One group of preferred vertebrates of the present invention comprises warm-blooded animals, including farm animals such as cattle, horses, pigs, sheep and goats, poultry such as chickens, turkeys, guinea fowls and geese, fur animals such as minks, foxes, chinchillas, rabbits, etc., and companion animals such as ferrets, guinea pigs, rats, hamsters, cats and dogs, and humans. Another group of preferred vertebrates of the present invention comprises fish, including salmon.

[0890] In the context of the present invention, ectoparasites are understood to be, in particular, insects, acarina (mites and ticks) and crustaceans (sea lice). These include insects of the following orders: Lepidoptera, Coleoptera, Homoptera, Hemiptera, Heteroptera, Diptera, Dictyoptera, Thysanoptera, Orthoptera, Anoplura, Siphonaptera, Mallophaga, Thysanura, Isoptera, Psocoptera and Hymenoptera. However, ectoparasites that may be mentioned in particular are those that plague humans or animals and carry pathogens, for example flies, such as the housefly (Musca domestica), the Australian bushfly (Muscavetustissima), the fall housefly (Musca autumnalis), the summer toilet fly (Fannia canicularis), the flesh-eating flesh fly (Sarcophaga carnaria), the copper green fly (Lucilia cuprina), the silk green fly (Lucilia sericata), the cow hide fly (Hypoderma bovis), the skin fly (Hypoderma lineatum), the green-tailed goldfly (Chrysomyia chloropyga), the human skin fly (Dermatobia hominis), the American blowfly (Cochliomyia hominivorax), the intestinal fly (Gasterophilus intestinalis), the sheep fly (Oestrus ovis), biting flies such as the western horn fly (Haematobia irritans irritans), the oriental horn fly (Haematobia irritans exigua), the stable fly (Stomoxys calcitrans, Tabanids and the subfamily Tabanidae, such as Haematopota spp. (e.g. Haematopota pluvialis) and Tabanus spp. (e.g. Tabanus nigrovittatus), and the subfamily Chrysopsinae, such as Chrysops spp.) (e.g., Chrysops caecutiens); Hippoboscids, such as Melophagus ovinus (sheep tick); tsetse flies, such as Glossinia spp.; other biting insects, such as midges, such as Ceratopogonidae (biting midges), Simuliidae (black mosquitoes), Psychodidae (sand flies); and blood-sucking insects, such as mosquitoes, such as Anopheles spp., Aedes spp., and Culex spp., fleas, such as Ctenocephalides felis and Ctenocephalides canis (cat and dog fleas), Xenopsylla spp. cheopis), human flea (Pulexirritans), chicken horned leaf flea (Ceratophyllus gallinae), skin-piercing tick (Dermatophilus penetrans), blood-sucking lice (Anoplura), such as long jaw lice species (Linognathus spp.), blood lice species (Haematopinus spp.), tube lice species (Solenopotes spp.), human lice (Pediculus humanis); and chewing hair lice (Mallophaga), such as wool lice (Bovicola (Damalinia) ovis), cattle hair lice (Bovicola (Damalinia) bovis), and other feather lice species (Bovicola spp.).

Representative ticks are, for example, Boophilus, Amblyomma, Anocentor, Dermacentor, Haemaphysalis, Hyalomma, Ixodes, Rhipicentor, Margaropus, Rhipicephalus, Argas, Otobius, and Ornithodoros, etc., which preferably infect vertebrates, such as warm-blooded animals, including farm animals such as cattle, horses, pigs, sheep and goats, poultry such as chickens, turkeys, guinea fowls and geese, fur animals such as minks, foxes, chinchillas, rabbits, etc., and companion animals such as ferrets, guinea pigs, rats, hamsters, cats and dogs, as well as humans and fish. .

[0891] The compounds of the invention according to the invention are also active against all or individual developmental stages of animal pests that show normal sensitivity, as well as those that show resistance to widely used parasiticides. This is especially true for resistant insects and members of the order Acarina. The insecticidal, ovicidal and / or acaricidal effect of the active substances of the invention can be manifested directly, i.e. killing the pests immediately or after a period of time, for example when molting occurs or by destroying their eggs, or indirectly, for example by reducing the number of eggs laid and / or the hatching rate, with good efficacy, equivalent to an insecticide rate (mortality) of at least 50 to 60%.

[0892] The compounds of the invention can also be used against hygiene pests, in particular of the families Muscidae, Sarcophagidae, Anophilidae and Culicidae of the order Diptera; the orders Orthoptera, Dictyoptera (for example Blattidae (cockroaches), such as Blatella germanica, Blatta orientalis, Periplaneta americana) and Hymenoptera (for example Formicidae (ants) and Vespidae (wasps)).

[0893] The compounds of formula (I) are also effective against ectoparasites of fish, in particular Copepoda, such as Siphonostomatoida (sea lice), while being well tolerated by fish.

[0894] The compounds of formula (I) may also be used against helminths of the class Cestoda, including the subclasses Eucestoda and Cestodaria.

[0895] The compounds of the invention also have a sustainable effect on parasitic mites and insects of plants. For spider mites of the order Acarina, they are effective against eggs, nymphs and adults of the family Tetranychidae (Tetranychus spp. and Panonychus spp.).

