Ano: 2009 URL: http://hdl.handle.net/10521/1352 Discovery and development of biological agents to control crop pests Neotropical Entomology Slininger,Patricia J.; Behle,Robert W.; Jackson,Mark A.; Schisler,David A.. Thousands of potential microbial biocontrol agents have been isolated from agricultural fields and crops during research over the last 80 years, yet only a few are in commercial use. Recently, public health and safety concerns about the environmental impact of chemical pesticides have led to consideration of biological control as a natural approach to maintaining crop health. Despite environmental incentives and strong research efforts, commercialization of biocontrol agents has been slow to evolve. The momentum of the chemical industry is difficult to shift, and fermentation processes tend to be more expensive to operate than synthetic chemical processes.Yet there is a demand for biological control products, especially in agricultural niche markets, where...

Diatraea saccharalis Fabr. (Lepidoptera: Crambidae) is a major sugarcane pest in Brazil. The management of infested areas is based on the release of Cotesia flavipes (Cameron) (Hymenoptera: Braconidae), a parasitoid of D. saccharalis larvae, but there are doubts about the effectiveness of C. flavipes, primarily regarding its rate of dispersal in sugarcane fields. Thus, the objective of this study was to evaluate the dispersal of C. flavipes in a sugarcane field and suggest a release method that provides higher parasitoid efficiency. The study was carried out in four areas of approximately 1 ha, in which stalk pieces containing 20 D. saccharalis larvae were distributed in a rectangular grid, and 12,000 C. flavipes adults were released at four points, that...

Bras. entomol. Duque L,Jonny E.; Navarro-Silva,Mario Antônio. The dynamics of the control of Aedes (Stegomyia) aegypti Linnaeus, (Diptera, Culicidae) by Bacillus thuringiensis var israelensis has been related with the temperature, density and concentration of the insecticide. A mathematical model for biological control of Aedes aegypti with Bacillus thuringiensis var israelensis (Bti) was constructed by using data from the literature regarding the biology of the vector. The life cycle was described by differential equations. Lethal concentrations (LC50 and LC95) of Bti were determined in the laboratory under different experimental conditions. Temperature, colony, larvae density and bioinsecticide concentration presented marked differences in the analysis of the whole set of variables; although when analyzed...

Ano: 2006 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0085-56262006000400014 Ecological engineering: a new direction for agricultural pest management AgEcon Gurr, Geoff M.; Wratten, Steve D.; Altieri, Miguel A.. Ecological engineering has recently emerged as a paradigm for considering pest management approaches that are based on cultural practices and informed by ecological knowledge rather than on high technology approaches such as synthetic pesticides and genetically engineered crops (Gurr et al. 2004a). This article provides a brief summary of ecological engineering for arthropod pest management and contrasts it with its controversial cousin, genetic engineering. The development of ecological engineering is explored, ranging from a simple first approximation that diversity is beneficial, to contemporary understanding that diversity can have adverse effects on pest management. This requires that the functional mechanisms that lead components of biodiversity to...
