Se realizaron 20 muestreos cada 15-20 días, entre setiembre de 2014 y febrero de 2015, excepto en julio-agosto de 2015 por ausencia de las plantas estudiadas. Las muestras consistieron en la extracción de 30 flores de Trifolium repens L. (Fabaceae), Commelina communis L., (Commelinaceae), Bidens pilosa L., Taraxacum officinale L. (Asteraceae), Solanum nigrum L. (Solanaceae), ubicadas debajo de la canopia de 10 árboles seleccionados al azar. Los tisanópteros obtenidos fueron identificados sobre la base de preparaciones microscópicas, las que se encuentran depositadas en la colección del INBIAL-UNJu y en el laboratorio de Entomología, EEA-INTA Famaillá. Se registraron 15 especies de las siguientes familias: Aeolothripidae (Franklinothrips tenuicornis), Thripidae (Dinurothrips vezenyii Bagnall, Neohydatothrips sidae Crawford JC, Arorathrips mexicanus (Crawford DL.), Chaetanophothrips orchidii, Frankliniella australis Morgan, Frankliniella curta Moulton, Frankliniella difficilis Hood, Frankliniella gemina Bagnall, Frankliniella occidentalis (Pergande), Frankliniella oxiura Bagnall, Frankliniella setipes Bagnall, Frankliniella schultzei (Trybom), y Phlaeothripidae (Haplothrips gowdeyi (Franklin) y Haplothrips sp.). Con el presente aporte se cita por primera vez para la Argentina a N. sidae y se amplía la distribución de F. difficilis, F. curta, A. mexicanus y H. gowdeyi en el país. El complejo de tisanópteros estuvo integrado por especies fitófagas y una depredadora (Franklinothrips tenuicornis Hood). La detección de Ch. orchidii en la vegetación espontánea confirma la necesidad de realizar estudios precisos que aborden el rol ecológico que estas plantas puedan tener en el mantenimiento de las poblaciones de insectos perjudiciales y de sus enemigos naturales.

Agardh) Comes, "tabaco virginia". Se diseñó un muestreo al azar de hojas (órganos cosechables), de frecuencia quincenal y en dos establecimientos productivos, ubicados en el departamento El Carmen (Jujuy, Argentina), durante las campañas 2012/2013 y 2013/2014. Sobre la base de los muestreos del primer año y aplicando los parámetros calculados de la ecuación de Taylor, se determinó el número mínimo de hojas a muestrear para conseguir errores inferiores o iguales al 20%.

Despite the numerous works on Ephemeroptera around the world there is no information about mayflies in urban environments. The aim of this study is to determine the diversity and abundance of mayflies recorded in the city of San Salvador de Jujuy, Argentina. The study was conducted in 32 homes of the city from November 2012 to October 2013. Two types of samplings were conducted: diurnal (with tweezers and brushes) and nocturnal (with light trap). The Ephemeroptera order is present in most of the neighborhoods of San Salvador de Jujuy because they are located near water bodies. There were 35 specimens belonging to seven species grouped into six genera and three families. The genera Baetodes Needham & Murphy and Leptohyphes Eaton were the most abundant, particularly during the rainy season. The results obtained in the present study represent the first contribution to the knowledge of Ephemeroptera present in synanthropic environments.

Thysanoptera (Insecta)-Vicia faba (Fabaceae) association in Prepuna and Puna in Jujuy, Argentina.... more Thysanoptera (Insecta)-Vicia faba (Fabaceae) association in Prepuna and Puna in Jujuy, Argentina. The different phenological stages of Vicia faba provide food resources and substrates for the development of a significant diversity of insects. This study aimed to identify the complex of anthophyllous thrips, analyze the species population fluctuations, to obtain some bioecological aspects and the role they play in this association. The study and sampling was conducted during the flowering-fruiting bean crop stages in two phytogeographical regions of Jujuy: Prepuna (2 479m asl) on a weekly basis, from October-December 1995-1996 and Puna (3 367m asl) every two weeks, from December 2007-March 2008. Each sample consisted of 25 flowers taken at random; only at Prepuna a complementary sampling of three hits per plant (n=10 plants) was conducted. Observations were made on oviposition sites, admission to the flower, pupation sites, feeding behavior and injuries caused. In Prepuna, the Thysanoptera complex consisted of Frankliniella australis, F. occidentalis, F. gemina, F. schultzei and Thrips tabaci; in Puna, the specific diversity was restricted to F. australis and F. gemina. Although the planting-harvest period in both areas did not match, the fluctuations in populations showed the same pattern: as flowering progressed, the number of thrips coincided with the availability of food resources. In both areas, F. australis was the dominant species and maintained successive populations; it layed eggs in flower buds, and larvae hatched when flowers opened; feeding larvae and adults brought about silvery stains with black spots. In Prepuna, F. australis went through the mobile immature stages on flowers, while quiescent stages were on the ground; in the Puna, all development stages took place within the flowers. Thrips tabaci, F. shultzei, F. occidentalis and F. gemina were temporary and opportunistic in Prepuna, while the presence of F. gemina was sporadic in Puna. The number of Thysanoptera species associated with beans cultivation in Argentina has increased.

The study was carried out on a commercial farm in Las Pampitas, located in the Perico valleys, Jujuy province (Argentina). Floral visitors and other arthropods were sampled and identified, and their diversity was analyzed. The samples of insects selected to obtain the pollen carried were processed following the acetolysis technique. The potential pollinators of the strawberry crop were estimated by calculating the pollination probability index. The floral visitors corresponded to representatives of Hymenoptera, Diptera, Hemiptera, Lepidoptera, Coleoptera and even Araneae. Apis mellifera L. was the most frequent floral visitor and presented more strawberry pollen than other selected insects. The pollination probability index estimated that this species had a high probability of being a pollinator. Other pollinators such as Allograpta exotica Wiedemann, Halictidae, Meliponini and even Thripidae could complement the action of the honeybee. This is the first contribution to the knowledge of the pollination of F. ananassa in the agroecosystems of Jujuy.

We also describe and illustrate the morphological characteristics that differentiate them. Gynaikothrips ficorum produc- es leaf galls form of folded sheets in Ficus microcarpa L. and G. uzeli in Ficus ben- jamina L. The specimens of G. ficorum were collected from the locality of Esperanza (Santa Fe) and G. uzeli from Libertador General San Martin (Jujuy).

We expected that this species had a generalised pollination system, with moths and diurnal visitors as the primary pollinators. To test this, we studied the floral biology, breeding system and floral visitors of this species and the effectiveness of nocturnal and diurnal visitors. Floral biology was defined based on floral morphology, floral cycle and nectar production of the flowers. The breeding system and relative contributions of diurnal and nocturnal visitors to fruit and seed set were analysed through field experiments. E. terscheckii flowers opened at sunset and closed the following day. The peak of nectar production occurred at midnight. Flowers were determined to be self-incompatible. Moths, bees and birds were identified as floral visitors. Moths were the most frequent visitors at night, whereas bees were the most frequent visitors during the day. Fruit production by diurnal pollinators was less than that by nocturnal pollinators; among all floral visitors, moths were the most effective pollinators. We have demonstrated for the first time that moths are the primary pollinators of columnar cacti of the genus Echinopsis. Our results suggest that moths might be important pollinators of columnar cactus species with nocturnal flowers in the extra-tropical deserts of South America.
