Aphid alarm pheromone produced by transgenic plants affects aphid and parasitoid behavior [PDF]

, 2006
The alarm pheromone for many species of aphids, which causes dispersion in response to attack by predators or parasitoids, consists of the sesquiterpene (E)-β-farnesene (Eβf).

Assessing pest control treatments from phenology models and field data

Pest Management Science, Volume 81, Issue 4, Page 1851-1859, April 2025.
Theoretical effect of two larvicide sprays, two delayed larvicide sprays that follow an oil treatment, mating disruption, and mating disruption plus four virus sprays on codling moth larva (brown for treated versus pink for untreated) and adult (dark green for treated versus light green for untreated) phenology.

The Ca2+/CaN/ACC and cAMP/PKA/HK signal pathways are required for PBAN-mediated sex pheromone biosynthesis in Conogethes punctiferalis

Journal of Integrative Agriculture
Conogethes punctiferalis is a crop and fruit pest that has caused serious economic losses to agricultural production. This pest relies heavily on its sex pheromone to ensure sexual encounters and subsequent mating success.

Field evaluation of synthetic aphid sex pheromone in enhancing suppression of aphid abundance by their natural enemies [PDF]

, 2016
The effects of lures containing aphid sex pheromone components (4aS,7S,7aR)-nepetalactone and (1R,4aS,7S,7aR)-nepetalactol on abundance of pea aphid, Acyrthosiphon pisum Harris, aphid parasitoids, predators and hyperparasitoids in alfalfa fields were ...

Building Blocks as Experiences in Dynamic Capacitated Arc Routing Problems

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT The dynamic capacitated arc routing problem (DCARP) aims to update the service paths of vehicles in the capacitated arc routing problem when uncertain factors deteriorate the current schedule of vehicles' services. A DCARP scenario comprises a series of DCARP instances that share similarities with each other. Therefore, optimisation experience

Signaling mechanisms and behavioral function of the mouse basal vomeronasal neuroepithelium

Frontiers in Neuroanatomy, 2014
The vomeronasal organ (VNO) is a sensory organ that is found in most terrestrial vertebrates and that is principally implicated in the detection of pheromones.

Attraction range of a sex pheromone trap for the damson-hop aphid Phorodon humuli (Hemiptera: Aphididae)

, 2017
The attraction range of olfactory response by winged female gynoparae (autumn migrants that give birth to oviparae, the sexual females) and male damson–hop aphids Phorodon humuli (Schrank) is investigated in field experiments over 2 years by analyzing ...

Naïve ants reach a food source quicker when encountering returning ants

Scientific Reports
Pheromone guidance of ant foraging activity is well described, but less is known about how the presence of inward ant traffic on the trail affects the behavior of naive nestmates and if these influences are dependent or independent of pheromone signaling.

Structure elucidation of some insect pheromones : a contribution to the development of selective pest control agents

, 1977
The use of pheromones is one of the methods currently being investigated intensively as an alternative method of insect control. The various ways in which pheromones might be used in insect control programmes are briefly discussed in Chapter 1.Chapter 2 ...

Nasonov pheromone of the honey bee, apis-mellifera l (hymenoptera, apidae) .1. Chemical characterization

, 1980
Composition of the Nasonov pheromone of the honey bee has been reexamined using new procedures, including analysis of pheromone from single live insects by capillary column GC-MS. Two new components have been identified, nerol and (E,E)-farnesol, and the
