Table 1 Centers of Disease Control and Prevention (CDC) bottle bioassay using deltamethrin on field-collected Culex quinquefasciatus in Abu Dhabi, UAE.

Code	Location	Main Region	Test date^a	Resistance status	Time to 100% mortality (min)
1	Al Nahyan	Coastal	1 May	Resistant	> 120
2	Al Manhal	Coastal	26 February	Susceptible	60
3	Al Bateen	Coastal	2 March	Susceptible	60
4	Madinat Zayed	Inland-Desert	16 March	Susceptible	60
5	Masakin	Oman border	18 April	Susceptible	60
6	Al Nabbagh	Oman border	28 April	Susceptible	60
7	Mbazzarah Al Khadra	Oman border	24 February	Susceptible	60
8	Central District	Oman border	10 March	Susceptible	60

Mortality was checked at 15-min intervals post assay initiation, up to 2 h (0, 15, 30, 45, 60, 75, 90, 105 and 120 min) at a diagnostic dose 0.8 µg /bottle. The 60 in the table indicates that field-collected Cx. quinquefasciatus mosquitoes reached 100% mortality in under 60 min, matching the diagnostic time for lab-reared susceptible Cx. quinquefasciatus.
^a All test dates were in 2023.
