Volume: 6 - Issue: 0

Resumo. Meliponaries are an alternative for the preservation of stingless bee species, in addition to producing raw material for the pharmaceutical and cosmetic industry. The presence of invaders that can cause damage to the integrity of productive areas is something that is frequently reported. The same happens in meliponaries, where bees can have many natural enemies, whether vertebrates or invertebrates. Updating new records and management methods are crucial to avoid major losses in production. The aim of this work is to report the first occurrence of the clown beetles, Hololepta (Leionota) reichii (Marseul, 1853) (Insecta: Coleoptera: Histeridae) in meliponaries of the state of Ceará, Brazil, and provide notes on the methods used to control it. A total of 109 individuals (40 females; 69 males) were collected between February and July 2022, placed in alcohol 70%, and subsequently identified. Measures such as the removal of decaying organic materials from nearby the colonies, added to frequent inspection, internal and external cleaning of the hive boxes after infestations, in addition to the elimination of beetles found in the hives, had a positive effect in reducing the records of attacks.

First record of parasitoidism in Danaus erippus (Cramer, 1775) pupae (Lepidoptera, Nymphalidae): A possible mediation by an exotic plant species - (2024)

Wenrique Verza, Marcelo T. Tavares, Alan Eriksson

Volume: 6 - Issue: 0

Resumo. Monarch butterflies have a close relationship with plants of the Apocynaceae family, especially with the genus Asclepias Linnaeus, 1753, using their toxic cardenolides as a defense against predators. Calotropis procera (Aiton) W.T. Aiton, 1811, native from Africa and Asia and introduced in Brazil as an ornamental plant, is a food alternative for monarchs but contains fewer cardenolides than Asclepias, which may make the butterflies more vulnerable to parasitoids. The interaction between wasps of the genus Brachymeria Westwood, 1829 and butterflies of the genus Danaus Kluk, 1802 is seldom reported. This study reports the first case of parasitism by Brachymeria pandora (Crawford, 1914) in pupae of Danaus erippus (Cramer, 1775) in Brazil, collected in the city of Cuiabá, Mato Grosso. Five butterfly pupae were collected on C. procera; three were parasitized, with 34 emergences of parasitoids. We suggest that the relationship between D. erippus and B. pandora may be facilitated by the lower toxicity of C. procera compared to Asclepias, possibly increasing susceptibility to parasitoidism. The high rate of parasitoidism observed suggests that this possible new interaction could be detrimental to the conservation of D. erippus. Further studies are needed to confirm whether this parasitoid-host interaction also occurs with native Asclepias plants and to investigate the impacts of exotic plants on these types of interactions and on butterfly conservation.

Rodolfo V. Castilhos, Juracy C. Lins Junior, Janaína P. Santos, Lucas R. P. Gomes

Volume: 6 - Issue: 0

Resumo. The root maggot fly, Delia sanctijacobi (Bigot, 1885) (Diptera: Anthomyiidae), is an emerging pest of many vegetables. In this note, we report for the first time the occurrence of D. sanctijacobi damaging the tomato (Solanum lycopersicum L.) culture in Brazil. The occurrence was recorded in a tomato field located in the municipality of Coronel Freitas, Santa Catarina. The damage was characterized by roots consumption, opening of galleries in the stem and plant stand reduction. The first detection of D. sanctijacobi on tomato in Brazil brings an alert to growers and the need of future research about population dynamics and development of management strategies for this species.

First report of Acutaspis oliveirai (Lepage & Giannotti, 1942) (Hemiptera: Diaspididae) in Central Brazil: occurrence on Myrsine guianensis (Aubl.) Kuntze (Primulaceae) in the Brazilian Cerrado - (2024)

Marcelo T. Castro, Sandro C. L. Montalvão, Vera R. S. Wolff

Volume: 6 - Issue: 0

Resumo.  Recent research shows that the Cerrado has a great diversity of scale insects (Insecta: Hemiptera: Coccomorpha) in association with native plants. This work aimed to report the occurrence of Acutaspis oliveirai (Lepage & Giannotti, 1942) (Hemiptera: Diaspididae) found for the first time in Central Brazil and in plants of Myrsine guianensis (Primulaceae), a common species in the Brazilian Cerrado, that has potential for use in landscaping and the recovery of degraded areas. This is the first report of the occurrence of A. oliveirai in a native plant of the Cerrado biome and in the Central Brazil. Acutaspis oliveirai individuals were found on the leaf surface of M. guianensis leaves in two locations in the Federal District, Brazil, causing irregular yellowing and chlorotic spots throughout the leaf blade.

