Description

Technical Field

[0001] The present invention belongs to the technical field of termite control and relates to a preparation process of a termite control composition. Background Art

[0002] Termites, also known as insect lieutenants, belong to the phylum Arthropoda, class Insecta, order Isoptera. They live a social life similar to ants, and their social classes are queen termite, king termite, soldier termite, and worker termite. Although termites and ants are generally both called ants, in terms of taxonomic status, termites belong to the lower semi-metamorphic insects, while ants belong to the higher holometabolous insects. Judging from fossils, termites may have evolved from ancient orthopteran insects and first appeared in the Permian period 200 million years ago. People may mistakenly think that termites are a kind of ant, but in fact, termites and ants are two different species. Termites are soft and small in body, usually long and round, white, light yellow, reddish-brown to black-brown. The head is prognathous or hypognathous and can move freely. The antennae are beaded, the abdominal base is thick, and the front and rear wings are of equal length; the antennae of ants are geniculate, the abdominal base is slender, and the front wing is larger than the rear wing. What ancient Chinese books called ants, flying ants, termites, etc. were all confused with ants. The name "termite" began to appear in the Song Dynasty and was determined as an alternative name for termites. Termites are distributed in tropical and subtropical regions and feed on wood or cellulose. Termites are a kind of polymorphic, social insects with strict division of labor. Once the group organization is damaged, it is very difficult to survive. More than 2,000 species are known worldwide. In China, except for the family Mastotermitidae which has not been found yet, the other 4 families are all present, with a total of more than 300 species. The distribution range is very wide.

[0003] Termites are a very harmful insect. Railway sleepers, buildings, stored materials, forest trees and fruit trees, and field crops will all be eaten and damaged by termites. Especially for the dams of reservoirs and rivers, and the trees in subtropical regions, the harm is extremely serious.

[0004] For example, a Chinese patent document discloses a point-to-point termite control bait and its application [Application No.: CN201310043383.6; Publication No.: CN103081952B]. The bait, by weight, includes: 2-4 parts of bamboo chips, 2-4 parts of mushroom stalks, 1-3 parts of aloe roots, and 0.5-2 parts of termite nests. The present invention also discloses a preparation method of the point-to-point termite control bait and its application in the preparation of a termite monitoring device or a termite killing bait. Although the bait may have a certain attracting effect, the rainproof effect of the control bait is poor.

[0005] Based on this, we propose a preparation process for a termite control composition, which has good attracting effect and strong rain-proof performance. By combining sodium molybdate, sodium tungstate and pathogenic bacteria liquid, it can quickly infect and kill individual termites and the whole termite nest, with a high lethality effect. Through the cooperation of an extrusion mechanism and a cutting mechanism, it can quickly form a usable surface block. Through the cooperation of a transfer box, a placement box, a forming mechanism and a conveyor track, it can quickly extrude the surface block into a hemispherical shape, which is placed outdoors and is not easy to loosen in the rain, and can be stored for a long time in the rain state to ensure termite feeding. Through the cooperation of a steam oven and a drying mechanism, it can quickly steam and effectively dry the surface block, ensure more water absorption, and at the same time cooperate with a fan to effectively use heat, which is more environmentally friendly and energy-saving. Through the cooperation of a liquid injection tank and a liquid injection mechanism, it can inject the bacteria liquid into the dry surface block to obtain a bacteria liquid surface block. At the same time, the bacteria liquid is located inside the dry surface block, is not easy to be washed away by rain, has a longer storage time, and can kill termites more effectively.

