“…The larvae of S. cerealella attack a variety of kernels, such as corn, barley, sorghum, wheat, soybean, rice, paddy and other stored cereal grain. Further, S. cerelella can also attack on the stored spices such as piper, Coriander, ginger, turmeric and many other non crop wild plants (Dakshinamurth & Regupathy, 1988;Ukeh et al, 2008;Pan et al, 2008;Ashamo, 2010;Trematerra et al, 2011;Trematerra, 2015). In case of store wheat grain, Khan et al (2010) reported that about 12 wheat genotypes were damaged by S. cerelella and it causes annually 19.2-58.2% dame and 12.19 -40.93% losses.…”

This study was conducted under laboratory conditions to find out the effect of the non-catalytic infrared on the mortality rates and development of various stages of the grain moth Sitotroga cerealella. Result of the study revealed that treated eggs, first and fourth instars, pupae and adults mortality increased by increasing non-catalytic infrared waves exposure time from 40 and 60 seconds at 40 and 50 ο C. Highest egg mortality (56.7%) and hatching period (6.1 days) was reported on the exposure of 60 seconds at 50 ο C while the lowest values 3.3% and 4.5 days respectively was reported for the control treatments. Similar conditions were reported for the first and fourth instars, pupae and adults mortality. Infrared waves exposure for 60 seconds at 50 ο C significantly influenced the development of S. cerealella and showed 53.31% first stage larval mortality, 50% fourth stage larval mortality, 46.7% pupal mortality and 66.7% adult mortality. Furthermore, it was reported that infrared wave did not have any negative effect on the seed germination and 60 second exposure at 50 ο C showed 96 percent seeds germination.

“…Sitophilus spp. or Rhyzopertha dominica (F.)) from external feeding pests (Table 1) because grain infested by internal feeding primary pest is refused or penalised by mills and commodity traders; these pests are the main source of fragments in processed flour (Trematerra et al 2011). Therefore, in many cases, farmers fumigate only when primary internal feeding pests are present (e.g.…”

Sci., 52: 45-53.Pitfall trapping studies are available for particular stored grain pest species. In small farms, the stored grain pest control strategy is rarely species-specific but is often "pest ecological-group-specific" instead. A two-year field study was conducted in flat grain stores to compare the efficacy of cone-surface (PC trap; AgriSense-BCS Ltd., Pontypridd, UK) and probe-subsurface (WB Probe II Trap; Trécé Inc., Adair, USA) traps for three ecological insect pest groups (Group I, internal feeding primary pests; Group II, external feeding primary pests; Group III, external feeding secondary pests). Altogether, 1328 specimens (32% Group I, 11% Group II, and 57% Group III) in 12 species of Coleoptera (17% Group I, 25% Group II, and 58% Group III) were trapped. No significant differences were found in the efficacy of PC traps and WB Probe II Traps to catch the evaluated ecological pest groups over the long term. Our study indicated that for trends to appear in long-term trapping there was no need for the simultaneous use of both traps due to the low trapping differences between the surface and subsurface types of traps in all ecological pest groups. However, significant differences between the traps were found in the short-term evaluations and before and after fumigation; in that case, the use of both traps is recommended because of the higher sensitivity and more precise evaluation of efficacy of the control treatment effects.

“…There is increasing evidence that pests may be frequent contaminators of flour and cereal products (Stejskal & Hubert 2008;Trematerra et al 2011;, 2015Stejskal et al 2014a). Food safety is one of the most important political priorities in the EU.…”

Aulicky R., Stejskal V., Dlouhy M., Liskova J. (2015): Validation of hydrogen cyanide fumigation in flourmills to control the confused flour beetle. Czech J. Food Sci., 33: 174-179.In the milling industry, the Tribolium confusum is hard to exterminate pest. We measured the concentration time product (Ct-P) achieved during the hydrogen cyanide (HCN) fumigation and examined whether the Ct-P levels in the explored Czech pilot mill were sufficient to control the field strain of T. confusum. Using an originally constructed, gastight fumigation chamber, it was estimated that the Ct-P required for the complete killing of the field strain of T. confusum was 4× higher (4.35 g/h/m 3 ) than the levels required to kill the laboratory strain (1.25 g/h/m 3 ). The Ct-P levels (ranging from 79 g/h/m 3 to 100 g/h/m 3 ) reached during the mill fumigations with HCN were less than half of the labelled HCN rate (240 g/h/m 3 ). Nevertheless, the current HCN dosage is still sufficient since the Ct-P reached during the mill fumigations was at least 99× higher than that required for the exterminating to the lab strain and 18× higher than that required for the field strain extermination. These results were confirmed in mill validation testing, where 100% mortality of T. confusum adults was achieved.
