     DETAILED DESCRIPTION OF THE INVENTION 
     A variety of insects and acarina cause great economic loss by damaging or destroying agricultural crops and other valuable plants; by aiding in the spread and development of bacteria, fungi and viruses that produce diseases of plants; and by destroying or lowering the value of stored foods, other products and possessions. Insects and acarina present some of the farmers&#39; greatest problems the world over. The need for alternative and effective insect and acarid control is a global concern. 
     It has now been found that the substituted acid amide, N-arylhydrazone compounds of formula I are especially efficacious insecticidal and acaricidal agents, particularly against Coleoptera, Lepidoptera and Acarina. 
     The formula I amidrazone compounds of the present invention have the structural formula ##STR6## wherein A, B, W, Y, n, R, R 1 , R 2  and R 3  are described hereinabove. The term halogen as used in the specification and claims designates chlorine, fluorine, bromine or iodine. The term acid addition salts designates those salts formed by acids commonly known in the art such as hydrogen chloride, hydrogen bromide, hydrogen bisulfate, hemi-hydrogen sulfate and the like. In the above definition when n is O then Y is hydrogen. 
     Preferred compounds of the invention are those wherein R, R 2  and R 3  are each independently hydrogen or C 1  -C 6  alkyl, A is C--R 4 , B is C--R 5 , W is C--R 6 , Y is halogen and n is 1. Particularly preferred compounds are those wherein R 1  is hydrogen, R 4  is halogen, R 5  is hydrogen and/or R 6  is C 1  -C 6  alkyl substituted with one or more halogens, preferably trifluoromethyl. 
     Other preferred compounds of the invention are compounds having the structure ##STR7## wherein R is C 1  -C 10  alkyl; 
     R 1  is hydrogen or C 1  -C 4  alkyl; 
     R 2  is C 1  -C 10  alkyl; 
     R 3  is hydrogen or C 1  -C 10  alkyl; and 
     R 4 , R 6  and Y are each independently hydrogen, halogen, CN, NO 2 , C 1  -C 6  alkyl, C 1  -C 6  haloalkyl, C 1  -C 6  alkoxy, or C 1  -C 6  haloalkoxy. 
     The N-arylamidrazones of formula I may be prepared by reacting an acid chloride, hydrazone (hydrazinoyl chloride) of formula II with an amine compound, HNR 2  R 3 , as shown in flow diagram I. 
     Flow Diagram I ##STR8## 
     Compounds of formula II may be prepared by reacting a suitable arylhydrazine of formula III with the appropriate acid chloride, RCOCl, to obtain an N-arylhydrazide of formula IV and reacting the formula IV hydrazide with a chlorinating agent such as thionyl chloride to give the desired formula II N-arylhydrozinoyl chloride product. The reaction is illustrated in flow diagram II. 
     Flow Diagram II ##STR9## 
     The substituted N-arylamidrazone compounds of the present invention are effective for controlling insect and acarid pests. Said compounds are also effective for protecting growing or harvested crops from attack and infestation by such pests. 
     In practice, generally about 10 ppm to 10,000 ppm, preferably about 100 to 5,000 ppm of the formula I compound dispersed in a liquid carrier, when applied to the plants or the soil or water in which they are growing, is effective to protect the plants from insect and acarina attack and infestation. Soil application of the formula I compounds is particularly effective for the control of the post-embryonic development stages of Coleoptera and Diptera. Applications, such as spray applications, of compositions of the invention are generally effective at rates which provide about 0.125 kg/ha to about 250 kg/ha, preferably about 10 kg/ha to 100 kg/ha. Of course, it is contemplated that higher or lower rates of application of the N-arylamidrazone compounds may be used dependent upon the prevailing environmental circumstances such as population density, degree of infestation, stage of plant growth, soil conditions, weather conditions and the like. 
     Advantageously, the compounds of the invention may be used in conjunction with, or in combination with other biological and chemical control agents including other insecticides, nematicides, acaricides, molluscicides, fungicides and bactericides such as nuclear polyhedrosis viruses, pyrroles, arylpyrroles, halobenzoylureas, pyrethroids, carbamates, phosphates, and the like. 
