Abstract

Eotetranychus cendanai Rimando was found on six different citrus species of which one is new host record: Citrus hystrix DC., Citrus aurantifolia Swingle, Citrus reticulata Blanco, Citrus maxima (Burm. f.) Merr., Citrus madurensis Lour. (new record) and Murraya paniculata (Linn.) Jack in 34 provinces of Thailand. Studies on life history of E. cendanai on 5 different host plants were conducted at 28±1 °C and 58±5 % RH. The egg, larva, protonymph and deutonymph stages on 5 different host plants ranged 4.9–5.8, 1.9–3.0, 1.9–2.6 and 1.8–2.7 days, respectively. Completion of the life cycle required 11.2–14.0 days. A fertilized female lived 6.55–10.52 days and produced 6.30–26.38 eggs (0.96–2.43 eggs/day). Fertilized females produced offspring with a sex ratio of male: female 1:1.02–1:2, whereas unfertilized females produced only male offspring. Longevity of an unfertilized female lasted 7.52–11.62 days and 14.35–17.73 eggs (1.40–1.97 eggs/day) were laid per female. A life table study of E. cendanai indicated that net reproductive rate of increase (Ro) = 14.1 times, cohort generation time (Tc) = 17.37 days, intrinsic rate of increase (rm) = 0.156 individual/day and finite rate of increase (λ) = 1.165. Major mortality occurred during the larval stage followed by the nymphal and egg stages.
