Drosophila S2 cells (Invitrogen) were cultured at 25°C in Schneider's Drosophila medium (GIBCO), supplemented with 10% heat inactivated foetal calf serum, 2mM L-glutamine, 100 U/ml penicillin, and 100 mg/ml streptomycin. Firefly (Photinus pyralis) and Renilla reniformis luciferase sequences from the plasmids pGL3 and pRL-CMV (Promega) were cloned into pMT/V5-HisB (Invitrogen), generating pMT-Luc and pMT-Ren allowing Copper-inducible expression from a metallothein promoter.
Transfections were performed using Effectene transfection reagent (Qiagen) according to the manufacturer's recommendations. Luciferase expression was assayed using the Dual-Luciferase Reporter Assay System (Promega) and analyzed on a Tecan Ultra-evolution platereader. Double stranded RNA was generated by in vitro transcription from T7 promoter flanked PCR products. Viral stocks were prepared on low passage S2 cells and titered by end point dilution. Briefly, 25.000 S2 cells per well in a 96 well plate were inoculated with 10-fold dilutions of viral stocks. Cells were transferred to fresh medium at day 7 and CPE was monitored visually over 14 days. Viral titers were calculated according to the method of Reed and Muench.
Recombinant Sindbis virus expressing GFP during viral replication was generated by cloning enhanced GFP into the XbaI site of the double subgenomic Sindbis vector pTE3′2J (kindly provided by C. Rice)1 (link). The resulting plasmid was linearized and in vitro transcribed using the mMessage machine kit (Ambion). RNA was purified and electroporated into BHK-21 cells and supernatant was harvested and virus title determined by plaque assay on BHK cells.

Sindbis virus expressing enhanced GFP (SINV-GFP) was produced by transfecting in vitro transcribed RNA from the pTE3’2J with GFP inserted into the XbaI site into BHK cells [15 (link),77 (link)]. SINV-GFP was titered on BHK cell monolayers via plaque assay. SINV-GFP (3,750 plaque forming units (PFUs)) was diluted in buffer (2 μl of 10 mM Tris, pH 7.5) and injected into the thorax using a Harbo syringe (from Honey Bee Insemination Service; www.honeybee.breeding.com/HarboAssembly.html) equipped with disposable borosilicate needles made from capillary tubes (0.8-1.10 x 100 m) using a micropipette puller (Sutter Instruments Model P-87). Honey bees were immobilized via incubation in a cold room (4°C) for 20 minutes and with insect pins and forceps during injection; after injection bees recovered at room temperature within 5 minutes. Honey bees were infected with 3,750 PFUs of SINV per bee. This virus dose is modest compared to Drosophila studies which typically utilize 250-2500 PFUs per fly; a newly emerged female worker honey bee (~150 mg) weighs ~ 200x more than an adult female fruit fly (0.8 mg)[15 (link)]. This dose allowed for a natural progression of infection over the course of the experiment and at 3-days post-injection (p.i.) virus abundance could be easily assessed by microscopy and Western-blot analysis. Virus was either injected alone or in conjunction with dsRNA (1 μg).

MRC-5 cells (human lung fibroblasts, ATCC-CCL-171) were cultured essentially as described previously [30 (link)]. Vero E6 cells (African green monkey kidney epithelial cells), 293/ACE2 cells (originally described to be derived from human HEK293 cells [95 (link)], but most likely from nonhuman primate origin [14 (link)]) and BHK-21 cells (baby hamster kidney fibroblasts) were cultured essentially as described previously [21 (link)]. Vero cells (ATCC-CCL81) cells were cultured essentially as described previously [96 (link)]. All culture media contained 100 IU/ml penicillin and 100 ug/ml streptomycin unless otherwise specified.
CHIKV LS3 is a synthetic Chikungunya virus based on the consensus sequence of E1-226V isolates [21 (link)]. Infections with CHIKV LS3 and LS3-GFP were performed essentially as described previously [21 (link)]. The Chikungunya replicon was derived from CHIKV LS3 by replacing the structural genes with a puromycin resistance/foot-and-mouth disease virus 2A oligopeptide/green fluorescent protein (PAC-2A-GFP) reporter gene. The sequence of the 2A oligopeptide contains an amino acid motif that prevents formation of the peptide bond between glycine and the final proline of the sequence which allows expression of multiple proteins from a single ORF [97 (link),98 (link)].
Vero E6 cells were infected with the Sindbis virus (SINV) HR-strain [99 (link)], Semliki Forest virus (SFV) strain SFV4 [100 (link)] or VEEV vaccine strain TC-83 [101 (link)] at a multiplicity of infection (MOI) of 5 or 10. Vero E6 cells were infected with a GFP-expressing recombinant human adenovirus type 5 (HAdV-GFP/LUC; [102 (link)]) at an MOI of 5 and with a GFP-expressing recombinant coxsackie B3 virus (CVB3) (a kind gift from prof. dr. Frank van Kuppeveld, Utrecht University) at an MOI of 1. BHK-21 cells were infected with the equine arteritis virus (EAV) Bucyrus strain at MOI 5 at 39.5°C essentially as described previously [103 (link)].

