“…Further, inefficient biochemical pathways in such plants lead to an accumulation of simple sugars, free amino acids and peptides, providing an enriched diet for arthropod herbivores. In laboratory experiments, any deleterious effects of enriching soil on herbivorous insects were at least partially plant-mediated [48,49]. Consistent with the mineral balance hypothesis, the mineral content of plant leaves explained 40-57% of the variation in Colorado potato beetle populations observed in field plots [48].…”

Two desirable functions of healthy soil are nutrient cycling and pest suppression. We review relevant literature on the contributions of soil microarthropods to soil health through their intersecting roles in decomposition and nutrient cycling and direct and indirect suppression of plant pests. Microarthropods can impact soil and plant health directly by feeding on pest organisms or serving as alternate prey for larger predatory arthropods. Indirectly, microarthropods mediate the ability of crop plants to resist or tolerate insect pests and diseases by triggering induced resistance and/or contributing to optimal nutritional balance of plants. Soil fauna, including microarthropods, are key regulators of decomposition at local scales but their role at larger scales is unresolved. Future research priorities include incorporating multi-channel omnivory into food web modeling and understanding the vulnerability of soil carbon through global climate change models.

“…Plants grown in manureamended soil were inferior CPB hosts compared with plants grown in synthetically fertilized soil (Alyokhin & Atlihan 2005). In the current trial, the beetles originated from potato plots were differently treated.…”

“…Negative impacts of freeze-thaw cycles occur if high temperatures lead to a reduction or loss of winter snow cover, and the soil frost deepens (Groffman et al 2001). We have made observations on CPB cold hardiness and overwintering during two periods, 2001-2005(Hiiesaar et al 2006. Only once, in 2002/2003, was the survival of beetles endangered by extremely low temperature when the soil temperature decreased to −7°C for a longer period; all the beetles overwintering in clay soil perished, whereas of those in loamy sand with better aeration 12% survived (Hiiesaar et al 2006).…”

Before its establishment in Estonia at the beginning of the twenty-first century, the Colorado potato beetle Leptinotarsa decemlineata Say was a notifiable quarantine pest for many years. In high-latitude environments it encounters strong evolutionary pressure to adapt to low temperatures due to high overwintering mortality and periodic influx of new individuals from more southern populations. Our study focused on gathering evidence for such a range shift leading to the formation of a permanent local population. The phenology and overwintering success of beetles was investigated from 2008 to 2015. Depending on weather conditions in the different years, the overwintered beetles emerged from the soil from the beginning of May to mid-June. Over 700 degree days accumulated in 2010, 2011, 2013 and 2014 exceeding the limit needed for development of two generations. However, food supply and temperature distribution in the growing period enabled development of the second complete generation only in 2010 and 2013. Survival of overwintering beetles in field conditions varied between 18% and 47% in the different years. Winter mortality was not associated with low air temperature in any year as snow cover provided the necessary protection and winter soil temperatures at the depth of 30 cm remained at around 0°C for the duration of the whole observation period, with only some records as low as −3.5°C. The survival of overwintering beetles is more likely defined by factors other than low temperature. As a result of periodic invasions of beetles with naturally lower cold resistance originating from southern regions, the structure of the overwintering population in Nordic temperate conditions is not homogeneous. Moreover, this may also be derived from cultural practices, as commercial producers regularly apply agrochemicals while organic growers avoid them. ARTICLE HISTORY

“…In a comparison of organic and mineral fertilizers in soils with a short history of organic production, Boiteau et al (2008b) observed a shift in the timing of peak populations of Colorado potato beetles but no significant change in abundance. Alyokhin and Atlihan (2005) and offered partial support for the hypothesis on potato by showing that populations of Colorado potato beetle on manure amended potato plots were lower and took longer to develop than on chemically fertilized plots. The level of plant resistance to insect pests that could be expected from healthy soils remains poorly known but the available evidence suggests a relationship with a prolonged history of organic soil management practices.…”

The development of insect pest management strategies for potato has long been based on the eventual replacement of insecticides by alternative methods. This paper discusses the importance of moving away from this confrontational approach and toward the harmonization of conventional and alternative insect control concepts. A harmonized set of control methods should speed up progress towards a truly integrated management approach that provides both long and short term crop protection. Changing the paradigm does not resolve all the problems. Constraints to the development and implementation of the different types of control methods are discussed using selected examples. The harmonization concept has been discussed in general terms elsewhere but to the best of my knowledge it is applied here for the first time specifically to potato crop protection.Resumen El desarrollo de estrategias de manejo de insectos plaga para papa se ha basado por mucho tiempo en el eventual reemplazo de insecticidas por métodos alternativos. Este artículo discute la importancia de alejarse de este enfoque confrontacional, e ir hacia la armonización de los conceptos convencionales y alternativos del control de insectos. Un conjunto de métodos de control armonizado podría acelerar el progreso hacia un enfoque de manejo integrado verdadero, que proporcione protección al cultivo tanto a largo como a corto plazo. El cambio de paradigmas no resuelve todos los problemas. Se discuten las limitantes para el desarrollo e implementación de los diferentes tipos de métodos de control, usando ejemplos selectos. En términos generales, se ha discutido el concepto de armonización en otros lados, pero hasta donde yo sé, se aplica aquí por primera vez específica-mente para la protección del cultivo de papa.
