Maria E. S. Valentim, Lanna L. G. S. O. Rocha, Gerane C. D. Bezerra-Silva, Márcio A. Silva

Volume: 7 - Issue: 0

Resumo. Brazil is a large producer of cucurbits; despite the productive advantage, the country still has a low insertion in the international market due to the quarantine restrictions imposed by the Anastrepha grandis (Macquart, 1846) (Diptera: Tephritidae) presence. In this context, we conducted a study using McPhail traps and fruit sampling for three consecutive harvests to investigate the presence of A. grandis in commercial watermelon cultivation located in the Irrigation District of the Coastal Plateau of Piauí, Northeast Brazil. Anastrepha grandis was not registered in the coastal plain of Piauí, demonstrating the potential to establish a Pest Free Area. For this purpose, developing a pilot project on a larger time scale covering several properties and municipalities in Piauí is necessary.

Another brick in the wall: new record and key to Anastrepha Schiner, 1868 (Diptera, Tephritidae) from Pará, Brazil - (2025)

Roberto A. Zucchi, Alexandre S. Araújo, Aprigio L. de Oliveira-Filho, Israel de S. Pinto, Mateus S. L. Aurélio, Marcoandre Savaris

Volume: 7 - Issue: 0

Resumo. Despite advances in studies on fruit flies belonging to the genus Anastrepha Schiner, 1868 (Diptera: Tephritidae) in the state of Pará, Brazil, over the past two decades, knowledge of their diversity remains incipient, particularly when considering the vast geographical expanse of the state. Only 35% of the documented species have been associated with their respective hosts. Anyway, for Anastrepha parishi Stone, 1942, which is reported for the first time in Pará State, all records of this species in Brazil have been associated with their designated hosts. In addition to this new record, we discuss the distribution of Anastrepha consobrina (Loew, 1873) in Pará, whose original description was based on specimens collected in the state in the early 19th century. Since then, A. consobrina has not been collected in Pará. A key to the 40 species of Anastrepha known in Pará is presented.

Ant nests found in mature pods of Cassia fistula L. and the extended phenotype of herbivores as house to opportunistic twig dwellers - (2025)

Felipe G. Gonçalves, Maycon R. Silva, Gustavo Tsujimoto, José M. S. Bento, Marcoandre Savaris

Volume: 7 - Issue: 0

Resumo. Ants can present specialized or opportunistic nesting habits; the latter not being restricted to a single or a narrow set of host species in an ecological interaction. Herein we report ant colonies belonging to seven species and four genera inside ripe pods of Cassia fistula L. (Fabaceae) with signs of previous occupation by herbivores. Among the species found nesting in pods previously excavated by phytophagous insects are Cephalotes targionii (Emery, 1894); Cephalotes eduarduli (Forel, 1912); Crematogaster aff. victima Smith, 1858 and Crematogaster sp. (Myrmicinae); Myrmelachista nodigera Mayr, 1887 (Hymenoptera: Formicidae: Formicinae); Pseudomyrmex gracilis (Fabricius, 1804) (Hymenoptera: Formicidae: Pseudomyrmecinae) and Tapinoma sp. (Hymenoptera: Formicidae: Dolichoderinae), all of which showed opportunistic behavior by using pods previously hollowed and holed by phytophagous insects. This is the first record of Cephalotes Latreille, 1802 ants nesting in structures other than trunks and branches.

Armadilha atrativa padronizada e de baixo custo para coleta de Diptera (Insecta) atraídos por substratos proteicos - (2025)

Alex S. B. de Souza, Nelson L. M. Fernandes

Volume: 7 - Issue: 0

Resumo. The use of baited traps is essential for sampling necrophagous Diptera Linnaeus, 1758 in both ecological and forensic studies. Ferreira's trap is a widely used model in Brazil; however, traditional versions can present logistical challenges under field conditions. This study proposes a simple, cost-effective modification to the original design, using standard plastic honey jars as the new apparatus. The modified trap is characterized by its portability, ease of assembly, and the ability to allow rapid specimen retrieval. The effectiveness of the modified trap was successfully demonstrated during field collections. The system is designed for use by a single researcher and has proven to enable efficient specimen capture comparable to that achieved with classical traps. This design is especially recommended for sampling blowflies and other Diptera attracted to decomposing organic matter.

