“…Research interest in cyclocephaline immature stages has recently increased, with approximately 80% of larval and pupal descriptions published after 1990 (Morelli 1991, Morelli and Alzugaray 1994, Vincini et al 2000, Ramírez-Salinas et al 2004, Vallejo and Morón 2008, Neita-Moreno and Morón 2008, Bran et al 2006, Neita-Moreno et al 2007, Vallejo and Morón 2008, Neita-Moreno and Morón 2008, Lugo-García et al 2009, Stechauner-Rohringer and Pardo-Locarno 2010, Neita-Moreno and Yepes 2011, Albuquerque et al 2014, Souza et al 2014a, b, Morón et al 2014). It is not yet possible to characterize cyclocephaline larvae or pupae at the tribal level as only 4 of 14 genera have described immatures (Table 5 and Table 6).…”

The cyclocephaline scarabs (Scarabaeidae: Dynastinae: Cyclocephalini) are a speciose tribe of beetles that include species that are ecologically and economically important as pollinators and pests of agriculture and turf. We provide an overview and synopsis of the 14 genera of Cyclocephalini that includes information on: 1) the taxonomic and nomenclatural history of the group; 2) diagnosis and identification of immature life-stages; 3) economic importance in agroecosystems; 4) natural enemies of these beetles; 5) use as food by humans; 6) the importance of adults as pollination mutualists; 7) fossil cyclocephalines and the evolution of the group; 8) generic-level identification of adults. We provide an expanded identification key to genera of world Cyclocephalini and diagnoses for each genus. Character illustrations and generic-level distribution maps are provided along with discussions on the relationships of the tribe’s genera.

“…Larvae are described for four Ancognatha species (Ritcher 1966, Ramírez-Salinas et al 2004, Vallejo and Morón 2008, Neita-Moreno and Morón 2008). South American larval descriptions are largely based on material collected in agroecosystems, and thus the natural ecology of Ancognatha immatures is poorly known.…”

Descriptions, diagnoses, locality and temporal records, distributional maps, and illustrations of the 11 species of Ancognatha Erichson occurring in Ecuador are provided. Four new country records are reported for Ecuador, and a new species is described. A female lectotype at the Natural History Museum (London) for Ancognatha jamesoni Murray is designated. A key to the Ecuadorian species is included. RESUMENSe proporcionan descripciones, diagnosis, localidades y meses de colecta, mapas de distribución e ilustraciones de las 11 especies de Ancognatha Erichson que se encuentran en Ecuador. Se reportan cuatro registros nuevos para el país y se describe una especie nueva. Se designa el lectotipo hembra de Ancognatha jamesoni Murray del Natural History Museum (Londres). Se incluye una clave para las especies ecuatorianas.

“…The second approach consisted in the manual capture or through the use of entomological nets of individuals in plots with high levels of insect damage and/or populations on affected structures. These individuals were placed in jars with a 70% alcohol-sterile distilled water solution (v:v) and transported to the MELG for identification at the genus level using taxonomic keys [30,[34][35][36][37][38][39][40].…”

Causes of Hass Avocado Fruit Rejection in Preharvest, Harvest, and Packinghouse: Economic Losses and Associated Variables

2019

The areas planted with avocado in Colombia have increased to position this fruit in international markets. To achieve this goal, the offered fruits need to meet optimal production standards. The aim of this study was to identify the main physiopathologies and damages that may cause the rejection of avocado cv. Hass fruits for export purposes during pre-harvest, harvest, and processing in packinghouses, and quantify the economic impact of said exclusion criteria. Typological characterization and quantification of damages that may cause fruit rejection were performed at the laboratory, field, and packinghouses. Data were obtained from 136 Colombian productive plots with monitoring and data collection records for a minimum of five years. At the packinghouse level, data associated with factors that affect quality (both, those identified at packing plants and those detected in simulated shipments) were considered. The main causes of fruit rejection during pre-harvest and harvest were: low calibers, damage to the epidermis by insect pests from the subfamily Melolonthidae, thrips, mites, the bug Monalonion, overripe fruits, and sunburn damage. In addition, pathologies such as anthracnose and stem end rot, and problems associated with browning of vascular bundles, irregular ripening, chilling injury, and lenticel damage were highly limiting at packinghouses. The economic analysis identified losses of 5.78 and 5.68% in farms and packinghouses, respectively, which are equivalent to US dollar (USD) 80.29 per produced ton. This work generated information that allows prioritizing strategies to improve fruit quality and reduce economic impact.
