Extraordinary morphological changes in valve morphology during the ontogeny of several species of the Australian ostracod genus Bennelongia (Crustacea, Ostracoda)

open access: yesEuropean Journal of Taxonomy, 2013
Ostracods belonging to the genus Bennelongia differ much in valve morphology between adults and juveniles. Adult valves are asymmetrical, characterised by a beak-like feature in the antero-ventral region of the left valve, and, with some notable ...

Potential Protein and Biodiesel Sources from Black Soldier Fly Larvae: Insights of Larval Harvesting Instar and Fermented Feeding Medium

open access: yesEnergies, 2019
Primarily produced via transesterification of lipid sources, fatty acid methyl ester (FAME) of biodiesel derived from insect larvae has gained momentum in a great deal of research done over other types of feedstock.

Moulting pattern and mortality during the final emergence of the Coromandel Marsh Dart Damselfly Ceriagrion coromandelianum (Zygoptera: Coenagrionidae) in central India

open access: yesJournal of Threatened Taxa, 2019
The final emergence of the Coromandel Marsh Dart Damselfly Ceriagrion coromandelianum was studied for 50 days (22 January–12 March, 2011) from the botanical garden of Hislop College, Nagpur, India, (a semi controlled site) where small underground cement ...

SUPERNUMERARY LARVAL INSTARS IN CYCLORRHAPHOUS DIPTERA

open access: yesThe Biological Bulletin, 1972
1. The developmental program for metamorphosis is determined in third instar larvae of Calliphora and Sarcophaga very early after ecdysis. The process is activated by feeding and can be delayed for many days by starvation.2. High doses of ecdysterone (20 µg per larva) injected just after ecdysis or in starved larvae cause a precocious molt and the ...

Plant Virus‐Induced Inheritable Apoptosis Drives Reproductive Costs in Female Insect Vectors to Balance Viral Biparental Transmission

open access: yesAdvanced Science, EarlyView.
Rice gall dwarf virus (RGDV), transmitted biparentally by leafhopper vector to their offspring, exploits the capsid protein to induce inheritable ovarian apoptosis via insulin‐driven PI3K/AKT/FoxO signaling axis. This mechanism enhances infection but reduces female reproductive fitness, causing inefficient maternal transmission.

Stabilized Ion Selectivity Corrects Activation Drift in Kalium Channelrhodopsins

open access: yesAdvanced Science, EarlyView.
As newly emerged optogenetic tools, potassium channelrhodopsins (KCRs) can drift from inhibition to activation during illumination as K⁺ selectivity declines. It is shown that both the absolute K⁺/Na⁺ permeability ratio and its stability over time govern this drift, identify KCR1‐C29D as a reliably inhibitory variant, and outline design principles for ...

Context-Dependent Anti-Predator Behavior in Nymphs of the Invasive Spotted Lanternfly (Lycorma delicatula): Effects of Development, Microhabitat, and Social Environment

open access: yesInsects
Antipredator behaviors in animals often vary with developmental stage, microhabitat, and social context, yet few studies examine how these factors interact in species that undergo ontogenetic shifts in chemical defense.
