Abstract

The life cycles of two phycitid moths, Plodia interpunctella (Hubn.) and Ephestia cautella (Wik.) were studied under ambient laboratory conditions on groundnut, maize, sorghum, wheat and standard medium (maize/wheat/glycerol, 8:8:1, w/w). Egg hatchabilities were found to be 98.6 and 91.6% for P. interpunctella and E. cautella respectively. Five larval instars were recorded for each species based on head-capsule width measurements. The growth ratios of the larval head-capsule width ranged from 1.08–1.72 in P. interpunctella: and 1.33–1.57 in E. cautella. These ranges fall within the acceptable range in Dyar's rule. Mean fecundities ranged from 96.83 ± 0.31 on wheat to 190.87 ± 0.47 on standard medium for P. interpunctella; and 96.83 ± 0.31 on groundnut to 192 ± 1.33 on standard medium for E. cautella. Mean developmental periods of the two moths on the selected food media ranged from 25.65 days on standard medium to 46.11 days in broken wheat for P. interpunctella; and 26.95 days in broken sorghum to 40.14 days in ground maize for E. cautella.

Résumé

Les évolutions de deux papillons phycitids, Plodia interpunctella (Hubn.) et Ephestia cautella (Wlk.) etaient etudiées sous conditions ambiance de laboratoire, sur arachide, maïs, sorgho, blé et moyen standard (maïs/blé/glycerol, 8:8:1, w/w). Les éclosions des oeufs etaient de 98,6 et 91,6 % pour P. interpunctella et E. cautella respectivement. Ona noté cinq phases morphologiques larvaires pour chaque espèce basés sur les mesures des largeurs des têtes. L'accroissement raison des largeurs des têtes rangé de 1,08 à 1,72 en P. interpunctella, et de 1,33 à 1,57 en E. cautella. Ces ranges se conformaient à la loi de Dyar. Les moyennes de fecondité rangées de 96,83 ± 0,31 sur le blé à 190,87 ± 0,47 sur la diète standarde pour P. interpunctella et de 96,87± 0,47 sur arachide à 192 ± 133 sur la diète standarde pour E. cautella. Les periodes moyennes developpement des deux papillons sur les marchandises selectionnées rangées de 25,65 sur la diète standarde à 46,11 jours en blé cassé pour P. interpunctella; et de 26,95 jours en sorgho cassé à 40,14 jours en maïs broyé pour E. cautella.
