Fall armyworm, Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), infestations in most of North America arise from annual migrations of populations that overwinter in southern Texas and Florida. Cytochrome oxidase I haplotype profiles within the fall armyworm corn strain, the subgroup that preferentially infests corn (Zea mays L.), can differentiate the Texas and Florida populations....

The heritability, stability, and fitness costs in a Cry1Ac-resistant Helicoverpa zea (Boddie) (Lepidoptera: Noctuidae) colony (AR) were measured in the laboratory. In response to selection, heritability values for AR increased in generations 4-7 and decreased in generations 11-19. AR had significantly increased pupal mortality, a male-biased sex ratio, and lower mating success compared with the...

A new species of Ogdoconta Butler (Lepidoptera, Noctuidae, Condicinae, Condicini) is described from the Patagonia Mountains, Santa Cruz County, Arizona, USA. Ogdoconta margareta sp. n., is related closely to Ogdoconta tacna (Barnes) from Texas. Modifications are proposed to a recently published key to the Ogdoconta species north of Mexico to allow identification of the new species.

Achaemenothrombium cyrusi gen. et sp. nov. (Acari, Prostigmata: Trombidioidea) is described and illustrated from larvae ectoparasitic on Catocala sp. (Lepidoptera: Noctuidae) from Tehran, Iran and Achaemenothrombium talebii (Karimi Irvanlou & Kamali, 2001) comb. nov. is redescribed. A new family, Achaemenothrombiidae is proposed for accommodating this genus. A key to families of larval Trombidi...

The list of subfamily Catocalinae (Lepidoptera; Noctuidae)of Iran is updated.  Until now, 111 species belonging to 22 genera of this subfamily are recorded. Also, the Iranian records in different provinces are presented.

-The optimization of assay conditions for glutathione S-transferase and epoxide hydrolase activities in the cabbage looper (Trichoplusia ni [Hiibner], Lepidoptera; Noctuidae) using trans and cis-stilbene oxides as substrates are reported. Glutathione S-transferase activity was predominantly cytosolic, and it was much greater in the fat body than the midgut. Differences in pH optima and rates of...

A new species of the New World genus Lespesia, Lespesia melloi SP NOV: (Diptera: Tachinidae), is described from southeastern Brazil. The species is reported here as a parasitoid of Xanthopastis timais (Cramer, 1782) (Lepidoptera: Noctuidae). The caterpillars of this noctuid feed on leaves and bulbs of amaryllis (Amaryllidaceae) in Brazil.

Eight Erebidae and Noctuidae species are reported for the first time from Korea. The taxonomic positions of another two formerly misidentified species, Abrostola korbi and Diachrysia witti, are discussed. The Korean species of the Bryoleuca granitalis species-group are characterised and a new species of the group, Bryoleuca volodia sp. n. from Vietnam, is described and illustrated.

Achaemenothrombium dariusi Saboori, Wohltmann & Hakimitabar sp. nov. (Acari, Prostigmata: Trombidioidea) is described and illustrated from larvae ectoparasitic on Euxoafallax (Eversmann) (Lepidoptera: Noctuidae) from Sirch and Cheshmeh Bondar, Kerman province, Iran. It is the third species of this genus, which is recorded only from Iran. The status of this small family is discussed and a key to...

The genus Metecia Snellen (Noctuidae. Noctuinae) from Southern Argentina and Chile is redescribed and three species are recognized: M. cornifrons Snellen, M. lacustris (Köhler) n. comb., and M. hypothetica (Köhler) n. comb. In addition, Euxoa pampeana Köhler is synonymized with Metecia cornifrons. Adults and male and female genitalia are described and illustrated for the first time, and a key t...
