ES2875230
Volatile compounds for use in the control of pests of Oxythyrea funesta, Tropinota hirta and Tropinota squalida. The invention describes the compounds 1-octen-3-ol, nonanal, geranyl acetone, octan-2-one and hexanol for use in the control of insect pests of the species Oxythyrea funesta, Tropinota hirta and Tropinota squalida in the cultivation of the vine. The present invention describes the compounds 1-octen-3-ol, nonanal, geranyl acetone, octan-2-one and hexanol for use in the control of insect pests of the species Oxythyrea funesta, Tropinota hirta and Tropinota squalida in the cultivation of the vine. The insects Oxythyrea funesta, Tropinota hirta and Tropinota squalida are considered a pest in vines because they feed on buds, clusters in formation and tender vine shoots, also causing damage to the crop with the hooks of their legs when attached to the shoot. Different colors, traps and volatile compounds have been used as bait for the control of these insects, however, these floral compounds are often nonspecific and can also affect beneficial insects. The presented invention refers to the use of the volatile compounds 1-octen-3-ol, nonanal, geranil acetone, octan-2-one and hexanol, for the selective control of pests of these insects in vine cultivation. Among other benefits, this composition offers several advantages, allowing for a specific control of these insects without harming or affecting other beneficial insects for the plant, it also reduces the need of chemical products to control this plague, resulting in no chemical residues in the crop, avoiding damage to the environment and human health. These compounds have been tested in the field to prove their efficacy, where they have been tested against current methods with statistically significant positive results.
The main advantages of these compounds are: - It allows the specific control of the insects Oxythyrea funesta, Tropinota hirta and / or Tropinota squalida. - This specificity allows the selective capture of the pest insects, without harming or affecting other beneficial insects for the plant. - It allows the capture of females, preventing them from spreading the pest and eradicating it in a faster way. - Reduce the application of chemical synthesis products to control these insects - No chemical residues accumulate with these compounds in the crop affected by the insects, avoiding damage to the environment and human health - It conforms to the sustainable use of insecticides and/or fungicides required by the European Parliament through its Directive 2009/128 / CE - Can be used in organic farming
Problem solved by the invention:
The insects Oxythyrea funesta, Tropinota hirta and Tropinota squalida (Coleoptera: Scarabs), called tall shell insects or “flower beetles”, generally coexist with the vines without causing damage to them. However, at the time of sprouting, these insects are considered a pest because they feed on buds, clusters in formation and tender vine shoots, also causing damage to the crop with the hooks of their legs when attached to the shoots. As Oxythyrea funesta, Tropinota hirta and Tropinota squalida feed on buds and flowers, the largest field of study on these insects has been developed in floral attractant compounds with traps of different coloration. Different colors, traps and volatile compounds have been used as bait for the control of these insects, such as, for example, (±)-lavandulol and 2-phenylethanol in commercial CSALOMON® traps. However, these floral compounds are often nonspecific and can also affect beneficial insects. The same happens with other volatile compounds present in affected plants. Consequently, so far, there is no specific attractant compound for the control of Oxythyrea funesta, Tropinota hirta and Tropinota squalida in vine cultivation. Therefore, the technical problem can be posed as obtaining specific attractants for the control of pests of Oxythyrea funesta, Tropinota hirta and Tropinota squalida in vine cultivation.
Technology to solve the problem:
The presented invention refers to the use of the volatile compounds 1-octen-3-ol, nonanal, geranil acetone, octan-2-one and hexanol, for the selective control of pests of the insects Oxythyrea funesta, Tropinota hirta and / or Tropinota squalida in vine cultivation. These compounds can be used together with a trap, individually, and, also, in combination with other attractants.
