DEVELOPMENT OF METAMASIUS CALLIZONA (COLEOPTERA: CURCULIONIDAE) ON PINEAPPLE STEMS
Abstract
In the laboratory at 26°C and 14:10 L:D, female Metamasius callizona (Chevrolat) oviposited in pocket-shaped slits that they cut in pineapple leaves. Eggs were 1.98 × 0.97 mm and incubation averaged 8.3 d at 82% RH. On a diet of pineapple stem, 5 larval instars averaged 37.4 d to develop to the pupa. The pupal stage averaged 11.8 d, and the pupal weight averaged 0.12 g. Development from oviposition to adult emergence took about 8 wk.Downloads
