Abstract

:
Plecia nearctica Hardy, commonly referred to as lovebugs, is a species of march fly with a subtropical American distribution. The northern range limits of P. nearctica could alter due to climate change, which is a worldwide issue. It has been reported that flowers utilized by P. nearctica are not visited by pollinators, which may negatively impact foraging activity particularly when resources are limited. This study used 933 occurrence records of P. nearctica in the USA to predict its potential range expansion by 2050. To predict potential habitat change we applied well-established modeling procedures using both MaxEnt and geographical information system (GIS). Six environmental variables, two climate models, and two Shared Socio-economic Pathways (SSP126 and SSP585) were used in the analysis. The model performance was excellent with a high True Skilled Statistic (=0.75) value. The predicted potential distribution and range expansion of P. nearctica in 2050 includes the Gulf Coast and the Southeastern and Western regions of the USA. However, results suggest that most of the Central and Northern USA are unlikely to provide suitable habitat for this pest and have no reason for concern about interactions between pollinators and P. nearctica.

1. Introduction

The western honey bee (Apis mellifera L.) provides significant pollination services for many agricultural crops and wild plants around the world [1,2,3,4,5]. Honey bees have been intentionally transported by humans to every continent (with the exception of Antarctica) to provide pollination services [6]. As a result, they are now cosmopolitan in most landscapes and often move into agricultural areas when plants are in bloom to augment existing communities of pollinators. Recent estimates suggest that within the USA alone, pollinator-dependent crops are valued at more than $50 billion dollars/year [7,8].
Interspecies interactions among floral visitors is known to alter pollinator behavior, though there is a stark lack of information about the influence of community composition on pollination services [3]. Studies indicate that interactions between honey bees and wild or native bees are synergistic, leading to an overall increase in pollination services in some crops [9]. Other studies suggest that interspecies interactions could be antagonistic, with pollination services interrupted by the presence of other insects on flowers [10,11]. Anecdotal reports from beekeepers suggest that honey bees do not visit flowers with lovebugs (Plecia nearctica Hardy, Diptera: Bibionidae) on them [12], suggesting that this antagonistic interspecies interaction likely negatively affects pollination and should be further investigated.
Lovebugs are native to Central America and are considered an invasive pest in the Southeastern United States. The geographical distribution of P. nearctica in the USA is currently limited to the Southeastern states from Texas and Arkansas east to South Carolina [12,13], although this distribution could be expanded by future climate changes allowing invasion of other regions within the country. Lovebugs are attracted to floral and aromatic volatiles including phenylacetaldehyde, anethole, and anisealdehyde [14,15,16]. In most of their current range, lovebugs are bivoltine with a third smaller generation in parts of Florida, with peak activity generally observed from April–May and August–September [17,18].
Climate change can influence the distribution of species through both direct and indirect methods. Several recent studies have been conducted to predict changes in habitat suitability for pests that threaten humans, farm animals, agriculture, and apiculture [19,20,21,22,23,24,25,26]. These studies were performed by analyzing occurrence records from available online sources followed by utilizing specific modeling software, such as MaxEnt [20,25,26,27,28,29,30]. Additional analysis depends on the use of the geographical information system (GIS) to perform additional steps on the model [20,23,24,31,32,33].
Environmental variables from ecological datasets are used in modeling to predict future changes in habitat suitability [26]. In particular, temperature and humidity can provide good predictions of potential habitat change for agricultural pests. Unfortunately, changes in agricultural crops and landscape are not available in future climate models; therefore, they are not being incorporated in the modeling studies [25]. Additionally, changes in climate can cause invasion of some pests to new regions. Such invasive species could cause problems to beneficiary pollinators, especially bees [34]. For example, Small Hive Beetle (SHB), Aethina tumida Murray, is usually considered a benign pest in Africa but has become a widespread species causing damage to apiculture industry outside of its native range, with its range expanding due to climate change [35,36,37].
Ecological modeling is a standard method that has been applied by scientists from different disciplines and can predict the habitat suitability of organisms facing climate change. This study was performed to predict the potential habitat suitability for P. nearctica and its future distribution in the USA. The results of this study can help to predict the potential distribution and range change of P. nearctica until 2050. Additionally, we provide suggestions for further investigations regarding the potential impacts of P. nearctica on insect pollinators, especially honey bees.

2. Materials and Methods

2.1. Occurrence Data

The available records for lovebugs, Plecia nearctica, in the USA were downloaded from Global Biodiversity Information Facility (GBIF) (GBIF.org on 14 December 2021, https://doi.org/10.15468/dl.rnrndb). A total of 933 records (2010–2021) were used in the study and were mainly from the Southern USA. These records were visualized using DIVA-GIS 7.5.0 (https://www.diva-gis.org accessed on 14 December 2021) to remove any repeated or incorrect records (Figure 1).

