Method for fighting h. armiger and eustrotia candidula pests

专利摘要:
A slow release formulation of sex pheromones of insects, consisting of aldehydes, is herein described. The formulations herein described are employable for attracting and catching the insects in traps or for permeating the air in an infested area, in this way disturbing and preventing copulation.

专利说明:

The invention relates to chemical means of protecting the plant from insect pests, in particular, to methods for controlling the use of insect pheromone from sex.
The purpose of the invention is to increase the efficiency of the method by increasing the duration of the action of the sex pheromones of N. armiger and Eustrotia sapidula.
Sex pheromones of these types of pests include aldehydes Z-H-hexadecenal or Z-9-hexadecenal, which are easily oxidized by sunlight and air, which leads to a rapid loss of their effectiveness in attracting insects.
The duration of action of pheromones, including Z-15-hexadecenal or Z-9-hexadecenal, is achieved by converting them to bi-sulfite adducts, which are used in a buffer solution with a pH of 3.7-6.9.
Aldegvdny pheromone, being in the form of a bisulfite adduct, has a higher resistance.
The synthesis of bisulfite adducts is carried out in the usual manner used for the reaction of this type.
The buffer solutions used in the proposed method are well known.
Pheromones can be used in usual doses, for example, 2.5-30 g per hectare.
Example 1. A mixture of 0.9 g of Z-ll-hexadecenal and 2.25 ml of the saturated solution Od was stirred at room temperature until an insoluble compound had a waxy consistency. The mixture is stirred for another 1 h, after which the precipitate is filtered and washed successively with distilled water, ethyl alcohol and diethyl ether.

The yield is 1.3 g of the adduct, the IR spectrum of which contains bands of 3600-3200 cm corresponding to the associated OH group. The bands 2710 and 1730 cm, belonging to the IT group of the starting aldehyde, are absent.
Example 2. Thermal stability of bisulfite adduct.
0.35 g of Z-1J-hexadecenal or 0.3 g of its bisulfite adduct is introduced into dark glass vessels with a capacity of 2.5 ml. The vessels are sealed tightly and kept at 40 ° C.
To determine the amount of residual aldehyde, gas chromatographic analysis is used.
In tab. Figure 1 shows the thermal stability of Z-11-hexadecenal and the bisulfite adduct at.

Example 3. Petri dishes are placed in 100 mg of aldehyde (Z-11-hexadececenal) or 145 mg of its bisulphide fittic adduct. The cups are irradiated with a mercury lamp (D 320-400 nm) at 30 ° C.

The repetition of experiments is threefold. Example 4 Placed in a series of flasks of 1 g Z-P-hexadecenal bisulfite adduct, 100 g of a buffer solution with a certain pH value and 100 g of a mixture of equal amounts of xylene and n-hexane, as well as an antioxidant and a photo stabilizer.

The results are shown in Table. 4 shows that the bisulfite adduct traps uniformly distribute the pheromone for 60 days, and the effectiveness of the aldehyde trap decreases after 30-35 days.
Example 6. Example 5 is repeated.
In 12 polyethylene vessels with a volume of 1 ml with suitable polyethylene using vessels D, D, and D, 7.1 mg double corks are placed in each of them: Z-9-hexadeceno fo A in vessels A-, sulfite adduct and a 17 mg bisulfite adduct
