“…Parasitoids are more specific than other biological control agents and therefore have restricted host ranges, which is an advantage to implement biological control programs ( VanLenteren & Manzaroli, 1999). The finding and taxonomic identification of Synopeas species in the present study open a new opportunity to explore their potential to be used in IPM programs in order to reduce the high input of pesticides against P. longifila in the tropics (Valarezo et al, 2003;Kroschel et al, 2012). It is unknown if P. longifila or P. floricola cause economic damage to Tahiti lime orchards in Colombia (Hernandez et al, 2015;Duque-Gamboa, 2017) and if that is the case, the results of the present study indicate that Synopeas aff.…”

“…The bud midge Prodiplosis longifila Gagné (Diptera: Cecidomyiidae) is a severe pest mainly of Solanaceae crops in South America, causing economic losses in potato (Solanum tuberosum L.) in Peru (Kroschel, Mujica, Alcazar, Canedo & Zegarra, 2012) and tomato (Solanum lycopersicum L.) in Ecuador (Valarezo, Cañarte, Arias, Proaño, Navarrete, Garzón, Jines, Cuadros, Porro, Linzán & Chávez, 2003) and Colombia (Hernández et al, 2015). Besides Solanaceae crops, P. longifila causes losses to asparagus (Asparagus officinalis L.) (Asparagaceae) crops in Peru (Goldsmith, Castillo & Clarke-Harris, 2013) and to flower buds of Tahiti lime (Citrus x latifolia Tanaka ex Q. Jiménez) (Rutaceae) orchards in the United States (Florida) (Peña, Duncan & Torres, 1990).…”

“…longifila larvae feed on leaf buds, flowers and immature tomato fruits and on flowers and flower buds of Tahiti lime (Peña, Duncan & Torres, 1990;Hernandez et al, 2015) and consumes the epidermis tissue of asparagus shoots (Goldsmith, Castillo & Clarke-Harris, 2013). Control of P. longifila on different crops include adult mass trapping using light and color traps (Goldsmith, Castillo & Clarke-Harris, 2013), physical control with high pressure water to remove adults (Goldsmith, Castillo & Clarke-Harris, 2013) but chemical spray is the principal control method used (Valarezo et al, 2003;Kroschel et al, 2012). In relation to biological control several natural predators have been reported (Valarezo et al, 2003;Goldsmith, Castillo & Clarke-Harris, 2013).…”

Several species of Synopeas Förster (Hymenoptera: Platygasteridae) are parasitoids of gall midges and bud (Diptera: Cecidomyiidae) worldwide. In Neotropical region, the bud Prodiplosis longifila Gagné causes severe economic losses, particularly in tomato (Solanum lycopersicum L.) crops. Prodiplosis longifila is found in North and South America, and it is a potentially invasive species that is also found throughout Caribbean Islands. To diminish the impact of P. longifila on crops and to delay its geographical expansion it is necessary to identify its natural enemies and to improve its biological control. As a first step in this direction, in this study, four species of Synopeas: S. aff. curvicauda, S. aff. longiventre, S. reticulatifrons and S. varipes were collected from Prodiplosis longifila, Prodiplosis floricola and Dasineura sp. larvae sampled on Solanaceae crops (Solanum lycopersicum, Capsicum annuum and C. frutescens) and Tahiti lime (Citrus x latifolia) in Colombia. Parasitoid species were identified based on morphological characteristics. Results indicate that Synopeas species can parasitize species of both Prodiplosis Felt and Dasineura Rondani genera and they are potential biological control agents to integrate into pest managements strategies against P. longifila.

