| Resumo: Recentemente a disseminação da lagarta Helicoverpa armigeratrouxegrande preocupação à cadeia produtiva de sojadevido aosdanos produtivos e econômicoscausados. Assim, há necessidade urgente de se obter o controle desta praga, de preferência usando processos sustentáveis. O objetivo deste trabalho foi avaliar o potencial inseticida do extrato aquoso de Tithonia diversifolia(Hemsl.) com intuito de se obter um biopesticida eficiente e com baixo risco ambiental e à saúde humana. Para isso foi realizado o bioensaio com microcrustáceos Daphnia magna, onde foi avaliada aimobilidade dos organismosem três concentrações do extrato aquoso. Este bioensaio foi selecionadopor ser mais rápido, mais simples e usar menos quantidade de extrato,quando comparado ao... |

| Brazil is internationally known for its activities in mass production and use of biocontrol agents. Batch studies on Bacillus thuringiensis fermentation were initiated in 1970, at the State University of Campinas (UNICAMP) to explore the feasibility of producing endotoxin preparations, using cheap liquid by-products as fermentation substrates. The culture media composition, its price, and their influence on the final cost were studied for mini-and pilot-scale production. The results obtained generated two industrial patents on the fermentation process, using sugar cane molasses and corn steep liquor as sources of nutrients. Besides these studies, others such as rheological characteristics of many culture media and the culture broths, the influence of... |

| Biopesticide are living microorganisms (fungi, bacteria, microsporidia and viruses), microscopic animals (nematodes) and macroorganisms (predators and parasitoids, insects and mites) or natural products derived from these organisms that are used as plant protection products. The demand for biopesticides and biocompatible products to control pests, diseases and weeds has been increasing in Brazil in recent years, with increases in concern about the environment and contamination of food with synthetic chemical pesticides. It is also important to consider the expansion of the organic farming area and lhe move towards integrated pest management (IPM) in Brazil. This artide provide an analysis and summary of the use of biopestides in Brazil, including historic... |

| Root-knot nematodes are microscopic round worms, which cause severe agricultural losses. Their attacks affect the productivity by reducing the amount and the caliber of the fruits. Chemical control is widely used, but biological control appears to be a better solution, mainly using microorganisms to reduce the quantity of pests infecting crops. Biological control is developing gradually, and with time, more products are being marketed worldwide. They can be formulated with bacteria, viruses or with filamentous fungi, which can destroy and feed on phytoparasitic nematodes. To be used by the farmers, biopesticides must be legalized by the states, which has led to the establishment of a legal framework for their use, devised by various governmental... |

| O objetivo deste trabalho foi avaliar a aplicação de óleo essencial de copaíba no controle da antracnose, nos frutos do maracujazeiro-amarelo, e comparar sua ação fungicida/fungistática in vitro com o óleo resina de copaíba. No experimento in vivo, os frutos foram inoculados com uma suspensão de esporos da ordem de 106 conídios mL-1 e 1% de Tween 80, acondicionados em bandejas de polipropileno e colocados em câmara incubadora com temperatura de 25°C e 90% de umidade relativa do ar. Passadas 24 horas da inoculação, pulverizou-se óleo essencial nas seguintes concentrações: T1= 0 mL L-1; T2= 0,25 mL L-1; T3= 0,5 mL L-1; T4= 0,75 mL L-1; T5= 1,0 mL L-1, sendo avaliados a perda de massa do fruto, a severidade da antracnose e o número de lesões, ambas aos seis... |

| ABSTRACT: The pesticide industry has undergone a diversification process led by six leading companies (Monsanto, Syngenta, Bayer, Dow, DuPont, BASF) that control roughly 68% of the world market. This growth, initiated in the second half of the 1990s, occurred through deals and acquisitions of companies from the seed and biopesticide markets. This paper analyzes these diversification strategies, which have involved a capital mobilization process based on the exploitation of economies of scope and management of complementary assets. This aims to minimize the risks of investment in consolidated markets as well as in new ones. |

| Assessing the potential environmental effects of biopesticides is an important part of its development and registration process. In Brazil little attention has been given to this approach, but now with the new approved rules for biopesticides registration that issue will be increasingly considered (COSAVE, 1997). Among the potential safety issues related to the use of microorganisms for pest control pathogenicity and toxicity effects on non-target beneficial organisms are the main concern (OECD, 1995; USEPA, 1989; Cook et al, 1996). In addition to that potential hazards there are those posed by microbial contaminants and by sybstances used in the formulation of biopesticides (e.g. stickers, carriers, spreaders, UV protectors) (Burges, 1981). Bacillus... |
