Larvae of the Southern pine coneworm, Diorycha amateella (Hulst) (Lepidoptera: Pyralidae), were collected monthly during the growing seasons of 1996 and 1997 from loblolly pine, Pinus taeda L., seed orchards in Alabama, Florida, Georgia, South Carolina, and Virginia, and examined for pathogenic microorganisms. One fungus, Beauueria bassiana (Bals.) Vuill, a granulosis virus (Baculoviridae: Euba...

Cnaphalocrocis medinalis Güenée can cause severe losses in rice. Cytochrome P450s play crucial roles in the metabolism of allelochemicals in herbivorous insects. Two novel P450 cDNAs, CYP6CV1 and CYP9A38, were cloned from the midgut of C. medinalis. CYP6CV1 encodes a protein of 500 amino acid residues, while CYP9A38-predicted protein has 531 amino acid residues. Both cDNA-predicted proteins con...

The Indianmeal moth, Plodia interpunctella Hübner (Lepidoptera: Pyralidae), is a major stored product pest that is found throughout the world. In this study, the effect of oral exposure to Bacillus thuringiensis (Berliner) subsp. kurstaki (Bacillales: Bacillaceae) and azadirachtin was evaluated in third instar P. interpunctella under laboratory conditions. The median lethal concentration (LC50)...

in the course of study on larval parasitoids of carob moth, ectomyelois ceratoniae zeller (lep.: pyralidae), an hyperparasitoid wasp, pachycrepoideus vindemmiae rondani, was collected from pupae of apanteles sp. (hym.: braconidae). the latter species is the larval parasitoid of the carob moth. the p. vindemmiae belongs to the family pteromalidae and is a new record for iran insect fauna.

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...
