Odorant receptor phylogeny confirms conserved channels for sex pheromone and host plant signals in tortricid moths

Ecology and Evolution, 2020
The search for mates and food is mediated by volatile chemicals. Insects sense food odorants and sex pheromones through odorant receptors (ORs) and pheromone receptors (PRs), which are expressed in olfactory sensory neurons.

Trap attributes influencing capture of Diabrotica speciosa (Coleoptera: Chrysomelidae) on common bean fields Atributos da armadilha influenciam captura de Diabrotica speciosa (Coleoptera: Chrysomelidae) em feijoeiro

Scientia Agricola, 2005
Refinements in trap characteristics may improve ability to monitor and mass-trap beetles. Field assays were conducted in common bean fields to assess responses of Diabrotica speciosa (Germar) to some trap characteristics.

Synthetic blends of volatile, phytopathogen-induced odorants can be used to manipulate vector behavior [PDF]

, 2014
Volatile organic compounds (VOCs) are emitted from all plants and these VOCs are important means of communication between plants and insects. It has been documented that pathogen infections alter VOC profiles rendering infected plants more attractive to ...

Feeding and arrestment responses of Diabrotica speciosa to cucurbitacin-content formulations Respostas alimentares e arrestantes de Diabrotica speciosa a formulações contendo cucurbitacina

Pesquisa Agropecuária Brasileira, 2005
The objective of this work was to evaluate arrestant and stimulant feeding effects on Diabrotica speciosa (Ger.), using cucurbitacin-content starch-based formulations prepared with varying starch sources, and adding potassium lignate.

Detection of oviposition-deterring larval tracks in Chrysopa oculata and Chrysopa perla (Neuroptera: Chrysopidae)

European Journal of Entomology, 2010
We investigated the ability of females of the aphidophagous chrysopids Chrysopa oculata and Chrysopa perla to distinguish clean substrates from substrates with tracks of chrysopid first instars after ablation of various sensory organs potentially ...

Influence of physicochemical factors on environmental availability and distribution of semiochemicals that affect Varroa destructor and phylogenetically close organisms: classification by VHWOC PCA-clustering

Heliyon, 2019
Varroa destructor parasites Apis mellifera larvae following the interception of the semiochemicals involved in bee communication; thus, the semiochemical availability and distribution pathways take place within different physicochemical environments. The

MANAGEMENT OF STRAWBERRY BLOSSOM WEEVIL AND EUROPEAN TARNISHED PLANT BUG IN ORGANIC STRAWBERRY AND RASPBERRY USING SEMIOCHEMICAL TRAPS “Softpest Multitrap” [PDF]

, 2013
Many European growers of organic strawberry and raspberry have large losses in yield (sometimes >80%) and reduced quality of their products because of insect damage.

Genetic Characterization and Mating Disruption in Spodoptera Species, a Case Study on Spodoptera frugiperda (Lepidoptera, Noctuidae): A Systematic Review

Insects
The genus Spodoptera (Lepidoptera: Noctuidae) includes several agricultural pests that cause major losses in global crop production and threaten food security, notably Spodoptera frugiperda (J.E. Smith, 1797), an invasive pest that is difficult to manage.
