“…The SP was the second most abundant sensilla, being almost twice as abundant in males as compared to females, similar to that reported for other eusocial bees (Stort & Moraes‐Alves, ; Ravaiano et al , ) and bees of the tribe Emphorini (Galvani et al , ). These sensilla are described as being olfactory in some Hymenoptera (Ochieng et al , ; Al Ghamdi, ; Spaethe et al , ).…”

“…Within the same species, differences in terms of types and distribution of sensilla also may be related to caste and sex or different tasks individuals perform in the colony (Sheridan, Iversen & Itagaki, ; Mysore, Shyamala & Rodrigues, ; Ravaiano et al , ; Wittwer & Elgar, ). For instance, males of A. mellifera have a higher number of placodea sensilla than workers, allowing them to locate the queen (Esslen & Kaissling, ; Stort & Moraes‐Alves, ). More recently, studies found differences in the type and number of sensilla among castes and sexes of several species of stingless bees, including the genus Melipona (Nascimento et al , ; Ravaiano et al , ; Campos, ; Carvalho et al , ) .…”

The antennae of the insects have cuticular structures called sensilla that play a pivotal role in the perception of stimuli and in communication. The morphology of antennal sensilla has been characterized in eusocial bees; however, there is little information on bees of the genus Tetragonisca. Using scanning electron microscopy, 11 types of antennal sensilla were identified in Tetragonisca fiebrigi: trichodea (ST, subtypes I-VI), placodea, basiconica, coeloconica, ampullacea, and campaniformia. The largest diversity of sensilla was observed in females. The STI was the most abundant, followed by the placodea and the STII. The STI and the sensila placodea were more abundant in males than females, while the STII were more abundant in workers. Significant differences were found in the length of the different types of sensilla among the classes of individuals, with these differences being greater for the STI in males and the STV in queen; for the STII, STIII, and STIV in queen and workers; and for sensila placodea in queens, workers, and soldiers. Multivariate analysis (PCA and UPGMA) showed that the soldier subcaste was separated from the other females. This study advanced our understanding of sensilla morphology, including the number and distribution of sensilla across sexes and castes, and the sensory structures of T. fiebrigi. The results presented provide relevant information for elucidating the communication mechanisms of social insects.

“…The morphology and abundance of antennal sensilla may vary depending on the insect family (Hashimoto, 1991), subspecies (Stort and Moraes-Alves, 1999), caste (Nakanishi et al, 2009), and developmental stage (Silva et al, 2010). The types and size of sensilla may also vary depend upon the geographical distribution of insects.…”

The ant Atta robusta is endemic to the "restinga" ecosystems where it has an important role in the dynamics of seed dispersal. Despite its importance, A. robusta is considered a threatened species. In this study we analyzed the antennal sensory organs of two different populations of A. robusta (from the cities of São Mateus and Maricá in in Espírito Santo and Rio de Janeiro States, respectively) using a scanning electron microscope (SEM). SEM revealed different types of sensilla in the A. robusta antennae, i.e., curved and straight trichoid, basiconic, ampullacea and coeloconic, which were highly abundant found in the distal flagellomeres (F) compared with other antenna regions. There were differences in samples collected from two locations in terms of the sensilla number and length. The average numbers of straight and curved trichoid sensillae numbers were different in F9 and F8, respectively, while the average length of the curved trichoid sensilla was only different in F9. These variations in sensory organs between two populations of A. robusta may indicate an adaptation of this species to different environmental conditions. The number of straight trichoid sensilla was only significantly different in F9.Keywords: Attini, scanning electron microscopy, sensory organs.Estudo morfológico e morfométrico das sensilas antenais de Atta robusta (Borgmeier 1939) (Hymenoptera: Formicidae) ResumoAtta robusta é uma espécie de formiga endêmica, com papel importante na dinâmica dos ecossistemas de restinga. Apesar de sua importância como dispersora de sementes nesse tipo de ecossistema, essa espécie encontra-se ameçada de extinção. O presente trabalho lançou mão da microscopia eletrônica de varredura (MEV) para descrever as sensilas antenais de A. robusta e investigar diferenças entre sensilas antenais dessa espécie em indivíduos coletados em localidades diferentes, nos municípios de São Mateus (Estado do Espírito Santo) e Maricá (Estado do Rio de Janeiro). Diferentes tipos de sensilas como tricoideas retas e curvadas, basicônicas, ampuláceas e celocônicas foram encontradas nas antenas, sendo que todas são mais numerosas no flagelomero nove (F9) ou mais distal. Houve diferença em número e em comprimento das sensilas tricoideas retas e curvatas em F8 e F9 entre os indivíduos das duas localidades. Os números médios das sensilas tricoides retas e curvadas foram diferentes para os F9 e F8, respectivamente, enquanto que o comprimento médio das sensilas tricoides curvadas foi diferente para o F9. Essa variação na quantidade de sensilas antenais entre as populações é, possivelmente, uma plasticidade fenotípica, característica importante para a adaptação de espécies a variações ambientais. Esse trabalho representa um estudo preliminar na tentativa de se estudar a variação nos órgãos sensoriais entre diferentes populações de A. robusta.Palavras-chave: Attini, microscopia eletrônica de varredura, órgão sensorial.

