RESUMO Lagartas de Automeris liberia (Lepidoptera: Saturniidae) são importantes desfolhadoras da palma de óleo, Elaeis guineensis (Arecaceae) nas Américas Central e do Sul. A família Tachinidae (Diptera) compreende moscas parasitoides de muitos insetos-praga, principalmente da ordem Lepidoptera. Contudo, o registro de hospedeiros de taquinídeos ainda é relativamente escasso. No presente trabalho, relatamos a ocorrência de Belvosia sp. aff. williamsi (Diptera: Tachinidae: Exoristinae: Goniini) e Leptostylum oligothrix (Diptera: Tachinidae: Exoristinae: Blondeliini) parasitando lagartas de A. liberia em E. guineensis no município de Tailândia, Pará, Brasil. Trata-se do primeiro registro do parasitismo de A. liberia por Leptostylum no Brasil, bem como o primeiro por Belvosia no mundo.

ABSTRACT Automeris liberia (Lepidoptera: Saturniidae) caterpillars are important defoliators of the African oil palm, Elaeis guineensis (Arecaceae) in Central and South America. The family Tachinidae (Diptera) comprises flies that are parasitoids of many insect pests, mainly from the order Lepidoptera. However, host records for tachinids are still relatively scarce. In the present work, we report the occurrence of Belvosia sp. aff. williamsi (Diptera: Tachinidae: Exoristinae: Goniini) and Leptostylum oligothrix (Diptera: Tachinidae: Exoristinae: Blondeliini) parasitizing caterpillars of A. liberia in E. guineensis in the municipality of Tailândia, state of Pará, Brazil. This is the first record of the parasitism of A. liberia by Leptostylum in Brazil, as well as by Belvosia in the world.

ABSTRACT The rose tortrix moth, Archips rosana (L.) (Lepidoptera: Tortricidae), is a pest that causes serious crop losses in apple orchards throughout the world. In this study, the population dynamics of A. rosana and its associated parasitoids were investigated in two provinces of Western Turkey (Denizli and Usak) in 2018 and 2019. A total of 318 egg masses, 300 larvae, and 129 pupae were collected from the survey areas. Although no parasitoids were detected in egg masses, ten parasitoid species belonging to Braconidae, Chalcididae, and Ichneumonidae (Hymenoptera), and Tachinidae (Diptera), were reared from the samples of larvae and pupae. Phytodietus astutus (Gravenhorst) (Ichneumonidae) was the most abundant parasitoid species, with a relative abundance of 35.1%, followed by Itoplectus maculator (Fabricius) (Ichneumonidae) represented by 27% of the recovered parasitoids. Moreover, P. astutus and Scambus inanis (Schrank) (Ichneumonidae) reared from the samples are the first records from Turkey, while Cotesia glomerata (L.) (Braconidae), Exochus sp.(Ichneumonidae), and Nemorilla maculosa (Meigen) (Tachinidae) are the first records from A. rosana. Using pheromone traps in the apple orchards, the first adult of A. rosana was caught on May 24 in Civril (Denizli) and on May 30 in Sivasli (Usak) in 2019.

Resumen Desde el 2009 se ha evidenciado en las plantaciones de cacao del valle de Zarumilla (Tumbes, Perú), la presencia de un insecto plaga de especie aún no identificada, cuyas larvas perforan los tallos y frutos del cacao, y afectan su valor comercial por la invasión de microorganismos patógenos secundarios. Este trabajo de investigación que se realizó de marzo a agosto del 2014 tuvo como objetivos identificar y describir morfológicamente al barrenador del fruto y tallo del cacao, no reportado para las condiciones de este valle. Las recolectas se realizaron en campos cacaoteros del valle de Zarumilla y la crianza de los estados inmaduros, en el laboratorio de Entomología de la Universidad Nacional de Tumbes. Los resultados permitieron determinar que la especie cuya larva perfora los tallos y frutos del cacao es Carmenta theobromae. Se describen las principales características morfológicas de esta especie, referente a los estados de huevo, larva, pupa y adulto de ambos sexos. Además, del material biológico recolectado en campo durante el muestreo, se identificaron dos parasitoides a nivel de familia, un díptero Tachinidae recuperado de larvas y un himenóptero Chalcididae a partir de pupas. Se concluye que la especie que barrena los frutos de cacao en las plantaciones del valle de Zarumilla es C. theobromae. El presente estudio servirá de base para realizar futuras investigaciones de la biología y comportamiento en relación con los factores ambientales y determinar si esta especie tiene preferencia por determinados clones de cacao sembrados en la zona.

