Brain-independent development in the moth Sesamia nonagrioides

Journal of Insect Physiology, 2010
The caterpillars of Sesamia nonagrioides developing under long-day (LD) photoperiod pupate in the 5th or 6th instar whereas under short day (SD) conditions they enter diapause and undergo several extra larval molts. The diapause is terminated within 1-3 instars upon transfer of SD larvae to the LD conditions.

Response of Mythimna unipuncta Males to Components of the Sesamia nonagrioides Pheromone

Journal of Chemical Ecology, 2009
Several sympatric lepidopteran species feed on maize plants, and the different components of their species-specific female sex pheromones may play a role in attracting conspecifics and/or deter heterospecific males. In this study, we analyzed the content of Mythimna unipuncta pheromone glands and tested the response of males to components of their own ...

Phenological Model forSesamia nonagrioides(Lepidoptera: Noctuidae)

Environmental Entomology, 2001
Abstract The development time of different stages of Sesamia nonagrioides Lefevbre was studied in the laboratory at constant temperatures in the range 10–36°C. The relationship between the developmental rate (1/d) and the temperature (°C) was determined using both linear and nonlinear (Logan type III) models.

Juvenile hormone and diapause in the Mediterranean corn borer, Sesamia nonagrioides

Journal of Insect Physiology, 1998
Juvenile hormone content of Sesamia nonagrioides larvae reared under different environmental conditions that induce diapause was studied using a bioassay on newly-emerged Tribolium confusum pupae. Two analytical methods were also used to measure JHIII content. Extracts from larvae that developed under different conditions of photoperiod and temperature

2010
Sesamia nonagrioides (Lef bvre) (Lepidoptera: Noctuidae) is a serious pest of wild and cultivated plants with particular preference in maize and sweet sorghum. In the present study, laboratory experiments were conducted to investigate the oviposition preference among cultivated and wild host plants.

Μελέτη θερμοεπαγωγής και βιολογικών ρολογιών στο έντομο Sesamia nonagrioides (Lepidoptera: Noctuidae)

2021
Η διάπαυση των εντόμων είναι μια περίοδος περιορισμού της ανάπτυξης που κατευθύνεται από αλλαγές σε αβιοτικά μηνύματα, τα οποία δείχνουν αλλαγές σε περιβαλλοντικές συνθήκες, όπως είναι ο χειμώνας. Κατά τη διάρκεια της διάπαυσης, πολλά γονίδια δεν εκφράζονται, ενώ κάποια άλλα εκφράζονται και φαίνεται ότι αυτά σχετίζονται με ωρολογιακούς μηχανισμούς και ...

Effects of Sublethal Concentrations of Bacillus thuringiensis on Larval Development of Sesamia nonagrioides

Journal of Economic Entomology, 2005
In the Mediterranean Basin, developed diapausing larvae of the borer Sesamia nonagrioides Lefèbvre are found consistently during autumn in transgenic corn, Zea mays L., expressing Bacillus thuringiensis Berliner (Bt) toxins derived from event 176. These larvae can feed on sublethal concentrations of Bt toxins because the expression of this corn toxin ...

Dispersal capacity in the Mediterranean corn borer, Sesamia nonagrioides

Entomologia Experimentalis et Applicata, 2004
AbstractCorn (Zea mays L.) borers are the primary target of Bacillus thuringiensis Berliner (Bt) transgenic maize. Management of corn borer resistance to Bt requires information on larval and adult dispersal capacities, a feature that is particularly unknown in Sesamia nonagrioides Lefèbvre (Lepidoptera: Noctuidae), the most damaging corn borer in ...
