The pest risk analysis (PRA) was carried out for Sosnowsky’s hogweed to determine the ability of the species to be a quarantine object by analyzing the available scientific data. According to the results of the PRA, Sosnowsky’s hogweed can be classified as a regulated weed and socially dangerous to human and animal health, highly aggressive in spread, and extremely difficult to eradicate in many areas, where it is widespread in small numbers. It allows to apply measures to it as for any quarantine plant: to control its appearance and completely eradicate it’s entry source. The results of developed method have been proposed using the example of town Chernivtsi. Weed density have decreased from 47,8 and 43,5 plants to 4,8 and 1,2 plants on 1 m2 in a number of hotbeds. These measures allowed to decrease the quantity of Sosnovsky’s hogweed in some hotbeds by more than 25 times.

AbstractIn this article, we investigate how pest risk management protocols may affect trade flows of fresh apples. We apply our analysis to two major players in the international trade of fresh apples: France and Chile. These two countries have been chosen because they are among the world’s leading apple exporters and although they have similar market shares, they differ in terms of destination markets, seasonality, local conditions and export strategy. In order to assess the impact of pest risk management protocols on international trade of apples from France and Chile, we introduce in a gravity equation beside the traditional variables, a score able to measure their complexity. The results are interesting in the sense that even if the score for France and Chile by main trading partners are rather close, we found that French apples exporters would be more impacted by pest risk management protocols than their Chilean counterparts.

AbstractPest risk assessment is typically performed by expert taxonomists using a pest’s biological data. However, the biological data or expert taxonomists may be difficult to find. Here, we used species distribution modelling to predict potential invasion in which phytophagous quarantine pests survive in Taiwan; the pests (unrecorded yet in Taiwan) included were three notorious quarantine whiteflies (Crenidorsum aroidephagus, Aleurothrixus trachoides, and Paraleyrodes minei) and three aphids (Nasonovia ribisnigri, Macrosiphum euphorbiae, and Viteus vitifoliae). In brief, maximum entropy modelling (MaxEnt) was used to predict the suitability of the pests’ habitats under certain climatic conditions, and then receiver operating characteristic curve analysis was performed (to verify the prediction result). We then analysed environmental variables affecting the habitat suitability and matched them with Taiwan’s crop cultivation areas for the assessment of potential invasion. We observed that the habitat suitability of the cultivation areas of host plants was low for C. aroidephagus, A. trachoides, and N. ribisnigri but was high for the remaining three species. Moreover, precipitation of coldest quarter negatively affected habitat suitability for C. aroidephagus, P. minei, N. ribisnigri, and M. euphorbiae. Seasonal temperature changes also negatively affected the habitat suitability for A. trachoides. This is the first study to demonstrate the use of species distribution modelling as the preliminary step for the pest risk assessment of these emerging pests with limited biological data before their invasion.

Abstract E. pyramidalis, a perennial grass, has decidedly invasive characteristics with its vigorous shoot and rhizome growth and abundant seed production. As an aquatic, it also has the potential to be very damaging to sensitive aquatic habitats. Holm et al. (1979) record it as a major weed in its native area in Nigeria, Swaziland, Sudan and Madagascar. In Guyana, after being introduced and cultivated for some years, it was noticed as a weed in sugar cane in 1982 and increased rapidly to become one of the most troublesome weeds in the aquatic system of the Guyana Sugar Corporation (Bishundial et al., 1997). In Mexico, again after introduction as a fodder grass, it has become widely invasive in wetlands, tending to reduce native wetland species (López Rosas et al., 2010). Apart from its competitive growth, Wells et al. (1986) note its tendency to obstruct water flow. For the USA it is highly ranked as a potential invasive weed of the future (Parker et al., 2007) and it has been identified as a species 'not authorized (for introduction) pending pest risk analysis' (NAPPRA) (USDA-APHIS, 2012).

In keeping with the directive in Executive Order 13874 (Modernizing the Regulatory Framework for Agricultural Biotechnology Products) to adopt regulatory approaches that are proportionate to risk and avoid arbitrary distinctions across like products, the US Department of Agriculture (USDA) revised its biotechnology regulations by promulgating the Sustainable, Ecological, Consistent, Uniform, Responsible, and Efficient (SECURE) rule. Specifically, the SECURE rule 1) establishes exemptions for plants modified by genetic engineering where the modification could otherwise have been made through conventional breeding, 2) uses risk posed by the introduced trait to determine whether an organism is regulated, rather than relying on whether the organism was developed using a plant pest, and 3) provides a mechanism for a rapid initial review to efficiently distinguish plants developed using genetic engineering that do not pose plausible pathways to increased plant pest risk from those that do. As a result of the focused oversight on potentially riskier crops developed using genetic engineering, USDA is expected to improve the efficiency and effectiveness of its oversight program. The reduced regulatory burden is expected to promote innovation by expanding the number and diversity of developers to include smaller businesses and academics and to increase the number and variety of traits being developed through biotechnology.

The article reviews the concept and technology of pest risk assessment for the spread of quarantine species based on ecological and geographical analysis and ecological niche modeling. Using a quarantine species Ipomoea hederacea (L.) Jacq. as an example, we calculated the ecological requirements of the species. The main ecological factors limiting the spread of I. hederacea were determined and the ecological amplitudes of the species in relation to each factor limiting its distribution were quantitatively estimated. We identified ecologically suitable habitats and compiled a map of the ecological-geographical niche of the species using specially created environmental maps based on the obtained data of the ecological limits of the species. Using the map of the ecological-geographical niche, the I. hederacea distribution risk in the regions of the Russian Federation was estimated. Similar maps can be used for basis of quantitative as well as targeted risk assessment of penetration and establishment of harmful organisms. Obtained information will be useful to compile lists of quarantine species, estimate the potential areas of geographic distribution of pests into Russian Federation, and make decisions for introduction of effective phytosanitary measures to prevent the penetration of these invasive organisms. It can also be used as the basis for organizing and conducting phytosanitary monitoring in the Russian Federation.
