Description

DETAILED DESCRIPTION OF THE INVENTION This invention is a novel method for attracting and killing pine beetles and other harmful insects using a heavy oil in petroleum hydrocarbons that is used for lubricating oil containing aromatic compounds. This is the method of

Petroleum-based hydrocarbon oils such as gasoline, kerosene, and light oil are repellent to reptiles, but the heavy oil containing aromatic compounds traditionally used in lubricating oils* contains pine beetles and other insects. As a result of many years of experimentation, the inventor has newly discovered that the insect attracts and retains harmful insects, and the pest attracting method of this invention was completed based on this discovery.

Traditionally, most attractants have been thought to be volatile and ineffective unless the scent is diffused into the air.

Therefore, the base material easily evaporates and evaporates due to sunlight and high temperatures in the summer, so alcohols are added to it.

Volatile synthetic fragrances, sublimable organic acid solvents, etc. tend to scatter and disappear quickly, and as they are expensive substances, they have not been put to practical use.

Therefore, there has been a need for a neutral and stable base material that does not have these drawbacks, can be obtained in large quantities at low cost, and is not only an attractant but also has retention properties.

Although the attractant base oils of the present invention are nearly non-volatile, harmful insects can accurately locate them from a distance.Moreover, they are almost neutral and stable, and unlike acidic ones, they do not cause oxidative deterioration to the added attractant. It retains the scent and retains it, and even after the scent has dispersed, it exhibits its own attracting properties.

It has excellent attracting power in itself and does not attract any natural enemies.

Most of the harmful insects that do not show this reaction are not averse to this base material, so it can be an excellent attracting base material to which various additive attractants are added.

Also, since it is nearly non-volatile, empty soft drink cans can be used without the need for special traps that were previously required.

This attractive base oil can independently attract the giant insects, as well as the harmful insects that parasitize pine trees as shown in Table 1, and other harmful insects that parasitize pine trees. The purpose is to contain small amounts of various additive attractants that attract various kinds of harmful insects, to keep them for a long time, and thereby to attract kinds of harmful insects that could not be captured conventionally, and to open up a wide range of uses. It is.

*The petroleum hydrocarbons from which lubricating oils containing aromatic compounds obtained by further vacuum distillation of petroleum atmospheric distillation residual oil and various conventional processes are a mixture of countless compounds, and are generally Paraffin type.

Olefinic (thermal cracking, catalytic cracking, products).

Nandene type (cycloparaffin type).

Aromatic. Table 2 shows the proportions of each type of hydrocarbon in crude oil.

As shown in the table, light distillates contain a lot of paraffins and monocyclic naphthenes (cycloparaffins), but as the oil becomes heavier, it becomes monocyclic aromatic.

2-ring aromatic (naphthalene). The proportion of these aromatic compounds containing polycyclic aromatics such as three rings (fuenathrene) and aromatic rings and naphthenic rings is increasing.

This trend is common to all crude oils.

When we divided these distilleries from light to heavy distilleries sequentially and conducted experiments based on various materials over the years, we found that the capture rate suddenly increases when it comes to the heavy oil containing aromatic compounds. It increases.

This is because these soluble components have a composition of active ingredients, and the present invention is characterized by effectively utilizing their attractive properties and various advantages as a base material.

Of the above-mentioned soluble components, light lubricating oils contain some amount of light oil odor which is repellent to pests, so highly purified oils with odor removed can be used as attractant base oils.

The dissolved content, which corresponds to heavier lubricating oils, has no light oil odor, and
Since it contains many aromatic compounds, the conventional standard is 120 to 160.
A medium-refined, additive-free, machine oil-grade oil can be used as a sufficient attractant base oil by blending it or using it alone.

Highly purified versions of each dissolved substance are easy to smell, so they are used for harmful insects that are attracted to the added attractant, and those that are sensitive to scents, and most of them are inexpensive and refined to a medium level without additives. Conventional anti-friction oil specifications such as viscosity index and pour point do not have much effect on the insect trapping effect, so they are not included in the standards, and each solvent is used individually or with the addition of attractants. The ingredients can be used individually or in combination as appropriate.

