answersRice bugs can be characterized using different methods. One approach is to use computer vision-based systems that utilize local descriptors such as local binary pattern, histogram of oriented gradients, and GIST to analyze rice seed images. Another method involves using a compound represented by formula (I) as a bug repellent. Additionally, the identity, distribution, hosts/species affected, and natural enemies of rice bugs can be studied to further characterize them. It is also possible to detect and classify rice plant diseases, including those caused by bugs, using image-based machine learning approaches. This involves capturing images of diseased symptoms in rice plants and using deep convolutional neural networks as feature extractors and support vector machines as classifiers.
What is the status of rice in asia?5 answersRice is a staple food in Asia, with over 90% of global rice production and consumption occurring in the region. It is cultivated on millions of hectares of land, particularly in South Asian countries. The rice-wheat cropping system is widely followed, except in Sri Lanka where the rice-rice cropping system is predominant. Rice production has seen rapid growth in recent years, mainly due to increased investment in agriculture and expansion of rice production in rice-importing countries. The genetic diversity of rice is significant, with different varieties arising from natural and human selection. Rice farming has played a crucial role in the development of civilizations and ancient states in East and Southeast Asia. The spread of rice farming has been linked to the establishment of sedentism and the spread of major language families in the region.
