Effects of Bacillus thuringiensis Nuclear-Polyhedrosis Virus Mixtures on Trichoplusia ni Larvae
TLDR
Results from experiments in which larvae were stressed by exposure to NPV for 24-96 hr prior to exposure to B. thuringiensis showed that increased mortality was an additive effect of the two pathogens.About:

Journal ArticleDOI
Evaluation of synergism among bacillus thuringiensis toxins
TL;DR: A simple test for synergism among toxins is described and applied to previously reported data on independent and joint toxicities of insecticidal proteins from Bacillus thuringiensis, showing synergism between a 27-kDa (CytA) toxin and 130- or 65- kDa (CryIV) toxins from B. thuringienis subsp.

Synergism of entomopathogenic nematodes and imidacloprid against white grubs: Greenhouse and field evaluation
Albrecht M. Koppenhöfer,Ian Brown,Randy Gaugler,Parwinder S. Grewal,Harry K. Kaya,Michael G. Klein +5 more
TL;DR: The combination of nematode species and imidacloprid could be used for curative treatments of white grub infestations, especially against scarab species that are less susceptible to nematodes and/or imidcloprid, and the possible roles of these combinations in augmentative control approaches are discussed.

Toxicity of Bacillus thuringiensis Spore and Crystal Protein to Resistant Diamondback Moth (Plutella xylostella).
Juliet D. Tang,Anthony M. Shelton,J. Van Rie,S De Roeck,William J. Moar,Richard T. Roush,M Peferoen +6 more
TL;DR: A colony of Plutella xylostella from crucifer fields in Florida was used in mortality bioassays and revealed high levels of field-evolved resistance to HD-1 spore and all CryIA protoxins and no resistance to CryIB, CryIC, or CryID.
Journal ArticleDOI
Combined use of entomopathogenic nematodes and Metarhizium anisopliae as a new approach for black vine weevil, Otiorhynchus sulcatus , control
TL;DR: The interactions observed suggest that EPN and M. anisopliae work together synergistically in potted Euonymus fortunei Blondy (Celastraceae) under greenhouse conditions and may provide a powerful and economically feasible approach for black vine weevil larval control.
Journal ArticleDOI
Zinc and cadmium hyperaccumulation act as deterrents towards specialist herbivores and impede the performance of a generalist herbivore.
TL;DR: Metal hyperaccumulation protects plants from herbivory resulting from deterrence and toxicity against a wide range of herbivores, and the combination of metals exacerbates toxicity through joint effects and enhances elemental defence.

Journal ArticleDOI
A method of computing the effectiveness of an insecticide
TL;DR: In order to make experimental studies comparable and statistically meaningful, the article recommends the following formula: per cent control = 100(X - Y)/X, which eliminates errors due to deaths in the control sample which were not due to the insecticide.

Insecticidal activity of HD-1, a new isolate of Bacillus thuringiensis var. alesti.
TL;DR: Preparations from fermentation beers of HD-1, a new isolate of Bacillus thuringiensis var.
Journal ArticleDOI
Control of the Cabbage looper and the Imported Cabbage worm by Viruses and Bacteria
TL;DR: The combination of viruses with chemical insecticides in the spray program was especially effective and experimental formulations of B. thuringiensis (Thuricide HP® and Dipel HD-l®) were more effective than the Thuricide 90TS formulation.

Aerial Applications of a Nucleopolyhedrosis Virus and Bacillus thuringiensis Against the Douglas Fir Tussock Moth
TL;DR: Application of a nucleopolyhedrosis virus and Dipel formulated in BioFilm® against Orgyia pseudotsugata failed to reduce larval densities to a satisfactory level or to prevent severe defoliation.
