Life cycle and duration on of different stages of life cycle of Tenuipalpus pernicis were studied on Psidium guajava leaves in laboratory condition. These studies reveal that its incubation period was 4.12±1.98 days, percentage of hatching 78.71±0.82 (n=10), protonymph stage 2.25±0.15 days, deutonymph stage 3.71±0.11 days, egg to adult period 9.62±0.08 days, the percentage of mortality 2.0±0.79, pre-oviposition period 2.00±0.27 days, oviposition period 4.00±0.25 days, postoviposition period 8.02±0.21 days, adult longevity 30.85±1.04 days, fecundity 11.28±0.27 eggs and the male: female sex ratio 1:1.85.
