Special Issue Information

Dear Colleagues,

Vector-borne diseases remain a major global health concern, posing risks to human and animal populations, especially in tropical and subtropical regions. Vectors like mosquitoes, triatomines, ticks, and other arthropods are responsible for transmitting diseases such as malaria, dengue, Zika, Chagas disease, and West Nile virus, among others. The impact of these diseases on public health and the economy is substantial, necessitating the use of insecticides to control vector populations and reduce disease transmission.

Insecticides have long been a cornerstone of vector control efforts, successfully reducing the prevalence of many diseases. However, with the overuse of insecticides, resistance has developed in many vector populations. This resistance threatens the efficacy of existing control measures, increasing the likelihood of disease resurgence. The problem is particularly pronounced in resource-limited settings, where alternative tools and strategies are not always available. Tackling insecticide resistance is critical to ensuring the ongoing success of vector control programs and reducing the global burden of these diseases.

This Special Issue aims to bring together recent advances and strategies in understanding and combating insecticide resistance in vectors of both human and veterinary importance. Submissions may address, but are not limited to, the following topics:

  • Mechanisms of insecticide resistance in vectors of human and veterinary diseases—investigation of the molecular, biochemical, and genetic underpinnings of resistance in various vectors;
  • The ecological and evolutionary dynamics of resistance development—analysis of the environmental and evolutionary pressures shaping resistance patterns in vector populations;
  • Novel insecticides and biopesticides—exploration of new chemical and biological agents that offer alternative modes of action with reduced resistance potential;
  • Integrated vector management (IVM) strategies—examination of comprehensive approaches combining biological, chemical, environmental, and regulatory strategies to sustainably manage vector populations and resistance;
  • The monitoring and surveillance of insecticide resistance—emphasizing the importance of continuous resistance monitoring to inform adaptive vector control strategies;
  • The impact of insecticide resistance on vector competence and disease transmission—examination of the relationship between resistance and a vector’s ability to transmit diseases;
  • Behavioral adaptations of vectors—exploration of how vectors modify their behavior in response to insecticide pressure, reducing the effectiveness of interventions;
  • The use of synergists and rotational strategies—assessment of the role of combined or rotated insecticides in maintaining control efficacy and delaying resistance;
  • Policy and regulatory implications—discussion of the challenges posed by insecticide resistance from a policy and regulatory standpoint, emphasizing public and veterinary health.

Through this collection of research, this Special Issue seeks to provide insights into the mechanisms driving insecticide resistance while presenting innovative approaches for sustainable vector control in both human and animal health contexts.

Background: In recent decades, malaria vector species distribution and insecticide resistance have taken new colonization steps across Africa. Understanding the malaria vector insecticide resistance status, blood meal source, and species composition is of paramount importance in designing evidence-based vector control strategies. This study assessed the blood meal sources, sporozoite (infectivity) rate, and knockdown resistance allele’s frequency in female Anopheles arabiensis in chosen villages of Jabi Tehnan District, Northwest Ethiopia. Methods: The host-seeking and resting Anopheles gambiae s.l. were collected using human landing catches (HLCs), CDC light traps (CDC-LTs), pyrethrum spray catches (PSCs), and pit shelters (PSs) both indoors and outdoors. The analysis of both blood meal sources and circumsporozoite proteins was performed using enzyme-linked immunosorbent assay (ELISA). The detection of knockdown resistance gene mutations and species identification were conducted using a polymerase chain reaction (PCR). Results: A total of 5098 female Anopheles gambiae s.l. were collected. Of these, 1690 (33.2%) were collected from HLCs, 1423 (27.9%) from CDC light traps, 1635 (32.0%) from PSCs, and only 350 (6.9%) from pit shelters (PSs). Of these, 57.2% (n = 2915) female Anopheles mosquitoes were collected indoors using CDC light traps (CDC-LTs), human landing catches (HLCs), and pyrethrum spray catches (PSCs), while 38.2% (n = 2183) were collected outdoors using human landing collection (HLC), CDC light traps (CDC-LTs), and artificial pit shelters (PSs). Molecular identification to the species level showed that among the 530 An. gambiae s.l. samples analyzed using PCR, 96.03% (509) were An. arabiensis, and 3.97% (21) were unidentified species. The biting peak was found to be from 22:00 to 00:00 h for An. arabiensis. However, their activity decreased sharply after 23:00 to 00:00 h. The distribution of knockdown resistance genes in the tested specimens of An. arabiensis consisted of 1.4% (n = 3) heterozygous resistant (RS), 17.9% (n = 38) homozygous resistant (RR), and 80.7% (n = 171) homozygous susceptible (SS) genotypes. A higher proportion of Anopheles mosquitoes analyzed for blood meal analysis had a human blood meal origin at 13.1% (n = 47), followed by bovine at 8.9% (n = 32) and mixed at 5.8% (n = 21). Conclusions: The dominant malaria vector species was Anopheles arabiensis in the study area with a higher human blood meal origin. The Kdr gene was confirmed in the tested An. arabiensis, indicating that an alternative insecticide class should be used in the study area. Full article

