The cabbage moth or the sorrel moth (Lepidoptera: Noctuidae)? [PDF]

European Journal of Entomology, 2016
When insect herbivores develop over many generations on the same plant species, their descendants may evolve physiological adaptations that enable them to develop more successfully on that plant species than naïve conspecifics. Here, we compared development of wild and lab-reared caterpillars of the cabbage moth, Mamestra brassicae, on a cultivar of ...

Preventative insecticides reduce seedling injury, but do not increase yield in Bt and non‐Bt corn grown in the mid‐Atlantic

Pest Management Science, EarlyView.
Bacillus thuringiensis (Bt) traits, neonicotinoid seed treatments (NSTs), and in‐furrow pyrethroids (IFPs) can control insect pests of corn, but their target spectrum may be redundant and/or mismatch Mid‐Atlantic pest pressure. Across 9 site‐years insecticide treatments reduced pest damage and sometimes increased plant stand, but never improved yield ...

Studies on Resistance to Vegetative (Vip3A) and Crystal (Cry1A) Insecticidal Toxins of Bacillus thuringiensis in Heliothis virescens (Fabricius) [PDF]

, 2009
Bacillus thuringiensis (Bt) toxins expressed in commercial transgenic crop varieties are all δ-endotoxins (Cry toxins) but the identification of novel vegetative insecticidal proteins (Vip toxins) has extended the range of insecticidal proteins derived

Evaluation of GS‐omega/kappa‐Hxtx‐Hv1a and Bt toxins against Bt‐resistant and ‐susceptible strains of Helicoverpa zea (Boddie) and Spodoptera frugiperda (J.E. Smith)

Pest Management Science, EarlyView.
The addition of 10 μg cm−2 of Cry1Ac to the surface of GS‐omega/kappa‐Hxtx‐Hv1a (ω/κ‐Hv1a) incorporated diet can significantly increase the mortality of Cry‐resistant Helicoverpa zea compared to diets without the Cry1Ac toxin. Abstract BACKGROUND Helicoverpa zea and Spodoptera frugiperda are destructive insect pests of cotton and corn.