[0079] The preparation process steps are as follows:

[0080] Step 1, raw material drying: The bamboo sawdust, eucalyptus bark, bagasse and termite nest debris are dried to obtain dried materials;

[0081] Step 2, dried material pulverization: The bamboo sawdust, eucalyptus bark, bagasse and termite nest debris are pulverized to obtain powder materials;

[0082] Step 3, mixing and stirring: The powder materials of bamboo sawdust, eucalyptus bark, bagasse and termite nest debris, flour, polymer binder and yeast powder are introduced into the stirring and fermenting machine 1 according to a certain weight ratio, and an aqueous solution of sodium molybdate and sodium tungstate is added for mixing to obtain dough;

[0083] Step Four, dough fermentation: Let it stand and ferment for a period of time, which is 2 - 3 hours;

[0084] Step Five, cutting and forming: Take out the fermented dough and put it into the inner part of the feed hopper 15. The output shaft of the extrusion motor 21 drives the extrusion screw shaft 16 to rotate through a sprocket pair, and the fermented dough inside the extrusion screw tube 17 is extruded from several extrusion tubes 18. The output shaft of the cutting motor 26 drives the lead screw 27 to reciprocate through a pulley pair. The lead screw 27 drives the moving slider 28 to reciprocate on the slide rail 29. The moving slider 28 drives the moving plate 24 to reciprocate. The moving plate 24 drives the cutter 25 to reciprocate at the outlet of the corresponding extrusion tube 18 to cut the extruded dough into equal-length dough blocks. The dough blocks fall on the slope 23 and slide to above the holding tray 19. The dough blocks are put into the placing tray inside the transfer box 4, and then the placing tray with the dough blocks is placed inside the placing box 5. Then, the placing tray with the dough blocks inside the placing box 5 is placed on the feeding track 31. The output shaft of the feeding motor 30 drives one of the rotating shafts of the feeding track 31 to rotate intermittently through a sprocket pair, thereby driving the feeding track 31 to move intermittently until it is directly below one set of forming clamping rods 35. Two symmetrically arranged electric push rods 34 drive the corresponding forming boxes 33 to close relatively, clamping the evenly placed dough blocks on the placing tray inside to form hemispherical dough blocks. The output shaft of the forming motor 36 drives the rotating frame to rotate and move by an angle. One set of forming clamping rods 35 holding the hemispherical dough blocks rotates to directly above the conveying track 7. Two symmetrically arranged electric push rods 34 drive the corresponding forming boxes 33 to open relatively. The hemispherical dough blocks fall between the evenly distributed dividing baffles 37 above the conveying track 7. One of the other set of unclamped forming clamping rods 35 rotates to above the placing tray with the dough blocks;

[0085] Step Six, steaming and baking of hemispherical dough blocks: The hemispherical dough blocks are conveyed to one side of the steaming and baking oven 9 through the conveying track 7, and the hemispherical dough blocks are placed inside the steaming and baking oven 9 for steaming and baking to obtain cooked dough blocks;

[0086] Step Seven, drying of cooked dough blocks: Place the steamed cooked dough blocks in the placing grid. There is a heating wire inside the heating box 46. After starting, the fan 8 extracts the high-temperature steam inside the steaming and baking oven 9 through its upper air outlet end 14, filters it through the water filter to obtain dry high-temperature air, enters through the air inlet 13 of the fan 8, and is injected into the heating box 46 through the air outlet of the fan 8 to form hot air, which is blown into the drying box 45 to dry the steamed cooked dough blocks inside the placing grid to obtain dry dough blocks;

[0087] Step 8, injecting the bacterial liquid: When the dried noodle block moves to the lower part of the corresponding liquid outlet pipe 43, the lead screw assembly 39 drives the installation box 41 to move downward, the liquid outlet pipe 43 is inserted into the dried noodle block, the liquid injection pump 42 is started, the pathogenic bacterial liquid in the liquid injection tank 11 is pumped into the liquid storage cylinder 40, and then injected into the dried noodle block to obtain a noodle block with bacterial liquid.

[0088] Step 9, placing the noodle block with bacterial liquid: Place the noodle block with bacterial liquid in the wild where termites appear. When the noodle block with bacterial liquid is used in the wild, it will not loosen even under sun and rain, and the active ingredients will not be lost.