[0896] They are highly active against sucking insects of the order Homoptera, in particular against Aphididae, Delphacidae, Cicadellidae, Psyllidae, Loccidae, Diaspididae and Eriophydidae (e.g. rust mites on citrus fruits); pests of the orders Hemiptera, Heteroptera and Thysanoptera, and plant-feeding insects of the orders Lepidoptera, Coleoptera, Diptera and Orthoptera.

[0897] They are also suitable as soil insecticides to combat soil-borne pests.

[0898] Thus, the compounds of formula (I) are effective against all developmental stages of sucking and feeding insects on crops such as corn, cotton, rice, corn, soybeans, potatoes, vegetables, fruit, tobacco, hops, citrus, avocado and other crops.

[0899] The compounds of formula I are also effective against plant nematodes of the genera Meloidogyne, Heterodera, Pratylenchus, Ditylenchus, Radopholus, Rizoglyphus, and the like.

[0925] Example A

[0926] In vitro evaluation of feeding activity against fleas (Ctenocephalides felis)

[0927] For flea ingestion assays, compound stocks were serially diluted in DMSO to achieve an EC 50 and EC 90 Desired range for the assay. Aliquots of each compound dilution were added to organic bovine blood with a final DMSO concentration of 0.5% and placed in artificial feeding containers. Fipronil was included as a positive control. Ten newly emerged, unfed adult fleas, 0 to 7 days old Ctenocephalides felis from a laboratory colony were sucked into each vial or cage 0. Cages for flea ingestion assays were maintained in a temperature-controlled artificial feeding device to allow continuous access to organic bovine blood containing the desired concentration of compounds. Fresh aliquots of bovine blood spiked with compounds were provided daily during the study. The percentage mortality of fleas was evaluated at various time points between 2 hours and 48 hours after infestation. Fleas that exhibited normal movement and / or jumping ability were considered vigorous, while fleas that exhibited no movement after tapping the vial were assessed as dead.

[0928] In this test, for example, the following compounds from the Preparative Examples showed EC50 < 1 ppm: Example 2.1 or 2.2; 3.1 or 3.2; 3.3 or 3.4; 3.8; 3.19 or 3.20; 3.21 or 3.22; 3.23; 3.27, 3.28, 3.29 or 3.30; 3.34 or 3.35; 3.36 or 3.37; 3.38 or 3.39; 3.40 or 3.41; 3.43 or 3.44; 3.45 or 3.46; 3.49; 3.50 or 3.51; 3.52 or 3.53; 3.54 or 3.55; 3.56 or 3.57; 3.58 or 3.59; 3.60 or 3.61; 3.62 or 3.63; 3.64 or 3.65 50; 3.51; 3.52; 3.53; 3.55; 3.62; 3.65; 3.66; 3.71; 3.73; 3.74; 3.76; 3.77; 3.78 or 3.79; 3.80:3.83; 3.84; 3.85; 3.86; 3.87; 3.90; 3.91; 3.93; 5.1; 8.1 or 8.2; 8.3 or 8.4; 8.5 or 8.6; 9.1 or 9.2; and 9.3 or 9.4; and 10.1 or 10.2.

[0929] In this test, for example, the following compounds from the Preparative Examples showed EC50 < 3 ppm: Examples 1.1 or 1.2; 3.5 or 3.6; 3.15; 3.16 or 3.17; 3.25; 3.26; 3.47; 3.61; 3.72; and 3.75; 3.81; 3.75; 3.92; and 4.3 or 4.4.

[0930] For the above data, when a single isomer is tested, without knowing the absolute configuration of the isomer, the data indicates that the test article is one isomer or the other, e.g. a single isomer from Example 2 is tested and EC 50 of<1ppm, so the above data show that the results are obtained for "2.1 or 2.2".

[0931] Example B

[0932] In vitro evaluation of contact activity against adult ticks (Rhipicephalus sanguineus)

[0933] For the tick assay, vial caps were pre-drilled with a single hole in the center of each cap to allow air exchange. Filter paper (Whatman grade 540 2.1 cm) was placed in the cap of each vial. An aliquot from each compound stock solution was added to the acetone / triton solution to give the highest dose required for the study. Serial dilutions were performed from the highest dose to achieve an EC 50 and EC 90The desired titration range for the assay. The final DMSO concentration in each test vial was 0.5%. A 459 μL aliquot of each compound preparation was transferred to a vial containing Whatman grade 5402.1 cm filter paper. The vial was immediately placed on an unheated roller unit so that the vial wall was evenly coated. After the vial was coated, 41 μL of each compound preparation was added to the filter paper embedded in the cap of each vial. Allow each cap to dry. The vials were loosely capped and allowed to dry in a chemical fume hood for at least 4 hours. 10 adult ticks were added to each vial and maintained at 24 ° C, 80% humidity for a 12-hour light / dark cycle. The percentage mortality of adult ticks was assessed at different time points between 2 hours and 48 hours after infestation. Ticks were stimulated on a heated roller device and evaluated. Ticks that did not show movement or very slow and uncoordinated movement were recorded as dead.
