Studies on exploiting semiochemicals for pest management in organic farming systems OF0188 [PDF]

, 2000
This study addresses the extent to which pest management systems can exploit semiochemicals (defined below) in ways acceptable to organic farming, and determines where the science base needs to be expanded to accommodate specific problems arising in an ...

Experimental Assessment of the Effects of Substrate Choice on the Duration of Chemical Signals in Fecal Scent‐Marks of Free‐Ranging Iberian Wolves

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Chemical communication, typically based on feces, urine, and glandular secretions, often deposited as substrate scent marks, plays a key role in social organization and communication among many mammals, especially carnivores. This study assesses experimentally whether the type of substrate chosen for fecal deposition and the temperature ...

Management of strawberry blossom weevil and European tarnished plant bug in organic strawberry and raspberry using semiochemical traps [PDF]

, 2012
The strawberry blossom weevil (Anthonomus rubi) and the European tarnished plant bug (Lygus rugulipennis) cause large (10 - >80%) losses in yield and quality in organically grown berries.

Novel use of stir bar sorptive extraction (SBSE) as a tool for isolation of oviposition site attractants for gravid Culex quinquefasciatus [PDF]

, 2009
Mosquitoes such as Culex quinquefasciatus Say (Diptera: Culicidae) are important vectors of organisms that cause disease in humans. Research into the development of effective standardized odour baits for blood-fed females (oviposition attractants), to ...

Sanitary Logging in the Monarch Butterfly Biosphere Reserve: One Problem, One Legislation but Different Criteria and Different Treatments

Land Degradation &Development, EarlyView.
ABSTRACT Bark beetles are small insects that inhabit the bark of trees. When their population increases excessively, they can weaken the trees and cause their death. In México, federal regulations obligate forest landowners to carry out sanitary logging to control bark beetle outbreaks in adherence to official procedures.

Colonization and spatiotemporal distribution of bruchid pests in lentil and faba bean fields

Pest Management Science, EarlyView.
This study of 104 fields identifies Bruchus signaticornis in lentils and B. rufimanus in faba beans as the sole grain‐damaging species. Their uniform distribution within fields and the strong effect of regulatory factors on larvae and egg survival emphasize the need for species‐specific, phenology‐based and spatially informed integrated pest management

Measuring Microbiome Effectiveness: A Role for Ingestible Sensors

Gastrointestinal Disorders, 2020
Across the world there is an increasingly heavy burden of noncommunicable diseases related to obesity, mental health, and atopic disease. In a previous publication, we followed the developing idea that that these conditions arise as our microbiome loses ...

Bile Salts as Semiochemicals in Fish [PDF]

Chemical Senses, 2014
Bile salts are potent olfactory stimuli in fishes; however the biological functions driving such sensitivity remain poorly understood. We provide an integrative review of bile salts as semiochemicals in fish. First, we present characteristics of bile salt structure, metabolism, and function that are particularly relevant to chemical communication. Bile
