A computer model for simulating population dynamics of Lyctocoris campestris (F.), a predator of stored-product insects, was developed using data from the literature and newly collected data for adult longevity and fecundity. Immature development time and survival, adult longevity, fecundity, and cannibalism were simulated. The model was validated at ambient environmental conditions during thre...

Insects of the family Dermestidae are common insect pests of museums and other sites where historical artifacts are displayed and stored. Trogoderma variabile (Ballion), the warehouse beetle, is a member of this family, and though it is more commonly associated with processed and finished stored food products, it can be found in museums. There are aspects relating to monitoring and control of T...

The almond moth, Cadra cautella (Walker), is a common storage pest known to infest a wide range of dried plant materials, and it has been recorded from a warehouse in Florida during storage of dried passion-flower ( Passiflora incarnata L.) and dried saw palmetto berries Serenoa repens (Bartram) Small. Its status as a pest of stored saw palmetto was confirmed by trapping in a second warehouse u...

The efficacy of low temperatures ranging from 0 to −15 °C was evaluated against all life stages Tribolium confusum, adults Oryzaephilus surinamensis and Liposcelis bostrychophila. All species/life were exposed in empty vials or containing 5 g flour, for time intervals 2–7 d. Eggs pupae the least susceptible T. as these had highest survival at – 15 °C. Nevertheless, this temperature, an exposure...

We carried out trials on the commercial applications of nitrogen in different industrial structures, using phosphine-susceptible and -resistant populations three stored product beetle species, red flour beetle, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae), rice weevil, Sitophilus oryzae (L.) Curculionidae), saw-toothed grain Oryzaephilus surinamensis Silvanidae). Twelve were conduct...
