Explanation:
Detailed explanation-1: -Nymphs have two active feeding stages, and the nymphal stage varies from 4 days to 2 weeks depending on the temperature. The pupal stage consists of the pre-pupa and pupa. The pre-pupal stage lasts for one to 2 days, and the pupal stage lasts for another one to 3 days.
Detailed explanation-2: -Thrips damage causes discoloration, distortion, premature drying, and shedding of leaves, flowers, and buds (Figures 4, 8, 9). Feeding can also impact a plant’s ability to grow, causing stunting or dwarfing. Infested fruits are discolored, deformed, and scabby (Figure 10).