Ground-dwelling ants (Hymenoptera: Formicidae) in a mining area of Quipama, Boyacá, Colombia, with new species records - (2024)

Angelo J. Ávila-Jiménez, Ricardo Martínez-Gamba

Volume: 6 - Issue: 0

Resumo. Mining is a process with great environmental impact that implies important consequences for biodiversity, including its loss. Here, we present a list of 13 species of ants that were collected in a high-impact mining exploitation area of Quipama, Boyacá, Colombia. Notably, the records of Pheidole subarmata Mayr, 1884 and Camponotus ager (Smith, 1858) are new for the department. Although the presence of these species indicates serious disturbance by human activity in the area, there is still a considerable diversity of ants. This study highlights the need for actions to ensure the management and rehabilitation of areas affected by mining.

Lead bioaccumulation in herbivorous insects and parasitoids reared on plants grown in lead-contaminated soil under field conditions - (2024)

Tiago Morales-Silva, Bruna Corrêa-Silva, Lucas D. B. Faria

Volume: 6 - Issue: 0

Resumo. We investigated the lead (Pb) bioaccumulation in herbivorous insects and parasitoids on kale plants (Brassica oleracea var. acephala) cultivated in soils experimentally contaminated. We cultivated kale in soil with lead nitrate concentrations of 0 (control), 144, 360, and 600 mg/Kg of soil, representing permissible levels for Brazilian soils. The plants were kept in an open greenhouse to allow the natural colonization by insects under field conditions. We collected insects through direct removal or trap bags. Dried samples of leaves, herbivorous sap-sucking and chewing insects, and their respective parasitoids were analyzed utilizing ICP-OES to determine Pb concentrations. Pb was transferred in this system, with insects showing higher Pb content than leaves, and the highest values being found in parasitoids, which exhibited the highest levels ever recorded, even though our foliar Pb levels were lower than those in laboratory assays conducted up to then. These results indicate Pb biomagnification. We discuss Pb bioaccumulation effects on herbivores and parasitoids, comparing them with laboratory studies. We provide unprecedented insights into heavy metal bioaccumulation in field herbivorous insects and parasitoids.

Agno N. S. Acioli, Neliton M. Silva, Ricardo Adaime, Francisco C. Costa-Silva, Roberto A. Zucchi

Volume: 6 - Issue: 0

Resumo. Since its detection in Brazil in 1901, the Mediterranean fruit fly, Ceratitis capitata (Wiedemann, 1824) has continuously extended its occurrence in Brazil. The last Brazilian states in the North region of the country without records of the Mediterranean fruit fly were invaded in the current decade - Acre and Roraima in 2017 and Amapá in 2022 - leaving only the state of Amazonas to complete the spread of the Mediterranean fruit fly in all Brazilian states. In the state of Amazonas, the Mediterranean fruit fly was detected in a mango fruit purchased at a commercial establishment. This record is an alert to phytosanitary agents to establish strategies to monitor the occurrence of this pest in the state. We also discuss the first records of C. capitata in each Brazilian state, establishing the chronological order of these records in Brazil from 1901 to 2024.

Volume: 6 - Issue: 0

Resumo. Molecular confirmation of the presence of the tomato leafminer, Phthorimaea (Tuta) absoluta Meyrick, 1917 (Lepidoptera: Gelechiidae), in the Paksong region of the Bolaven Plateau in Champasak province in south-western Lao PDR is reported. The moth, which is native to South America, has invaded many countries in Europe, Africa, and Asia since 2006, and, based on regional records possibly entered Lao PDR between 2014 and 2018. It is a devastating pest of solanaceous crops and threatens tomato production worldwide. Further surveys are required to determine its presence in other regions of Lao PDR and effective management programs must be developed to help farmers minimise losses.

Necrophagy in cave environments: ecological pressure due to food scarcity? A case study of necrophagy by a harvestman Discocyrtanus canjinjim Carvalho & Kury, 2017 (Arachnida: Opiliones) preying on an Eidmanacris sp. (Orthoptera: Phalangopsidae) carcass - (2024)

Vinícius F. Sperandei, Cristina M. Borges, Marcel S. Araújo

Volume: 6 - Issue: 0

Resumo. Cave environments present stable abiotic conditions, including permanent darkness, high humidity, and mild temperatures, while biotic factors reflect simplified ecological networks and energy constraints. Cave invertebrates, primarily detritivores and generalists, demonstrate specific adaptations to these conditions. Predation and necrophagy are critical behaviors shaped by the cave's scarcity of food resources. In this study, we report a rare necrophagy event involving Discocyrtanus canjinjim Carvalho & Kury, 2017 (Arachnida: Opiliones) feeding on a deceased cricket (Eidmanacris sp.) (Orthoptera: Phalangopsidae) in the Ponte de Pedra I Cave, Brazil. This limestone cave features large entrances and supports an oligotrophic system. The event occurred in an aphotic zone, where the harvestman displayed no flee behavior despite external stimuli. The presence of other predatory arachnids suggests potential intra-guild competition. Opiliones in the Cerrado and Caatinga exhibit opportunistic carnivory, consuming various prey taxa, including insects and vertebrates. Necrophagy, intra-guild predation, and cannibalism are behaviors reported in subterranean populations due to limited food availability. Climate change and anthropogenic pressures, such as deforestation and mining, threaten the stability of cave environments. Observations like this contribute to understanding the ecological dynamics within caves, highlighting the importance of preserving these fragile ecosystems.

