13. Proposta de um protocolo para avaliação da viabilidade de conídios de fungos entomopatogênicos e determinação da proteção ao calor conferida a Beauveria bassiana e Metarhizium anisopliae pela formulação em óleo emulsionável / Establishment of a protocol to evaluate the conidial viability of entomopathogenic fungi and determination of heat protection to Beauveria bassiana and Metarhizium anisopliae by emulsifiable oil formulation
This study aimed to evaluate, under laboratory conditions, the influence of temperature and exposure time on the viability and virulence of Beauveria bassiana and Metarhizium anisopliae in suspensions prepared with pure conidia, rice plus fungus and in formulations of wettable powder and concentrated suspension in emulsifiable oil. Initially, an efficient an

15. Engineering Bacillus thuringiensis bioinsecticides with an indigenous site-specific recombination system.
The cry genes of Bacillus thuringiensis encode a diverse group of crystal-forming proteins that exhibit insecticidal activity, particularly against the larvae of lepidopteran, coleopteran, and dipteran insects. The efficacy of B. thuringiensis-based biopesticides may be improved through the genetic manipulation of these genes. A gene transfer system has been

16. Characterization of Cell Lysis in Pseudomonas putida Induced upon Expression of Heterologous Killing Genes
Active biological containment systems are based on the controlled expression of killing genes. These systems are of interest for the Pseudomonadaceae because of the potential applications of these microbes as bioremediation agents and biopesticides. The physiological effects that lead to cell death upon the induction of expression of two different heterologo

17. One gene in diamondback moth confers resistance to four Bacillus thuringiensis toxins
Environmentally benign insecticides derived from the soil bacterium Bacillus thuringiensis (Bt) are the most widely used biopesticides, but their success will be short-lived if pests quickly adapt to them. The risk of evolution of resistance by pests has increased, because transgenic crops producing insecticidal proteins from Bt are being grown commercially.

18. Ecological approaches and the development of “truly integrated” pest management
Recent predictions of growth in human populations and food supply suggest that there will be a need to substantially increase food production in the near future. One possible approach to meeting this demand, at least in part, is the control of pests and diseases, which currently cause a 30–40% loss in available crop production. In recent years, strate