Controlling Rhipicephalus microplus is currently one of the main challenges in livestock farming due to the significant economic losses it causes. Traditionally, managing this parasite has been based on the use of synthetic ixodicides, among which fipronil has proven to be highly effective. However, its low water solubility and the limitations of commercially available formulations can affect the bioavailability of this compound, favoring the emergence of resistance in tick populations. In this context, fipronil-loaded nanoparticles were developed using the Eudragit® E PO polymer (NP_F) (Helm, Naucalpan, Mexico, Mexico), which were physicochemically characterized and evaluated against fipronil-susceptible R. microplus larvae. NP_F had an average size of 143.43 ± 1.88 nm, a polydispersity index (PDI) of 0.162 ± 0.01, a ζ (P ζ) of 21.16 ± 0.54, an encapsulation percentage (%E) of 7.36 ± 0.30, and an encapsulation efficiency percentage (%EE) of 66.28 ± 3.5%. Free fipronil showed an LC50 of 0.582 µg/mL and an LC90 of 2.503 µg/mL against R. microplus. The NP_F formulation showed an LC50 of 0.427 µg/mL and an LC90 of 2.092 µg/mL. These results suggest that incorporating fipronil into nanoparticles improves its ixodicide efficacy, positioning it as an innovative and promising alternative for the development of effective tick control formulations.

The rapid global expansion of Aedes aegypti-borne diseases such as dengue, chikungunya, and Zika has positioned this mosquito as a key target for vector control programs. These programs rely heavily on insecticide use, leading to the widespread emergence of insecticide resistance. Understanding the molecular basis of resistance is essential for developing effective management strategies. In this study, we employed a whole-transcriptome (RNA-seq) approach to analyze gene expression in three Ae. aegypti populations from Mexico that underwent four generations of laboratory selection with deltamethrin. Several cytochrome P450 genes (CYP6AG4, CYP6M5, CYP307A1) and a chitin-binding peritrophin-like gene (Ae-Aper50) were significantly overexpressed following selection, supporting roles for both detoxification and midgut protection. We also observed a consistent downregulation of cuticular protein genes in deltamethrin-selected groups relative to the baseline populations, suggesting their involvement in baseline tolerance rather than induced resistance. Additionally, the overexpression of immune- and stress-related genes, including the RNA helicase MOV-10, indicates that insecticide selection may trigger broader physiological responses. These findings highlight complex, multi-pathway transcriptomic changes associated with resistance development in Ae. aegypti. Full article

Culex pipiens quinquefasciatus is a notorious vector transmitting severe diseases such as Zika virus and West Nile virus to humans worldwide. Vermistatin is a type of funicon-like compound and was first isolated from Penicillin vermiculatum in the 1970s. Vermistatin has shown promising activity against Cx. p. quinquefasciatus larvae in our previous research. Here, we conducted a transcriptomic analysis of Cx. p. quinquefasciatus larvae treated with a median lethal concentration of 28.13 mg/L vermistatin. Differential expression analysis identified 1055 vermistatin-responsive genes, with 477 downregulated and 578 upregulated. Gene Ontology annotation and enrichment analysis revealed the metabolic process to be the most significantly affected biological process, the membrane to be the most significantly affected cellular component, and catalytic activity to be the most significantly affected molecular function. Kyoto Encyclopedia of Genes and Genomes pathway analysis classified the differential expression genes into six major categories, with metabolism and organismal systems being the most enriched. Fifty-five pathways were significantly enriched, with the hematopoietic cell lineage, renin–angiotensin system, cholesterol metabolism, and peroxisome proliferator-activated receptor signaling pathways among the top altered pathways. Furthermore, 32 potential detoxification-related genes were differentially expressed, with 3 cytochrome P450s, 2 ABC transporters, and 1 UGT induced by vermistatin. This study provides insights into the molecular mechanisms of vermistatin’s action against Cx. p. quinquefasciatus larvae, highlighting potential targets for novel mosquito control strategies.
