Resumo: | Calacarus heveae Feres, 1992 is an Eriophyidae mite described from rubber tree (Hevea brasiliensis Muell. Arg.) in the northwest region of the State of São Paulo. This mite prefers the adaxial face of the folioles and it can reduce the brightness of the leaves, turning them progressively yellow and brownish, and consequently premature fall. The aim of this work was to study the biology of C. heveae in laboratory, on detached rubber tree folioles. The study was conducted at 28±1 ºC in the photophase (12h), 25±1 ºC in the dark phase (12h), and 90±5% relative humidity. The study was initiated with a total of 59 eggs. The average duration of egg, larva and nymph stages was 5.8, 2.0 and 1.4 days, respectively. The period from egg to adult lasted 9.3 days, and the average periods of pre-oviposition, oviposition and post-oviposition, 1.8, 6.1 and 1.2 days, respectively. The average longevity of the adult male was ca. 4.0 days, while the longevity adult female was about 8.4 days. The average daily oviposition rate was 2.3 egg per female while the average fecundity was 16.2 eggs per female.
