Responses of Fruit Flies (Diptera: Tephritidae) to Protein Bait Applied at Different Densities

Journal of Applied Entomology, EarlyView.
ABSTRACT The effectiveness of odour‐based lures for insects is related to their active space, the air volume around an odour source in which an insect will detect and move towards it. This principle applies to protein baits laced with toxicants that are used as either sprays or stations to suppress pest fruit fly populations.

Characterisation of Sex Pheromone and Genetic Strain in Rachiplusia nu (Lepidoptera: Noctuidae) Populations Across Brazil

Journal of Applied Entomology, EarlyView.
ABSTRACT Rachiplusia nu, known as the sunflower looper (SFL) and belonging to the Plusiinae subfamily, is a major defoliator of soybeans, sunflowers and other horticultural crops across southern South America. This species has recently expanded to central and northern regions of Brazil, becoming a key soybean pest.

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 ...

Daily Rhythms of Sex Pheromone Emission and Courtship Behaviour in the Neotropical Brown Stink Bug Euschistus heros

Journal of Applied Entomology, EarlyView.
ABSTRACT Understanding the chemical and behavioural ecology of the Neotropical brown stink bug, Euschistus heros (Hemiptera: Pentatomidae), is essential for developing effective integrated pest management (IPM) strategies in South American soybean production. This study investigated the courtship behaviour and diel periodicity of sex pheromone emission.

Conspecific cueing or cooperative feeding?—Foraging stable flies are visually attracted to conspecific flies

Medical and Veterinary Entomology, EarlyView.
In two‐choice laboratory bioassays, food‐deprived and CO2‐stimulated stable flies were offered paired landing platforms that were baited or not (control) with conspecific flies. The presence of conspecifics prompted the attraction and landing of foraging stable flies.

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.

Ecología química y perspectivas de su aplicación en la conservación de la biodiversidad [PDF]

, 2013
Chemical ecology comprises the study of interactions of organisms with their environment that are mediated by the chemicals they produced. In general, chemicals that mediate interactions between organisms are called semiochemicals.

Aboveground and Belowground Insect Herbivory Changes Maize‐Wireworm Interactions via Root Volatile Cues

Plant, Cell &Environment, EarlyView.
ABSTRACT The rhizosphere harbours critical plant‐herbivore interactions often mediated by small lipophilic molecules (SLMs). Despite the agricultural importance of many soil‐dwelling insects, surprisingly little is known about chemically mediated belowground crop‐pest interactions. Root and shoot herbivores can influence these interactions by modifying