2.2. Environmental Variables

The commonly used source for environmental variables is worldclim.org, which we used (WorldClim version 2.1) to obtain the available 19 variables at 5 km2 spatial resolution [38], representing a 30-year period (1970–2000). These variables were used to understand the historic/current distribution of P. nearctica within the study area. Two analyses were performed to select the most important variables [23,25]: (1) the jackknife test was performed using MaxEnt v 3.4.1 [39] and the 19 variables to determine the most important variables with regularized training gain more than 1 (Supplementary Material Figure S1), (2) Species Distribution Modeling (SDM) was used to remove highly correlated variables in ArcGIS 10.8 with correlation threshold of 0.8. Finally, six variables were selected to perform the analysis (Table 1).
The same six variables for future conditions during 2050 (2041–2060) were obtained from the Coupled Model Intercomparison Project Phase 6 (CMIP6) [40] for two climate models (Table 2). The low and the high levels of Shared Socio-economic Pathways (SSP126 and SSP585) were selected from each model to perform the future predictions. More details about the models and their websites are available in the Supplementary Materials (Supplementary Information: Figures S1 and S2).

2.3. Habitat Suitability Modeling Using MaxEnt

Environmental variables were prepared to cover the current USA using the shape extraction tool in ArcGIS 10.8 (Environmental Systems Research Institute, Inc., Redlands, CA, USA). The variables were then analyzed using MaxEnt v 3.4.1 [39]. Specific parameters were selected to run the modeling analysis according to previous studies [26] (Table 3).

2.4. GIS Analysis

The model outputs from the MaxEnt were visualized using ArcGIS 10.8 [24,25,26]. The maps from the modeling study were classified in the GIS into four suitability classes [26] as rarely, moderately, highly, and very highly suitable for the prevalence of P. nearctica in the study area. Two spatial analysis tools (Raster calculator and Reclassify) were used in the GIS to obtain the final maps: a map for historic/current conditions, another map for SSP126, and a map for SSP585. The averages of the two future models (BCC-CSM2-MR and MRI-ESM2-0) were calculated to obtain future maps of SSP126 and SSP585. In addition, we represent the overall average of SSP126 and SSP585, using the GIS of the future habitat suitability for P. nearctica. The gain/loss map was also established to show the variations between current and future habitat suitability for P. nearctica.

2.5. Contribution Percentages and Model Performance

The outcomes from the ecological model (MaxEnt results) were used to evaluate its performance [24,25,26]. First, the contribution of each variable in the model was presented to highlight the most effective variable. Then, the following parameters were used to judge the performance of the model: area under the curve (AUC) of the receiver operating characteristics (ROC), rates of omission/commission, and jackknife test values for the variables contributed to the analysis. The accuracy of the used model was tested using a common test of the True Skilled Statistic (TSS).

3. Results

3.1. Contribution Percentages and Model Performance

The environmental variables bio1, bio13, bio6, bio7, bio4, and bio10 contributed to the model by 52.4, 21.1, 18.9, 6.3, 0.7, and 0.6%, respectively. So, the highest contribution was to annual mean temperature followed by precipitation of the wettest month. Temperature variables contributed to the model by 70.9%, while the precipitation variable contributed 21.1%. The area under the curve (AUC) for the used model was high (0.935 ± 0.006), as shown in Figure 2. In addition, the AUC for each of the used variables were higher than 0.88 (Figure 3). The other outputs from the model are presented in the Supplementary Materials (Figures S2–S10). From these figures, the omission rate was close to the predicted omission (Figure S2), and the jackknife values for the regularized gain (Figure S3) and test gain (Figure S4) were high (>1.1). The response curves for variables that were used in the analysis showed that the ideal range for each variable was approximately 20–25 °C for bio1 (Figure S5), 400–500 for bio4 (Figure S6), 10–13 °C for bio6 (Figure S7), 22–25 °C for bio7 (Figure S8), 27–28 °C for bio10 (Figure S9), and 195–205 mm for bio13 (Figure S10). The true skilled statistic (TSS) was equal to 0.75.

3.2. Historic/Current Distribution of Plecia nearctica

The map (Figure 4) shows the “very highly suitable” Southern states, in particular all of Florida and some parts of Georgia, Alabama, Mississippi, Louisiana, and Texas for P. nearctica. These states in addition to South Carolina and some parts of North Carolina are highly suitable for the occurrence of this pest. The moderately suitable areas occur in some states including North Carolina, Virginia, West Virginia, Kentucky, Tennessee, Missouri, Arkansas, Oklahoma, and Texas in the east and some areas in Arizona, California, Oregon, and Washington in the west. The rest of the USA is not likely to be highly suitable for P. nearctica. It seems that warm conditions are perfect for the prevalence of P. nearctica.

3.3. Prediction about Future Suitable Habitat for Plecia nearctica

The two future scenarios using two climate models and two levels of SSP (Figure 5) show more areas in the South, especially Eastern states, will be highly suitable for P. nearctica. No huge changes in the high suitable areas are expected than current conditions based on SPP 126 and 585. The noticeable variations between the two levels of SPPs are in the moderately suitable areas. More areas are expected to be moderately suitable in case of SPP 126, which covers parts of the Northern USA, such as Michigan and Idaho, unlike SPP 585.
The overall average of the two climate models and the two levels of SPP are presented in one map (Figure 6). This map represents the predicated future habitat suitable for P. nearctica in the USA based on the used models and parameters. According to this map, the very highly suitable and highly suitable areas will cover most parts of the Southeastern states in addition to some parts of California. The moderately suitable areas will contain more areas than current conditions. The Northern and Central USA are expected to remain less suitable for the prevalence of this pest.