Sendai virus (SeV) Cantell strain was purchased from ATCC (#VR-907). SeV viral titer was determined by plaque assay using LLC-MK2 cells. Cells were plated and infected with SeV in 200 μL of serum-free medium for 1 h for adsorption. Then, LLC-MK2 cells were overlaid with agarose (0.45% in culture media supplemented with 5 µg/mL acetylated trypsin). After 5 days, cells were fixed with trichloroacetic acid (10%) for 30 min, stained with crystal violet (0.1% crystal violet / 25% EtOH) for 5 min, and counted to determine viral titer. Sindbis virus (SINV) Ar-339 strain was purchased from ATCC (#VR-1585). SINV viral titer was determined by plaque assay using Vero cells. Cells were plated into 6 well dished and the adsorption of the virus was performed for 1 h at 37 °C in 200 µL of virus diluted in serum-free DMEM. Then, Vero cells were overlaid with agarose (0.45% in culture media). Poliovirus type 1 (PV) (Mahoney strain) was obtained from Dr. Eckard Wimmer at Stony Brook University, New York. PV viral titer was determined by plaque assay using HeLa cells. Cells were plated into 6 well dished and adsorption of the virus was performed for 30 min at room temperature in 200 µL of virus diluted in serum-free DMEM. Then, cells were overlaid with agarose (0.45% in culture media).

Adult female Ae. aegypti (2–3 days post emergence) were infected with SINV strain MRE-16, and p5’dsMRE16ic-mCh-Flag and p5’dsMRE16ic-AaBec-mCh-Flag by intrathoracic injection. Briefly, each mosquito was cold-anesthetized using a cooling plate and injected with ~10,000 focus-forming units (FFU) of the selected viral strain in a total volume of 100 nL. Microinjected mosquitoes were placed in cardboard cages with ad libitum access to 10% sucrose solution and maintained in the insectary under the same conditions as listed above. After 5 and 7 days post injection (dpi), mosquitoes were sacrificed by overexposing them to triethylamine (Sigma, St. Louis, MO, USA) and placed in 2 mL tubes filled with 1 mL of mosquito diluent (20% heat-inactivated fetal bovine serum (FBS) in Dulbecco’s phosphate-buffered saline (PBS), 50 μg/mL penicillin/streptomycin, 50 μg/mL gentamicin, and 2.5 μg/mL fungizone) and a single zinc-plated steel 4.5-mm bead (Daisy, Rogers, AR, USA). Experimental infections were completed across two replicate batches using the same viral stocks and two subsequent mosquito generations. The results of both replicates were pooled for analysis. A total of 83 mosquitoes were analyzed in the SINV-WT group (46 at 5 dpi and 37 at 7 dpi), 74 mosquitoes in the SINV-mCh-Flag group (46 at 5 dpi and 37 at 7 dpi) and 68 mosquitoes in the SINV-AaBec-mCh-Flag group (26 at 5 dpi and 42 at 7 dpi). Mosquito samples were homogenized at 30 Hz for 2 minutes using a TissueLyser II (QIAGEN GmbH, Hilden, Germany) and centrifuged for 60 s at 11,000 rpm. All samples were further tested for the presence of viral infectious particles by focus forming assay as previously described with one minor modification: viral antigens in infected cells were labeled using Sindbis virus immune ascetic fluid (VR-1248AF; 1:500 dilution). 49 (link) Virus titers were calculated and expressed as FFU/mL. Data were analyzed using GraphPad Prism version 8.4.3. Kruskal Wallis tests were used to compare viral titers across mosquito groups.

From brains injected with sindbis virus, tissue was sectioned at 200 μm on a Leica 3050S cryostat that had been cleaned with RNAseZap prior to use. Sections were collected over dry ice and stored at −80°C prior to dissection. Cortical areas were then dissected according to sulcal landmarks over dry ice. The areas that were collected and our operational definitions of their boundaries can be found in this table.
Samples from each area were combined across 3 sections in the anterior/posterior plane into 1.5-ml Eppendorf tubes, which were stored at −80°C prior to shipping frozen on dry ice for sequencing.
