In this paper the biological cycle of the insect was studied in a material collected in 2004 in Andres Eloy Blanco County, Lara State, Venezuela. The study was conducted at the Entomology Laboratory of INIA-Lara, under mean temperature and relative humidity of 27.1[degree]C and 65.3 %, respectively. The average duration of the insect phases was 4.21 days for egg, 11.15 days for larvae, 2.66 days for pre-pupa, 5.29 days for pupa, and 103,3 days for adult female. The paper also describes some morphological characteristics of each phase. The following two larval instars were found: L1, with an average width of the cephalic capsule of 0.33 mm, and L2, with 0.52 mm wide. The pre oviposition period lasted 5.1 days, the egg fertility was 99.2 %, the fecundity was 43.0 eggs per adult female, and the sex ratio was 13.8 females per each male.10aHypothenemus hampei1 aFernandez, Silvestre1 aCordero, Julio  uhttps://weevil.myspecies.info/biology-coffee-berry-borer-h-hampei-ferrari-coleoptera-curculionidae-scolytinae-under-laboratory-con
