THE EFFECT OF SOAKING DURATION OF TUBA ROOTS (Derris elliptica) ON THE MORTALITY OF THE WHITE-BACKED PLANTHOPPER PESTS (Metcalfa pruinosa)

open access: yesJurnal Pendidikan Matematika dan IPA
Tuba root (Derris elliptica) is a plant that contains rotenone in roots where this content functions as a poison for insects, so tuba root has the opportunity to be used as a vegetable pesticide in pest control activities.

Decoding MAPK cascades in plant immunity: Activation, regulation, integration, and pathogen manipulation

open access: yesJournal of Integrative Plant Biology, EarlyView.
This review focuses on mitogen‐activated protein kinase (MAPK) activation and summarizes how plants regulate and integrate MAPK signaling in modulating plant immune responses. It also examines the effectors pathogens have evolved to manipulate MAPK activation and thereby inhibit plant immunity.

Jumping performance of planthoppers (Hemiptera, Issidae) [PDF]

open access: yesJournal 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 ...

A Comparative Analyses of the Complete Mitochondrial Genomes of Fungal Endosymbionts in Sogatella furcifera, White-Backed Planthoppers

open access: yesInternational Journal of Genomics, 2021
Sogatella furcifera Horvath, commonly known as the white-backed planthoppers (WBPH), is an important pest in East Asian rice fields. Fungal endosymbiosis is widespread among planthoppers in the infraorder Fulgoromorpha and suborder Auchenorrhyncha.

The multifaceted regulatory network of microRNA396: Orchestrating plant plasticity through coordinating development and various stresses

open access: yesJournal of Integrative Plant Biology, EarlyView.
This review examines the character and function of the microRNA miR396, which helps plants balance growth, reproduction, regeneration, and survival under various stresses, highlighting recent progress and evidence that this pathway shapes crop yield, pest and disease resistance, and tissue regeneration, making it a promising target for precision crop ...

Studies on the Diapause in the Planthoppers

open access: yesJapanese 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 ...

OsMYB306‐OsRAV11 Regulates Resistance of Rice to Striped Stem Borer by Modulating Serotonin Biosynthesis

open access: yesPlant 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 ...

A reovirus in the brown planthopper, Nilaparvata lugens

open access: yesJournal 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 ...

Negative Regulators of Rice Agronomic Traits: Functional Insights and Applications in Genome Editing‐Based Breeding

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Rice is the staple crop for more than half of the global population, and improving grain yield, grain quality, and stress resistance remain central goals of modern rice breeding. Among current precision breeding strategies, genome editing has created new opportunities for crop improvement, but its success depends heavily on the selection of ...
