Here we report on the first peculiar detection of the spotted-winged drosophila, Drosophila suzukii (Matsumura) on Martín García Island, a wildlife refuge located in the Río de la Plata estuary, Argentina. Flies were collected using banana baited traps fermented with live yeast, in sandy areas with abundant presence of cactus in the interior of the island. The absence of cultivated host plants, e.g., fruit crops, and the small population of humans inhabiting the island make the presence of D. suzukii in this wildlife refuge unexpected. Previous detection of this fly in South America happened mostly within commercial fruit orchards and/or neighboring fields.
在这里，我们报告了在阿根廷Río de la Plata河口的一个野生动物保护区Martín García岛上首次发现的斑点翼果蝇，drosophila suzuki (Matsumura)。在该岛内陆仙人掌丰富的沙地地区，使用用活酵母发酵的香蕉诱捕器收集苍蝇。由于缺乏栽培的寄主植物，如水果作物，以及居住在岛上的人口较少，使得铃木氏弓形虫在这个野生动物保护区的出现出乎意料。以前在南美洲发现的这种苍蝇主要发生在商业果园和/或邻近的田地里。

The bee fly Toxophora aurea Macquart is reported for the first time in Argentina. One single specimen of this species was reared from a nest of Isodontia costipennis (Spinola) (Hymenoptera: Sphecidae) in the province of Formosa and others were captured in southern Misiones province, and others housed in entomological collections from the provinces Chaco, Santiago del Estero and Santa Fe. Data about the biology of Toxophora leucon Séguy from individuals reared in nests of Cyphomenes anisitsii (Brèthes), Pachodyneurs guadulpensis (Saussure) and Zethus dicomboda (Spinola) (Hymenoptera: Vespidae: Eumeninae) in the province of Formosa are also reported. These are the first data about the reproductive ecology of these parasitic flies in Argentina.

A new species of Plebeia Schwarz (Hymenoptera: Apidae) from Argentina is described and illustrated. Plebeia mansita Alvarez & Rasmussen sp. nov. occurs in the extreme northwest of the country and is restricted to the biogeographic province of the Yungas, where it is found at altitudes above 1,000 m. Observations on behavior, biology and nesting substrates of the new species are presented.

Asthenochrysa viridula Adams, 1978 (Chrysopidae: Nothochrysinae) is a neotropical species. Until now, this species was known from only a few specimens: the holotype female from Misiones, a province in northeastern Argentina and a male and two females from the states of Minas Gerais and Espírito Santo in Brazil. In this contribution, A. viridula is reported for the first time from Tucumán, a province located in northwestern Argentina and also from Santa Cruz, an eastern department in Bolivia.

White-backed planthopper, Sogatella furcifera Horváth (Hemiptera: Delphacidae) is a migratory and serious pest of rice crop worldwide including Pakistan. The current experiment was carried out to assess the antixenosis and antibiosis level of fifteen rice genotypes against S. furcifera under greenhouse conditions. In antixenosis studies, proportion of nymphs and adults settled was recorded in relation to control. Less preferred varieties by nymphs were RPP49 (3.80), N22 (5.60), IR 64 (6.20), IR 72 (6.60), Basmati Pak (6129) (5.40), and Super Basmati (5.00) as compared to TN1 (12.00). Lower number of eggs were laid on RPP49, N22, IR 64, Super Basmati and PKBB 8. Based on feeding marks the genotypes ranked from highest to lowest as RPP49, N22, IR 64, IR 72 and Basmati Pak. In antibiosis tests, RPP49, N22, IR64, IR 72, Super Basmati and Basmati Pak varieties performed well as compared to TN1. Minimum feeding rate (47.8 mm2) was recorded on RPP49 followed by N22, IR 64, IR74, Basmati Pak, Super Basmati, PKBB 8, PK 10684 and PK 10436 as compared to TN1(470.8 mm2). The results revealed that RPP49 emerged as the new resistant source against S. furcifera. Super Basmati, Basmati Pak have shown a moderate level of resistance while PKBB 8, PK 10684 and PK 10436 are new varieties with a moderate level of resistance to S. furcifera which can be used as resistance source in breeding programs against S. furcifera.

The sanitary important scorpion species Tityus trivittatus Kraepelin (Scorpiones: Buthidae) is reported for the first time from General Pico, La Pampa province. Specimens examined in this work were obtained in domiciliary environments. This represents a considerable expansion to the South of the distributional range of the species and the genus.

Agroecosystems produce profound alterations on the structure and functioning of the original environment, mainly due to the reduction of biodiversity. Flower flies (Diptera: Syrphidae) are potentially useful organisms for the diverse ecosystem services they provide. We studied syrphids collected in a Pampean agroecosystem to assess richness, abundance, host plants, and the ecosystem services they could offer. Flower flies were represented by three subfamilies, eight tribes, 17 genera, and 26 species/morphospecies. Adults of these flies visited flowers of 44 species of wild and/or cultivated plants and exhibited a generalist interaction pattern. Larvae of the most abundant species were predators (mainly soft-bodied Hemiptera) and/or decomposers/aquatic filters. Only one species was pollinivorous. Our results, together with the scarce published bibliography, suggest that the syrphid communities of the highly modified Pampean region are composed of a few very abundant species and many rare or low representative species.
