3. Computer simulation applied to the biological control of the insect aphis gossypii for the parasitoid Lysiphlebus testaceipes.
In integrated pest management (IPM), biological control is one of the possible options for the prevention or remediation of an unacceptable pest activity or damage. The success of forecast models in IPM depends, among other factors, on the knowledge of temperature effect over pests and its natural enemies. In this work, we simulated the effects of parasitism

5. Agricultura de base ecológica em sistemas urbanos: potencialidades, limitações e experiências.
ABSTRACT: Urban agriculture conducted with ecological principles is an alternative to produce healthy food, but it demands planning and suitable technologies. This ecological approach must be based on crop diversity, organnic or mineral fertilizers from natural origin and control of pests and diseases by non-toxic means. Cultivation of different species is t

8. Controle hormonal da defesa à herbivoria em tomateiro / Hormonal control of herbivory defense in tomato
Even though the cultivation of tomato has a high economical importance, this culture is classified as being of elevated risk because of it common infestation by pests and diseases. This problem makes this culture greatly dependent of the application of several agrochemicals, which leads to increase in cost of production, environmental damages and also facili

9. Screening of Bacillus thuringiensis strains toxic to the cotton aphid (Aphis gossypii) / Seleção de estirpes de Bacillus thuringiensis tóxicas ao pulgão do algodoeiro (Aphis gossypii)
The production of the cotton crop is growing and exposes this culture to severe attack of various pests, including the cotton aphid (Aphis gossypii). This insect has caused 44% loss to the culture of cotton, attacking the initial stages of the crop. The continuous sucking sap deforms the shoots, hampers the development of the plant and also expels a sugar se

11. Ação inibitória de extratos de plantas do Cerrado sobre α-amilases com ênfase em Kielmeyera coriacea
α-amylases are digestive enzymes widely distributed in microrganims, plants and animals, that catalyze hidrolysis of α-1,4 glicosidic bonds and act in carbohydrate metabolism. The inhibition of α-amylases can be applied on control of insect pests that depends on starch-rich diet to energy production, reducing the amount of nutrients to avoid i