3.4. Gain/Loss Due to Climate Change

The very highly suitable areas (Figure 7) are expected to increase due to climate change especially, some parts of Georgia, Alabama, Mississippi, Louisiana, Texas, and South and North Carolina in addition to areas of Central California. The potential habitat loss due to climate change would primarily be observed in South and Central Texas. More areas are expected to be moderately suitable for P. nearctica (Figure 8) due to climate change than very highly or highly suitable areas.

4. Discussion

The most important variables for the prevalence of P. nearctica in the study area were temperature related. This was clear from the high contribution of specific variables in the model, especially annual mean temperature, which contributed to the overall fit of the model by 52.4%. The suitable range of temperature across all variables ranged from 10–28 °C. High precipitation is also important for the prevalence of this pest. This explains the presence of this pest primarily in the Southern USA, where high temperature and moderate to high relative humidity levels exist. The model showed high performance with a very good fit based on the values of AUC, which was higher than 0.75 [21,24,25,26,41]. In addition, the TSS value was high which indicates the excellent performance of the model as values equal or above 0.5 are acceptable [25]. In addition, the omission rate was close to the predicted omission, supporting the high performance of the used model.
The map for historic/current distribution is typically fit with the distribution of used occurrence records in the USA. Another map (Figure S11) shows the density of occurrence records (dots per area), which supports the high suitability of the Southeastern areas of USA to this pest, indicating the accuracy of the. The model also predicts the suitability of other areas in addition to the current range, including South Carolina and some parts of North Carolina. Moderate suitable areas are expected to be inhabited by this pest at any time but with less prevalence than the other areas (those that are highly and very highly suitable). Such expectation is in line with previous studies on other insects, such as small hive beetles [26], large hive beetles [23], the facultative parasitoid Megaselia scalaris [20,24], and Asian hornets [19]. It seems that warm and humid conditions found in coastal subtropical areas are more suitable for this pest than other areas.
Two scenarios presented that look forward support the potential spread of P. nearctica to new areas and an expansion in geographic range. However, the Central USA is not expected to have high invasions/populations of this pest due to the less suitable environmental conditions. This model predicts a limited expansion of the very high and highly suitable areas for this pest, while the moderate suitable areas will be expanding the most. The Gulf-South and Southeastern coastal regions are expected to be the regions most infested with this pest. The two SSPs used in the model were similar in their results except in regard to the moderately suitable areas.
Lovebugs are well known as a public nuisance due to acidic body chemistry and their enormous numbers near highways in particular [12,18]. Studies on this insect are surprisingly limited but include works on their biology [18], flight behavior [42], reproductive biology [43], sexual selection [44,45], and attraction to floral lures [14]. Its larvae feed on decaying vegetation [18] and can be associated with turfgrass [46]. Mature larvae pupate in the soil for between 7 and 9 days, emerging into adults, wherein the males then compete for females [43]. Adult lovebugs are present in large numbers between May and September [17,47], when pollinators are also frequently active. If present, any potential negative effects on foraging behavior of bees would be anticipated during this period. Due to the tendency of lovebugs to occupy flowers for long periods of time and prevent other pollinators from collecting nectar or pollen [18], there may be a resulting shortage of food resources for pollinators, particularly in areas where there are limited floral resources. However, there is no existing data to measure the damage cause by range expansion of P. nearctica, or widescale complaints from beekeepers other than anecdotal reports. It is possible that this potentially negative interaction occurs regularly and remains undocumented in the literature. Future work should examine potential interactions between honey bees and this pest in the Gulf-South and Southeastern USA, regions known to have high populations of lovebugs. In areas where P. nearctica may become problematic for pollinators, there are potential control options available, including the use of natural enemies [48] and pathogenic fungi (Tolypocladium cylindrosporum, Metarhizium anisopliae, Beauveria bassiana) [49]. Additionally, mechanical traps have been developed to be used to control their population [50]. An ecologically sensitive and bee-friendly integrated pest management plan for control would help in reducing populations of this pest with minimal impact on pollinators.

5. Conclusions

In this modeling study, the potential spread of P. nearctica in the USA at two time points utilizing two climate change scenarios was explored. The model performed well considering the environmental variables and evaluation parameters. The results for habitat suitability for current conditions fit the existing distribution of P. nearctica quite well. On the other hand, results for future distribution showed a limited range expansion and spread of P. nearctica toward Central and Northern regions of the USA. Generally, the Southern USA is expected to be the hot spot for P. nearctica. In the future, more studies should be pursued on the inter-species interactions between P. nearctica and insect pollinators, including honey bees. In addition, these interactions between P. nearctica and bees should be explored to determine whether they are synergistic or antagonistic.
