Definitions
- the present invention is framed in the technical sector of pest control, in particular the present invention refers to the biorational control of cocoid insect pests (Order Hemiptera, Coccoidea Superfamily).
- the cocoido or scale insects are one of the most difficult pests to handle. They are sucking insects that attack a wide range of plant species including crops of economic importance. To date, approximately 7,800 species of scales distributed in 49 families have been described (Garc ⁇ a-Morales et al ScaleNet: Scale insects (Coccoidea) database (http://scalenet.info) 2016). However, the armed scales (Family Diaspididae), the soft scales (Family Coccidae) and the woodlice (Family Pseudococcidae) constitute a considerable group of agricultural pests that generate, even at low densities of infestation, serious problems and high economic losses.
- biorational methods such as growth regulators, biological control agents and semiochemicals, among which sexual pheromones stand out.
- Growth regulators include substances such as: azadirachtin, buprofezin, phenoxycarb and / or pyriproxyfen, which have low toxicity to vertebrates, but can be harmful to both natural parasitoid enemies (Rothwangl et al. Journal of Economic Entomology 2004, 97, 1239-1244) as for beneficial arthropods (Fourrier et al PLoS One 2015, 10 (7), e0132985).
- Biological control agents that is, parasitoids and predators of cocoid or scale insects, are considered the preferred means of defense from the ecological point of view. However, to date this type of method has not been shown to be able to provide, on its own, an acceptable control of the populations of these insects, nor to keep them below the pest threshold.
- sex pheromones are chemical compounds emitted, generally, by the female in order to attract males for mating. These semiochemicals are specific to each species, are biodegradable, do not affect beneficial insects and favor natural biological balance.
- sex pheromones of 26 species of scale insects have been identified: 7 species of the family Diaspididae, 3 species of the family Margarodidae and 16 species of the family Pseudococcidae (Zou et al Natural Product Reports 2015, 32,1067- 11 13; Tabata et al Journal of Chemical Ecology 2016, 42, 1193-1200; Tabata et al Journal of The Royal Society Interface 2017, 14, 20170027).
- sex pheromones In the particular case of the insects of the Coccoidea superfamily, the use of sex pheromones is mainly aimed at the detection and monitoring of populations, and only in In the case of two species, Aonidiella aurantii Maskell (Scalebur®, Ecology and Agricultural Protection, Valencia) and Planococcus ficus Signoret (CheckMate® VMB-XL, Suterra, Bend, USA), sexual pheromone diffusers are commercialized for their control using the technique of sexual confusion.
- Aonidiella aurantii Maskell Scalebur®, Ecology and Agricultural Protection, Valencia
- Planococcus ficus Signoret CheckMate® VMB-XL, Suterra, Bend, USA
- triatomines are sensitive to carbon dioxide only at the beginning of the night, when they leave their shelters to feed themselves and the pheromones of aggregation at dawn, when they return to their shelters (Bodin et al Journal of Insect Physiology 2008, 54, 1343-1348).
- species of the Coccoidea superfamily by placing a source of sexual pheromone emission within the natural semiochemical matrix, only catches of males are observed in a certain daily time slot (Levi-Zada et al Naturwissenschaften 2014, 101, 671-678).
- the response or behavior of the males of the Coccoidea superfamily within the entangled semiochemical matrix can constitute a complex system with emergent properties (Ritter-Ortiz et al Globalization 2011, rcci.net/globalization), which is conditioned by stimuli or diverse codes (olfactory response, sensory adaptation, communication mechanism, learning, behavior, male longevity, sexual activity of males, toxicity of different substances, etc.) that may be known or not.
- the present invention solves the problems described in the state of the art by the preparation of an artificial semiochemical matrix, within the complex adaptive systems that make up the societies or colonies of cocoid insects, which makes it possible to optimize the effective flow rate of at least one semiochemical that implies the drastic reduction of the use of sexual pheromone per hectare, applying in this way a biorational control of these pests in an economically viable way.
- the present invention relates to a method for determining the effective flow rate for the effective control of at least one pest of cocoid insects comprising the following steps:

- v. at least one block comprising m diffusers of said at least semiochemical with an emission flux equal to effective flow 1 of stage b), combined with a male insect capture device, where m is the number of diffusers, being m greater or equal to 1,
- At least one block comprising m diffusers of said at least semiochemical with a substantially constant emission flow and different from the effective flow 1 of stage b), combined with a male insect capture device, where m is the number of diffusers, being m greater than or equal to 1,
- step e) obtaining the final effective flow, by repeating step c), x times until the diffusers with an emission flow equal to the effective flow x, used to prepare the artificial semiochemical matrix x, comprise a greater number of male insects captured, f) obtaining the effective number of diffusers per unit area, by preparing at least one artificial semiochemical matrix in which the emission flow is constant and equal to the final effective flow of stage e) and the number of diffusers it is variable and different from the one used in the previous stages, and that allows the effective control of at least one plague of coconut insects g) obtaining the effective flow through the product of the final effective flow and the effective number of diffusers per unit area.

