Bio-inspired computation: where we stand and what's next

In recent years, the research community has witnessed an explosion of literature dealing with the adaptation of behavioral patterns and social phenomena observed in nature towards efficiently solving complex computational tasks. This trend has been especially dramatic in what relates to optimization problems, mainly due to the unprecedented complexity of problem instances, arising from a diverse spectrum of domains such as transportation, logistics, energy, climate, social networks, health and industry 4.0, among many others. Notwithstanding this upsurge of activity, research in this vibrant topic should be steered towards certain areas that, despite their eventual value and impact on the field of bio-inspired computation, still remain insufficiently explored to date. The main purpose of this paper is to outline the state of the art and to identify open challenges concerning the most relevant areas within bio-inspired optimization. An analysis and discussion are also carried out over the general trajectory followed in recent years by the community working in this field, thereby highlighting the need for reaching a consensus and joining forces towards achieving valuable insights into the understanding of this family of optimization techniques

Fluctuación poblacional de Anastrepha ludens en la región de Santa Engracia, Tamaulipas, México

The Mexican fruit fly Anastrepha ludens (Loew) is a pest of great impact on citrus in Tamaulipas. Attacks host of commercial importance such as oranges, grapefruit and tangerines, restricting their business mobility to national or international markets. In this study from population fluctuation during the years 2008-2011 of A. ludens in Santa Engracia area, three periods based on presence ofthe insect and its relationship with average temperatures were determined: January-April, May-August and September to December. Descriptive statistics highlighted the variability between observations, suggesting heterogeneity in insect densities. The MTD (fly / trap x day) average weekly was associated with different climatic variables through a linear and multiple regression analysis observing weak correlations in general due to the variation of MTD average. The minimum temperature variable was the most consistent and with higher fitting. The minimum and maximum temperature in multiple regressions represented the explanatory variables for each year, while precipitation did not show a clear association with MTD average, perhaps for irrigation activities within commercial areas or an outdated influence. A close association between phenology of commercial fruits and population fluctuation was observed. The results of this study have practical implications for decision making in integrated pest management with an approach to large areas.La mosca mexicana de la fruta Anastrepha ludens (Loew), es una de las plagas de mayor impacto en la citricultura en Tamaulipas. Ataca hospederos de importancia comercial como la naranja, toronja y mandarinas restringiendo su movilidad comercial a mercados nacionales o internacionales. En este estudio a partir de la fluctuación poblacional durante los años 2008 a 2011 de A. ludens en el área de Santa Engracia se determinaron tres periodos con base a la presencia del insecto y su relación con la temperatura promedio: enero-abril, mayo-agosto y septiembre-diciembre. La estadística descriptiva destacó la variabilidad entre las observaciones, sugiriendo una heterogeneidad en las densidades del insecto. El MTD (mosca/trampa x día) promedio semanal se relacionó con diferentes variables climáticas mediante un análisis de regresión lineal y múltiple, observándose correlaciones débiles en general debido a la variación del MTD promedio. La temperatura mínima fue la variable más consistente y con mayor ajuste. La temperatura mínima y máxima en la regresión múltiple representaron las variables explicatorias para cada año, mientras que la precipitación no presentó una asociación clara con el MTD promedio quizás por actividades de riego dentro de las áreas comerciales o por una influencia desfasada. Se observó una asociación cercana entre la fenología de los frutos comerciales y la fluctuación poblacional. Los resultados de este estudio tienen implicaciones prácticas para la toma de decisiones en el manejo integrado de esta plaga con enfoque de áreas grandes

Crisomélidos asociados a recursos forestales maderables y no-maderables en Victoria, Tamaulipas

Among the most economically important insect herbivores are Chrysomelidae, who are also bacteria vectors and phytopathogenic viruses. In Tamaulipas, 610 species of useful plants are listed, of which 30% are edible. Ecological processes such as herbivory caused by insect reduce the quality, quantity and price of plant products (leaves, stems, roots, flowers, fruits, seeds) which are fully or partially damaged. In the present study monthly collections were made directly and with insect net for a year from February 2012 to January 2013 in the localities of Cañon La Libertad and Cañon del Novillo, located in the municipality of Victoria, Tamaulipas. The biological material was mainly collected from plant species of economic importance, transported to the laboratory of entomology at the IEA-UAT for taxonomic determination. 26 species of Chrysomelidae belonging to 24 genera were determined. Keywords: Coleoptera; host plants; pestsEntre los herbívoros de la clase Insecta más importantes económicamente, se encuentran los crisomélidos, quienes además son vectores de bacterias y virus fitopatógenos. En Tamaulipas, se listan 610 especies de plantas útiles, de las cuales 30% son comestibles. Procesos ecológicos como la herbivoría causada por insectos reducen la calidad, cantidad y precio de los productos vegetales (hojas, tallos, raíces, flores, frutos, semillas) que son dañados total o parcialmente. En el presente estudio se realizaron colectas mensuales de manera directa y con red de golpeo durante un año a partir de febrero 2012 a enero 2013, en las localidades del Cañón La Libertad y el Cañón del Novillo, localizadas en el municipio de Victoria, Tamaulipas. El material biológico se colectó principalmente de especies vegetales de importancia económica, se transportó al laboratorio de entomología del IEA-UAT para su determinación taxonómica.

Diversidad de la flora de interés apícola en el estado de Tamaulipas, México

Apiculture continues to grow steadily in Mexico as does interest in potential nectariferous and polliniferous flora in different states. An inventory was made of melliferous plant species in the state of Tamaulipas, Mexico, visited by Apis mellifera L. in different annual seasons. Field work was done between 2012 and 2015. Plant species whose flowers were visited by A. mellifera were documented, including data on life form, growth form, origin, resource production, vegetation type and flowering time. A total of 215 species were recorded belonging to 173 genera and 60 families of phanerogamic plants. Most are native species (87.91 %) and herbaceous (42.32 %). Fabaceae and Asteraceae are the most common families. The highest proportion of plants are nectariferous (45.12 %), followed by nectariferous-polliniferous (40 %) and polliniferous (14.88 %). Secondary vegetation and dry tropical forest contain the largest number of these species, and provide the greatest floral resources during the summer season.El desarrollo de la apicultura en México ha incrementado el interés por conocer el potencial de la flora nectarífera y polinífera en diferentes estados.
