Memórias do Instituto Oswaldo Cruz , 1989, DOI: 10.1590/S0074-02761989000400002
Abstract: we studied by sanning electron microscopy the number, types, structure and distribution of the antennal sensilla of the medical important ceratopogonid culicoides paraensis (goeldi). there are about 174 sense organs on the antenmal flagellum which are classified as sensilla chaetica; sharp-tipped and blunt-tipped (type i and ii) sensilla trichodea; sensilla basiconica; sensilla coeloconica; sensilla ampullacea and styloconic-type sensilla. the role of antennal sensory organs are discussed regarding the host preference of the biting midges.

Abstract: in order to determine if habitat similarity is correlated with a similarity of sensilla pattern, we analyzed six species of triatominae present in two biogeographic regions of brazil: the "caatinga" and the "cerrado". in broad terms triatoma infestans (cerrado) and t. brasiliensis (caatinga) are found in human domiciles, t. sordida (cerrado) and t. pseudomaculata (caatinga) colonize peridomestic habitats, and rhodnius neglectus (cerrado) and r. nasutus (caatinga) inhabit palm tree crowns. the number and distribution of four sensilla types (bristles, thin and thick walled trichoidea, and basiconica) were compared in these species. sexual dimorphism of sensilla patterns was noted in t. sordida, t. brasiliensis and t. pseudomaculata. a principal component analysis showed three main groups: (i) species that live in the palms, (ii) domiciliated species and (iii) those living in the peridomestic habitat. t. infestans almost exclusively domestic, was placed at the centre of the canonical map and some individuals of other species overlapped there. these results support the idea that the patterns of antennal sensilla are sensitive indicators of adaptive process in triatominae. we propose that those species that inhabit less stable habitats possess more types of sensilla on the pedicel, and higher number of antennal sensilla.

Abstract: with the aid of scanning electron microscopy, the external morphology and distribution of the antennal sensilla were described for females of gryon gallardoi (bréthes), an egg-parasitoid of coreids. the geniculated and clavated antennae are composed of 12 antennomeres. along the flagelum we registered dorsal glands and seven types of sensilla: papillary, chaetica of two sizes - long and short types, styloconic grooved-peg, sickle-shaped and trichodea with numerical and spatial variation among the flagellomeres. functional aspects of the sensilla are discussed in the context of g. gallardoi antennal drumming behavior. thus, the determination and the description pattern of antennal sensilla in g. gallardoi, in the present study, is an advance regarding the elucidation of the mechanisms involved in the host selection behavior of this species.

Abstract: With scanning electron microscope (SEM), this paper observed the shape, category, amount and distribution of the main antenna sensilla of adult Monochamus alternatus, and tested their electroantennographic (EAG) responses to the main volatiles of Pinus spp.. There were seven types of antennal sensilla, i. e., sensilla trichoid, sensilla basiconica, sensilla digit-like, sensilla rod-like, sensilla bottle-like, sensilla bud-like and sensilla chaetica, among which, sensilla trichoid and sensilla basiconica were the most abundant on the antenna surface, and each of them could be divided into three subtypes. Two subtypes of sensilla digit-like could also be observed. The II and III subtypes of sensilla trichoid and I and II subtypes of sensilla basiconica had deep longitudinal grooves on their surface, the typical characteristics of olfactory receptor. The comparison of the EAG response of different parts of Monochamus alternatus antennae to alpha-Pinene showed that each volatile and their compounds could provoke significant EAG responses of both females and males. The dose-response test showed that there was a certain rule in the EAG responses of M. alternatus.

Abstract: we examined changes in the array of antennal sensilla of three species of triatominae (triatoma infestans, rhodnius prolixus, and r. pallescens) following their establishment for different periods in laboratory culture. in each case, the laboratory colonies were compared with conspecific samples taken directly from the field, by quantitative analysis of the sensilla arrays on the three distal segments of the antenna in terms of the densities of three types of chemoreceptors (basiconics and thick and thin walled trichoids) and one type of mechanoreceptor (bristles). sensilla densities were compared by anova or non-parametric tests, and by multivariate discriminant analysis. strains of the same species reared in different laboratories showed significant differences in their sensilla arrays, especially when compared to field-collected material from the same geographic origin. a bolivian strain of t. infestans reared in the laboratory for 15 years and fed at monthly intervals, showed greatest differences from its conspecific wild forms, especially in terms of reductions in the number of chemoreceptors. by contrast, an argentine strain of t. infestans reared for 25 years in the laboratory and fed weekly, showed a relative increase in the density of mechanoreceptors. a colombian strain of r. prolixus reared for 20 years and fed weekly or fortnightly, showed only modest differences in the sensilla array when compared to its wild populations from the same area. however, a colombian strain of r. pallescens reared for 12 years and fed fortnightly, did show highly significant reductions in one form of chemoreceptor compared to its conspecific wild populations. for all populations, multivariate analysis clearly discriminated between laboratory and field collected specimens, suggesting that artificial rearing can lead to modifications in the sensory array. this not only supports the idea of morphological plasticity in these species, but also suggests caution in the use of long-e

