Advancement in Studies on the Virulent of Brown Planthopper
Brown planthopper (Nilaparvata lugens Stål, Homoptera: Delphacidae) is economically important pest on rice that feed directly or serve as vectors of pathogenic microorganisms and viruses to crops, resulting in significant damage and yield losses for farmers. In recent decades, brown planthopper has become notorious due to the emergence of new, virulent populations that can overcome host resista...
متن کاملBrown Planthopper (N. lugens Stal) Feeding Behaviour on Rice Germplasm as an Indicator of Resistance
BACKGROUND The brown planthopper (BPH) Nilaparvata lugens (Stal) is a serious pest of rice in Asia. Development of novel control strategies can be facilitated by comparison of BPH feeding behaviour on varieties exhibiting natural genetic variation, and then elucidation of the underlying mechanisms of resistance. METHODOLOGY/PRINCIPAL FINDINGS BPH feeding behaviour was compared on 12 rice vari...
متن کاملDifferential gene expression in response to brown planthopper feeding in rice.
Plant responses to herbivores are complex. 108 cDNA clones representing genes relating to plant responses to chewing insect-feeding, pathogen infection, wounding and other stresses were collected. Northern blot and cDNA array analysis were employed to investigate gene expression regulated by piercing-sucking insect, brown planthopper (BPH), Nilaparvata lugens (Homoptera: Dephacidae) on both the...
متن کاملThe Feeding Habits of Mesosauridae
Mesosauridae comprises the oldest known aquatic amniotes which lived in Gondwana during the Early Permian. Previous work in the Uruguayan mesosaur-bearing Mangrullo Formation suggested that mesosaurids lived in an inland water body, inferred as moderately hypersaline, with exceptional preservational conditions that justified describing these strata as a Fossil-Lagerstätte. Exquisitely preserved...
متن کاملsurvey on the rule of the due & hindering relying on the sheikh ansaris ideas
قاعده مقتضی و مانع در متون فقهی کم و بیش مستند احکام قرار گرفته و مورد مناقشه فقهاء و اصولیین می باشد و مشهور معتقند مقتضی و مانع، قاعده نیست بلکه یکی از مسائل ذیل استصحاب است لذا نگارنده بر آن شد تا پیرامون این قاعده پژوهش جامعی انجام دهد. به عقیده ما مقتضی دارای حیثیت مستقلی است و هر گاه می گوییم مقتضی احراز شد یعنی با ماهیت مستقل خودش محرز گشته و قطعا اقتضاء خود را خواهد داشت مانند نکاح که ...