“…In Peru it attacks more than fifteen horticultural crops (Diaz-Silva, 2011) including asparagus, tomato, potato, bean and cucurbits (Diaz-Silva, 2011;Goldsmith et al, 2013;Kroschel et al, 2012). In Ecuador P. longifila also attacks several horticultural crops as tomato, potato, soybean, bean, bell pepper (Valarezo et al, 2003).…”

Se llevaron a cabo estudios de laboratorio para determinar parámetros de historia de vida del mosquito de las agallas Prodiplosis longifila, una plaga clave del tomate. Huevos de P. longifila colectados en cultivos de tomate eclosionaron, en promedio, en 1,2 días y el tiempo de desarrollo (larva I hasta adulto) fue alrededor de 14 días a condiciones ambientales. La proporción de sexos (macho: hembra) de P. longifila fue de 1:1.03. La longevidad promedia del macho y de la hembra (1,1 días ambas) se incrementaron después de consumir azúcar. Ensayos de campo para determinar la fluctuación poblacional de P. longifila se desarrollaron en tres lotes comerciales de tomate en Colombia bajo aspersiones de insecticidas tipo calendario. Los números promedio de larvas en todos los lotes fueron mayores durante las dos últimas semanas que durante las dos primeras semanas de muestreo. El número de larvas aumentó aún bajo la aspersión de insecticidas. El número de larvas aumentó después de la floración, sugiriendo que los adultos fueron atraídos a las flores de tomate y probablemente las utilizaron como fuente de azúcar. La infestación (%) estuvo correlacionada positivamente con el número promedio de larvas/brote foliar, sugiriendo el potencial de este método indirecto para monitorear larvas de P. longifila en tomate. La aspersión de insecticidas en cultivos de tomate para controlar P. longifila en un esquema basado en el calendario no redujo la densidad de larvas.

“…Sustainable intensification, it is argued, can extend the carrying capacity of the land to meet human food security needs [41][42][43]. In Andean agricultural systems, intensification options include the promotion of new varieties, crop biodiversity, homegardens or better practices for soil fertility, handling pests and disease, and storage of target crops, among others [44][45][46][47][48][49][50][51]. The desired outcome of such efforts is to increase the household-level food and nutrient quantity (yield) and quality (diversity, micronutrient density) under current landholding sizes.…”

The challenge of achieving basal energy, iron and zinc provision for home consumption through family farming in the Andes: a comparison of coverage through contemporary production systems and selected agricultural interventions

Background: Child undernutrition is persistently high in the central Andes of Peru, and numerous smallholder households fail to meet their basic needs of energy, iron and zinc. Food-based approaches assume household-level nutrition can be improved following agricultural interventions. This study assesses for the first time whether current Andean production systems provide sufficient energy, iron and zinc output to meet household-level requirements and explores the likely effect of commonly promoted food-based approaches. Across four communities, we determined the crop and livestock production output for each household (n = 165) during one growing season. The household-level nutritional demand or input was calculated as a function of household composition and daily requirements of energy, iron and zinc as established by FAO/WHO. We examined five scenarios, current practice or status quo and four food-based interventions: (1) increased potato yield, (2) introduced biofortified potatoes, (3) promotion of guinea pigs and (4) a mixed strategy combining all of the above. Results:Under status quo, 86, 62 and 76 % of households obtained sufficient production output to meet energy, iron and zinc requirements, respectively. Considering the three parameters simultaneously, 59 % of households were able to meet their energy, iron and zinc requirements. The total crop production among households provided more than the necessary energy, iron and zinc output to meet the demand of all 165 households. Yet, significant differences between households account for individual deficits or surpluses in household-level output-input balances. Potato (Solanum spp.), barley (Hordeum vulgare) and faba (Vicia faba) production was particularly significant in determining the energy, iron and zinc output. Livestock did not make a substantial contribution. The main difference between households with negative versus positive coverage, in terms of household-level production output from agriculture meeting demand (=input), was available cropping area given household size. None of the explored food-based interventions closed the energy, iron and zinc deficit from production among households with negative coverage. Conclusions:The smallholder production systems analyzed are only partially capable of providing sufficient production output to cover household-level energy, iron and zinc demands. Of the four interventions examined, a mixed