The color tone only needs to be such that the results of catching insects at the bottom of the can can be seen through when used.

Antioxidants and preservatives may be used in these products.

Plants attract and attract insects through their aromatic components.

The material classification series includes alcohols, acids, ester aldehydes, ketones, phenols, hydrocarbons, lactones, and others, and various attractants and fragrances also belong to this series.

These are expensive and unstable, and many of them are susceptible to chemical changes or volatilization even if left exposed to sunlight, high temperature, or humidity, and some even attract natural enemies such as spiders, ants, and bees.

By adding a small amount of attractant to these harmful insects to this attracting base oil, which is almost stable, neutral, and retentive, it can be used to target natural enemies due to its natural enemy non-attractive properties, and to protect it from sunlight, high temperature, and humidity. It maintains its own attractive power even after the fragrance gradually disperses.

In this way, harmful insects that react to the attractive base oil are captured, but
Even substances that do not show any reaction will not abhor this base material, so add an appropriate amount of attractant to this, for example 0.0005.
~0.005, by mixing and blending individual items,
Harmful insects that could not be captured with conventional methods can also be captured with conventional methods.

Table 3 lists examples.

When the parasitic tree weakens and dies, borers fly in response to the essential oils and anaerobic fermentation products emitted from under the tree's skin, and fly to that hole to raise their larvae under the weakened skin. These insects have a habit of mating and laying eggs on the sand, and the insects that occur under the skin change slightly depending on temperature, enzymes, microorganisms, and other inertia, so insects also have this variety. It is inferred that by repeating this process since ancient times, it has developed the habit of flying to colored nives by detecting and reacting to them by smell and reaching the sand from a distance.

If you look into it, it's the color of the ama that reacts, for example, even if it's artificially synthesized by humans, it reacts and flies, so this is also used in the present invention, but the reason why it flies is because of the ama that insects like. In addition to being attracted to crabs, it is thought that one reason for this is that they are attracted by a rare nun that is not found in the forest.

The characteristics of such synthesized attractant compounds are that they are strong even in small amounts and some attract them from a distance, so it is a good idea to use them in combination to increase the catch.Also, in the present invention, the attractant base oil A trace amount, for example, a single species or two or more species, is added to heavy oil.
．． By adding about 00005 to 0.005, an excellent attracting effect can be exerted due to the synergistic effect of both.

The method of finding such attracting compounds is to choose one that seems to be effective based on experience, and place it on the sand of the parasitic tree at night. If it is effective, nocturnal insects will fly to the vicinity of the insect. The attractant compound of the present invention, which is observed to copulate and lay eggs in these nuns, was thus discovered.

These boring insects also fly to organic compounds that are not thought to be good for humans, and the way they fly changes subtly depending on the combination of attracting compounds, and the material classification of these attracting compounds The series may belong to alcohols, acids, nistoles, aldehydes, ketones, phenols, hydrocarbons, lactones, etc., or be made up of a complex mixture of these, but these do not necessarily show strong attraction. In some cases, effectiveness may be determined by experimenting with the method described above at night.

When using attractant base oil for pine beetle insects, the scent will be stronger and the results will be better if several species are placed in one place.Furthermore, a single scent may be used, but it is preferable to use several species. .

In the past, attractants and chemicals were used indiscriminately, but when capturing pine borers and other harmful borers, they fly to the weakened trees of parasitic plants to lay eggs and feed. Therefore, by setting this up, you can capture a dramatically large number of harmful insects at a low cost.

In order to prevent the decay and deterioration of the remains of insects that have jumped into each board and the organic substances they produce, use preservatives that are non-toxic and non-irritating to avoid rashes on the skin. Use preservatives that are permitted under the Pharmaceutical Affairs Law for use in cosmetics and other products used on the skin, but do not reduce their arch-attracting properties.

Permitted preservatives - benzoic acid and salts.

Salicylic acid and salts. Paraoxybenzoic acid ester.
