Leaf-cutting ants belonging to the genus Atta (Formicidae: Myrmicinae) are important pests in agricultural and forest environments. In the present study, we evaluated the formicidal activity of the essential oil of Pogostemon cablin and its nanoformulation on the leaf-cutting ants: Atta opaciceps (Borgmeier, 1939), Atta sexdens (Linnaeus, 1758), and Atta sexdens rubropilosa Forel, 1908. The nanoformulation was developed by magnetic stirring using polyoxyethylene (36%), pure ethanol (36%), essential oil of P...

Symbiosis between plants and ants include examples in which the plant provides shelter and/or food for ants that, in turn, act in the defense or in the dispersion of seeds from the host plant. Although traditionally referred as mutualistic, the results of these interactions may vary with the ecological context in which patterns are involved. A range of species have facultative association with Turnera subulata (Turneraceae). Here, using behavioral bioassays, we investigated the effects of the most frequent ant species associated with T...

Rhinoleucophenga Hendel comprises an unusual Drosophilidae (Diptera) genus with predaceous larvae, currently compounded by 29 nominal species with New World distribution. In the present study, Rhinoleucophenga brasiliensis (Costa Lima) and R. fluminensis (Costa Lima) are redescribed. These two species are commonly misidentified in Drosophilidae species inventories, mainly by the few morphological character details presented in the original taxonomic description. Thus, by the morphological review performed here, lectotype and paralectotypes designed to R...

Samples of corbicular and stored pollen gathered by Tetragonisca angustula (Latreille, 1811) in an Amazon-Chiquitano transitional forest during the dry season were analyzed. The pollen spectrum was established as well as the dynamics of the relationship between the stingless bee and the surrounding flora. Pollen samples obtained from three rational hives were subjected to acetolysis and 55 pollen types were identified, the most frequent being from Anadenanthera (Fabaceae), Chenopodiaceae, and Dydimopanax (Araliaceae)...

Thaumastocoris peregrinus Carpintero & Dellapé (Hemiptera: Thaumastocoridae) is a small sap-sucking insect that feeds on Eucalyptus L'Hér. leaves. Although it is native to Australia, it currently has a global distribution and it is considered as one of the big five pests of eucalypts around the world. We described the development of T. peregrinus population on four Eucalyptus species under the environmental conditions in Argentina. We also analyzed the use of yellow sticky traps as a monitoring method for this pest...

Pitfall traps are commonly used for the collection of terrestrial insects in ecology and biology studies; they are relatively straightforward to manufacture and there is a large variety of models described in the literature. However, they present a few drawbacks: (i) the removal and transport of the collected material are not practical; (ii) they have low resistance and durability; (iii) they fail to correctly protect the attractive bait against adverse weather conditions and scavengers, and (iv) evaporation of the liquid used inside the trap...

Feltia submontana (Köhler, 1961) is redescribed based on specimens from Northwestern Argentina and Central and Southeastern Brazil. Taxonomic comments, photographs of the adults, characters of taxonomic importance, and illustrations of structures of the labial palpus, legs, and male and female genitalia are provided. The species is compared with similar-looking and supposedly closely related species, such as F. hispidula (Guenée, 1852) and F. lilacina (Zerny, 1916). The species, originally described for Argentina, is reported for Brazil for the first time...

The taxonomic limits of the Neotropical genus Dotocryptus Brèthes are reviewed. The genus is characterized mainly by the very long ovipositor, at least 2.2× as long as hind tibia; apex of ovipositor distinctly depressed, ventral valve expanded, and overlapping dorsal valve as a sheath; and mandible long with ventral tooth longer than dorsal one. A new species, Dotocryptus arcadius sp. nov., from Colombia is described and illustrated. The new species can be diagnosed mainly by the head and mesosoma with multiple whitish marks; epicnemial carina reaching 0...

