In this study, 18-38 nm-sized and spherical-shaped nanopowder Fe3O4 NPs concentrations (0.4, 2, 10, 50, 250 µg/10 µl) was force-fed to sixth instar (180 ± 20 mg) Galleria mellonella (Lepidoptera: Pyralidae) larvae under laboratory conditions. The effects of magnetic iron oxide nanoparticles (Fe3O4) on the pupal adult developmental times, weights longevity G. were recorded. Results showed that t...

The striped stem borer, Chilo suppressalis (Walker) (Lepidoptera: Pyralidae), is the most abundant stem borer of rice Oryza sativa L. (Poaceae) in temperate Asia. Chilo suppressalis also occurs throughout the tropical rice-growing areas of Asia, where it is generally second in abundance to the yellow stem borer, Scirpophaga incertulas (Walker) (Lepidoptera: Pyralidae) (Pathak & Khan, 1994). Ste...

Of approximately 18,200 ha planted to sugarcane in south Texas, only approximately 80 ha (<0.5%) are treated with insecticides because this type of control is widely regarded as ineffective against stalkboring pyralids, the key pests of sugarcane. Therefore, nonchemical control measures, such as resistant varieties and biological controls, must be evaluated to mitigate the losses caused by stal...
