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 ...

Jumping performance of planthoppers (Hemiptera, Issidae) [PDF]
Journal of Experimental Biology, 2009 SUMMARYThe structure of the hind limbs and the kinematics of their movements that propel jumping in planthopper insects (Hemiptera, Auchenorrhyncha,Fulgoroidea, Issidae) were analysed. The propulsion for a jump was delivered by rapid movements of the hind legs that both move in the same plane beneath the body and parallel to its longitudinal axis, as ...

Development of an Artificial Liquid Diet for Allelochemical Delivery in Lycorma delicatula
Journal of Applied Entomology, EarlyView.ABSTRACT Spotted lanternfly, Lycorma delicatula White (Hemiptera: Fulgoridae), is an invasive phloem‐feeding planthopper native to Asia, which poses a growing threat to US agriculture due to its broad host range and rapid spread since its 2014 detection. To better understand how L.

Genetics of field resistance of rice to brown planthopper
, 1987 The brown planthopper [Nilaparvata lugens (Stal)] is one of the most serious insect pests of rice (Oryza sativa L.) in South and Southeast Asia. Because cultivars with vertical resistance to brown planthopper have "broken down" due to brown planthopper ...

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 ...

Journal of Applied Entomology, EarlyView.ABSTRACT The planthopper Pentastiridius leporinus (Hemiptera: Cixiidae) is the primary vector of two phloem‐restricted prokaryotes, which can cause the disease syndrome de basses richesses (SBR) in sugar beet (Beta vulgaris L.). Heavy infestations of this insect have contributed to significant yield losses in Central Europe, but little is known about ...

A Cripavirus in the brown planthopper, Nilaparvata lugens
Journal of General Virology, 2016 A Cripavirus-like long unique sequence was identified during transcriptome sequencing of the brown planthopper (BPH), Nilaparvata lugens. This unique sequence demonstrated high similarity with the whole-genome sequence of cricket paralysis virus, including 5' and 3' untranslated regions; thus we considered it the whole genome of a new virus. We propose
