“…The mean total period for development from egg to adult was about 35 days. 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).…”

“…Although the biology of O. surinamensis has been studied by many authors (Howe 1956(Howe , 1965Fleming 1988;Collins et al 1989;Jacob & Fleming 1989;Mason 1996), the rearing process to get good production of offspring is still a challenge because of the small size of the insect and its high mobility. Oryzaephilus surinamensis prefers cereal food than oil seeds to feed on (Sinha 1971;LeCato & McCray 1973;Nakajima et al 1996).…”

“…In our system, development lasts ϳ3, 13, and 5 d for the egg, larval, and pupal stages, respectively. A number of studies of O. surinamensis have characterized reproduction and mortality at various temperatures and humidities and in various grains (Back 1926, Thomas 1940, Howe 1956, Prus 1966, Ciesielska 1990, Jacob and Fleming 1989, Beckett and Evans 1994. Bancroft (2001) has previously measured the rates of oviposition, mortality, and dispersal in response to conspecific density.…”

This research used a model experimental system to explore the joint effects of resource fragmentation and resource deterioration on population dynamics. The system provides a rapid test of conservation theory and can aid in planning for large and expensive studies. The investigation subjected the sawtooth grain beetle, Oryzaephilus surinamensis (L.), to five experiments in which population abundance was monitored over time. Metapopulations were created by connecting adjacent vials of flour with rubber tubes. The metapopulations were arranged in rings, and food was replenished at two‐week intervals. The experiments examined populations in (1) habitats becoming increasingly fragmented, (2) dynamically fragmenting structure with concurrent loss of resources over time, (3) static structure, dynamic resource loss and differing numbers of patches, (4) static structural arrangements with dynamic resource loss that mimic resource deterioration and destruction, and (5) static arrangements of connected fragments with an equal total amount of food in a few large patches or several small patches. Time series of stage‐specific abundances were compared in repeated‐measures ANOVA. The results show that populations respond in nonlinear ways to both the amount of food and area provided. Within a confined area, when food is plentiful, individual interaction limits population abundance. When the amount of food is reduced, population abundance becomes food dependent. Immediate increase in immature abundance was a characteristic of fragmentation while a delayed reduction of adults was characteristic of food reduction. The stage‐specific interaction at intermediate food levels shows birth and death processes that control this system, and elucidates the relationship between area and food that is integral to the dynamics of patchy populations.

“…Typically, O. surinamensis larvae pass through four instars. Studies suggests that O. surinamensis populations may be regulated by cannibalism on inactive stages Evans 1989, Jacob andFleming 1989). O. surinamensis exploits temporary resources, and emigration can profoundly affect importance of cannibalism on eggs or pupae for the maintenance of declining resources (Hagstrum andGilbert 1976, van Baalen andSabelis 1995).…”
