“…With this precondition, let us introduce the physiologically based model applied to describe D. suzukii populations developing over time t and through the life stages x. The population density function, hence, is represented by a two-variables function N(t, x), solution of the following first-order partial differential equation [25,26,28]:…”

“…Accordingly, there is no possibility of calculating analytical solutions for the Equation 1, and it makes necessary the use of numerical solutions, in order to increase the precision of the simulations. A numerical scheme was proposed by Rossini et al [25] in their first formulation of the model, and it provides for a combined use of the upwind scheme and Euler's finite difference method [32]. More specifically, this methodology consists of a backward approximation of the partial derivative on the age variable, and a forward approximation of the partial derivative on time variable, providing the following scheme:…”

“…This study aims to apply and validate the physiologically based model introduced by Rossini et al [25,26] in the case of D. suzukii. In particular, this model describes populations of ectotherms which develop over time and through their life stages, including biological information and environmental factors.…”

The Spotted Wing Drosophila (SWD), Drosophila suzukii (Matsumura), is a harmful insect pest for soft fruit cultivations. Even though its main hosts belong to the genera Prunus and Rubus, its high polyphagy and adaptability to new environments makes it a serious problem for farmers worldwide, who have reported several economic losses because of this pest. A wide series of proposals to control SWD are available and operate in line with the mechanisms of integrated pest management, demonstrating their high efficiency when applied at the opportune moment. This work aims to apply and validate a physiologically based model which summarises all the available information about D. suzukii biology, such as the relationship between environmental temperature and its development, fertility and mortality rates. The model provided, as a result, a description of a population of SWD females taking into consideration the multiple generations that occurred during the year. Simulations were then compared with field data collected in a three-year survey in two experimental fields located in the Sabina Romana area (Lazio, Italy). More specifically, D. suzukii males were monitored with traps in fields cultivated with mixed varieties of cherries and they were selected because of their clearer identification in comparison to females. Results showed a high level of reliability of simulations in representing the field data, highlighting at the same time that there is no discrepancy in simulating D. suzukii females in order to represent male populations.

El tomate es cultivado en todos los continentes y representa una de las principales fuentes de vitaminas y minerales, lo cual lo hace muy apetecido en el consumo diario de los hogares. Ante el resurgimiento de nuevas plagas en el cultivo de tomate los productores aplican indiscriminadamente plaguicidas, provocando efectos negativos para el ambiente y la salud humana. El objetivo fue diagnosticar el uso e impactos de plaguicidas en el cultivo de tomate en la parroquia Riochico, cantón Portoviejo, provincia de Manabí, Ecuador. Se utilizó el método deductivo e inductivo, sobre los agricultores dedicados a la actividad tomatera, lo cual permitió diagnosticar, describir y determinar el impacto en la sostenibilidad agroecológica por el uso indiscriminado de plaguicidas. Los resultados mostraron que las aplicaciones de plaguicidas se las realiza sin criterio técnico y se sitúan entre 35 a 40 aplicaciones durante el ciclo de este cultivo y lo aplican hasta <de 8 días antes de colocar el tomate en el mercado. Los agricultores de este sector aplican incorrectamente insecticidas a dosis superiores a las recomendadas, afectando a la salud humana y al ambiente, además, algunos aplican plaguicidas por sugerencias de otro agricultor, lo cual incide en el uso y manejo de agroquímicos, sin criterio técnico. Es necesario que el gobierno ecuatoriano implemente medidas a fin de preservar la salud de los productores y consumidores.

Biological invasion risk assessment of Tuta absoluta: mechanistic versus correlative methods

et al. 2021

The capacity to assess invasion risk from potential crop pests before invasion of new regions globally would be invaluable, but this requires the ability to predict accurately their potential geographic range and relative abundance in novel areas. This may be unachievable using de facto standard correlative methods as shown for the South American tomato pinworm Tuta absoluta, a serious insect pest of tomato native to South America. Its global invasive potential was not identified until after rapid invasion of Europe, followed by Africa and parts of Asia where it has become a major food security problem on solanaceous crops. Early prospective assessment of its potential range is possible using physiologically based demographic modeling that would have identified knowledge gaps in T. absoluta biology at low temperatures. Physiologically based demographic models (PBDMs) realistically capture the weather-driven biology in a mechanistic way allowing evaluation of invasive risk in novel areas and climes including climate change. PBDMs explain the biological bases for the geographic distribution, are generally applicable to species of any taxa, are not limited to terrestrial ecosystems, and hence can be extended to support ecological risk modeling in aquatic ecosystems. PBDMs address a lack of unified general methods for assessing and managing invasive species that has limited invasion biology from becoming a more predictive science.
