Life history of Polyphagotarsonemus latus (Banks) feeding on lemon, tea and pepper.
The arrhenotokous tarsonemid Polyphagotarsonemus latus was reared on young leaves of lemon, tea and pepper [? Capsicum] at 25°C and LD 13:9. The development period from egg to adult averaged 3.5 and 3.2, 3.6 and 3.9, and 4.1 and 4.1 days for males and females on the 3 food plants, resp. Adult female and male longevity was 8.8 and 4.2, 15.5 and 17.9, and 11.4 and 15.3 days, resp, and females laid 42, 58 and 25 eggs, resp. The female/male sex ratio was 2.2, 2.6 and 2.8 in the laboratory, and 1.8, 2.5 and 2.3 on seedlings in the greenhouse. Although the shortest development period was observed on lemon, adult longevity, fecundity, sex ratio and body width were greatest when fed on tea.