Armored Scale Insects (Hemiptera: Diaspididae) on Dypsis lutescens and Phoenix roebelenii (Arecaceae) in Urban Environments of Costa Rica - (2025)

Minor V. Solano-Gutiérrez, Paul Hanson

Volume: 7 - Issue: 0

Resumo. Armored scales (Hemiptera: Diaspididae) were collected from Dypsis lutescens (H. Wendl) Beentje & J. Dransf., 1995, and Phoenix roebelenii O’Brien, 1889, in urban Costa Rica. Lopholeucaspis cockerelli (Grandpré & Charmoy, 1899), previously known only from intercepted plant material, was found on both palms (P. roebelenii—new host record). Pseudischnaspis bowreyi (Cockerell, 1893), also previously recorded only from interceptions, was identified on both species (new host records). Ischnaspis longirostris (Signoret, 1882) was identified on both palms, Selenaspidus articulatus (Morgan, 1889) on P. roebelenii (new host record), Hemiberlesia cyanophylli Signoret, 1869 on P. roebelenii (new host record) and D. lutescens, H. palmae (Cockerell, 1893) on P. roebelenii (new host record) and D. lutescens, Pinnaspis strachani (Cooley, 1899) on D. lutescens, Pinnaspis apidistrae (Signoret, 1869) on D. lutescens and P. roebelenii (new host record), Diaspis boisduvalii Signoret, 1869 on P. roebelenii, Chrysomphalus dictyospermi (Morgan, 1889) on both palms (new host records), Lepidosaphes gloverii (Packard, 1869) on P. roebelenii (new host record), and Aspidiotus destructor Signoret, 1869 on both palms. Among parasitoids, Aphytis sp. (Hymenoptera: Aphelinidae) was reared from C. dictyospermi and I. longirostris, and Signiphora sp. (Hymenoptera: Signiphoridae) from H. cyanophylli and I. longirostris. This is the first record of a species of Signiphora Ashmead, 1880 parasitizing I. longirostris. The identified armored scales are highly polyphagous and not exclusive to palms, highlighting the need for further research on their diversity and ecology, as well as their natural enemies, in tropical urban environments.

Comunidade de formigas associadas à cochonilha-rosada da cana-de-açúcar em sistemas convencional e orgânico de produção - (2025)

Maiara A. Cruz, Rodrigo M. Feitosa, Ana Lúcia B. G. Peronti, Nilza M. Martinelli

Volume: 7 - Issue: 0

Resumo.  In agroecosystems, the interaction between ants (Hymenoptera: Formicidae) and hemipterans can increase populations of these phytophagous insects, promoting injuries and damage caused by them to crops. The aim of this study was to list the species of ants associated with the mealybug Saccharicoccus sacchari (Cockerell, 1895) (Hemiptera: Pseudococcidae), classifying them according to their presence in the different parts of sugarcane plants. In addition, we verified whether the adopted cultivation system could alter the ant community associated with mealybugs. The experiment was carried out in 2018/19 agricultural harvest, in two sugarcane stands, variety CTC4, in conventional and organic system, both in the municipality of Jardinópolis, SP, Brazil. Ants were collected in the mealybug colonies fixed in different plant structures and sugarcane development stages, including preliminary inspections on the roots of clumps and during plant development, evaluating aerial structures: sprouts, tillers and stalks. Eighteen species of ants were recorded. From these, eight were recorded exclusively in the conventional system, two only in the organic system and eight ant species were common for both systems. It is noteworthy that, for each of the plant structures, clumps and stems, six species of ants occurred exclusively foraging in the mealybug colonies. For sprouting, mealybugs and ants were not observed. We conclude that the cultivation system adopted in the cane field seems to influence ant community associated with S. sacchari. These results can help us to advance in the knowledge about how associated ants can alter the infestation indices of the mealybug in sugarcane fields.

Confirmation of Acutaspis albopicta (Cockerell, 1898) (Hemiptera: Diaspididae) in Brazil: occurrence on baru (Dipteryx alata Vogel, Fabaceae), a native Cerrado plant species - (2025)

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

Volume: 7 - Issue: 0

Resumo. Recent research has been shown that Cerrado hosts a high richness of scale insects (Hemiptera: Coccomorpha) associated with native and exotic plants from different families and botanical species. This work aimed to report for the first time an association of an armored scale insect (Diaspididae), Acutaspis albopicta (Cockerell, 1898), with baru (Dipteryx alata Vogel, Fabaceae), a native tree from Cerrado biome, in Federal District, Brazil. Additionally, this is the first occurrence of this species of Diaspididae in Central Brazil. Acutaspis albopicta was first mentioned in Brazil in Rio de Janeiro, associated with Cocos nucifera (L.) (Arecaceae), but, until now, there was no evidence of its occurrence in the country. In this work, there is a confirmation of A. albopicta in Brazil, and macroscopic and microscopic descriptions and illustrations are presented.

