European Journal of Entomology, 2005 The semiochemical relationships in a predator-prey-host plant system were studied by a series of multiple-choice field assays. The studied system included predatory flies of the genus Medetera (Diptera: Dolichopodidae), the bark beetles Ips typographus ...

Knowing the Enemy: Inducible Defences in Freshwater Zooplankton
Diversity, 2020 Phenotypic plasticity in defensive traits is an appropriate mechanism to cope with the variable hazard of a frequently changing predator spectrum. In the animal kingdom these so-called inducible defences cover the entire taxonomic range from protozoans ...

Deciphering Plant-Insect-Microorganism Signals for Sustainable Crop Production
Biomolecules, 2023 Agricultural crop productivity relies on the application of chemical pesticides to reduce pest and pathogen damage. However, chemical pesticides also pose a range of ecological, environmental and economic penalties.

Field Attraction of the Vine Weevil Otiorhynchus sulcatus to Kairomones [PDF]
Journal of Economic Entomology, 2012 Root weevils in the genus Otiorhynchus are cited as one of the most important pests in the major nursery and small fruit production areas throughout the United States, western Canada, and northern Europe. A major problem in combating weevil attack is monitoring and timing of control measures.

Responses of Diabrotica speciosa to a semiochemical trap characteristics
Brazilian Archives of Biology and Technology, 2006 Responses of Diabrotica speciosa (Germar) (Coleoptera: Chrysomelidae) to a semiochemical trap characteristics were investigated in the field. The trap consisted of plastic bottles with several perforations (0.5 cm diameter and 2.0 cm distance each other)

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

Rapid habituation by mosquito larvae to predator kairomones [PDF]
Journal of Vector Ecology, 2014 Larvae of some species of mosquitoes have been shown to respond to water-borne kairomones from predators by reducing bottom-feeding and replacing it with surface filter-feeding, which uses less movement and is thus less likely to attract a predator. However, if no predator attack takes place, then it would be more efficient to use a risk allocation ...

Effectiveness of synthetic versus natural human volatiles as attractants for Anopheles gambiae (Diptera: Culicidae) sensu stricto [PDF]
, 2010 Females of the African malaria vector, Anopheles gambiae Giles sensu stricto, use human volatiles to find their blood-host. Previous work has shown that ammonia, lactic acid, and aliphatic carboxylic acids significantly affect host orientation and ...