Chaetosiphon fragaefolii (Cockerell) (Hemiptera: Aphididae) is the predominant aphid in strawberry (Fragaria × ananassa Duchesne) production systems in Brazil. This pest species directly damages the plants and is also responsible for spreading viruses. Further, C. fragaefolii often renders strawberry cultivation unviable, because of its high reproductive rate, as well as the large number of individuals generated through parthenogenesis. The present study aimed to (1) evaluate the feeding behavior of C. fragaefolii in four strawberry cultivars (Albion, Aromas, Camarosa, and San Andreas) and (2) identify the resistance factors associated with the number and type of trichomes in the cultivars, and also its effect on the feeding behavior of C...

Culex (Microculex) daumastocampa Dyar & Knab was originally described by Dyar and Knab (Proc US Nat Mus 35:53-70, 1908) from larvae collected at axils of bromeliads in Port San Felipe, Panama. Culex daumastocampa is found in Colombia, Venezuela, Panama, Suriname, Costa Rica, Nicaragua, Guatemala, and Mexico, although its presence had not been reported suggesting its northernmost distribution. In Mexico, the subgenus Microculex had included Cx. rejector Dyar and Knab, and Cx. imitator Theobald. However, after that collection specimens were re-examined along with other specimens collected during 2016 in Chiapas (all specimens are available in the Culicidae Collection of the Universidad Autonoma Agraria Antonio Narro Unidad Laguna [UAAAN-UL], Mexico)...

The cotton bollworm Helicoverpa armigera (Hübner) is a widespread lepidopteran pest found in various crops worldwide. This highly polyphagous species, commonly found both in the Old and New World, has caused significant economic damage as an invasive agricultural pest in Brazil since 2013. The goal of the present study is to provide a detailed morphological assessment of adults and immature stages of H. armigera, as this species is often confused with H. zea (Boddie), a congeneric species that is native to the New World...

Bemisia tabaci (Genn.) biotype B (Hemiptera: Aleyrodidae) is an important pest of vegetable crops, including collard greens Brassica oleracea var. acephala (Brassicaceae). The use of resistant genotypes is an interesting option to reduce insect populations and can be used as an important tool for integrated pest management (IPM). This study evaluated 32 genotypes of collard greens against the attack of silver leaf whitefly, with the aim to characterize antixenosis. Initially, a multiple-choice trial was conducted using all genotypes, in which the adult attractiveness was assessed on two leaves per genotype at 24 and 48 h after infestation...

A second species of the genus Pararrhopalites is described from caves inserted in iron ore lithology. Both species present a particular sensory organ in the interantennal region. The new species, Pararrhopalites ubiquum n.sp., has a wider distribution and it is not restricted to a single cave, as it is the case of Pararrhopalites sideroicus Zeppelini & Brito, in Fla Entomol 97(4):1733-1744, 2014, being found even in the Mesovoid Shallow Substratum. An update to the previously published identification key is presented...

Inundative biological control depends on the ability of natural enemies to disperse and persist in the environment. The objective was to evaluate the dispersion and persistence of Trichogrammatoidea bactrae (Nagaraja) on Tuta absoluta (Meyrick) eggs. Inundative releases of this parasitoid were performed in experimental tomato greenhouses. For vertical dispersion, leaves of the upper and middle third of plants were artificially infested with T. absoluta eggs; for horizontal dispersion, plants at increasing distances from a release point were infested...

Three endemic Caribbean praying mantis genera with a complex taxonomic history were recently discovered to be part of a lineage that colonized the Caribbean region during the Cretaceous period (Svenson & Rodrigues, Proc R Soc B Biol Sci 284, 2017). In all classification systems proposed up to now, the three genera, Callimantis, Epaphrodita, and Gonatista, were never considered as close relatives, a reflection of their divergent morphology. More recently, the genus Brancsikia was placed with Epaphrodita in a family based on the similarity of camouflage-related morphology...

Successful biological control requires detailed knowledge about host preferences of the released parasitoid, because the presence of alternative hosts may affect the control of the target pest. The objective of this work was therefore to evaluate host preferences of Telenomus podisi Ashmead among the eggs of three stink bug species: Dichelops melacanthus Dallas, Euschistus heros Fabricius, and Podisus nigrispinus Dallas (Heteroptera: Pentatomidae). Three independent experiments were carried out to study host preferences among the following: (1) E...
