| The brown stink bug, Euschistus servus (Say), is abundant throughout most of eastern North America and is commonly found feeding on soybean, mullein, beans, tomatoes, peas, cotton, wheat, corn, tobacco and peach. Color change in E. servus from green to reddish-brown was shown to be an indicator of reproductive diapause. Reddish-brown insects lived longer than green individuals, females laid no eggs, and males did not produce pheromone. The high mortality registered for the green colony of E. servus adults was associated with the physiological cost associated with reproduction. The main pheromone component of this species is methyl 2E,4Z-decadienoate, in agreement with previous work. The first generation of this species develops on noncrop hosts and the... |

| The bee species of the Apinae, in addition to the thoracic salivary glands, possess a pair of cephalic glands originating as branches of the excretory duct that crosses the head. These glands are known as cephalic salivary or labial cephalic glands. The degree of development of these glands in newly emerged, nurse and forager workers and virgin and egg-laying queens of Apis mellifera Linnaeus, 1758 and Scaptotrigona postica Latreille, 1807 were evaluated by measuring the secretory alveolar units. The area of the secretory alveoli, measured in total gland preparations, was used to evaluate differences in size. In both species, gland size was found to increase progressively from newly emerged workers to foragers and from virgin to egg-laying queens. A... |

| Dado que el picudo del chile es el principal problema fitosanitario en el cultivo de Capsicum spp., y las medidas de control no han logrado mitigar de forma eficiente las poblaciones de este insecto, se estudiaron los siguientes objetivos con el fin de conocer las interacciones planta insecto. Primero se valido un método de recolecta de volátiles, el cual demostró ser eficiente bajo las diferentes variables analíticas estudiadas, con % de recobro de 90-100 y DER menores a 10%. En segundo lugar se evaluó el potencial atrayente de estructuras de la planta como flores, yemas, frutos en desarrollo y frutos comerciales, encontrando que machos prefieren en primer lugar flores y después yemas, y las hembras en su primera opción eligieron yemas y después flores.... |

| Potato tuber moth (PTM), Phthorimaea operculella (Zeller), is one of the pests that cause the most damage to potatoes (Solanum tuberosum L.) in both field crops and storage, especially in regions where summers are hot and dry. Larvae develop in the foliage and tubers of potatoes and cause direct losses of edible product. The use of synthetic pheromones that interfere with insect mating for pest control has been widely demonstrated in numerous Lepidoptera and other insect species. An experiment was carried out during the 2004-2005 season in Valle del Elqui, Coquimbo Region, Chile, to evaluate the effectiveness of different pheromone trap densities to capture P. operculella males for future development of a mass trapping technique, and a subsequent decrease... |

| Potato tuber moth (PTM), Phthorimaea operculella (Zeller), widely world distributed, is one of the most serious insect pest attacking potatoes (Solanum tuberosum L.). Larvae develop in foliage and tubers of potato causing direct losses of edible product. Chemicals treatment to control this pest have shown limited efficacy, especially when larvae is under the soil. The utilization of synthetic pheromones as a tool that interferes with insects mating had been widely demonstrated in numerous moth and others insects species. With the objective to evaluate the efficacy of different doses of pheromone per trap in PTM males captures for its future utilization as a mass trapping technique, two experiments in a complete randomized blocks design, were carried out at... |

| In several insects, sex-pheromones are essential for reproduction and reproductive isolation. Pheromones generally elicit stereotyped behaviors. In moths, these are attraction to conspecific sex-pheromone sources and deterrence for heterospecific sex-pheromone. Contrasting with these innate behaviors, some results in social insects point toward effects of non-sex-pheromones on perception and learning. We report the effects of sex-pheromone pre-exposure on gustatory perception and habituation (a non-associative learning) in male Agrotis ipsilon moths, a non-social insect. We also studied the effect of Z5-decenyl acetate (Z5), a compound of the sex-pheromone of the related species Agrotis segetum. We hypothesized that conspecific sex-pheromone and Z5 would... |

| Callisphyris apicicornis is a fruit pest of increasing concern in Chile. To aid in the identification of its sex pheromone for use in the management of this insect, "calling" (pheromone release) of females and "orientation and searching" behaviors of males to calling females were video recorded. Light intensity, wind speed, temperature, time of the day, and the frequency of individuals performing each step within both behavioral sequences were recorded as well. Drawings of the behavioral steps and ethograms (routes and returns) are also provided, including transition frequencies between behavioral steps. The calling behavior of females included diagnostic movements of the abdomen, legs, elytra, and wings, showing similarities to the descriptions of other... |

| The oriental fruit moth, Grapholita molesta Busck, and fruit flies, Anastrepha fraterculus L., are the important apple pests under Subtropical climate in Southern Brazil, and control is normally accomplished with insecticides. An alternative strategy for the control of G. molesta is mating disruption, through the use of pheromones. Mating disruption strategies using a low density of dispensers (20) per hectare were tested in comparison with conventional pesticides for control of G. molesta in commercial Gala apple orchards in Fraiburgo, SC, for a period of five years. The average field efficiency period of mating disruption formulation over five years was 113 days. In this period the mating interruption index on mating disruption plots was 84.8% over five... |

| Morphological, chemical and developmental aspects of the Dufour gland in some eusocial bees (Hymenoptera, Apidae): a review. The present revision focused on the more recent data about the Dufour gland in some eusocial bees, taking in account general aspects of its morphology, secretion chemical nature, bio-synthetic pathway and development. Many functions have been attributed to this gland in eusocial bees, but none are convincing. With the new data about this gland, not only the secretion chemical pathway of the Dufour gland may be reasonable understood, as its function in some eusocial bees, especially Apis mellifera Linné, 1758, which has been extensively studied in the last years. |

| In recent years the growing concern about environmental changes and how we are using the natural resources have triggered a search for natural products as alternatives to synthetic pesticides. The stink bugs produce a wide variety of chemical compounds (semiochemicals) that show potential to manage these insects. The stink bugs Chinavia impicticornis (Stål), C. ubica (Rolston), Dichelops melacanthus (Dallas), Euschistus heros (F.), Piezodorus guildinii (Westwood), Thyanta perditor (Westwood) and Tibraca limbativentris (Stål) had their blends of defensive compounds evaluated both qualitative and quantitatively. The main compounds identified on the glands of Brazilian stink bugs are: 2-alkenals, mainly the E isomer; saturated aliphatic hydrocarbons; and 4... |

| We previously reported that male mice are more attracted to volatile odors from intact female mice than from ovarlectornized female mice. In the present study, we investigated male attraction to volatile odors from soiled bedding collected from the cages of estrous or ovariectomized female mice. There was no difference in the total time spent sniffing volatile odors from estrous and ovariectomized female mice, suggesting that female mice emit volatile odors which are not excreted into bedding. To test this possibility, we investigated c-Fos expression in the mitral cell layer and granule cell layer of the accessory olfactory bulb 60 min after exposure of male mice to volatile odors without physical contact. Volatile odors from an estrous female mouse... |
