Abstract


Diabrotica speciosa is a very important pest throughout Latin America, which management strategies are restrict to chemical control. We revise the usage of baits, containing semiochemicals, as management strategy for Diabrotica spp. Initially, we described the importance of baits for several orders of agricultural importance. The cucurbitacins are basic elements for Diabrotica spp. baits. These chemicals occur in some botanical families, especially Cucurbitaceae. The Carbamate insecticide Carbaril showed the best results for addition in the baits. Flowers volatile substances and pheromones also may be added to the baits to enhance attraction. Commercial baits are available for north-American species. For bait development is necessary to establish plant adherent formulations that promote the control during some weeks. We found in the literature that starch matrix may be suitable for this proposal.
