Damage of Rough and Brown Rice by Four Stored-product Insect Species

Efficacy of ozone gas against laboratory and field strains of four stored-product insect species

The efficacy of ozone, as an alternative fumigant to phosphine, was tested against four economically important stored-product insect species at 27.2°C and 20.4% r.h. Adults of phosphine susceptible laboratory strains and phosphine resistant field strains of the red flour beetle, Tribolium castaneum (Herbst); sawtoothed grain beetle, Oryzaephilus surinamensis (L.); maize weevil, Sitophilus zeama...

Efficacy of Ozone against Phosphine Susceptible and Resistant Strains of Four Stored-Product Insect Species

The efficacy of ozone was evaluated against four economically-important stored-product insect species at 27.2 C and 20.4% r.h. Adults of phosphine-susceptible laboratory strains and phosphine-resistant field strains of the red flour beetle, Tribolium castaneum (Herbst), saw-toothed grain beetle, Oryzaephilus surinamensis (Linnaeus), maize weevil, Sitophilus zeamais Motschulsky, and rice weevil,...

Susceptibility of laboratory and field strains of four stored-product insect species to spinosad.

Two field strains of the Indianmeal moth, Plodia interpunctella (Hübner); red flour beetle, Tribolium castaneum (Herbst); and lesser grain borer, Rhyzopertha dominica (F.), and one field strain of the rusty grain beetle, Cryptolestes ferrugineus (Stephens), were collected from hard red winter wheat stored on farms in northeastern Kansas. Fifty eggs of P. interpunctella and 25 beetle adults of e...

Evolution of reproductive strategies in stored product insect species

Functional properties as affected by laboratory-scale parboiling of rough rice and brown rice.

Rough rice (RR) is the conventional feedstock for parboiling. The use of brown rice (BR) instead of RR is gaining interest because it results in shorter processing time and lower energy requirement. This study compared the functional properties of milled parboiled rice under different parboiling conditions from RR and BR. Presoaked RR and BR from cultivars Bolivar, Cheniere, Dixiebelle, and Wel...
