A strain of small Oryzaephilus surinamensis (L.) (Coleoptera, Silvanidae) from the Far East

Rearing method of Oryzaephilus surinamensis (L.) (Coleoptera, Silvanidae) on various wheat grain granulometry

“…Jacob & Fleming (1989), studying some biological aspects of O. surinamensis, found that egg incubation was 6.6 days, larval period was 21.5 days, and pupae took 9 days to complete development; the total period was 37 days from egg to adult, what was similar to the results obtained from this research. Similar results for the total biological cycle were found by Beckett & Evans (1994) and Aitken (1966).…”

“…It means that the incubation period was up to five days and that is the period that yields the largest number of eggs. Howe (1956) and Aitken (1966) showed that O. surinamensis females can lay up to ten eggs per day during 265 days. Table IV.…”