     Typical formulations suitable for the formula I compounds of the invention are granular compositions, flowable compositions, wettable powders, dusts, micro-emulsions, emulsifiable concentrates and the like. All compositions which lend themselves to soil, water and foliage application and provide effective plant protection are suitable. Compositions of the invention include the formula I N-arylamidrazone amide compound admixed with an inert solid or liquid carrier. 
     Where compositions of the invention are to be employed in combination treatments with other biological or chemical agents, the composition may be applied as an admixture of the components or may be applied sequentially. 
     For a more clear understanding of the invention, specific examples thereof are set forth below. These examples are merely illustrative, and are not to be understood as limiting the scope and underlying principles of the invention in any way. 
    
    
     EXAMPLE 1 
     Preparation of 2,2-Dimethylpropionic acid, 2-(2,6-dichloro-α,α,α-trifluoro-p-tolyl)hydrazide ##STR10## 
     A solution of 2,6-dichloro-4-(trifluoromethyl)phenylhydrazine (50.0 g, 0.20 mol) in methylene chloride is treated dropwise with trimethylacetyl chloride (30.6 g, 0.254 mol), stirred for 30 minutes, treated with 10% aqueous NaOH and stirred for 3 hours. The phases are separated; the organic phase is washed with water, dried over MgSO 4  and concentrated in vacuo to give an off-white solid residue. The solid is recrystallized from 1,2-dichloroethane to give the title product as a white solid, 55 g (82% yield), mp 140°-141°, identified by  1  HNMR,  13  CNMR and IR spectral analyses.

     EXAMPLE 170 
     Insecticidal and Acaricidal Evaluation of N-aryl-amidrazone compounds 
     Test solutions are prepared by dissolving the test compound in a 35% acetone in water mixture to give a concentration of 10,000 ppm. Subsequent dilutions are made with water as needed. 
     Spodoptera eridania, 3rd instar larvae, southern armyworm 
     A Sieva limabean leaf expanded to 7-8 cm in length is dipped in the test solution with agitation for 3 seconds and allowed to dry in a hood. The leaf is then placed in a 100×10 mm petri dish containing a damp filterpaper on the bottom and ten 3rd instar caterpillars. At 3 and 5 days, observations are made of mortality, reduced feeding, or any interference with normal molting. 
     Tetranychus urticae (OP-resistant strain), 2-spotted spider mite 
     Sieva limabean plants with primary leaves expanded to 7-8 cm are selected and cut back to one plant per pot. A small piece is cut from an infested leaf taken from the main colony and placed on each leaf of the test plants. This is done about 2 hours before treatment to allow the mites to move over to the test plant to lay eggs. The size of the cut, infested leaf is varied to obtain about 100 mites per leaf. At the time of test treatment, the piece of leaf used to transfer the mites is removed and discarded. The newly mite-infested plants are dipped in the test solution for 3 seconds with agitation and set in the hood to dry. After 2 days, one leaf is removed and mortality counts are made. After 5 days, another leaf is removed and observations are made of mortality of the eggs and/or newly emerged nymphs. 
     Diabrotic undecimpunctata howardi, 3rd instar southern corn rootworm 
     One cc of fine talc is placed in a 30 ml wide-mouth screw-top glass jar. One mL of the appropriate acetone test solution is pipetted onto the talc so as to provide 1.25 mg of active ingredient per jar. The jars are set under a gentle air flow until the acetone is evaporated. The dried talc is loosened, 1 cc of millet seed is added to serve as food for the insects and 25 mL of moist soil is added to each jar. The jar is capped and the contents thoroughly mixed on a Vortex Mixer. Following this, ten 3rd instar root-worms are added to each jar and the jars are loosely capped to allow air exchange for the larvae. The treatments are held for 6 days when mortality counts are made. Missing larvae are presumed dead, since they decompose rapidly and can not be found. The concentrations used in this test correspond approximately to 50 kg/ha.