“…Although several studies about the different types of antennal sensilla in bees (Dietz and Humphreys, 1971;Moraes and Cruz-Landim, 1972;Stort and Moraes-Alves, 1999;Al-Ghamdi, 2006), histological analysis of the development of these sensilla in stingless bees was performed only in Melipona quadrifasciata anthidioides (Azevedo et al, 2008). Therefore, the analysis of the development of the antennal sensilla in other species of bees is important to confirm previous data and find new information that contributes to the understanding of these sensory organs.…”

The antennal sensilla are sensory organs formed by a group of neurons and accessory cells, which allow perception of environmental cues, which play a role as mechanoreceptors and chemoreceptors. This study describes the post-embryonic development of the antennal sensilla of the stingless Tetragonisca angustula (Hymenoptera: Meliponini) workers. The development of the antennal sensilla begins in the transition stage of the pre-pupae to white-eyed pupae. The sensilla are completely developed at the black-eyed pupae stage, but they are covered by the old cuticle. The sensilla are exposed to the environment only in newly emerged workers of T. angustula, but it is possible that environmental stimuli can be recognized due to the pores in the old cuticle.Keywords: placoid sensilla, trichodea sensilla, stingless bee, pupal development.Desenvolvimento das sensilas antenais de Tetragonisca angustula latreille, 1811 (Hymenoptera: Meliponini) durante a pupação ResumoAs sensilas antenais são órgãos sensoriais formados por um conjunto de neurônios que captam estímulos ambientais e células acessórias, desempenhando as funções de mecanorreceptores e quimiorrecepterores. Este trabalho descreve o desenvolvimento pós-embrionário das sensilas antenais de operárias das abelhas sem ferrão Tetragonisca angustula (Hymenoptera: Meliponini). O desenvolvimento das sensilas tem início na transição de pré-pupa para pupa de olho branco e estão completamente desenvolvidas no estágio de pupa de olho preto, mas ainda estão cobertas pela cutícula velha. As sensilas estão completamente expostas em operárias recém-emergidas de T. angustula, mas é possível que estímulos ambientais sejam percebidos em estágios anteriores devido aos poros presentes na cutícula velha.Palavras-chave: sensila placoide, sensila tricoide, abelha sem ferrão, desenvolvimento pupal.

“…For instance, male Apis mellifera exhibit more sensilla placodea than workers. These sensilla are believed to help males to encounter females during nuptial flights because increased numbers of sensilla placodea enhance the olfactory acuity of the males (Stort and Moraes-Alves 1999).…”

The antennal forms and sensilla of queen and workers honeybees Apis mellifera L. (Hymenoptera: Apidae) were examined using scanning electron microscopy (SEM) to describe the types, and distribution of sensory structures to ascertain the relationship between sensory structures and behavior. Differences were found in sensilla types' diversity and distribution on the antennae of queens grafted from 12 and 48 hrs and workers honey bees. The scape with long trichoid were found in workers but with special very long in size for the queens honey bee. The pedicle with trichoid (short and long) were found in both worker and queen honeybee. There is a significant association between type, size and density of sensilla on flagellum segments. The segments of flagellum from 3 rd to 10 th are bearing placoid different in shape and size (oval, circle and square) and different in number on queen and worker. Basiconicum (large and small) with apical one pore were present with strong hook (curved shape) on second segment of flagellum in the worker but absent in the queen honey bees. The sensilla amplluicica and coeloconica were found on the same flagellum segments. There is a great variety of sense organs on the apical segment of flagellum for both workers and queen honeybees. The numbers of sensilla trichoid, placodea, campaniform, Basiconicum, amplluicica, and coeloconica varied most among bee casts and also antennal segments (scape, pedical and flagella).