Abstract Since 2009, the presence of a pest insect of an unidentified species whose larvae pierce the stems and fruits of the cocoa plant, affecting the commercial value of the fruits by the invasion of secondary pathogenic microorganisms, has been demonstrated in the cocoa plantations of the Zarumilla valley, (Tumbes, Peru). This research work was carried out from March to August 2014 in order to identify and morphologically characterize the borer of the fruit and stem of the cocoa plant not reported for the conditions of this valley. The collections were made in cocoa fields of the Zarumilla valley and the breeding of immature states was carried out in the Entomology laboratory of the National University of Tumbes. The results made it possible to determine that the species whose larva pierces the cacao stems and fruits is Carmenta theobromae. The main morphological characteristics of this species are described, referring to the egg, larva, pupa and adult stages of both sexes. In addition, from the biological material collected in the field during the sampling, it was possible to identify two parasitoids at the family level, a dipteran Tachinidae recovered from larvae and a hymenopteran Chalcididae recovered from pupae. It is concluded that the species that burrows cocoa fruits in cocoa plantations in the Zarumilla Valley is C. theobromae. The present study will serve as the basis for biology and behavioral studies of in relation to environmental factors and to determine if this species has a preference for certain cocoa clones planted in the valley.

Resumen Las moscas taquínidas son importantes parasitoides que regulan naturalmente la densidad poblacional de diversas plagas agrícolas. Este trabajo de investigación tuvo por objetivo identificar a los parasitoides Tachinidae emergidos de la chinche Euschistus heros procedente de recolectas hechas en cultivo de soja de la localidad de Fortuna, municipio de Pedro Juan Caballero, Departamento de Amambay, Paraguay. Los insectos fueron criados y mantenidos en el laboratorio de Protección Vegetal, división Entomología de la Facultad de Ciencias Agrarias, de la Universidad Nacional de Asunción. Se observó que de las chinches surgieron larvas y pupas, de las cuales emergieron moscas (n = 7). Los especímenes en tubos de vidrio se conservaron en alcohol 70 % y se enviaron para su identificación y clasificación taxonómica al laboratorio de Sistemática y Biogeografía de Diptera del Departamento de Zoología del Instituto de Biociências de la Universidad de São Paulo, Brasil. La mosca parasitoide emergida fue identificada como Gymnoclytia (Diptera: Tachinidae), siendo el primer registro para el cultivo de soja en Paraguay, un importante agente de control biológico que puede favorecer el equilibrio natural de la densidad poblacional de E. heros.

Abstract Tachinid flies are important parasitoids of many pests. The purpose of this study was to identify the parasitoid emerged from the brown stinkbug Euschistus heros (Hemiptera: Pentatomidae) from collection done at the town of Fortuna, Pedro Juan Caballero municipality, Amambay State, Paraguay. The bugs were collected in the field on soybeans and were taken to the laboratory for breeding, feeding and maintenance, and checked for the presence of tachinids at the Entomological and Crop Protection Department of the Faculty of Agricultural Sciences, National University of Asuncion. The insects were inspected daily, and the emergence of pupating larvae was observed from them. The fly puparia were maintained until the emergence of the adult fly (n = 7). Specimens were kept in glass tubes with a 70 % alcohol solution and then sent to the laboratory of Systematic and Biogeography of Diptera at the Zoology Department, Biosciences Institute, University of de São Paulo, Brazil for identification. The parasitoid fly that emerged was identified as Gymnoclytia (Diptera: Tachinidae), the first report for soybean in Paraguay, an important natural biological control agent that might balance the population density of E. heros.

ABSTRACT A new genus and species of Tachinidae (Diptera), Paxiximyia sulmatogrossensis n. gen. and n. sp. , and its puparium are described. It was reared from the walking stick, Urucumania borellii (Giglio-Tos, 1897), collected in Aquidauana, Mato Grosso do Sul, Brazil.

Resumen Trigonospila unicaldasi nueva especie, es registrada por primera vez para la ciencia con el propósito de diferenciarla de otras especies que son de escasa ocurrencia en las Américas. Para lograr este objetivo se consideraron las estructuras clave del adulto utilizando la técnica de Microscopía Electrónica de Barrido (MEB) para su completa descripción. La especie se encontró parasitando adultos de Compsus sp. (Coleoptera: Curculionidae) asociados a cultivos de cítricos en la zona cafetera central de Colombia. El interesante fenómeno simbiótico de control mencionado en este documento se considera un caso poco usual en la biología de los Tachinidae debido a que solo del 5% al 10% de estos parasitan especies en estado adulto.

Abstract Trigonospila unicaldasi new specie, is described for the first time for science. In order to differentiate it from other rarely occurring species in the Americas, key characteristics of the adult were identified through scanning electron microscopy. The species was found parasitising adult weevils of the genus Compsus sp. (Coleoptera: Curculionidae) associated with citrus crops in the central coffee-growing region of Colombia. The interesting symbiotic phenomenon of control described in this paper is considered unusual in the biology of Tachinidae given that only 5-10% of the family parasitise their hosts at the adults stage.

