The insecticidal and acaricidal compositions of the invention can be effectively applied in the agro-horticultural field.

ANTECEDENTS OF THE TECHNIQUE Compound A, which is an active ingredient of the insecticidal and miticidal composition of the invention, is an insecticidal and acaricidal agent against agro-horticultural pests and is known to be effective against insects such as pests such as pests of H e m p t e r a t a l as s a l t a r i l a (Doltocephalidae), lepromatoptera pests such as the diamond back moth (Plutella xylostella), common nocturnal caterpillar (Spodoptera litura), and apple leafminer (Phyllonorycter ringoniella), and plague of Thysanoptera such as Thrips of the palm and Thrips of the yellow tea (Spirtothrips REF: 29793 dorsalis) and agrohorticultural pests such as mites such as the spider mite (Tetranychus urticae koch), the spider mite or Kanzawa (Tetranychus kanzawai kishida) and Aculops pel e-kassi.

Of the compounds mentioned above, they are known to be effective against agrohorticultural pests such as insects such as Hemiptera, Lepidoptera and Coleoptera insects or mites. Hitherto, acaricidal insecticidal agents have been developed in order to control various pests such as agro-horticultural pests or hygienic pests and have been used in practice alone or in mixtures. Nevertheless, pests which have acquired resistance against various agents have been appearing as a result of the repeated use of these agents. In particular, spider mites (Tetranychidae) are prone to easily develop resistance against pesticide agents due to their ability to deposit large quantities of eggs and produce large quantities of generations which, in themselves, require only a few days for their development , have a high rate of mutation and frequent endogamous growth, due to minimal migration. For these reasons, the two-spot spider mite . { Tetranychus urticae koch), Kanzawa spider mite (Tetranychus kanzawai kishida), Aculops pelekassi, and the like have acquired resistance, to some extent, against almost all existing plagiarism agents.

Therefore, in order to avoid and control the damage caused by spider mites, the development of an insecticidal and acaricidal agent which shows an elevated effect against spider mites which have acquired resistance against conventional acaricidal agents is highly desirable. However, to invent an insecticidal and acaricidal composition which does not show cross-resistance with existing insecticidal and acaricidal agents, which do not present problems of toxicity and which has little negative impact on the environment, is extremely difficult. In addition, a period of almost 10 years is required for the development of an invention. Therefore, in order to apply an effective agent for a long time, the rotational application of agents with different mechanisms of action for a good practice of pest control has been adopted. However, this approach does not necessarily provide satisfactory results. After a resistance problem has arisen, a countermeasure for resistance has been studied using a combination of insecticidal and acaricidal agents. However, a high synergistic action has not always been found. On the other hand, compound A, which is an active ingredient of the insecticidal and acaricidal composition of the invention, has reached the market very recently and shows a high acaricidal effect now even when used alone. However, from the background of resistance problems of almost all acaricidal agents in the past, it is likely that a similar problem may arise with compound A, too. The object of this invention is to provide an acaricide composition which demonstrates a high level of control against spider mites which has an acquired resistance against compound A.

DESCRIPTION OF THE INVENTION In order to provide a countermeasure to the problem of spider resistance against compound A before such a problem occurs, the synergistic action was studied with existing insecticidal, acaricidal and fungicidal agents using resistant species which have been artificially established in the laboratory when selecting spider mites which have been treated with compound A. Therefore, it has now been found that a composition which contains compound A in combination with pyrethroid insecticidal ingredients demonstrates a synergistic joint effect which can not be anticipated from each individual ingredient, and is very effective as an insecticidal and acaricidal composition, resulting in the obtention of this invention. Therefore, the main point of the present invention resides in insecticidal and acaricidal compositions characterized in that 4-bromo-2- (4-chlorophenyl) -1- (ethoxymethyl) -5- (trifluoromethyl) pyrrole-3-carbonitrile (Compound A ). The representative spider mites controlled by the present invention are: two-spot spider mite (Tetranychus urticae koch), Tetranychus cinnabarinus (Boisduval), Kanzawa spider mite (Tetranychus Kanzawaikishida), hawthorn spider mite (Tetranychus viennensiszacher) and the like. Advantageously, the insecticidal and acaricidal composition of the invention show not only a synergistic acaricidal appearance against the aforementioned spider mites, but also demonstrate simultaneous control of problematic pests of fruit trees, for example citrus fruits, apples and pears such as odorata moths. the leaves (Tortri cidae), the leafminer moths Carposinidae (Lyonetii dae), plant bugs (Pentatomi dae), aphids (Aphi didae), jumping (Del tociphalidae) and thrips (Thripidae); on tea plants such as leafhoppers, aphids and Thrips; about vegetables such as diamond back moths (Pl utella xylostella), Mamestra brassicae, leaf weevils (Chrysomelidae), aphids, white flies (Al eyrodidae), thrips and the like. Compound A, which is an active ingredient of the insecticidal and acaricidal composition of the invention, is a known compound described in Japanese Patent Laid-Open Publication (Kokai) No. 104042/89, and its method of use as an agent insecticide and acaricide agrohorticultural is also shown in the publication.