Abstract: We examined changes in the array of antennal sensilla of three species of Triatominae (Triatoma infestans, Rhodnius prolixus, and R. pallescens) following their establishment for different periods in laboratory culture. In each case, the laboratory colonies were compared with conspecific samples taken directly from the field, by quantitative analysis of the sensilla arrays on the three distal segments of the antenna in terms of the densities of three types of chemoreceptors (basiconics and thick and thin walled trichoids) and one type of mechanoreceptor (bristles). Sensilla densities were compared by ANOVA or non-parametric tests, and by multivariate discriminant analysis. Strains of the same species reared in different laboratories showed significant differences in their sensilla arrays, especially when compared to field-collected material from the same geographic origin. A Bolivian strain of T. infestans reared in the laboratory for 15 years and fed at monthly intervals, showed greatest differences from its conspecific wild forms, especially in terms of reductions in the number of chemoreceptors. By contrast, an Argentine strain of T. infestans reared for 25 years in the laboratory and fed weekly, showed a relative increase in the density of mechanoreceptors. A Colombian strain of R. prolixus reared for 20 years and fed weekly or fortnightly, showed only modest differences in the sensilla array when compared to its wild populations from the same area. However, a Colombian strain of R. pallescens reared for 12 years and fed fortnightly, did show highly significant reductions in one form of chemoreceptor compared to its conspecific wild populations. For all populations, multivariate analysis clearly discriminated between laboratory and field collected specimens, suggesting that artificial rearing can lead to modifications in the sensory array. This not only supports the idea of morphological plasticity in these species, but also suggests caution in the use of long-established laboratory material for experimental studies designed to extrapolate the natural behaviour and physiology of these species.

Abstract: 中文摘要:利用扫描电子显微镜,研究了卡氏步甲 Carabus casaleianus成虫触角感器的类型、数量和分布规律。结果表明:卡氏步甲雌、雄成虫触角的各节长度和总长度差异均不显著;触角表面存在7类、12种感器类型,包括3种刺形感器、3种毛形感器、2种锥形感器、B?hm氏鬃毛、腔锥形感器、腔形感器和钟形感器;两性间触角感器的类型和分布无明显差异,但数量差异明显。研究结果为其后的电生理学、行为生态学等研究提供基础资料。
英文摘要:The typology, number, and distribution pattern of the antennal sensilla of Carabus casaleianus were studied using scanning electron microscopy. The results showed that there was no significant difference of the length of each segment and the total length of the antennal between male and female C. casaleianus. The antennal had seven types of sensilla, including three sensilla chaetica, three sensilla trichodea, two sensilla basiconica, one sensilla coeloconica, one sensilla cavity, one sensilla campaniformia and one B?hm bristles. These results suggested that there was no remarkable difference in the types and distribution of antennal sensilla in both genders, even though the numbers were significantly different. This work provided basic data for future electrophysiological and behavioural experiments. 2015,34(6): 896-902 收稿日期:2015-03-09 DOI:10.11984/j.issn.1000-7083.20150080 分类号:Q969 基金项目:安徽大学青年科学研究基金项目(02303305); 安徽大学2012级研究生学术创新研究项目 作者简介:齐钦,男,硕士研究生,研究方向:昆虫生态学,E-mail:674899245@qq.com *通讯作者:方杰,E-mail:ahufangjie@126.com 参考文献: 陈静, 花保祯. 2014. 山茱萸蛀果蛾幼虫触角和口器感器的超微形态[J]. 昆虫学报, 57(1): 133-140. 李维娜. 2013. 蓟马科昆虫头部感器形态和超微结构研究[D]. 杨凌: 西北农林科技大学. 刘桂清, 田明义. 2008. 奇步甲触角感器电镜扫描观察和触角电位反应[J]. 华南农业大学学报, 29(2): 50-58. 宋月芹, 董钧锋, 孙会忠, 等. 2012. 四种金龟成虫触角的板形感器和腔锥形感器形态对比[J]. 四川动物, 31(6): 905-908. 张毅, 谢映平, 薛皎亮, 等. 2014. 红环瓢虫触角感器的扫描电镜观察[J]. 四川动物, 33(4): 578-583.