Abstract In the state of Mato Grosso do Sul, which is composed by four macroregions, Cerrado, Chaco, Atlantic Forest and Pantanal, there are 39 species and 24 genera of Tachinidae based on the literature. The subfamily Tachininae, with 15 species occurring in the State, has the highest representativeness, while the other subfamilies, Exoristinae, Phasiinae, and Dexiinae, with respectively 14, 7 and 3 species.

ABSTRACT The coexistence of species with similar ecological requirements (food, space, time) has typically drawn attention of researchers because competition for resources is expected to be high. The diet and microhabitat occupation of two morphologically and ecologically similar species of Hylidae (Anura), Dendropsophus microcephalus and Scarthyla vigilans, were analyzed at a locality in north-western Venezuela, with the aim of addressing the potential for space and food competition between them. Diet was estimated through the analysis of stomach contents and microhabitat occupation was estimated through recordings of perch type, height and horizontal distance to water. Thirty-six prey categories (32 families, 4 orders) of arthropods were identified: 30 categories in D. microcephalus and 21 categories in S. vigilans. The most important prey (RII) in D. microcephalus were Agelenidae (11.1%), Tachinidae (9.32%) and Lepidoptera-larvae (7.96%). Gryllidae (14.13%), Cicadidae (9.1%), Cicadellidae (8.3%) and Delphacidae (8.02%) were the most important in S. vigilans. Diet overlap was relatively low (0.32). Both species have relatively generalist diets. Both species occupied the same type of perches (leaves and stems of Dicotyledons and Monocotyledons) and heights (average: S. vigilans, 24 ± 16.2 cm; D. microcephalus, 22.7 ± 9.5 cm). The potential for space competition is high if perches are limited and food competition is expected to be low.

RESUMEN La coexistencia de especies con requerimientos ecológicos similares (alimento, espacio, tiempo) típicamente ha atraído a los investigadores porque se espera que la competencia por recursos sea alta. La dieta y la ocupación de microhábitat de dos especies morfológica y ecológicamente similares de Hylidae (Anura) se analizaron en una localidad al noroeste de Venezuela, con el objetivo de evaluar el potencial para competencia entre ellas. La dieta se estimó a través del análisis de los contenidos estomacales y la ocupación del microhábitat por medio de registros del tipo y altura de la percha y la distancia horizontal al agua. Se identificaron 36 categorías de presa (32 familias, 4 órdenes); 30 en D. microcephalus y 21 en S. vigilans. Las presas más importantes (RII) en D. microcephalus fueron Agelenidae (11,1%), Tachinidae (9,32%) y Lepidoptera-larva (7,96%). Gryllidae (14,13%), Cicadidae (9,1%), Cicadellidae (8,3%) and Delphacidae (8,02%) fueron las más importantes en S. vigilans. Ambas especies tienen dietas relativamente generalistas. La superposición de las dietas fue relativamente baja (0,32). Ambas especies ocuparon el mismo tipo de perchas (hojas y tallos de dicotiledóneas y monocotiledóneas) a las mismas alturas. El potencial para la competencia por espacio es alto si las perchas fuesen escasas, pero se espera que la competencia por el alimento sea baja.

RESUMO: Este estudo investigou o parasitismo natural de Mythimna sequax Franclemont, 1951, em uma lavoura de trigo, durante a safra 2008. No total, foram capturadas 237 lagartas, registrando-se um parasitismo de 10,12%. As espécies de taquinídeos Winthemia trinitatis (Thompson, 1963), Winthemia tricolor (Wulp, 1890), Lespesia aletiae (Riley, 1879) e Lespesia archippivora (Beneway, 1963) são registrados pela primeira vez parasitando a lagarta-do-trigo no Brasil. Adicionalmente, dois gêneros de parasitoides foram identificados, um taquinídeo Peleteria sp. (Robineau-Desvoidy, 1830) e um ichneumonídeo Ophion sp. (Fabricius, 1798). Este estudo registra pela primeira vez a ocorrência de quatro espécies de parasitoides em M. sequax no Brasil, e estudos adicionais são necessários para promover a conservação desses parasitoides no agroecossistema, assim como o desenvolvimento de programas de controle biológico para o manejo da lagarta-do-trigo.

ABSTRACT: This study investigated the natural parasitism of Mythimna sequax Franclemont, 1951, in wheat during the crop season of 2008. In total, 237 larvae were captured, of which 10.12% were parasitized. The Tachinidae species Winthemia trinitatis (Thompson, 1963), Winthemia tricolor (Wulp, 1890), Lespesia aletiae (Riley, 1879), and Lespesia archippivora Beneway, 1963 are reported for the first time parasitizing the wheat armyworm in Brazil. In addition, two other genus of parasitoids were identified, one Tachinidae Peleteria Robineau-Desvoidy, 1830 and one Ichneumonidae Ophion (Fabricius, 1798). This study reported for the first time four Tachinidae species parasitizing W. sequax, and further studies are needed to promote the conservation of these parasitoids in agroecossystem and development biological control programs for management of the wheat armyworm.