First record of Brachymeria pandora (Crawford, 1914) and Conura aff. flavicans Spinola, 1837 (Hymenoptera, Chalcididae) in cocoon of Rothschildia erycina (Shaw, 1796) (Lepidoptera, Saturniidae): multiparasitoidism or hyperparasitoidism? - (2025)

Gilcélia M. Lourido, Marcelo T. Tavares, Amanda Galvão, Marcio L. de Oliveira

Volume: 7 - Issue: 0

Resumo. We report the first record of the parasitoid Brachymeria pandora (Crawford, 1914) (Hymenoptera, Chalcididae) emerging from a cocoon of Rothschildia erycina (Shaw, 1796) (Lepidoptera, Saturniidae). This interaction was observed on Eriotheca candolleana (K. Schum.) A. Robyns (Malvaceae), which also constitutes the first record of this plant as a host for R. erycina. These findings are from Alter do Chão, Santarém, state of Pará, Brazil. Additionally, a female of Conura aff. flavicans Spinola, 1837 (Hymenoptera: Chalcididae) was observed exhibiting oviposition behavior on the same cocoon, from which the pupa responded with a trembling defensive reaction, but no individuals of this species were obtained. However, no individuals of C. aff. flavicans emerged, and its role as a primary parasitoid of the moth or a hyperparasitoid of B. pandora is discussed.

First record of Megninia ginglymura (Mégnin, 1877) (Sarcoptiformes: Analgidae) in the state of Pernambuco, Brazil, associated with hen poultry systems - (2025)

Maria B. G. Duarte, Iasmyn V. C. Galvão, Lidia R. A. Silva, Juan S. D. Cáceres, Antônio A. Paz-Neto, Noeli J. Ferla, José W. S. Melo

Volume: 7 - Issue: 0

Resumo. Mites of the genus Megninia Berlese, 1883 (Sarcoptiformes: Analgidae) are known ectoparasites of birds in intensive production systems, however, their distribution in Brazil remains poorly documented. This study reports the first record of the feather mite Megninia ginglymura (Mégnin, 1877) (Sarcoptiformes: Analgidae) in the state of Pernambuco, Brazil. Samples were collected from two farms with different rearing systems: Vertical Automatic, Californian and Cage Free. Monthly surveys were conducted between January and November 2024, totalizing 11 collections. M. ginglymura appears to be prevalent among poultry farms in Brazil; however, limited efforts has been made to mitigate its impacts, primarily due to a lack of targeted research. Baseline studies such as this are essential for guiding future research aimed at characterizing populations in poultry systems and reducing the impacts caused by Megninia mites.

Gabriel R. Barros, Laura J. Gisloti, Francisca L. da C. Silveira, Érica C. Calvet

Volume: 7 - Issue: 0

Resumo. Passion fruit cultivation in Northeastern Brazil stands out in terms of both production and productivity when compared to other regions of the country. However, the incidence of arthropod pests during crop management poses a significant challenge. Among the various pest species, the presence of dipterans commonly known as flower bud flies, belonging to the genera Dasiops Rondani (1856) and Neosilba McAlpine (1962) (Diptera: Lonchaeidae), is particularly noteworthy. Both genera have been reported on plants in the Passifloraceae, with species from the genus Dasiops being primarily associated with the abscission of reproductive structures, which represents the main limiting factor in achieving high yields. In this context, the aim of this study was to identify the main species of flower bud fly present in passion fruit plantations in producing regions of the state of Ceará. To this end, five collections of infested flower buds were carried out. In Brazil, the species Dasiops inedulis Steyskal, 1980 has already been recorded in six states; this study represents the first record of the species in the state of Ceará.

