The sensilla of insects play important roles in odor, taste, the feeling environment, and some sensory functions, which are closely associated with insect host locating, feeding, habitat searching, courtship, mating, and oviposition. In this study, we used a scanning electron microscope to observe the external morphology of nymph and adult Frankliniella occidentalis sensilla on antennae, compound eyes, legs, mouthparts, wings and tail. The results show that three main types of sensilla are located on the antennae: sensilla trichodea, sensilla chaetica, and sensilla basiconica. Among them, sensilla trichodea are the most abundant, followed by sensilla chaetica. Sensilla basiconica on antennae are divided into seven sub-styles, including longer sensilla (L-sensilla basiconica, long sensilla basiconica), shorter sensilla (angle sensilla basiconica, bud sensilla basiconica), and thicker and bigger sensilla (stick sensilla basiconica, fork sensilla basiconica, and finger sensilla basiconica). Only two fork sensilla basiconica were found, located on the dorsal part of the first flagellum subsegment and the ventral part of the second flagellum subsegment, respectively. Seven sensillum types were found on the legs: sensilla trichodea, sensilla chaetica, sensilla basiconica, sensilla ear washing buob-shaped, mamillary sensilla, sensilla campaniform, and Böhm bristle. About 60% of them are sensilla chaetica. Only one sensillum type was found on compound eyes: sensilla chaetica. In addition, some sensillum types were also found on the mouthparts, wings and tail, respectively. In the study, we observed the type, morphology, and distribution of sensilla on antennae, legs, compound eyes, and other regions of nymph and adult F. occidentalis, forming a base for future electrophysiological and behavior experiments on F. occidentalis.

Ficus inflorescences host a species-rich chalcid wasp community, including pollinating fig wasps (Agaonidae: Tetrapusinae, Kradibiinae, and Agaoninae) and several species of non-pollinating fig wasps (NPFW), that show several life-history strategies, including gall-inducers, kleptoparasites (i. e. inquilines), and parasitoids. We analyzed the structure and degree of specialization of the fig wasp community associated with Ficus inflorescences in urbanized areas, agroecosystems, and on the edge of forest fragments in the state of Goiás (Brazil). We sampled 34 wasp species in four native Ficus tree species, from which four wasp species occurred in more than one host. Neotropical fig pollinators (Pegoscapus and Tetrapus) were the most abundant species, and they were host-specific, although two pollinator species were associated with Ficus obtusifolia. The Jaccard similarity index was higher in samples of fig wasps collected in the same host, indicating that the community composition was specific to each host species. Community structure indices indicate a specialized structure with low connectance, high bidimensional Shannon H2’ and low partner diversity. The communities present a modular web structure in which modules were represented by each host and its associated insect species. These results indicate that the fig wasp communities analyzed are highly specialized, despite a few not strictly host-specific species.

榕树花序上寄生着一个种类丰富的酸蜂群落，包括授粉榕蜂(Agaonidae: Tetrapusinae, Kradibiinae和Agaoninae)和几种非授粉榕蜂(NPFW)，它们表现出几种生活史策略，包括胆管诱导剂，盗寄生(即inquilines)和拟寄生物。我们分析了巴西Goiás州城市化地区、农业生态系统和森林碎片边缘与榕属花序相关的榕黄蜂群落的结构和专业化程度。我们在4种本地榕属树种中采集了34种寄生蜂，其中4种寄生蜂出现在一个以上的寄主中。新热带无花果传粉媒介Pegoscapus和Tetrapus是最丰富的物种，它们是宿主特异性的，尽管有两种传粉媒介与无花果有关。同一寄主采集的榕小蜂的Jaccard相似性指数较高，表明群落组成对不同寄主具有特异性。群落结构指标表现为低连通性、高二维Shannon H2′和低伴侣多样性的特化结构。群落呈模块化的网状结构，其中每个单元由每个寄主及其伴生昆虫种代表。这些结果表明，所分析的无花果黄蜂群落是高度专门化的，尽管有一些不是严格的宿主特异性物种。A R T I C L E I N F O文章历史:2021年9月28日收稿2022年1月25日接收在线2022年3月25日副主编:Marcelo Tavares

15 known species distributed worldwide, including three species in the neotropics. The species of Calythea can be easily identified by having bright silvery grey-dusting on the thorax and abdomen, forming a contrasting pattern with the dark body. Herein, we describe two new species from the Neotropical region and present new records of the genus for Argentina, Brazil, Chile, Colombia, Ecuador and Peru. We also redescribe Calythea comis (Stein). In addition, we present an identification key for the Neotropical species and drawings of the terminalia and habitus images of the new species, C. comis, C. crenata (Bigot) and C.
