Physiological state of female and light intensity affect the host-plant selection of carrot psyllid, Trioza apicalis (Hemiptera: Triozidae)

open access: yesEuropean Journal of Entomology, 2008
We have studied the effect of different light gradient regimes on host-plant selection of the carrot psyllid, Trioza apicalis Förster. In both a strong and a weak light gradient, carrot psyllids preferred a carrot leaf placed in higher light intensity ...

Pheromones [PDF]

open access: yesCurrent Biology, 2017
The reality of invisible chemical signals, pheromones, between members of the same species was recognized long before they could be identified. Charles Darwin proposed that the breeding season sexual smells of male crocodiles, goats and other animals, too, could have evolved by sexual selection of the smelliest males through female choice. But it's not

Effect of trail bifurcation asymmetry and pheromone presence or absence on trail choice by Lasius niger ants [PDF]

open access: yes, 2014
During foraging, ant workers are known to make use of multiple information sources, such as private information (personal memory) and social information (trail pheromones).

The influence of evaporated pheromone upon the trapping of the spruce bark beetle - Ips typographus (L.) (Coleoptera: Curculionidae: Scolytinae) - Short communication

open access: yesJournal of Forest Science, 2017
This article examines the relative efficacy of releasing a larger pheromone plume volume and the relative efficacy of the number of pheromone dispensers within baited traps in trapping the spruce bark beetle.

Ant colony optimization and its application to the vehicle routing problem with pickups and deliveries [PDF]

open access: yes, 2009
Ant Colony Optimization (ACO) is a population-based metaheuristic that can be used to find approximate solutions to difficult optimization problems. It was first introduced for solving the Traveling Salesperson Problem. Since then many implementations of

An ant colony genetic fusion routing algorithm based on soft define network

open access: yesIET Networks, EarlyView., 2022
Abstract Aiming at the problem that there are many paths in data forwarding in soft define network (SDN) network, and the optimal path is difficult to find, combined with the advantages of ant colony algorithm and Genetic algorithm (GA), a routing control strategy based on the ant colony genetic fusion algorithm is proposed.

An efficient optimization algorithm for electric vehicle routing problem

open access: yesIET Power Electronics, EarlyView., 2023
1. To minimize the cost of travel and travel time for electric vehicles (EVs) while considering constraints on battery capacity, charging time, and delivery/pickup requirements. 2. To find the most efficient route to charging stations to address the issue of range anxiety and the scarcity of charging infrastructure. 3.

Optimization of the sex pheromone-based method for trapping field populations of Phthorimaea operculella (Zeller) in South China

open access: yesJournal of Integrative Agriculture, 2021
Despite the identification of the potato tuber moth Phthorimaea operculella (Zeller) sex pheromone, no effective application based on this pheromone has yet been developed and evaluated.

Effect of Collection Month, Visible Light, and Air Movement on the Attraction of Male Agriotes obscurus L. (Coleoptera: Elateridae) Click Beetles to Female Sex Pheromone

open access: yesInsects, 2020
Elaterid female sex pheromone, while currently used for monitoring the adult life stage (click beetle), has only recently been explored as a potential management tool.
