This study explored the thermal response of Drosophila suzukii, an injurious insect pest present in many countries worldwide, at different controlled conditions. species is responsible for several economic losses soft fruit cultivations, develops on ripening fruits, and has capability to quickly adapt new territories climates, closing multiple generations per year. Given its high invasive potential increasing need low-impact control strategies, in-depth exploration biology this stage fundamental. Specimens Italian strain from Apulia were reared growth chambers constant temperatures (6, 9, 13, 18, 20, 24, 25, 26, 27, 28, 29, 31, 32 33 °C). The life cycle each specimen was individually tracked egg death adults, considering larval stages distinction as well. Besides development mortality, production over temperature been recorded. dataset first analysed according tables studies; then, we also estimated biological parameters most common equations describing development, fertility involved physiologically-based model applications. results confirmed extended information already literature, but with reference a population adapted warmer climates. successfully developed adult 13-29 °C, while between 6-9 29-33 °C limited L2/L3 stages. Optimal are around 26-28 depending stage. provides one complete overviews D. which available current opens door more accurate modelling frameworks.

Does insect trapping truly measure insect populations?

Agricultural and Forest Entomology, Год журнала: 2025, Номер unknown

Опубликована: Фев. 19, 2025

Abstract The measurement process has a well‐known structure and requires tools with proper characteristics, depending on the physical quantities their magnitude. While most fields of research have reliable to support experiments, this is not properly case for measurements in population dynamics insects animals, more general. Monitoring insect species common practice agriculture forest environments, above all develop pest control or biodiversity conservation strategies validate feed decision system tools. Besides development several monitoring techniques, an explicit connection between entomology metrology (the science measurements) still missing. We may ask if current involved populations, as traps instance, respect standard features that should have, they provide ‘proper measurements’ just ‘estimation’. This work analyses pros cons trapping by connecting provides some perspectives which communities focus interact answer questions open.

A data platform for real-time monitoring and analysis of the brown marmorated stink bug in Northern Italy

Ecological Informatics, Год журнала: 2024, Номер 82, С. 102713 - 102713

Опубликована: Июль 6, 2024

The brown marmorated stink bug (Halyomorpha halys) is one of the main insect pest species causing economic damage to several agricultural commodities worldwide and worst threats tree fruit crops in northern Italy, especially Emilia-Romagna region. Previous efforts implementing H. halys surveillance at regional level were mainly focused on studying phenology, but they not designed provide a public service. In this paper, we propose data-driven approach support application Integrated Pest Management strategies against halys. proposal based experience three-year project which network monitoring traps has been deployed throughout whole region data platform implemented enable real-time tracking occurrence distribution, integrating these information with multiple sources, analytical capabilities through website. Besides surveillance, allowed us increase our understanding about seasonal invasion dynamics factors contributing its spread. results will help individual growers protecting their promoting more efficient usage insecticides sustainable healthy productions.

Life tables in entomology: A discussion on tables’ parameters and the importance of raw data

PLoS ONE, Год журнала: 2024, Номер 19(3), С. e0299598 - e0299598

Опубликована: Март 7, 2024

Life tables are one of the most common tools to describe biology insect species and their response environmental conditions. Although benefits life beyond question, we raise some doubts about completeness information reported in tables. To substantiate these doubts, consider a case study ( Corcyra cephalonica ) for which raw dataset is available. The data suggest that Gaussian approximation development times implied by average standard error usually does not reliably actual distribution can be misleading hide interesting biological aspects. Furthermore, it risky when table used build models predict demographic changes population. present highlights this aspect comparing impulse generated its based on mean error. conclusions paper highlight: i) importance adding more and, ii) role ensure kind studies. Given data, also point out need further developments community sharing analysing experiments.

A bud's life: Metabarcoding analysis to characterise hazelnut big buds microbiome biodiversity

Microbiological Research, Год журнала: 2024, Номер 287, С. 127851 - 127851

Опубликована: Июль 24, 2024

Despite Corylus avellana L. being an economically important shrub species known for its resilience to adverse environmental conditions, it constantly faces attacks from a plethora of biotic entities. Among these, the mite pest Phytoptus avellanae is gaining importance, causing economic losses every year. This colonises new generative and vegetative buds, leading them become swollen reddish, drastically reducing hazelnut production. The biology behind gall formation still poorly understood. study provides qualitative quantitative description microbiome in both healthy infested buds two cultivars through metabarcoding fungal ITS bacterial 16 S. Potentially pathogenic genera such as Fusarium Pseudomonas were predominant along with obligate intracellular genus Wolbachia. Akanthomyces muscarius was instead isolated culture-based methods only buds. These findings could improve understanding ecology, supporting management populations, they also serve milestone further studies on low-impact, monitoring-driven, genetically targeted control strategies.

Integration of temperature-driven population model and pest monitoring data to estimate initial conditions and timing of first field invasion: application to the cassava whitefly, Bemisia tabaci

Journal of The Royal Society Interface, Год журнала: 2025, Номер 22(226)

Опубликована: Май 1, 2025

Empirical field data and simulation models are often used separately to monitor analyse the dynamics of insect pest populations over time. Greater insight may be achieved when directly parametrize population dynamic models. In this paper, we use a differential evolution algorithm integrate mechanistic physiological-based monitoring estimate density physiological age first cohort at start monitoring. We introduce an ad hoc temperature-driven life-cycle model Bemisia tabaci in conjunction with data. The likely date local whitefly invasion is estimated, subsequent improvement model’s predictive accuracy. method allows computation incursion by demonstrates that initial somewhat neglected prior studies can improve accuracy simulations. Given increasing availability describing terrestrial arthropods, integration prediction pioneer will lead better decision-making management.