Foraging Activity in Polybia striata (Fabricius, 1787) (Hymenoptera: Vespidae) - (2025)

Izabella Schaefer, Wilker Morais, Lucas R. Oliveira, Bruno C. Barbosa, Fábio Prezoto

Volume: 7 - Issue: 0

Resumo. Foraging ensures resource acquisition for feeding, nest construction, and colony maintenance in social wasps. This study examined the foraging activity and dripping behavior of Polybia striata (Fabricius, 1787) (Hymenoptera: Vespidae) in an urban environment, analyzing their correlation with temperature and humidity. Observations took place on the campus of the Federal University of Juiz de Fora, totaling 50 hours between January and February 2018. Every 30 minutes, departures and returns to the nest were recorded, along with climatic variables. Foraging activity peaked between 9:00 and 13:30, the hottest period of the day. The number of departures increased with temperature and decreased with humidity, suggesting that hottest conditions favor foraging while high humidity inhibits it. Always after rainfall, wasps engaged in dripping behavior, regurgitating small water droplets from the nest structure. This behavior occurred more frequently in the morning and was linked to nest maintenance. In addition to advancing knowledge of the species' ecology, this study may inform management strategies in urban areas.

If you seek, you will find: second record of Melanoloma viatrix Hendel, 1911 (Diptera, Richardiidae) in pineapple in Brazil and its distribution in the country - (2025)

Aprigio L. Oliveira-Filho, Israel S. Pinto, Hilda B. Luz, Thiago H. R. Pádua, Francisco Limeira-de-Oliveira, Ricardo Adaime, Marcoandre Savaris, Roberto A. Zucchi

Volume: 7 - Issue: 0

Resumo. The pineapple fly, Melanoloma viatrix Hendel, 1911 (Diptera, Richardiidae), is a pest in pineapple plantations in several South American countries. In Brazil, pineapple damage by M. viatrix was first reported in a commercial plantation in the state of Amapá. We report this pest from a single pineapple sample collected in the municipality of Itaituba, state of Pará, from a plantation operated under the family farming system. As in other South American countries, pineapple is the sole known host of M. viatrix. Examination of specimens deposited in two Brazilian collections revealed that, in addition to the states of Amapá and Pará, M. viatrix also occurs in the states of Maranhão, Tocantins, and Mato Grosso. However, no host information is known for the specimens deposited in collections; therefore, M. viatrix is known to damage pineapple only in Amapá and Pará. Given the extensive geographical distribution of the pest, surveys of host plants and sampling in other Brazilian pineapple-producing states are needed to establish effective management strategies and prevent the spread of the pest within Brazil.

Novos registros georeferenciados de Tityus serrulatus Lutz & Mello, 1922 (Scorpiones, Buthidae) para o estado do Mato Grosso, centro-oeste do Brasil - (2025)

Jessé M. Ribeiro Junior, Pablo M. Pazóti, Marielle C. Schneider, Marcos A. Carvalho, Christine Strüssmann

Volume: 7 - Issue: 0

Resumo. We present additional records of Tityus serrulatus Lutz & Mello, 1922 (Scorpiones: Buthidae) for the state of Mato Grosso, midwestern Brazil. The record of this scorpion species, which can cause mild to severe envenomation, significantly contributes to the knowledge of scorpionism in the state, as well as to the mapping of its distribution in the Brazilian territory. A morphologically similar species is abundant in the area - Tityus confluens Borelli, 1899 (Scorpiones: Buthidae), also presenting a general uniform yellow coloration - but is usually responsible for less severe scorpion accidents. The correct identification of both species by health agents and the general population may be relevant for the appropriate treatment of local scorpion sting cases.

Occurrence and symptom characterization of Oligonychus grypus Baker & Pritchard (Acari: Tetranychidae) in sugarcane - (2025)

Gabriel Ramos, Daniel Júnior de Andrade

Volume: 7 - Issue: 0

Resumo. The occurrence of phytophagous mites in Brazilian sugarcane crops has received limited attention but has increased over the past two decades. Among these mites, Oligonychus grypus Baker & Pritchard, 1960 (Acari: Tetranychidae), commonly known as the African sugarcane mite, is particularly noteworthy. Its populations have intensified, with high-density outbreaks associated with climate change and agricultural practices. In Brazil, this species was first identified in 2009 in the Piracicaba region of São Paulo. Under severe infestations, it causes extensive damage to leaf blades, producing yellowish to whitish spots that indicate its destructive potential. These injuries reduce crop yield and compromise the quality of raw material for industrial processing. This scientific note reports the occurrence of O. grypus in commercial sugarcane fields in the Ribeirão Preto region, São Paulo. It documents the symptoms and potential impacts on the crop, underscoring the importance of monitoring, given the economic significance of sugarcane production in Brazil.
