Abstract: The present invention refers to a food bait characterized in that it comprises at least: one or more food components, a preservative or a mixture of preservatives, at least one toxic ingredient and a fourth component selected between: at least one specific attractant of tephritidae insects, and at least a moisture regulator and in that said bait is in the semi-solid gel form.

Abstract: The present invention provides an emitter of semiochemical substances that comprising a support and a semiochemical subsistence adsorbed in the same, is characterized in that said support is a sepiolite and in that the retaining force between said sepiolite and said semiochemical substance is regulated in such a way that a controlled emission kinetics of said semiochemical substance is obtained. The process for the manufacture of said emitter comprises the operations of modifying a natural sepiolite and of associating it to a semiochemical substance, in such a way that the same is retained with a force such that the emitter has a controlled release kinetics of the substance. The cited emitter is especially useful in the agricultural sector, for insect plague control in crops.

Abstract: This patent presents a method to obtain supports for the controlled and lasting emission of semiochemicals used in the environmental fight against agricultural plagues, due to their noteworthy advantages over other emitters, among which the following stand out: Adaptation to the emitting needs and to the properties of each semiochemical The capacity to achieve long useful life times The non-existent pollution that they produce, due to their chemical nature, they blend in soil Their ease of application since they may be used in the form of pastilles, granulates or powder The possibility of compacting them with different shapes in order adapt them to any support.
