In order to increase the pseudoacaricidal effect, the proposed pest-containing insecticide agent contains as an active substance (ADV) from the dinene of the general formula I Y - .. To o-tHr H2-iH-o: where Rjt Cj-Cj is alkenyl nyl or Cj-C alkynyl; hydrogen, or methyl; Y is a sulfur atom or a methylene group, E is an amount of 0.1-95 wt.%, The rest is a filler and / or a diluent. Alkenyl, chloralkenyl and quinil as can be normal or isostroin. Alkenyl and chloroalkenyl include allyl or buten-r2-yl, as well as 1-methylallyl, 2-methylallyl, 3-methylallyl or 1,2-dimethylallyl, and their chlorine substituted derivatives, for example 1-chloroallyl, 2-chloroallyl ,. 2-chloromethylamine and 1-me yl-2-hlog allyl. The suitable alkynyl radicals can be propargyl butyn-3-yl-2, 2-methyl-butyl-3-yl-2. These compounds of general formula I are suitable for pest control, primarily for controlling phytopathogenic insects, in particular with larvae of larvae and pupae of insects and larvae (clears), in particular, for pests in fruit-growing, for example, citrus, atazhe to combat domestic parasites. The most important are the compounds of the formula I, where allyl, buten-2g-il, 3-chlorallyl or propargyl /, As examples of A DB, substances of formula I can be distinguished, in which Y have the following CH values: UN-CH ,, t -CH CH-CH-CH - CH CH C-CP4 (CH3), (CH) CHSC-CH 2CHSC-CH (CbJ -, t-CH "CH-CH CH -CH CH-CH - CHgCHaC-CH sn -CH (CH) - n-CE CH CH SN2CH -CH H-CHg- n among the insects on which affect vpieukazannymi ADV, otnoAct ididae, B oiUidae, (3ie, y2PolaPpidoie, Teiligottnd ae, Ciwiiudoie, P rrhoconidQie, T eduvndlo e doie, stotrtoxydoie, Muscidae Ca8Eiphoridoie, Trypei4dae und.

.one. Contact action on the pupae. A certain amount of O, 1O% solution of ADV in acetone, corresponding to 1O mg of active substance per 1 m, is pipetted into an aluminum pan and evenly distributed. After evaporation of acetone 1O, the TeriebHo moEttot pupae that have passed the molting stage are placed on the treated surface. Then the cup is closed with a mesh lid. After untreated control individuals have left the shell of the pupae and become adults, an examination of the experimental specimens developed from the pupae treated with the proposed remedy is carried out in order to determine the number of normal adults. The assessment is carried out according to the tiballic theme: 5 points - 10% of lethal special forms (special pupae and adultoid 4 points - lethal and non-lethal special forms (adultoidy); 3 points lethal and non-lethal special forms and normal age; 2 points - non-lethal special forms and normal adults. 1 point - 100% normal adults K. Contact action on larvae of lerCus lascialus. A certain amount of a 0.1% solution of activating substance in acetone, corresponding to 10 mg of active substance per 1 m, is pipetted into an aluminum cup. and ra After evaporation of the acetone, 10 larvae of the fifth stage DesiefCUS lor, CtOiius are placed on the treated surface of the cup containing feed and wet cotton. Then the cup is closed with a mesh of kg: hoi. the individuals will go through the adult molting stage) will examine the experiment) and. (x individuals that develop from the larvae treated as described to determine the number of normal adults. Open skin: 5 points - 1OO% are lethal special forms (linging dead and oso (5th larvae); 4 points are lethal and non-lethal special forms (adultoids); 3 points are lethal, non-lethal special forms and normal adults; 2 points are non-lethal special forms and normal adults; 1 point - 100% normal adults. Action Spodeptera iH-iOCQ iS (eggs). Spodeptera fttora./S eggs are placed in a solution of 0, O5 wt.% LDV in a mixture of water and acetone 1: 1. Then the eggs removed from the LDV solution and placed in storage in plastic cups at 25 ° C and 60% relative humidity. the number of larvae that hatched from the treated eggs. Evaluation: 5 points - no hatched larvae (efficiency 100%); 4 - points - no less than the processed eggs hatched (the efficiency 90 %); 1 point - larvae hatched from more than 1% of treated eggs (efficiency%) IV: Effect on Musca domesUcQ. Weighed 50 g of freshly burned () nutrient substrate for the larvae and put it in cups. A certain amount of a solution of 1% by weight of the corresponding LDV in acetone is applied to the substrate in the glasses and a concentration of the active substance in the substrate is obtained of 0.1%; 0, O5% and 0.01%. After stirring, the substrate is allowed to evaporate to acetone for at least 20 hours. Then 25 one-day larvae are placed in cups containing the nutrient substrate treated in this way. After the larvae pupate, the formed pupae are separated from the substrate by leaching with water and placed in storage in vessels closed with mesh covers. The pupae that were washed from each solution were counted (the toxic effect of the active substance on the larval development). Then after 10 days

The number of flies hatched is determined by the flies, and thus the possible effect on metamorphosis is established. Score: 1 point - flies at 0.1% LDV;

2 b.allah-no flies at 0.1% LDV; 3 points - no flies at 0, O6% LDV; 5 points no flies with 0.01% LDV.

V. Effect on Aedes ae ypijf (larvae). On the surface of 150 ml of water in the vessel with a pipette, such an amount of a 0.1% solution of the active substance is added, which ensures the concentration of the last 1 O, 5 and 1 ppm. After evaporation of the acetone, 30–40 two-day old Lyodes aedypiy larvae are placed into each vessel filled with L-and-5s. Apply 2 vessels for each LS concentration. Then, ground feed is introduced into the vessels and covered with copper mesh covers.

After 1.2 and 5 days, check for possible mortality. G (x: less than this should be followed by a violation of pupation, meta or (0) and adult; good molting. Evaluation is carried out according to the following scale:

1 point - flies with lOppm (without result);

2 points - no flies at YuRGP; 3 points no flies at D) PpfT); 5 points - notes of flies at 1 00 (71 (1OO% effect E-)). The results obtained are summarized in Table 2. 136 claims 1. An insecticide-acaricidal agent containing an active substance, a carrier and / or a diluent, is distinguished; so that, in order to increase the insectoacariid effect, a compound of the general formula I 0-CH2-CH2-CH-OT, where T is alkenyl, C-C-chloroalkenyl or Ca-Cc alkynyl, is used as an active substance; ; H - sulfur atom or methylene group in the amount of 0.1-9 5 wt.%, And the rest of the carrier and / or dilute Spruce.
