Pheromone Guidance of Polarity Site Movement in Yeast

Biomolecules, 2022
Cells’ ability to track chemical gradients is integral to many biological phenomena, including fertilization, development, accessing nutrients, and combating infection. Mating of the yeast Saccharomyces cerevisiae provides a tractable model to understand

Genetic control of conventional and pheromone-stimulated biofilm formation in Candida albicans.

PLoS Pathogens, 2013
Candida albicans can stochastically switch between two phenotypes, white and opaque. Opaque cells are the sexually competent form of C. albicans and therefore undergo efficient polarized growth and mating in the presence of pheromone.

Oviposition Behavior of Indianmeal Moths With and Without Synthetic Pheromone [PDF]

, 2018
Plodia interpunctella, commonly known as the Indianmeal moth, is a pyralid moth that is a pest of stored food products (Mohandrass, 2007). While there are many known factors that influence oviposition, like food odor and type of food available ...

Information Transmission Strategies for Self‐Organized Robotic Aggregation

Advanced Robotics Research, EarlyView.
In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.

Gonadotropin-Releasing Hormone Modulates Vomeronasal Neuron Response to Male Salamander Pheromone

Journal of Experimental Neuroscience, 2012
Electrophysiological studies have shown that gonadotropin-releasing hormone (GnRH) modifies chemosensory neurons responses to odors. We have previously demonstrated that male Plethodon shermani pheromone stimulates vomeronasal neurons in the female ...

Effectiveness of Various Solar Light Traps With and Without Sex Pheromone for Mass Trapping of Tomato Leaf Miner (Tuta absoluta) in a Tomato Field

Notulae Scientia Biologicae, 2018
Tuta absolute was a quarantine pest in Iran that has been recorded for the first time in 2009. The most conventional methods for control of this pest in Iran are chemical methods and mass trapping, although the efficiency of the latter method is not ...

Identification and Characterization of an Antennae-Specific Glutathione S-Transferase From the Indian Meal Moth

Frontiers in Physiology, 2021
Insect glutathione-S-transferases (GSTs) play essential roles in metabolizing endogenous and exogenous compounds. GSTs that are uniquely expressed in antennae are assumed to function as scavengers of pheromones and host volatiles in the odorant detection

Degradable and Recyclable 3D‐Printed Pheromones Delivery System Reinforced by Metal Coordination Cross‐Linking for Efficient Pest Trapping

Advanced Science, EarlyView.
This study presents a 3D‐printed carrier for the slow release of insect pheromones. Reinforced by lignosulfonate and Fe³⁺ coordination in a cellulose acetate matrix, it enables sustained release for up to six weeks with remarkable trapping efficacy. Featuring soil degradability and recyclable re‐printing capability, this carrier provides a sustainable ...

A Cold Stress‐Activated Endocrine Sentinel Chemical Hormone Promotes Insect Survival via Mitochondrial Adaptations Through the Adipokinetic Hormone Receptor

Advanced Science, EarlyView.
Seasonal cold adaptation is vital for insect survival, yet the molecular mechanisms linking diapause to mitochondrial resilience remain largely unresolved. We identify ascaroside C9 (asc‐C9) as a key endocrine signal that enhances diapause survival during cold stress by activating the AKHR–PGC1α–UCP4 axis, thereby driving cold‐induced lipolysis and ...