EXAMPLE OF FORMULATION 5 (AEROSOL) The ingredients mentioned above are mixed, dissolved and filled into an aerosol container, and after joining a valve part, 60 parts of propellant (LPG / DME mixed gas) are pressed through the valve part to obtain a spray. The effectiveness and usefulness of the insecticidal and acaricidal composition of the invention is demonstrated by the following test example.

EXAMPLE OF TEST 1 The test for the acaricidal effect against female images (adults) of Kansawa spider mites (Tetranychus kanzawai ki shida) which are resistant to compound A. Round leaf discs (2 cm diameter) are cut from a first leaf of kidney bean when using a sheet punch and four sheet sheets are placed on wet sanitary cotton in a 8 cm diameter PVC container. Each leaf disc is inoculated with four female Kanzawa spider (Tetranychus kanzawai ki shida) which has acquired a strong resistance to compound A. After inoculation, the insecticidal and acaricidal composition of the invention, compound A and pyrethroid insecticidal agent or agents are dispersed in water containing 200 ppm of a diluent (Sorpol 3005X, manufactured by Toho Chemical Industry Ltd.) and are diluted so as to obtain the predetermined concentration of active ingredient. Each PVC container is sprayed with 3.5 ml of the test solution by using a rotating spray tower (manufactured by Mizuho Scientific Co., Ltd.) and stored in a constant temperature chamber maintained at 25 + ° C (32 individuals are tested by concentration, 4-5 concentrations are evaluated per formulation and two operations are repeated). Two days after the treatment, investigated the number of live and dead female Kansawa spider mite (Tetranychus kanzawai kishida) on the leaf disk and mortality (%) was calculated according to the formula shown below. From these mortality data, the LC50 values are obtained by the conventional probit method.

Mortality (%) = Number of dead mites X 100 Number of live mites + number of dead mites In addition, the coefficient of co-toxicity was calculated by applying the formula of Sun and Johnson (J. Econ. Ent., Vol. 53, p.887, 1960) which is generally used to determine the degree of synergistic activity. The LC50 value of each individual active ingredient, which constitutes the insecticidal and miticidal composition of the invention, is shown in Table I. The LC50 values and co-toxicity coefficients calculated by the Sun and Johnson formula mentioned below of the composition of the invention are shown in Table II.

Co-toxicity coefficient = actual toxicity index of the mixture X 100 theoretical toxicity index of the mixture For the values mentioned above greater than 100, a larger value indicates a stronger synergistic action. For a value equal to 100, an additive action is indicated. For values less than 100, the smaller value indicates a larger antagonistic action. A more detailed description of the calculation of the co-toxicity coefficient of the Sun and Johnson method mentioned above is as follows. Each LC5n value of test compound A and test compound B is determined and the LC50 value of the mixture thereof is determined. actual toxicity index of the mixture M = LC50 of the test compound A X 100 LC5n of the mixture M theoretical toxicity index of the mixture M = (toxicity index of compound A of test X proportion of compound A of test in mixture M (%) + toxicity index of compound B of test X proportion of compound B of test in the mixture M (%)) X 100. With the proviso that the toxicity indices of test compound A and test compound B are the following: toxicity index of test compound A = 100 toxicity index of test compound B = LC50 of test compound A X 100 LC50 of test compound B TABLE I Effect of compound A and pyrethroid insecticidal agents against female Kanzawa spider that have acquired resistance against compound A.

The acaricidal effect of each compound is tested by using females from a colony resistant to compound A which is obtained by a prolonged artificial selection procedure with compound A in a laboratory in a colony of Kanzawa spiders which have been collected in the countryside. The effect of compound A is 1500 ppm as the LC5C value. Since the effect of compound A against the susceptible strains of spider mites, which is not mentioned in the Table, is about 5 ppm as LC50 value, this strain developed with approximately 300 times resistance against compound A. Since this Kanzawa spider comes from a colony which has acquired resistance against the pyrethroid insecticide agents already at the time of harvesting in the field, all tested pyrethroid insecticidal agents show only low effects.

Table II Effect and synergistic action of the insecticidal and acaricidal composition of the invention against Kanzawa spider females which have acquired resistance against compound A.

Since the coefficients of co-toxicity of the insecticidal and miticidal compositions of the invention all have values that exceed by much to 100, it is considered that in the test example a strong synergistic action of Compound A and Etofenprox, Cihalotrine, has been demonstrated, Cyfluthrin, Cypermethrin, Piretrum, Bifenthrin, Fenpropathrin, Fluvalinate or Permethrin.

INDUSTRIAL APPLICABILITY The present invention provides effective insecticidal and acaricidal agents against pests and mites, the which are resistant against insecticidal and acaricidal agents currently on the market. It is noted that in relation to this date, the best method known to the applicant to carry out the aforementioned invention, is the conventional one for the manufacture of the objects or products to which it refers.
