ABSTRACT
ABSTRACT Asphondylia hancorniae, sp. n. (Diptera, Cecidomyiidae) is described and illustrated. This species was collected in Atlantic Forest and Caatinga domains in Bahia State (Northeastern Brazil). It induces galls on fruits of Hancornia speciosa Gomes (Apocynaceae), a plant native to Brazil. Asphondylia hancorniae is compared to other congeneric species which induce galls on Apocynaceae.
ABSTRACT
ABSTRACT Asphondylia maricensis Maia & Couri, 1992 (Diptera, Cecidomyiidae) was described based on female and larva of third instar. Through fieldworks carried on the type locality, Maricá (RJ, Brazil) and rearing in laboratory, pupal exuvia was obtained and described for the first time. Its morphology indicates that the species belongs to Bruggmanniella Tavares, 1909. Therefore, a new combination is proposed, Bruggmanniella maricensis (Maia & Couri, 1992).
ABSTRACT
ABSTRACT Zalepidota distincta sp. nov. (Diptera, Cecidomyiidae) is described based on male, female, pupa and larva morphological characters. The new species induces galls on Piper vicosanum (Piperaceae), an endemic plant to Brazil. Types (mounted on slides) were deposited in the Entomological Collection of the Museu Nacional/Universidade Federal do Rio de Janeiro. Illustrations of the most relevant morphological characters are provided. The new species has some morphological characters that differ from those of the genus diagnosis. Therefore, the concept of Zalepidota was broadened.
ABSTRACT
Resumen Las regiones desérticas costeras del Pacífico de Perú y Chile albergan especies de Prosopis (Leguminosae: Mimosoideae), árboles bien adaptados a las condiciones del desierto y con funciones clave en los ecosistemas de bosques secos. Entre el 2001 y 2017, Prosopis en Perú ha sufrido una extensiva defoliación y muerte regresiva, con la consecuente deforestación y disminución de la producción de vainas de algarrobo. Aquí, se reporta una nueva especie de insecto plaga del bosque de Prosopis en Perú: Enallodiplosis discordis Gagné 1994 (Diptera: Cecidomyiidae), una feroz especie defoliadora que contribuye a la mortalidad generalizada de Prosopis. Se proporciona un análisis de la taxonomía larvaria de E. discordis, ciclo de vida y la infestación ocurrida después de El Niño Oscilación del Sur (ENSO) 1998/99. Su dispersión, distribución y ecología es examinada utilizando distintas líneas de evidencia. Durante casi dos décadas de trabajo de campo, se observó la muerte regresiva del bosque de Prosopis devastando los medios de vida rurales y los servicios de los ecosistemas en las regiones de las tierras bajas del sur (Ica), el centro y el norte de la costa peruana (Lambayeque, La Libertad, Piura). El colapso en la producción de vainas de Prosopis (algarroba, huaranga) y miel también fue registrada. Las notas complementarias proporcionan observaciones sobre: (i) el desarrollo de la plaga y el cambio de uso de la tierra y el clima, (ii) el control biológico y físico de E. discordis, (iii) la polilla Melipotis aff. indomita (Lepidoptera: Noctuidae) como defoliador concurrente de Prosopis.
Abstract The coastal desert of Peru and Chile is home to Prosopis (Leguminosae: Mimosoideae) tree species that are exceptionally well-adapted to the hyperarid conditions and keystone in dry-forest ecosystems. From 2001 to 2018, Prosopis in Peru have suffered widespread defoliation and die-back, with consequent deforestation and collapse in pod production. This paper reports a new insect plague species of Prosopis forest in Peru: Enallodiplosis discordis Gagné 1994 (Diptera: Cecidomyiidae) as a fiercely defoliating agent contributing to widespread Prosopis mortality. An analysis of E. discordis larval taxonomy, life cycle and plague infestation, following El Niño Southern Oscillation (ENSO) 1998/99 is provided. Using distinct lines of evidence, its spread, distribution, and ecology are examined. Over two decades of fieldwork, Prosopis forest die-back and loss was observed devastating rural livelihoods and ecosystem services across lowland regions of southern (Ica), central and northern coastal Peru (Lambayeque, La Libertad, Piura). The collapse in production of Prosopis pods (algarroba, huaranga) and honey was recorded. Supplementary notes provide observations of: (i) plague development, changing land-use and climate, (ii) biological and physical control of E. discordis, (iii) the moth Melipotis aff. indomita (Lepidoptera: Noctuidae) as a concurrent defoliator of Prosopis.
ABSTRACT
Clinodiplosis cecropiae Proença & Maia a new species of Cecidomyiidae (Insecta: Diptera) is described and illustrated herein (larva, pupal exuviae, male and female). Samples of gall and host plant were collected in Amazon Rainforest areas, in Monte Negro municipality, Rondônia state, Brazil. The galler was obtained by rearing in laboratory and the specimens were mounted on microscope slides. The type material is deposited in the Cecidomyiidae collection of Museu Nacional/Universidade Federal do Rio de Janeiro. The new species induces globoid galls on leaf petiole of Cecropia sp. (Urticaceae). This is the first record of a Clinodiplosis species inducing galls on Urticaceae plants.(AU)

