1. Danish Validation of a Retronasal Olfactory Powder Test and Development of a Novel Quick Retronasal Olfactory Test
Abstract Introduction Quality of life is closely linked to retronasal olfactory function. Familiarity with odors vary, so tests need validation. Testing can be time-consuming, so a quick test and a thorough test are needed for clinical and research settings. Objectives The objectives of this study were to validate the original retronasal powder olfactory t

2. Adaptation of the Pediatric Smell WheelTM to evaluate olfactory function in Brazilian children
Abstract Objective: Olfaction influences nutrition, safety, and the cognitive development of children. Presently there are few olfactory tests for children, and normative reference values are generally lacking. In this study, we validate the Pediatric Smell WheelTM (PSW) to evaluate olfactory function in Brazilian children. Methods: We modified and validat

3. Preference of Neoseiulus californicus (Acari: Phytoseiidae) for volatiles of Bt maize induced by multiple herbivory
ABSTRACT Plant indirect induced defenses against herbivores are characterized by the production of plant volatiles that to attract natural enemies. The objective of this study was to evaluate whether the attack of the two-spotted spider mite Tetranychus urticae or the multiple herbivory of T. urticae together with the fall armyworm Spodoptera frugiperda are

4. Laboratório Sensorial: uma proposta de ativação do corpo
Este artigo apresenta um ensaio poético-fotográfico sobre o Laboratório Sensorial, um dispositivo do projeto de extensão universitária Expressão e Transformação, vinculado ao Instituto de Psicologia da Universidade Federal do Rio de Janeiro, Brasil (UFRJ). Inspirado na Fenomenologia e na Arte Contemporânea, o laboratório é uma proposta de sensibil

5. Sensory descriptors of cocoa beans from cultivated trees of Soconusco, Chiapas, Mexico
The odor and taste profile of cocoa bean samples obtained from trees cultivated in southern Mexico were evaluated by trained panelists. Seven representative samples (groups) of a total of 45 were analyzed. Four attributes of taste (sweetness, bitterness, acidity and astringency), and nine of odor (chocolate, nutty, hazelnut, sweet, acidity, roasted, spicy, m

6. Odor from anaerobic digestion of swine slurry: influence of pH, temperature and organic loading
Farm slurry management from storage and/or treatment is the main source of odors from swine production, which are determined by factors such as operational variations (organic loading), cleaning of facilities and animal diet (pH) or environmental conditions (temperature). The aim of this study was to evaluate the influence of pH, temperature and organic load

7. First experimental evidence that a harvestman (Arachnida: Opiliones) detects odors of non-rotten dead prey by olfaction
Harvestmen feed on live, dead and fresh, or decomposing animals, fungi, and plant matter, being very dependent on chemoreception to find food. Herein we performed an experiment to test if individuals of Discocyrtus pectinifemur Mello-Leitão, 1937 (Gonyleptidae) (n = 23) behave differently when in contact with olfactory cues from different sources (rotten pr

8. Interações entre Protodiscelis (Colletidae, Neopasiphaeinae) e plantas aquáticas e a importância de odores florais na atração de polinizadores. / Interactions between bees of Protodiscelis (Colletidae, Neopasiphaeinae) and aquatic plants, and the importance of odors to locating flowers.
Abelhas são os principais polinizadores das plantas com flores. Plantas são sésseis e a reprodução sexuada cruzada somente ocorre através de vetores de pólen. Sendo assim, flores zoofílicas provêm pistas para o encontro interespecífico, são polinizadas e fornecem recursos florais aos polinizadores. O principal recurso coletado por abelhas herbívo

9. Reproductive behaviours and host plant selection mediated by semiochemicals in Neoleucinodes elegantalis (Lepidoptera: Crambidae) / Comportamento reprodutivo e seleção de hospedeiro mediada por semioquímicos em Neoleucinodes elegantalis (Lepidoptera: Crambidae)
The searching behaviour in insects is important to acquire food, meeting mates, oviposition sites location and protect the insects against predators. Thus, the majority of herbivorous insects select their host plant and, in particular, the plants part, which it will feed and oviposit on, using, among other tools, host plants semiochemicals. This paper aims:

10. The neurobiology of infant maternal odor learning
Infant rats must learn to identify their mother’s diet-dependent odor. Once learned, maternal odor controls pups’ approach to the mother, their social behavior and nipple attachment. Here we present a review of the research from four different laboratories, which suggests that neural and behavioral responses to the natural maternal odor and neonatal lear

11. Sensory response of the egg parasitoid Telenomus podisi to stimuli from the bug Euschistus heros.
The objective of this work was to study the foraging behavior of Telenomus podisi Ashmead (Hymenoptera: Scelionidae) in the presence of stimuli from its host, Euschistus heros (Heteroptera: Pentatomidae). The stimuli selected were: egg mass; virgin males and females; volatile extracts of sexually mature males and females; components of male sex pheromone; a
