Understanding the structure and function of Bacillus thuringiensis toxins
(Pergamon-Elsevier Science Ltd, 2016-01)
As biological control agents take an expanding share of the pesticides market and the production of insect-resistant crops increases, it is essential to understand the structure and function of the active agents, the ...
Interactions of Bacillus thuringiensis strains for Plutella xylostella (L.) (Lepidoptera: Plutellidae) susceptibility
(2019-11-01)
Bacillus thuringiensis (Bt) biopesticides are an environmentally safe alternative to the management of Plutella xylostella pesticide resistance evolution. We evaluated P. xylostella susceptibility to six Bt strains cultivated ...
Survival and nutritional indexes of Spodoptera frugiperda (J.E. Smith, 1797) (Lepidoptera: Noctuidae) maintained in Bt maize for five generations
(Univ Federal Rural Pernambuco, 2019-01-01)
The selection pressure generated by the incorrect use of Bt maize might result in Spodoptera frugiperda individuals resistant to the toxins synthesized by the plant. In this study was evaluated the nutritional parameters ...
Toxicidade letal e subletal de toxinas e plantas Bt a Spodoptera eridaniaToxicity lethal and sublethal of Bt toxins and plants to Spodoptera eridania

Botulinum toxin type A inrefractory chronic migraine: an open-label trial
(Associação Arquivos de Neuro-Psiquiatria Dr. Oswaldo Lange, 2007)
Botulinum toxin type A (BT-A) has been described as an important strategy to various types of pain such as cervical dystonia, myofascial pain syndrome and headache. Although BT-A efficacy has not been proven in tension ...
Botulinum toxin as a treatment for short bowel syndrome in rats
(Sociedade Brasileira para o Desenvolvimento da Pesquisa em Cirurgia, 2019)
AbstractPurpose: The denervation of the intestine with benzalkonium chloride (BAC) reduces mortality and improves weight gain in rats with short bowel syndrome (SBS). Nevertheless, translating these promising findings from ...
Avaliação da interação tritrófica de Soja Bt, Spodoptera eridania (Lepidoptera: Noctuidae) e Dolichozele sp. (Hymenoptera: Braconidae)
(Universidade do Vale do Rio dos Sinos, 2017-07-31)
The development of insect resistance poses a threat to pest control using Bt plants. The conservation of natural enemies may contribute to reduce the evolution of Bt soybean resistance. Among the insects of interest for ...

Insect/Bt-cotton interactions: Are immunological variables and hemocyte ultrastructure in Podisus nigrispinus (Hemiptera: Pentatomidae) affected?
(2013-04-01)
Recent studies have shown that ingestion by the army worm Spodoptera frugiperda of Cry1Ac toxin from Bt cotton promotes histochemical and ultrastructural changes in the digestive cells of the predatory pentatomid bug Podisus ...
