Rice varieties that are resistant to rice black bug (Scotinophara coaractata)?
Best insight from top research papers
Ten dominant rice varieties from southern China were evaluated for resistance to Southern rice black-streaked dwarf virus (SRBSDV) transmitted by the white-backed planthopper. While no immune resistance was observed, differences in infection rates, symptom severity, virus titers, and insect vector virus acquisition potency were noted among the varieties . On the other hand, a study identified a BC2F6 line, T1012, with improved resistance to Rice black-streaked dwarf virus (RBSDV) disease, controlled by quantitative trait loci (QTLs) qRBSDV-1 and qRBSDV-4, which could be valuable for breeding RBSDV-resistant rice cultivars . However, information specific to resistance to Scotinophara coarctata was not found in the provided contexts.

How to estimate resistant starch content in rice ?5 answersTo estimate resistant starch (RS) content in rice, various methods and techniques have been developed. One approach involves utilizing the Rice Quality Matrix (SQM) prediction model, which considers factors like microstructure, gelatinization temperature, total starch, amylose, and amylopectin to predict RS content. Another method involves measuring RS content in different Vietnamese rice accessions using the Megazyme kit and spectrophotometer, highlighting the diversity of RS content across rice varieties. Additionally, modifying starch synthase-related genes like SBE and SS3/SSIII in rice can enhance RS content, with mutations in these genes leading to significant increases in RS levels. Furthermore, a method for estimating polished rice amylose and RS content involves preparing polished rice flour, starch particles, and measuring rice flour gelatinization characteristics using RVA. These diverse approaches provide valuable insights into estimating RS content in rice for various applications.
What are the problems that rice farmers face in terms of pests like earhead bugs in bicol pilippines?5 answersRice farmers in Bicol, Philippines face challenges with pests like earhead bugs, which can significantly impact crop yields. These pests are a major concern in rice cultivation, causing yield losses ranging from 25-70% due to sap-sucking activities on developing grains. Insect problems are exacerbated in intensive rice cropping systems, with over 800 insect species affecting rice, although only a dozen are economically significant. To address these challenges, integrated pest management strategies, including the use of newer insecticide combinations, have shown promise in reducing pest populations and mitigating crop damage. Additionally, indigenous farmers in other regions have employed traditional and scientific knowledge to combat environmental, social, and agricultural technology system problems in rice field agroecosystems, highlighting the importance of a holistic approach to pest management.
What specific pheromone that the rice bug attract?5 answersThe specific pheromone that attracts the rice bug is 1,10-bisaboladien-3-ol, also known as zingiberenol. This pheromone has been identified in both Tibraca limbativentrisand Mormidea v-luteum. In Tibraca limbativentris, the male-produced sex pheromone is a 7:3 mixture of (3S,6S,7R)-1,10-bisaboladien-3-ol and (3R,6S,7R)-1,10-bisaboladien-3-ol. In Mormidea v-luteum, the male-specific compounds include two isomers of zingiberenol, along with other compounds like murgantiol and sesquipiperitol. These studies have shown that the female rice bugs are attracted to the pheromone compounds, indicating their role in chemical communication and potential use in pest management programs.
What are the impacts of rice black bug (RBB) infestation on smallholder farmers?5 answersRice black bug (RBB) infestation has significant impacts on smallholder farmers. In Thiruvallur and Kancheepuram districts, RBB caused a yield loss of 23% in susceptible rice cultivars. In sub-Saharan Africa, RBB is one of the biotic constraints severely affecting rice production systems, leading to reduced productivity and technical efficiency levels. Farmers in Cote d'Ivoire and Benin cope with RBB infestation through learning from experience, but it still hampers their technical efficiency. In Bangladesh, the routine application of insecticides for RBB control is not mandatory, as it was found that similar pest populations were observed even when insecticides were not applied. RBB infestation in rain-fed lowland rice fields in Benin has led to yield losses exceeding 60%, causing farmers to abandon heavily infested fields. Attack by Malayan black bugs on rice seedlings and panicles also significantly reduces plant growth and grain yield.
What is a rice bug?5 answersA rice bug is a type of insect pest that affects rice crops during the reproductive stage. It is known to cause significant damage to rice plants by sucking the plant sap directly and indirectly transmitting viruses. Rice bugs have been the focus of research and control methods due to their destructive nature and economic impact. Different species of rice bugs, such as Leptocorisa acuta and Leptocorisa chinensis, have been studied in terms of their distribution, hosts, natural enemies, and control strategies. The efficacy of various plant products and synthetic insecticides has been tested to manage rice bug infestations. The spread and invasion history of rice bugs, such as Lissorhoptrus oryzophilus, have been investigated, along with the development of comprehensive control strategies.
What is the state of the rice because of rice weevils in the Philippines?2 answersRice weevils have become a major pest in rice production in the Philippines, causing significant damage to rice crops. The golden apple snail, also known as "golden kuhol," was introduced to the Philippines in the 1980s and has since become a major pest in rice fields, infesting about 11% of the country's total rice-growing area. Weedy rice, a competitive weed that reduces growth resources for cultivated rice, is also a significant problem in rice production. Farmers in different regions of the Philippines have reported the presence of weedy rice species, such as Sphenoclea zeylanica Gaertn. and Fimbristylis quinquangularis (Vahl) Kunth., in their rice fields. The presence of weedy rice and the golden apple snail can lead to yield reduction and impact rice production in the country. Efforts to manage these pests and increase awareness among farmers about their impact on rice production are necessary to mitigate their negative effects.
