but of which the geometry was essentially E, were certainly known. Let us mention, for example, New Zealand Patent 170797 as well as J.Chem.Soc. Perkin I, page 2470, 1974 and Pest. Sci 1_, page 499, 1976. However the side chain geometry of these compounds was predominantly E. In fact, the synthesis processes used to prepare these derivatives lead almost exclusively only to geometry E (see Agr. Biol. Chem 34, <br><br>
page 1119 1970). For these compounds, of which the geometry of the side chain was E, it has not been possible to make evident any remarkable property. <br><br>
It has just been discovered that certain products, <br><br>
of which the side chain of structure Z and of which the cyclopropane moiety is of IR, cis structure, display exceptional insecticidal properties. <br><br>

A further subject of the invention is the compound (RS)<*;-cyano- (3-benzoylphenyl) methyl (1R,cis,£2)2,2-dimethyl-3- (3-m<ihoxy-3-oxo-1 -propenyl) -cyclopropane-1-carboxylate, which is closely related in structure to the compounds of formula (I1) and which falls within the general formula (I') described and claimed in our co-pending Application No. 196809. This compound is denoted herein Compound Y. <br><br>
The compounds of formula (I') and Compound Y show interesting properties which enable them to be used in the control of pests : this can be, for example, the control of pests of plants, domestic pests and pests of warm-blooded animals. Thus the products of the invention can be used to control insects, nematodes and acaridae which are pests of plants and of animals. <br><br>
The subject of the invention is therefore the use of the compounds of formula (I'), as defined before and of Compound Y, in the control of pests of plants, domestic pests and pests of warm-blooded animals. <br><br>
The product of formula (I') and Compound Y can therefore be used especially to control insects in the agricultural sphere, ;to control, for example, aphicfe , the larvae of lepidoptera and coleoptera. They are used at doses between 10 g and 300 g of active substances per hectare. <br><br>
The products of formula (I1) and Compound Y can-also be used to control insects in the domestic sphere, to control especially flies, mosquitoes and cockroaches. <br><br>
Certain of the products of formula (I') show, in particular, excellent knock-down capacity. <br><br>
The product of Example 1 is particularly remarkable. <br><br>
The products of formula (I) are more photostable and <br><br>

The compositions according to the invention are prepared according to the usual processes of the agro-chemical industry, the veterinary industry or the industry of products intended for animal feeding. <br><br>
In these compositions intended for agricultural and domestic use, the active substance or substances can have added to it/them possibly one or more other pesticidal agents. These compositions can be presented in the form of powders, granules, suspensions, emulsions, solutions, solutions for aerosols, combustible strips, baits or other preparations normally employed for the use of this kind of compound. <br><br>
In addition to the active principle, these compositions contain, in general, a vehicle and/or a non-ionic surface-active agent ensuring, in addition, uniform dispersion of the substances constituting the mixture. The vehicle used <br><br>
. . .. _ <br><br>
- 16 - <br><br>
can be a liquid such as water, alcohol, the hydrocarbons or other organic solvents, a mineral,animal or vegetable oil, a powder such as talc, the clays, the silicates or kieselguhr or a combustible solid. <br><br>
5 The insecticidal compositions according to the invention contain preferably from 0.005% to 10%' by weight of active substance. <br><br>
According to an advantageous modus operandi, for domestic use, the compositions according to the invention 10 are used in the form of smoke-producing compositions. <br><br>
The compositions according to the invention can then be advantageously constituted, for the non-active part, by a combustible insecticidal coil or else by an incombustible fibrous stibstrate. In the latter case the fumigant obtained 15 after incorporating the active substance is placed on a heating apparatus such as an electric mosquito destroyer. <br><br>
In the case in which an insecticidal coil is used, the inert support can be, for example, composed of pyrethrum marc, Tabu powder (or Machilus Thumbergii leaf powder), 20 pyrethrum-stem powder, cedar-needle powder, wood dust (such as pinewood sawdust), starch and coconut shell powder. <br><br>
The dose of active substance can be, for example, <br><br>
from 0.05 to 1% by weight. <br><br>
25 In the case in which an incombustible fibrous support is used, the dose of active substance can then be, for example, from 0.03 to 95% "by weight. <br><br>

The compositions according to the invention^for domestic use,can also be obtained by preparing an atomisable oil based upon active principle, this oil soaking the wick of a lamp and being then subjected to 5 combustion. <br><br>
The concentration of the active principle incorporated in the oil is preferably from 0.03 to 95% "by weight. <br><br>
The insecticidal compositions according to the invention, like the acaricidal and nematocidal compositions, 10 can have added to them possibly one or more other pesticidal agents. The acaricidal and nematocidal compositions can be presented especially in the form of powder, granules, suspensions, emulsions and solutions. <br><br>
For acaricidal use preferably wettable powders for 15 foliar spraying are used containing from 1 to ,80% or liquids for foliar spraying containing from 1 to $00 g/1 of active principle. Powders for foliar spraying can also be used containing from 0.05 to 3% of active substance. <br><br>
For nematocidal use preferably liquids for soil 20 treatment are used containing from 300 to 500 g/1 of active principle. <br><br>
The acaricidal and nematocidal compounds according to the invention are used, preferably, at doses included between 1 and 100 g of active substance per hectare. 25 In order to increase the biological activity of the products of the invention, they may be added to standard synergists used in a similar case such as l-(2,5»8-trioxa- <br><br>
