Population growth of stored product insects on wheat containing wheat bugs

Abstract In the present study we examined effect of presence wheat bugs ( Eurygaster spp. and Aelia spp.) on mortality, progeny production infestation patterns three stored product insects, Trogoderma granarium Everts, Sitophilus oryzae (L.) Rhyzopertha dominica (F.). The bioassays were carried out under laboratory conditions (25 ± 1 °C, 60 5% relative humidity (r.h.) continuous darkness), 20 adults each insect species placed in plastic vials (3 cm diameter, 8 height) with that contained different numbers (1, 2, 3 or 5 adults). general, mortality was not affected by bugs, most combinations examined. cases, T. higher which containing , while S. also bugs. Frass for all similar, but greater frass occurred R. . Overall, could affect survival both our results showed beetle longevity fecundity can be are likely to grains after harvest. Graphical abstract
