Morphology and biology of Porphyrosela minuta Clarke 1953 (Lepidoptera: Gracillariidae, Lithocolletinae) in Uruguay

Abstract

Morfología y Biología de Porphyrosela minuta Clarke 1953 (Lepidoptera: Gracillariidae, Lithocolletinae) en Uruguay RESUMEN -Porphyrosela minuta Clarke es un gracilárido que causa daños sobre trébol blanco (Trifolium repens) en Uruguay. En este artículo, son descriptos huevo, todos los instares larvarios y pupa. Características morfológicas externas del adulto son igualmente incluidas. Se aporta información sobre la biología en condiciones de laboratorio y campo. Los huevos son depositados simples sobre la epidermis superior de los foliolos. Las larvas forman grandes minas a modo de manchas blancas. La larva pasa por cinco estadios sin permanecer expuesta durante su desarrollo. A 25ºC el ciclo de vida requirió de 16,2 días en completarse, correspondiendo 3,0 a huevos, 8,8 a larva y 4,4 a pupa. Las hembras iniciaron la puesta la primera noche y durante un periodo de oviposición que osciló entre cinco y 12 días depositaron en promedio 71,8 huevos. Es una especie multivoltina que desarrolla de siete a nueve generaciones de noviembre a fines de marzo. PALABRAS-CLAVE: Insecta, minador de hojas, descripción, desarrollo, reproducciónABSTRACT -Porphyrosela minuta Clarke is a gracillariid that causes damage on white clover (Trifolium repens) in Uruguay. In this article, the eggs, all the larval instars, the pupa and the external morphological characteristics of the adult are described. Information about the insect's biology under laboratory and field conditions is presented. The eggs are laid singly on the upper surface of the leaflets. The larvae make extensive mines that appear as white blotches. The larvae develop through five instars and do not remain exposed during their development. At 25ºC the life cycle lasted 16.2 days, made up of 3.0 for eggs, 8.8 for larvae and 4.4 for pupae. Females began laying on the first night, and during an oviposition period that varied between five and 12 days deposited an average of 71.8 eggs. It is a multivoltine species and seven to nine generations occur between November and the end of March.

Egg laying site selection by a host plant specialist leaf miner moth at two intra-plant levels in the northern Chilean Atacama Desert

“…2A). Egg laying patterns among leaf or leaflet surfaces have been already described for some other Neotropical species of Gracillariidae (Davis 1994;Mundaca 2005;Bentancourt & Scatoni 2007;Kawahara et al 2009;Davis & De Prins 2011;Davis & Wagner 2005, 2011Brito et al 2012Brito et al , 2013Mundaca et al 2013). In terms of the leaf mine, observations indicate that most of the Gracillariidae larvae begin mining the leaf on the same surface where the egg has been deposited, as previously described for A. tecomae Vargas 2010).…”

Systematics, phylogeny and biology of a new genus of Lithocolletinae (Lepidoptera: Gracillariidae) associated with Cistaceae

“…Pupa without cremaster in Triberta and remaining eight lithocolletine genera, except in Phyllonorycter and Porphyrosela. The cremaster is well-defined in Phyllonorycter and reduced, consisting of four little hooks, in Porphyrosela (Bentancourt & Scatoni 2007). A thickened sclerotized ridge present along the lateral sides of pupal A1-8, in Triberta, which differentiates the new genus from Phyllonorycter and Cameraria.…”

First Report ofNeosilba pradoiandDasiops frieseni(Diptera: Lonchaeidae) in Cultivated and Wild Hosts in Uruguay

“…María Victoria Calvo 1* , Soledad Delgado 1 , Iris Scatoni 1 , and Flavio Roberto Mello Garcia 2 The members of the family Lonchaeidae (lance flies) are glossy black color with a blue or green metallic shine, or a mixture of both blue and green. The larvae usually are saprophagus or frugivorous (Bentancourt et al 2009). This family is very well represented in South America, although knowledge of the frugivorous Lonchaeidae is just being developed; presently, little or nothing is known about the identity and biology of the many South American species (Korytkoioski & Ojeda 1971;Norrbom & McAlpine 1997;Strikis et al 2011;Gisloti et al 2017).…”
