The first findings on rusty grain beetle, Cryptolestes ferrugineus (Stephens, 1831) (Coleoptera, Cucujoidea: Laemophloeidae) in pistachio orchard in Siirt province (Turkey)

Genetic characterization of field-evolved resistance to phosphine in the rusty grain beetle, Cryptolestes ferrugineus (Laemophloeidae: Coleoptera).

Inheritance of resistance to phosphine fumigant was investigated in three field-collected strains of rusty grain beetle, Cryptolestes ferrugineus, Susceptible (S-strain), Weakly Resistant (Weak-R) and Strongly Resistant (Strong-R). The strains were purified for susceptibility, weak resistance and strong resistance to phosphine, respectively, to ensure homozygosity of resistance genotype. Crosse...

Vertical movement of adult rusty grain beetles, Cryptolestes ferrugineus, in stored corn and wheat at uniform moisture content

Vertical movement and distribution of Cryptolestes ferrugineus (Coleoptera: Laemophloeidae) adults in stored wheat and corn were studied in small (0.1 x 0.1 x 1 m) and large (0.6 m diameter and 1.12 m high) columns. The adults were introduced at the top, middle, and bottom of the small columns with a uniform moisture content (wheat: 14.5 +/- 0.1%, corn 13.5 +/- 0.1%, 15.5 +/- 0.1%, and 17.5 +/-...

Naturally Occurring Entomopathogenic Fungi Infecting Stored Grain Insect Species in Punjab, Pakistan

The occurrence of entomopathogenic fungi isolated from stored grain insect pests sampled from various geographical regions of Punjab, Pakistan, was investigated. In total, 25,720 insects from six different species were evaluated, and 195 isolates from 24 different fungal species were recovered. These included the Ascomycetes Beauveria bassiana sensu lato (Balsamo) Vuillemin (Hypocreales: Clavic...

Mortality Resulting from Interactions Between the Red Flour Beetle and the Rusty Grain Beetle

Efficacy of Pea Protein and Combinations of Pea Protein and Wasps Against Stored-Grain Insects in Large Scale Tests

Protein-enriched pea flour is toxic and repellent to three major stored grain pests, the rice weevil, Sitophilus oryzae (L.), the red flour beetle, Tribolium castaneum (Herbst) and rusty grain beetle, Cryptolestes ferrugineus (Stephens). A unique and valuable aspect of the protein-enriched pea flour is that it is not toxic several parasitoids that are associated with two of these insect pests. ...