New records of herbivory of Leucothyreus MacLeay, 1819 (Coleoptera: Scarabaeidae: Geniatini) on Cecropia Loefl. (Urticaceae) - (2024)

Daniel P. P. Aguiar, Matheus Bento

Volume: 6 - Issue: 0

Resumo. Species in the genus Cecropia Loefl. (Urticaceae) are important food sources for a handful of species belonging to the insect orders Orthoptera (grasshoppers), Lepidoptera (caterpillars), Hymenoptera (leafcutter ants), and Coleoptera (beetles).  Among the leaf chafer beetles, specimens of the scarab genus Leucothyreus MacLeay, 1819 (Scarabaeidae: Geniatini) have been barely recorded as defoliators of Cecropia spp., and information about the identity of the involved plant and beetle species is scarce and imprecise. The present paper records for the first time the incidence of two species of Leucothyreus on four species of Cecropia in Central Amazon (Brazil), with short behavioral notes regarding their feeding habits.

New records of the flower fly Lejops barbiellinii (Ceresa, 1934) (Diptera, Syrphidae) in the Atlantic Forest: integrating collection and citizen science data - (2024)

Danilo P. Cordeiro, Cássio Zocca, Natalia P. Ghilardi-Lopes

Volume: 6 - Issue: 0

Resumo. Citizen science provides valuable data on species diversity worldwide. In this note, we discuss how a scientist's opportunistic observations of biodiversity, recorded on a citizen science platform, have enriched our understanding of the geographic distribution of Lejops barbiellinii (Ceresa, 1934) (Diptera, Syrphidae), a flower fly native to Brazil's Atlantic Forest. We also compared the number and specificity of iNaturalist records for the five most species rich families of flies in Brazil, demonstrating the potential of this platform for data acquisition of species with external morphological diagnostic characters, as for many flower fly species. This type of contribution from voluntary citizens contributes to increasing the knowledge about geographical distribution and our collective knowledge about L. barbiellinii and other flies in the Atlantic Forest.

Observations of the scoliid wasp Campsomeriella annulata annulata (Fabricius, 1793) foraging on fallen Firmiana simplex flowers - (2024)

Kazuo Yamazaki

Volume: 6 - Issue: 0

Resumo. A scoliid wasp, Campsomeriella annulata annulata (Fabricius, 1793) (Hymenoptera: Scoliidae), was observed foraging on Firmiana simplex flowers that had fallen onto shrubs in an urban park in central Japan. The wasp inserted its glossa into the tubular corolla of each fallen flower, foraging from eight different fallen male flowers within five minutes before flying away. This finding suggests that scoliid wasps may engage in atypical flower visitation, or that foraging from fallen flowers could reduce interspecific competition for floral resources.

Oviposition of Panonychus ulmi (Koch, 1936) (Acari: Tetranychidae) in response of conspecific and heterospecific mites cues - (2024)

Priscila de A. Rode, Julia R. Schneider, Noeli J. Ferla

Volume: 6 - Issue: 0

Resumo. This study aimed to assess oviposition of Panonychus ulmi (Koch, 1936) (Acari: Tetranychidae) in response of conspecific and heterospecific mites cues on apple trees (Malus domestica Borkh: Rosaceae). The oviposition of P. ulmi was measured on apple tree leaves with the presence of webs, eggs, and other cues of phytophagous mites (Aculus schlechtendali (Nalepa, 1890) (Acari: Eriophyidae), P. ulmi, Tetranychus urticae Koch, 1936 (Acari: Tetranychidae), and Tetranychus ludeni Zacher, 1913 (Acari: Tetranychidae)). The presence of conspecific webs and cues increased the oviposition of P. ulmi, while the presence of A. schlechtendali and T. urticae webs and eggs and A. schlechtendali cues decreased oviposition. The oviposition increases in the presence of conspecifics suggesting that P. ulmi performs better in environments without heterospecific mites. On the other hand, the P. ulmi decreases in oviposition in presence of heterospecific mite cues suggesting a potential competitive displacement of tetranychid by eriophyid mites.
