Studies on the Diapause in the Planthoppers
Japanese Journal of Applied Entomology and Zoology, 1958 1) ヒメトビウンカ幼虫を初令から20∼22°Cで種々な日長の下に飼育した。2) 日長が8∼10時間では休眠率は100%になるが,日長がこの範囲からはずれると休眠率は減少する。12時間では約35%の非休眠個体を生じ,14時間ではすでに100%非休眠となる。全期間暗黒状態では約18%の休眠率となる(第1図,第2図)。3) 休眠した個体は4令期間が延びるが,同じ条件下でも徐々ながら発育し,4令期間の個体変異は非常に大きい。休眠個体と非休眠個体との区別は,少なくとも発育日数からは明白にはつけにくい。4) 休眠に入った幼虫も日周期に対する感受性をもっており,長日や極端な短日下では急速に発育を始め,かなり斉一な羽化が見られる。最も長い休眠状態は休眠誘起に好適な日長下で維持される ...

A reovirus in the brown planthopper, Nilaparvata lugens
Journal of General Virology, 1991 A new virus, belonging to the reovirus group, was found in an apparently healthy colony of the brown planthopper, Nilaparvata lugens, and was referred to as the Nilaparvata lugens reovirus (NLRV). The virus was found in the cytoplasm of the insect cells, sometimes associated with tubular structures, which is one of the characteristic features in ...

Plant Biotechnology Journal, EarlyView.ABSTRACT Striped stem borer (SSB; Chilo suppressalis Walker) is one of the most destructive pests in rice production. Previous studies have demonstrated that SSB infestation induces transcription of OsT5H (tryptamine‐5‐hydroxylase) and biosynthesis of serotonin, a newly recognised phytohormone, and that disruption of serotonin biosynthesis ...

Future planthopper management: increasing the resilience of rice systems
, 2014 The problem of planthoppers in rice—the causes of planthopper outbreaks and the ways of reducing the likelihood of this happening—is determined by the dynamic interaction between features of the natural system and decisions made in the human use system ...

Deep CNN-Based Planthopper Classification Using a High-Density Image Dataset
, 2023 Rice serves as the primary food source for nearly half of the global population, with Asia accounting for approximately 90% of rice production worldwide. However, rice farming faces significant losses due to pest attacks. To prevent pest infestations, it
