RU1462530C - Pheromone for attracting male exclamator cutworms - Google Patents

Abstract

The invention relates to agriculture. namely, plant pest control agents. The purpose of the invention is to increase the attractive activity for male exclamatory scoops. As an attractant, cis-5-tetradecenic acetate and cis-9-tetradecene acetate are used, and cis-7-hexadecenyl acetate and cis-5-decenyl acetate are additionally introduced in the following ratio of components, wt%: cis-5-tetradecenyl acetate 37 5 - 85.5; cis-9-tetradecenyl acetate 4.5-375; cis-7-hexadecenyl acetate 1.0 - 25.0; cis-5-decenyl acetate 0.01-0.025. The attractant provides the ability to monitor the exclamation scoop, its distribution and abundance, and reduces the use of insecticides. 1 Z.P.F-LY, 2 tab.

Description

The invention relates to agriculture, and in particular to means for controlling plant pests.

The purpose of the invention is to increase the attractive activity and species specificity for male exclamation scoops.

PRI me R. In a 500 ml round bottom glass flask with a ground stopper, 75 ml of cis-5-tetradecenyl acetate (cis-5TDA), 75 mg of cis-9-tetradecenyl acetate (cis-9TDA) and 50 mg of cis-7-hexadecenylacetate ( cis-7GDA). All substances are weighed on an analytical balance in a micropipette and thoroughly rinsed into a 5 ml hexane flask per pipette. An additional 5 ml of hexane was added to the flask and the whole was thoroughly mixed. 100 medical corks weighing 0.6 g each are quickly loaded into the prepared solution, close the flask of the polished cork and shake until the solution is completely absorbed. The cork that is so-so-so are sealed in foil laminated on both sides with polyethylene and lavsan. The package is opened immediately before the cork is placed in the trap. In this example, each cork contains 0.75 mg of CIS-5TDA, 0.75 mg of cis-9TDA and 0.5 mg of CIS-7HDA (Table 1, sample 1).

For the preparation of a four-component mixture containing 0.75 mg of cis-5TDA, 0.75 mg of CIS-9TDA. 0.5 mg of cis-7HDA and 0.0005 mg of cis-5-deenylacetate (cis-5D) (Table 1, sample 1), 10 ml of the previously prepared hexane solution are added to the solution of the first three components prepared in Example 1 cis-5DA with a concentration of 0.005 mg / ml.

Similarly, mixtures with a different amount of components are prepared.

vushki. Traps are placed on the cotton floor no closer than 50 m from the edge, at an equal distance from each other (30 m), in one or two rows, the distance between which is at least 150 m, at a height of 10 cm above the vegetation level. Each sample was laid in triplicate.

The results of field tests are given in table 1.

From the data obtained it follows that the four-component mixtures effectively attract male scoops in the following quantities, mg:

CIS-5-TDA 0.75-1.71

CIS-9-TDA 0.09-0.75

CIS-7-GDA0.02-0.50

CIS-5-YES0,0002-0,0005

or when converted to wt.% this is:

CIS-5-TDA37.5-85.5

TsIS-9-TDA4.5-37.5

CIS-7-GDA1.0-25.0

CIS-5-DA0.01-0.025

From the table. it is seen that the addition of cis-5-TDA and cis-9-TDA to the composition of the known mixture up to about 1-25% cis-7-GDA and 0.01-0.025% CIS-5-YES leads to a synergistic effect. In addition, the vidos and the specificity of capture of male exclamation scoops are increased. 0

The use of an attractant to control the spread and number of insects significantly reduces the use of insecticides, and using them to control insects by trapping in attractant traps or by disorientation eliminates the use of insecticides,