[0089] In Step 3, the weight ratio of the powder of bamboo shavings, eucalyptus bark, bagasse and termite nest debris, flour, polymer binder, yeast powder, and the aqueous solution of sodium molybdate and sodium tungstate is 40:20:15:10:200:2:2:100.

[0090] In the aqueous solution of sodium molybdate and sodium tungstate in Step 3, the weight ratio of sodium molybdate, sodium tungstate and water is 12:5:100; the bacterial liquid in Step 8 is a pathogenic bacterial liquid prepared by mixing one of Xenorhabdus nematophila or Bacillus thuringiensis with water.

[0091] Example 2

[0092] Compared with Example 1, in Example 2, the weight ratio of the powder of bamboo shavings, eucalyptus bark, bagasse and termite nest debris, flour, polymer binder, yeast powder, and the aqueous solution of sodium molybdate and sodium tungstate is 40:20:15:10:200:1:1:100; other steps or ratios are the same.

[0093] Example 3

[0094] Compared with Example 1, in Example 3, there is no pressing and forming of the noodle block in Step 5 to form a hemispherical noodle block, and the cut noodle block is directly subjected to the steaming and baking in Step 6; other steps or ratios are the same.

[0095] Example 4

[0096] Compared with Example 1, in Example 4, Step 8 is omitted, and the dried noodle block is directly placed in the wild where termites appear; other steps or ratios are the same.

[0097] Example 5

[0098] Compared with Example 1, in Example 5, the aqueous solution of sodium molybdate and sodium tungstate in Step 3 is changed to directly use water; other steps or ratios are the same.

[0099] According to the solutions of Examples 1 - 5, take the same number of noodle blocks, and conduct indoor comparison experiments in four regions and simulated rain comparison experiments for one group:

[0100] Indoor comparative experiment conditions: A certain amount of termite workers were placed inside the experimental room and raised under the condition of a constant temperature of 24 - 26°C. After 48 hours, the feeding rate was visually observed and the death situation of the termites was checked every day. The number of days when all termites died was recorded. Each example had several groups, and the average value was taken. The experimental table is as follows (Table 1):

[0101]

[0102] Table 1

[0103] As can be seen from Table 1, among Examples 1 - 5, the formula of Example 1 is reasonable, and the feeding and lethal effects are the best.

[0104] Simulated rain shower comparative experiment conditions: Examples 1 - 5 were carried out. Spraying experiments and soaking experiments were conducted in the experimental room. Each example had several groups, and the average value was taken for observing the time when it became completely loose. The experimental table is as follows (Table 2):

[0105]

[0106] Table 2

[0107] As can be seen from Table 2, among Examples 1 - 5, the formula of Example 1 is reasonable, it is hemispherical, not easy to loosen when encountering water, and can be stored for a long time in the rain state to ensure termite feeding.

[0108] In summary, through the cooperation of the extrusion mechanism 2 and the cutting mechanism 3, the rapid formation of the usable dough piece is realized;

[0109] Through the cooperation of the transfer box 4, the placement box 5, the forming mechanism 6 and the conveying track 7, the dough piece is quickly extruded into a hemisphere and placed outdoors. It is not easy to loosen when it rains and can be stored for a long time in the rain state to ensure termite feeding;

[0110] Through the cooperation of the steam oven 9 and the drying mechanism 10, the dough piece is quickly steamed and effectively dried, ensuring that it absorbs more water. At the same time, in cooperation with the blower 8, the heat is effectively used, which is more environmentally friendly and energy - saving;

[0111] Through the cooperation of the liquid injection tank 11 and the liquid injection mechanism 12, the injection of the bacterial liquid into the inside of the dry dough piece is realized to obtain the bacterial liquid dough piece. At the same time, the bacterial liquid is inside the dry dough piece, not easy to be washed away by rain, has a longer storage time, and can kill termites more effectively.
