Modeling and updating the occurrence of Aedes aegypti in its southern limit of distribution in South America.

Aedes aegypti is the main vector of arboviruses in the world. This mosquito species is distributed from tropical to temperate regions. In Argentina, it has been reported in 20 out of 23 provinces and reaches its southernmost distribution in the world.

Winter survival of Aedes aegypti (Diptera: Culicidae) eggs at its southern limit distribution.

Aedes aegypti (L.) (Diptera: Culicidae) survives in the egg stage under unfavorable environmental conditions. In this study, we assessed the survival of Ae.

First report of a Copitarsia species (Lepidoptera. Noctuidae) damaging soybean crops, with identification key to most common pest species.

The genus Copitarsia Hampson (Lepidoptera. Noctuidae) includes agricultural pests of at least 48 crop plants and they are distributed from Mexico to southern South America. In South America, from Venezuela to Chile and Argentina, Copitarsia incommoda (Walker) is one of the most economic important species of the genus.

Global Potential Distribution of the South American Cutworm Pest Agrotis robusta (Lepidoptera: Noctuidae).

Invasive pest species can represent significant losses to the agricultural economy of a country. Assessing the potential distribution of known pest species could be an important tool to evaluate possible invasive threats globally. Agrotis robusta (Blanchard) is an endemic species of temperate areas of South America considered an important pest of seedlings of sunflower, dry bean, and potatoes.

The Granulate Cutworm (Lepidoptera: Noctuidae): Biological Parameters Under Controlled Conditions, Host Plants, and Distribution in the Americas.

Feltia subterranea (Fabricius), commonly known as the granulate cutworm, is a common species of owlet moths (Noctuidae) of major agricultural importance, widely distributed in Nearctic and Neotropical regions. This study was conducted to determine the species biological parameters, gather information about its larval host plants, and assess the agricultural significance of this species in the Americas. The viability of the egg, larval, pupal stages, and prepupal period was 98, 98, and 100%, respectively, under laboratory conditions.

Taxonomy of five neglected South American species of Dargida Walker (Lepidoptera: Noctuidae).

The taxonomy of five South American species of Dargida Walker currently allocated in Leucania Ochsenheimer (four species) and in Lasionycta Aurivillius (one species) is revised. Leucania roseilinea (Köhler, 1947), Leucania phaeoneura Hampson, 1913, Leucania mocoides Dognin, 1897, Leucania alboradiata (Hampson, 1905) and Lasionycta radiata (Köhler, 1966), are here combined with the genus Dargida Walker for the first time (comb. nov.

The austral-most record of the genus Haemagogus Williston (Diptera: Culicidae).

Introduction: The genus Haemagogus Williston is restricted to Central America and North and middle of South America and it includes numerous species of yellow fever virus vectors.

Methods: Adult female and larvae mosquitoes were collected using hand aspirators and dipper and pipette, respectively.

Results: The first record of a species of Haemagogus and particularly of Haemagogus spegazzinii was from La Pampa, Argentina.

Phylogeography of the gall-inducing micromoth Eucecidoses minutanus Brèthes (Cecidosidae) reveals lineage diversification associated with the Neotropical Peripampasic Orogenic Arc.

We investigated the molecular phylogenetic divergence and historical biogeography of the gall-inducing micromoth Eucecidoses minutanus Brèthes (Cecidosidae) in the Neotropical region, which inhabits a wide range and has a particular life history associated with Schinus L. (Anacardiaceae). We characterize patterns of genetic variation based on 2.

Resurgence of a forgotten Southern Brazil endemic species: taxonomic position, redescription, and spatio-temporal distribution of Schaus, 1929 (Lepidoptera: Noctuidae: Noctuinae).

The taxonomy of the hitherto unplaced taxon Porosagrotis carolia Schaus, 1929 is evaluated and the name is taken out of taxonomic limbo and combined with Feltia Walker, 1856. Feltia carolia comb. nov.

Revision of the Neotropical genus Eschatocerus Mayr (Hymenoptera, Cynipidae, Eschatocerini) with biological notes and the first description of the terminal larva.

The gall wasp genus Eschatocerus (Hymenoptera, Cynipidae, Eschatocerini), a cynipid genus of gall inducers on Prosopis and Acacia species (Fabaceae), endemic to southern South America, is revised. Complete descriptions of the external morphology of the genus and its three known species, illustrated with scanning electron photographs, are given for the first time, and an updated key for the identification of the species is provided. The biology of the species of Eschatocerus and their galls is described.

A revision of the South American genus Metecia Snellen (Lepidoptera, Noctuidae, Noctuinae).

The genus Metecia Snellen (Noctuidae. Noctuinae) from Southern Argentina and Chile is redescribed and three species are recognized: M. cornifrons Snellen, M.

Agrotis Ochsenheimer (Lepidoptera, Noctuidae): a systematic analysis of South American species.

The genus Agrotis Ochsenheimer, 1816 (Lepidoptera, Noctuidae) contains about 300 described species distributed worldwide, excepting the Poles. For South America 93 species have been described. Different diagnostic characters have been proposed for species from the northern Hemisphere, mostly from male genitalia.

Redescription of Dicranoses capsulifex Kieffer and Jörgensen (Lepidoptera: Cecidosidae) with description of the immature stages and biology.

Dicranoses capsulifex Kieffer and Jörgensen (Lepidoptera: Cecidosidae) is a gall inducing moth associated with Schinus fasciculatus (Griseb.) (Anacardiaceae), with a known distribution restricted to Argentina. It undergoes a one year life cycle (univoltine), with leaf-like galls, and adult with only a half day life span.