- Example 1 Obtaining, selecting and using an artificial semiochemical matrix to combat the coccoidea pest A. aurantii, in citrus crops.
- an artificial semiochemical matrix 1 was generated, by placing 500 diffusers / ha, of initial emission flow-1, substantially constant of 300 pg / diffuser / day (optimum flow according to the state of the art) of acetate (3S) , 6flS) -3-methyl-6-isopropenyl-9-decen-1-yl.
- the traps were placed on the trees at a height of 1, 5 m.
- the traps used were sticky sheets of 9.5 x 15 cm and white.
- the substantially constant emission flow diffusers were fixed in the center of the sticky sheet.
- the sheets were replaced, intrablock rotation of the traps and reading of the captured males. Once the rotation of the traps was completed, it was observed that the catches corresponding to the emission fluxes of 15 pg / day were slightly higher (figure 3). That is, the final effective flow to combat this pest by using an artificial semiochemical matrix is 15 pg / diffuser / day.
- the effectiveness of the treatments was evaluated according to the percentage of damaged fruits by means of a sampling before the harvesting of the fruits. To determine this percentage, the counting of the number of female A. aurantii scutes by fruit was made by the following protocol: 20 trees were randomly selected per hectare and, from each tree, 10 fruits were taken: 8 from the outside (of all the orientations and random) and two of the interior (random). A fruit that presented more than 10 escudos was considered damaged. In the case of treatment based on chemical control, an area equivalent to the rest of the treatments was evaluated for prospecting. These data demonstrated the sexual pheromone savings for the California red louse, A. aurantii.
- the flow corresponding to the optimum flow according to the state of the art would correspond to 150 mg per hectare and day (300 pg / day (Vacas et al International Journal of Pest Management 2017, 63, 10-17) in 500 emission points per hectare) , while with the procedure described in the present invention, the value of the effective flow rate determined within the intertwined semiochemical matrix after successive iterations reached values of 2.5 mg per hectare and day (5 pg / day in 500 emission points) per hectare), which implies a decrease in the pheromone flow rate of 98%, obtaining a level of crop damage comparable to that obtained with the application of conventional chemical treatment (paraffinic oil). Comparatively, the control of A.
- aurantii using the technique of sexual confusion uses around 35 g / ha / year of acetate (SS óflSj-S-methyl-e-isopropenyl-O-decen-l-yl, while applying the parameters proposed in this patent application would be advisable, but not limiting, to use 0.7 g / ha / year to combat the plague of the same semiochemical.
- Example 2 Obtaining, selecting and using an artificial semiochemical matrix to combat the coccoidea pest Planococcus ficus, in table grape crops.
- an artificial-1 semiochemical matrix was generated by placing 1,000 diffusers / ha, with a substantially constant emission flow of 300 pg / day of S-lavandulil senecioate (initial flow-1).
- the choice of this initial emission flow is based on the average emission of the commercial diffusers for the control of this pest.
- the traps were placed on the vines at a height of 2 m.
- the traps used were sticky sheets of 9.5 x 15 cm and white.
- the substantially constant emission flow diffusers were fixed in the center of the sticky sheet.
- the sheets were replaced, intra-block rotation of the traps and reading of the captured males. Once the first rotation of the traps was completed, it was observed that those whose emission corresponded to the flows of 5 pg / day and 10 pg / day presented the highest number of captured males (figure 5).
- the final effective flow to combat this pest by the use of an artificial semiochemical matrix is between 5 pg / diffuser / day and 10 pg / diffuser / day.
- the effectiveness of the treatments was evaluated according to the percentage of clusters with the presence of Planococcus ficus, molasses or bold, by means of a sampling before the grape harvest. To determine this percentage, 20 random vines were taken per hectare and in each of them 20 clusters were checked, from which the 10 clusters closest to the center of the vine and the 10 furthest clusters were chosen, covering the entire length of the vine. Both clusters were taken in contact with primary branches, as well as isolated without touching any other branch. In total, 800 bunches per hectare were evaluated. The evaluation of the clusters was estimated according to the values shown in table 4:
- the examples demonstrate that with the method of the present invention, in coccoid species, once the effective flow within the intertwined semiochemical matrix has been reached, it is significantly lower than that determined in the breast. of the natural semiochemical matrix by the methods described in the state of the art (optimal flow), but even more surprising is the finding of different combinations in the conformation of the artificial semiochemical matrix that allow optimal control of the pest.
- This reduction of the semiochemical flow observed between the optimal flow and the effective flow, together with the reduction of the effective number of devices constitute a unique technical-economic combination (effective flow) that entails a very important reduction in the costs of the treatment , which allows this technique to be economically competitive against other methods of chemical and biological control.
