The reproductive capacities and development of the seed beetle  Acanthoscelides macrophthalmus  (Schaeffer) (Coleoptera: Bruchidae), found in Togo, were determined under natural conditions in a Guinean zone for its use as a substitute host for the mass rearing of the parasitoid  Dinarmus basalts  Rond (Hymenoptera: Pteromalidae), a biological agent for the control of beetles that are pests of cowpea,  Vigna unguiculata  (L.) Walpers (Fabales: Fabaceae). Population dynamics at the field level; and survival, fecundity and offspring production by  A. macrophthalmus  under laboratory conditions were measured when fed on its natural plant-host  Leucaena leucocephala  (Lamark) deWit (Fabales: Mimosaceae). The data resulting from the laboratory study were used to calculate the demographic parameters of  A. macrophthalmus  by establishing its fertility and life tables. Contrary to cultivated leguminous food plants,  L. leucocephala  is a perennial sub-spontaneous leguminous plant whose pods are available year round. Although  A. macrophthalmus  was present in nature throughout the year, its infestation rate of the pods fluctuated according to the phenology of the plant. The maximum infestation of  L. leucocephala  pods was observed between August and December. Four larval stages and one pupal stage of  A. macrophthalmus  were identified in the laboratory. The total mean development time varied on average 33.75 ± 2.87 days on the mature pods and 33.39 ± 2.02 days on seeds. The adult female lived from one to two weeks. During its life time, the female laid an average of 62.3 ± 19 and 43.1 ± 13 eggs on the mature pods and seeds respectively and produced an average of 36.7 ± 11.3 offspring on the mature pods and 21.8 ± 8.4 offspring on seeds. On seeds, the net reproduction rate was 5.88 females per female and the intrinsic rate of population increase 0.051 per day. The generation time was 34.59 days and the doubling time 13.59 days. The demographic parameters of  A. macrophthalmus  in this study are close to those of  Callobruchus maculatus  F. (Bruchidae), the natural host of  D. basalts  in a previous study.  A. macrophthalmus  could therefore be used as substitute host for the mass rearing of  D. basalts  and subsequently its release in farmers' storage containers. The data presented in this study provide some baseline information regarding the reproductive capacities of  A. macrophthalmus  that may be useful for its promotion as a substitute host for mass rearing of  D. basalts .
