| ABSTRACT: The cassava (Maninhot esculenta Crantz) it is an important source of energy, it has rusticity and high yield potential, and is the base food for more than 700 million people in the world. It is considered one of the most tolerant growing crop to the insects damages, however, is a host plant about 200 species of arthropods in the American continent. In Brazil the most hazardous pests are present in the aerial part of the plant causing damages in the leaves, sprout destruction, stems and branches damages, leaves fall, depressing yield and in some cases causing plant death. Recently, the presence of mealybugs in the cassava roots and also in the leaves has been detected in States of Goiás, Minas Gerais, Bahia e Distrito Federal. The continuous... |

| ABSTRACT: The endoparasitic sedentary phytonematodes of genera Heterodera, Globodera (known as cyst nematodes, CN) and Meloidogyne (the root-knot nematodes, RKN) are major crop phytopathogens, causing estimated losses of US$ 125 billion annually in the world. These plant-parasitic nematodes share some parasitism mechanisms, which ensure host-tissue invasion and host-defense evasion. The establishment and maintenance of the sophisticated molecular plant-nematode interaction are based upon several secreted molecules that access plant cellular processes, transforming them in enlarged, multinucleate, and metabolically active feeding cells. Nematicides applications are usually expensive, inefficient and environmentally hazardous. Crop rotation, bio-control... |