ABSTRACT Galls on Bauhinia cupulata (Fabaceae) were investigated in two physiognomies of the Cerrado, riparian and dry forest, in the municipality of Barreiras (Western Bahia, Brazil) from October 2012 to July 2014. Four insect gall morphotypes were found. They were characterized based on shape, color, indumentum, plant organ of occurrence and galling taxon. A new galling species, Schizomyia barreirensis, is described, illustrated (larva, pupa, male, female and gall) and compared to other Neotropical congeneric species.

ABSTRACT
Bruggmannia chapadensis sp. nov. is described and illustrated based on characters of the larva, pupa and adults of both sexes, from specimens collected in Cerrado areas of Parque Nacional da Chapada dos Guimarães, state of Mato Grosso, Brazil. The new species is characterized by tarsal claws bent at distal 1/3; well-developed empodia, not reaching the bend in claws; cerci rounded; hipoproct shorter than cerci; aedeagus with globose apex; gonostylus semicircular; ovipositor protrusible about 1.4 times longer than sternite 7; pupal antennal bases enlarged, conical, upper facial horns semicircular; prothoracic spiracle short, abdominal segments 2-8 with one row of dorsal spines; larval terminal segment elongate, with four setose terminal papillae. This new species was collected from lenticular leaf galls of Guapira pernambucensis (Casar.) Lundell (Nyctaginaceae). This is the first record of Bruggmannia galls on this plant species. In Brazil, 13 species of Bruggmannia were previously known, none recorded from Mato Grosso.(AU)

ABSTRACT A new genus and species of gall midge, Haplopappusmyia gregaria, is described and illustrated (larva, pupa, male, and female). This species induces apical galls on Haplopappus foliosus (Asteraceae), an endemic shrub from central Chile. The specimens were collected at La Ligua Municipality, Petorca Province, Valparaiso region, Chile, during spring of 2011-2014. This area corresponds to one of the fifth Mediterranean Matorral biome, considered among Earth's biodiversity hotspots. The new genus is characterized by presenting lateral margin of antennal scape with a mesal reentrance; four-segmented palpus, one-toothed tarsal claws, R5 straight, reaching C anterior to wing apex; male seventh and eighth tergites lacking sclerotization mesally, beyond proximal margin; presence of trichoid sensilla on the abdominal terga and sterna of both sexes, protrusible ovipositor with elongate fused cerci, and larva with 4 pairs of setose terminal papillae.

Interactions between natural enemies and herbivores may be affected by application of fertilizers and different cultivars. We investigated the functional response of the predatory gall midge, Aphidoletes aphidimyza Rondani (Diptera: Cecidomyiidae) larvae to the nymphs of the melon aphid, Aphis gossypii Glover (Hemiptera: Aphididae), reared on two commonly grown cucumber cultivars in Iran (Khasib and Karim) treated with different vermicompost/soil ratios (0:100, 10:90, 20:80, and 30:70%). Based on logistic regression analysis, A. aphidimyza revealed a type II functional response to the aphid in all treatments. Attack rates and handling times of A. aphidimyza larvae on different vermicompost/soil ratios ranged from 0.076 to 0.140 h(-1) and 0.969 to 1.164 h on Khasib and from 0.092 to 0.123 h(-1) and 0.905 to 1.229 h on Karim, respectively. Furthermore, increasing the density of the melon aphid on both cultivars amended with vermicompost/soil ratios resulted in increased prey consumption by the predator. Density of trichomes increased when plants received higher concentrations of vermicompost. So, trichomes may be responsible for different attack rates and handling times of A. aphidimyza on both cultivars.
