The biology of Diatraea flavipennella (Lepidoptera: Crambidae) reared under laboratory conditions
Florida Entomologist 90 (2), 309-313
Abstract: Aspects of the biology of the sugarcane pest Diatraea flavipennella (Box 1931) (Lepidoptera: Crambidae), locally named broca-pequena da cana-de-açúcar, reared and maintained under laboratory conditions and fed on an artificial diet have been investigated. The larval stage, which involved 7 instars, continued for a mean period of 34.87 d. Each instar could be characterized by the size of the cephalic capsule, which increased 1.28-fold on average between instars. The mean duration of the pupal stage was 12.75 d. The pupae exhibited sexual dimorphism in that the females were larger than the males, while the latter exhibited a genital pore that was absent in the females. In adult insects, the female/male ratio was 1:1.3. Adult females were on average 28.73 mm in size while the mean value for adult males was only 20.80 mm. Females commenced oviposition on the first d of their adult life and were able to oviposit until d 6. On average each female produced 431.05 eggs during her lifetime, although the majority of eggs were deposited during the first 2 d after emergence.
