Global potential distribution of Drosophila suzukii (Diptera, Drosophilidae)

Abstract

Drosophila suzukii (Matsumura) is a species native to Western Asia that is able to pierce intact fruit during egg laying, causing it to be considered a fruit crop pest in many countries. Drosophila suzukii have a rapid expansion worldwide; occurrences were recorded in North America and Europe in 2008, and South America in 2013. Due to this rapid expansion, we modeled the potential distribution of this species using the Maximum Entropy Modeling (MaxEnt) algorithm and the Genetic Algorithm for Ruleset Production (GARP) using 407 sites with known occurrences worldwide and 11 predictor variables. After 1000 replicates, the value of the average area under the curve (AUC) of the model predictions with 1000 replicates was 0.97 for MaxEnt and 0.87 for GARP, indicating that both models had optimal performances. The environmental variables that most influenced the prediction of the MaxEnt model were the annual mean temperature, the maximum temperature of the warmest month, the mean temperature of the coldest quarter and the annual precipitation. The models indicated high environmental suitability, mainly in temperate and subtropical areas in the continents of Asia, Europe and North and South America, where the species has already been recorded. The potential for further invasions of the African and Australian continents is predicted due to the environmental suitability of these areas for this species.

Not berry hungry? Discovering the hidden food sources of a small fruit specialist, Drosophila suzukii

“…Furthermore, this resource‐switching ability may be associated with its success as an invasive species. Given the finding shown here, in concert with our previous reports on the plasticity of thermal susceptibility in this species, we can speculate that continued range expansion is likely as this species appears readily adaptable to novel environments (dos Santos et al, ; Stockton et al, ).…”

Interactions among morphotype, nutrition, and temperature impact fitness of an invasive fly

“…In this study, we explore the interactions among nutrition, environmental stressors, and phenotype in an economically relevant invasive species, the spotted‐wing drosophila Drosophila suzukii Matsumura (Diptera: Drosophilidae). Drosophila suzukii originated in temperate Asia and has successfully invaded North America, South America, and Europe since its first detection outside its native range in 2008 (Dos Santos et al, ; Lee et al, ; Walsh et al, ). This agricultural pest poses a threat for berry and cherry production, as females possess a serrated ovipositor which enables them to lay eggs inside ripening fruit (Karageorgi et al, ).…”

Optimization of a wheat germ diet for mass rearing Drosophila suzukii

“…The spotted wing drosophila is widespread in America, Asia, and Europe (Asplen et al, 2015), but computer simulations based on climatic data -Genetic Algorithm for Ruleset Production (GARP) and Maximum Entropy Modeling (Maxent)indicate that its potential niche is throughout current tropical and warm temperate regions of the world (dos Santos et al, 2017). In this possible scenario of wide distribution and its inherent economic losses, the use of native parasitoids represents a good option to reinforce the methods of prevention and control.…”
