Abstract
Background objectives: Dengue is one of the most significant vector-borne diseases and is gradually becoming a global burden. The present study focused on the effect of the time of day and delayed blood feeding on the reproductive behavior of Aedes aegypti , since knowledge on such behavioural facts is still unclear.
Methods: The study was conducted using a series of in-lab experiments conducted using female mosquitoes from a well-established mosquito colony maintained in the insectary. Mated female mosquitoes were blood-fed using four different time intervals. They were experimentally tested for the effects of the time of day of blood feeding and for delayed blood feeding on clutch size, egg viability, pupal duration, pupal mortality, and adult longevity of Ae. aegypti .
Results: The time of day of Ae. aegypti blood feeding significantly influences the eggs clutch size of Ae. aegypti . The lowest egg production observed in mosquitoes feeding between 10.00 and 12.00 hours and the feeding blood in the early morning (6.00 - 8.00 am) show much higher clutch sizes than all other groups. The blood feeding during 6.00 - 8.00 a.m. and 10.00 - 12.00 a.m. had a strong positive correlation with clutch sizes of Ae. aegypti . The blood meal's quality and related nutritional components have an impact on the longevity and general fitness of the progeny of Ae. aegypti . The clutch sizes depend on the age of Ae. aegypti . The delayed blood feeding does not affect the life story parameters of Ae. aegypti .
Interpretation conclusion: Findings highlight the resilience of Ae. aegypti to variations in maternal blood-feeding patterns in shaping mosquito development, and this knowledge provides valuable insights for improving efficient and targeted approaches to controlling the dengue vector, Ae. aegypti .
