Solar wind protons at 1 AU: trends and bounds, constraints and correlations

open access: yes, 2014
The proton temperature anisotropy in the solar wind exhibits apparent bounds which are compatible with the theoretical constraints imposed by temperature-anisotropy driven kinetic instabilities.

Transgenic cowpeas (Vigna unguiculata L. Walp) expressing Bacillus thuringiensis Vip3Ba protein are protected against the Maruca pod borer (Maruca vitrata) [PDF]

open access: yesPlant Cell, Tissue and Organ Culture (PCTOC), 2017
Although cowpea is an important food security crop in Africa, its production is constrained by insect pests such as the legume pod borer (Maruca vitrata) (Lepidoptera). Potential control strategies have focussed on using insecticidal toxins such as the crystal Cry proteins and vegetative insecticidal proteins (Vips) encoded by the cry and vip genes ...

Application of insulin signaling to predict insect growth rate in Maruca vitrata (Lepidoptera: Crambidae). [PDF]

open access: yesPLoS ONE, 2018
Insect growth is influenced by two major environmental factors: temperature and nutrient. These environmental factors are internally mediated by insulin/insulin-like growth factor signal (IIS) to coordinate tissue or organ growth.

Population Genetic Differentiation and Structure of Maruca vitrata (Lepidoptera: Crambidae) in India

open access: yesDiversity, 2022
Maruca vitrata is one of the primary biotic constraints for pigeon pea production in India. The present study assessed the genetic variation and population structure of M.

A Parallel-Propagating Alfv\'enic Ion-Beam Instability in the High-Beta Solar Wind

open access: yes, 2013
We investigate the conditions under which parallel-propagating Alfv\'en/ion-cyclotron waves are driven unstable by an isotropic ($T_{\perp \alpha} = T_{\parallel\alpha}$) population of alpha particles drifting parallel to the magnetic field at an average

Relative drifts and temperature anisotropies of protons and $\alpha$ particles in the expanding solar wind -- 2.5D hybrid simulations

open access: yes, 2014
We perform 2.5D hybrid simulations to investigate the origin and evolution of relative drift speeds between protons and $\alpha$ particles in the collisionless turbulent low-$\beta$ solar wind plasma.

Physiological Alterations in Deletion Mutants of Two Insulin-Like Peptides Encoded in Maruca vitrata Using CRISPR/Cas9

open access: yesFrontiers in Physiology, 2021
Most insect species encode multiple insulin-like peptides (ILPs) that exhibit functional overlaps in mediating physiological processes such as development and reproduction. Why do they need multiple ILPs?

A zone of preferential ion heating extends tens of solar radii from Sun

open access: yes, 2017
The extreme temperatures and non-thermal nature of the solar corona and solar wind arise from an unidentified physical mechanism that preferentially heats certain ion species relative to others.

Role of morphological factors of pigeonpea in imparting resistance to spotted pod borer, Maruca vitrata Geyer (Lepidoptera: Crambidae) [PDF]

open access: yes, 2016
Morphological characters of eleven test genotypes of pigeonpea, such as growth habit, pubescence of pods and leaves, pod angle and pod wall thickness were studied in order to work out the relationship of these traits vis-à-vis resistance/susceptibility ...

open access: yesJournal of Asia-Pacific Biodiversity
Nine species of Crambidae are reported for the first time from the Federated States of Micronesia: Glyphodes multilinealis Kenrick, 1907, Diaphania indica (Saunders, 1851), Maruca vitrata (Fabricius, 1787), Sameodes cancellalis (Zeller, 1852), Omiodes ...
