The present invention relates to the control of infestation of pests by inhibiting or reducing the expression of genes of the family of chitin synthase. The invention further provides methods and compositions for controlling pests by feeding them with one or more double-strand RNA molecules provides by the present invention. The invention further describes a method of obtaining transgenic plants that express double-strand RNA molecules. The present invention is preferably used for cotton-plants.

Genetic control method and compositions against insect pests in cotton plants by the silencing of genes of the laccase family

The present application relates generically to compositions used for controlling agricultural pests and, in a particular, to compositions usable for combating nematodes. The application presents a feasible alternative to the use of nematotoxic compounds that are harmful to the environment and that may damage human health. This alternative includes a nematotoxic composition for controlling nematodes that may be used on plants, parts of plants and on the soil. The respective technology results from unexpected results achieved from experiments carried out with extracts of the plant, resulting in an unheard-of nematotoxic composition comprising a specific combination of substances that are naturally found in the extract and that act synergistically.

Nematotoxic composition of synergistic effect, use of a nematotoxic composition of synergistic effect

Method and compositions for the genetic control of insect pests in cotton plants by chitin synthase gene silencing

The present invention relates generically to compositions used for controlling agricultural pests and, in a particular embodiment, to compositions usable for combating nematodes. The invention presents a feasible alternative to the use of nematotoxic compounds that are harmful to the environment and that may damage human health. This alternative is embodied through a nematotoxic composition for controlling nematodes and that may be used on plants, parts of plants and on the soil. The respective technology results from unexpected results achieved from experiments carried out with extracts of the plant, resulting in an unheard-of nematotoxic composition comprising a specific combination of substances that are naturally found in the extract and that act synergistically.
