Online published on 20 December, 2024. Abstract In the present study, we surveyed five different places for the prevalence of chickpea stunt disease in Gajapati, Odisha, India and found the disease incidence (DI) in the range of 1.3 to 6.24%, respectively. The DI was found in the range of 2.65 to 38.77% on three different dates of chickpea sown crop for six intervals of 15 days each. The insect vector (Aphis craccivora) population on different dated sown crops was found to be in the range of 2.5 to 37, respectively. The acquisition feeding period (AFP) of A. craccivora started at 1 h with a value of 2.77 mean transmission and reached 23.32 mean transmission after 48 h. The inoculation feeding period (IFP) was initiated at 6 h with a value of 3.03 mean transmission and reached 27.22 mean transmission after 48 h. This study indicated A. craccivora as the potential vector influencing the health of chickpea plants.
