Viruses of Heliothis armigera (Hübner) (Lepidoptera : Noctuidae)
Heliothis armigera (the bollworm) is a pest of agricultural importance in Southern Africa. It is often simultaneously infected with several insect viruses: nuclear polyhedrosis virus (NPV), granulosis virus (GV), and cytoplasmic polyhedrosis virus (CPV). Both NPV and GV have been previously studied …

Floral derived compounds as attractants for agricultural pests in the family Noctuidae
Many species of moths within the family Noctuidae are significant agricultural pests. Specific floral volatiles are attractive to both male and female Noctuidae and may be used to as attractants in crop protection. For the first time the following research compares two types of floral volatile …

The Allatoregulatory Neuropeptides and their Genes in the fall armyworm, Spodoptera frugiperda (Lepidoptera: Noctuidae)
The genes encoding the S. frugiperda allatotropin (Spofr-AT), allatostatin (Spofr-AST), allatostatin type-A (Spofr-AST A) peptide family and allatotropin 2 (Spofr-AT 2) peptides were isolated from S. frugiperda brain cDNA. The Spofr-AT gene is expressed in three mRNA isoforms with 134, 171, and 200 …

Multiplicação de Spodoptera frugiperda multiple nucleopolyhedrovirus (SfMNPV) em lagartas de Spodoptera frugiperda (Lepidoptera: Noctuidae)
… controle de Spodoptera frugiperda (Lepidoptera: Noctuidae), porém seu uso em larga escala depende de se maximizar sua produção a partir de larvas infectadas. A temperatura adequada, o tempo de exposição ao patógeno, a idade na qual as lagartas são inoculadas com o vírus, a concentração da …

Sobrevivência, comportamento locomotor, respiração, alimentação e histologia de Spodoptera frugiperda (Lepidoptera: Noctuidae) mediados pela deltametrina
Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), praga agrícola polífaga, é controlada, principalmente, com inseticidas piretróides. A toxicidade, sobrevivência, respiração, comportamento locomotor, alimentação e histotologia do intestino médio de S. frugiperda exposta à deltametrina …

Biologia de Spodoptera frugiperda (J. E. Smith) (Lepidoptera: noctuidae) em genótipos de milho doce e comum
Spodoptera frugiperda, uma das principais pragas do milho, tem grande importância pelos danos e dificuldades de controle. A ausência de informações sobre seu impacto em milho doce motivou a comparação de sua biologia entre os genótipos ELISA, BR 400 (milho doce) e BR PAMPA (milho comum). Parcelas …

Influence of flight activity and octopamine on hemolymph trehalose titers in Heliothis zea (Boddie) (Lepidoptera: Noctuidae)
Hemolymph trehalose concentrations of male and female Heliothis zea were quantitated by high performance thin-layer chromatography (HPTLC) at various ages and times of the day and related to flight activity. Effects of octopamine injection or stress on trehalose levels were also quantified. Flight …

Rearing density effects on premigrant traits of the fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae)
Laboratory and field studies of the fall armyworm, <i>Spodoptera frugiperda</i>, were undertaken to determine if a high larval rearing density produces premigrant traits, and if these traits can be used as criteria for separating nonpremigrant from premigrant groups. An increase in larval rearing …

Campoletis flavicincta (Hym., Ichneumonidae) : ocorrência, criação e interação com Spodoptera frugiperda (Lep., Noctuidae) e Bacillus thuringiensis aizawai
Spodoptera frugiperda é um inseto-praga responsável por altos níveis de desfolhamento em gramíneas cultivadas, sendo que, dentre os métodos de controle, o biológico pode vir a tornar-se uma alternativa. Foi feita uma revisão de literatura sobre parasitóides de S. frugiperda. A ocorrência de …

The olfactory basis for attraction of the Bollworm helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae) to host-plant flowers
The objective of this work was to investigate whether or not olfactory clues play a role in host plant location by the polyphagous moth, Helicoverpa armigera. Volatiles collected from flowers of African marigold, Tagetes erecta, and sweet pea, Lathyrus odouratus, were found to elicit …

Host range and multitrophic interactions between the parasitoid Cotesia vanessae (Hymenoptera: Braconidae) and Noctuidae (Lepidoptera) hosts in North America
Caterpillars in the family Noctuidae are important crop pests. After discovering the parasitoid Cotesia vanessae in the Nearctic region, which was previously only known from the Palearctic and Afrotropic regions, I investigated its fundamental host range on North American Lepidoptera and found that …

Investigating host use and migration by the corn earworm (Noctuidae: Helicoverpa zea) using stable isotope and morphometric techniques.
The commercialization of cotton and corn, genetically engineered to produce a caterpillar-specific insecticidal protein (Bt toxin) has focused renewed attention on the issue of southward migration of Helicoverpa zea because it could have a major effect on the rate at which this pest evolves …

RNA interference with allatoregulating neuropeptide genes affecting circadian rhythm, development, mating and reproduction of Spodoptera frugiperda (Lepidoptera: Noctuidae)
Juvenile hormones (JHs) have juvenoid functions but also act as a true gonadotropin in the Lepidoptera. JHs are released by the corpora allata (CA) into the hemolymph, which are under allatotropic and allatostatic neuropeptide control as well as under somatic and environmental stimulus. Two types …

Transcriptional effects of predator cues in the brain of Spodoptera frugiperda (lepidoptera: noctuidae) moths exposed to bat ultrasound
… reported. Within several moth families, such as Noctuidae, tympanic organs for recognizing ultrasonic bat calls have evolved and facilitate the avoidance of predation via eliciting flight cessation or aerial maneuvers when stimulated by ultrasound. In this study, I exposed adult male fall …
