| 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.... |

| The number of sensilla campaniformia and sensilla coeloconica + sensilla ampullacea of flagellomeres 2 to 11 of the antennae of three types of males (Italian, African and Africanized) was determined by scanning electron microscopy. Comparison of the three male types showed that Italian males did not differ from African males in number of sensilla coeloconica + sensilla ampullacea and that both differed from Africanized males in terms of flagellomere 11. With respect to flagellomeres 3 and 10, Italian males were similar to Africanized males and both differed from African males. No differences between the three male types were detected in the other flagellomeres. In relation to the number of sensilla campaniformia Italian males differed of the African and... |

| 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 prey, non-rotten prey and a control). Using dead crickets in a box covered with a mesh, and recording the time the harvestmen spent in the vicinities of the box, we show that D. pectinifemur detects non-rotten prey and stays longer on it than on the other two treatments. Our results contrast with a previous study on another species, showing that we should not generalize results obtained for one species.... |

| ABSTRACT The larva of the whirligig beetle Enhydrus sulcatus (Wiedemann, 1821) is described and illustrated for the first time, including detailed morphometric and chaetotaxic analyses of the cephalic capsule, head appendages and legs. Larvae of Enhydrus Laporte, 1834 exhibit the characters traditionally recognized as autapomorphies of the family Gyrinidae: well developed cardo, completely divided prementum, presence of lateral abdominal tracheal gills, and presence of four terminal hooks on the pygopod. The egg bursters located on the parietal, the presence of an additional sensorial plate on the third antennomere, and a well developed lacinia may also represent autapomorphies of the family. Enhydrus larvae share with those of the other known Dineutini... |

| The external morphology of the sensilla, including pores and permeable points on the cuticle of the antennae of adults of Neomegalotomus parvus (West.) (Heteroptera: Alydidae) was investigated with regard to their olfactory function. Behavioural evidence of olfaction, the importance of the different antennal segments in locating the host under still-air, and the responses of the insects to plants' scents and to pheromones in wind assays were also studied. With the scanning electronic microscope mechanoreceptor sensilla were found on the four segments of the antennae of N. parvus. The density of the sensilla was greater on the 4th segment. On the apical segment, sensilla with olfactory morphological traits were observed. Bugs with intact antennae located... |

| The mouthparts of Synempora andesae Davis & Nielsen were studied by means of scanning electron microscope. The existence of gustative uniporous sensilla styloconica is demonstrated for the second time on the proboscis of Neopseustidae. It is with this family, and not at a later stage within the Incurvaroidea, that these sensilla appear during the evolution of Lepidoptera. Contrary to common belief, the labial-palp-pit organ, or organ of vom Rath, is present at the distal extremity of the labial palpi of S. andesae. It is made up of a dozen of grooved multiporous sensilla coeloconica whose function is carbon dioxide sensitive. Thus, its presumed absence can no longer be considered as an autapomorphy of Neopseustidae. S. andesae possesses other... |

| The external morphology of sensilla on the antennae of males and females of Phyllophaga ravida Blanchard is described using scanning electron microscopy. Sexual dimorphism in body and antennal dimensions and in antennal receptor types was found. The female's body is slightly larger than the male's, although male antennal lamellae are longer than in females. Sixteen types of sensilla were identified on the proximal and distal surfaces of lamellae from both sexes, most of them in males: three types of placodea sensilla, four types of auricilica sensilla, five types of basiconica sensilla, and four types of coeloconica sensilla. Also, two types of mechanoreceptor sensilla were present on the lamellae periphery. Furthermore, males had larger placodea,... |
