Furthermore, the present invention relates to processes for the preparation of compounds of formula I, compositions containing them and their use for the control of insect and acarid pests and for the protection of plants from those pests as well as their use for treating, controlling, preventing and protecting warmblooded . animals and humans against infestation and infection by arachnids and arthropod endo- and ectoparasites.
Pyrazoles such as those described in WO 98/45274 or US 5,232,940 are known to demonstrate insecticidal and parasiticidal activity.
WO 98/24767 discloses parasiticidally active pyrazoles carrying a cyclopropyl group in the 4-position.
In EP-A 200 872, pesticidal pyrazoles are described that carry "a N02-group in the 4-position and may carry a C3-C-cycloalkyl group in the 3-position.
However, the pesticidal activity of the compounds known from the above literature in many cases is unsatisfactory.
It is therefore an object of the present invention to provide further compounds having improved insecticidal and acaricidal ac- tivity.
It is also an object of the present invention to provide compounds having improved parasiticidal activity.
We have found that these objects are achieved by pyrazole derivatives of formula I. Furthermore, we have found processes for preparing the compounds of formula I and the use of the compounds I and compositions comprising them for use for the control of insects and arachnids and for the protection of growing and harve- sted crops and wooden structures from damage caused by insect and acarid attack and infestation, as well as the use of compounds of formula I for treating, controlling, preventing and protecting warm-blooded animals and humans against infestation and infection by arachnids and arthropod endo- and ectoparasites.
The pyrazole moiety of the compounds described in WO 98/45274 or US 5,232,940 is not substituted by a cycloalkyl group.
Contrary to the parasiticidal compounds disclosed in WO 98/24767, the inventive compounds of formula I carry a cyclopropyl group in the 3-position of the pyrazole moiety.
The compounds of formula I differ from the compounds known from EP-A 200 872 in that the pyrazole moiety is substituted by cyclo- propyl.
Depending on the substitution pattern, the compounds of formula I can contain one or more chiral centers, in which case they are present as enantiomer or diastereomer mixtures. Subject matter of the invention are the pure enantiomers or diastereomers as well as their mixtures .

The reaction mixtures are worked up in a customary manner, for example by mixing with water, phase separation and, if appropriate, chromatographic purification of the crude products. In some cases, the intermediates and end products are obtained in the form of colorless or pale brown viscous oils, which are purified or freed from volatile components under reduced pressure and at moderately elevated temperature. If the intermediates and end products are obtained as solids, they can also be purified by recrystallization or digestion.
The preparation of the pyrazoles of formula I may lead to isomeric mixtures, if desired, however, these can be resolved by the methods customary for this purpose, such as crystallization or chromatography, also on an optically active adsorbate, to give the pure isomers . Pure optically active isomers can be synthesized advantageously from the corresponding optically active, starting material.
