ABSTRACT This investigatory project was conducted primarily to determine the effectiveness of “Sapal” in restraining bean weevil for longer storage of leguminous seeds. Simple process was undertaken. The materials were prepared before performing the experiment. The 150 grams of mongo seeds were used as the experimental set-up and 150 grams for control set-ups. One piece of mature coconut was grated and dried, 75 grams of “Sapal” was mixed with 150 grams of mongo seed, and also with 150 grams of string bean seeds. The ratio of mixing was 2:1 seeds and “Sapal”. After mixing, it was placed in separate sieves and allowed to dry under the sun for 6 hours. Then, the experimental seeds were placed in separate jars properly labeled; likewise with the jars of the control separately placed and also properly labeled. The bottles were kept in a cabinet seed bank safe to avoid being accidentally destroyed by people and animals. The seeds were observed weekly and whatever observations noticed for a period of one month were recorded. Result of the study showed that using “Sapal” as Weevil Repellant in Storing String Bean and Mongo Seeds is effective. The researchers concluded that “Sapal” is an effective medium in preventing the attack of weevil on beans and mongo during storage.

Legumes are one of the most valuable plants grown in the country. They do not only produce food for man and animals but also contribute to the fertility and improvement of the physical condition of the soil. Legumes are plants that bear flowers shaped like a butterfly and which produce seeds enclosed in pods. Legumes are highly nutritious. The seeds of these plants are an alternate source of food protein especially among Filipinos who belong to poverty level. They are also used as medicine in reducing cases of beriberi. They are easily prepared as food and easily digested. As animal feed, they serve as additives that provide protein. Their pods are used as green feeds and an excellent food for fattening and lactating animals. The bean weevil (Callosbruchus chinensis L.) is a very serious pest attacking bean seeds during storage. This insect reduces the quality of seeds and its viability, making it unfit for human consumption and propagation. One of the measures commonly used to control this pests is the used of chemical insecticide. However, some farmers could not afford to treat their products due to high cost of insecticides which also leave toxic residue to the treated seeds making them unfit for human consumption. These observations and problems prompted the researchers to investigate and determine the effectiveness of using “Sapal” as weevil repellant for string bean and mongo seeds.


The coconut palm, Cocos nucifera, is classified in the family Palmaceae (palm).It is one of the most valuable trees of the palm family, and the most widely distributed of all palms. The coconut palm is found in all tropical regions, even in the most 6 isolated shores, where the floating seeds were probably carried by ocean currents. It also grows in the wild in the southern part of Florida. The original habitat is not known. The tree has grown in tropical Asia and the Malayan islands since prehistoric times, and it may have originated in those regions.
Mongo has a protein content of 20-28% which is about three times that of cereals. Its seeds are easily utilized in a number of ways. They may be boiled and eaten with sugar and milk or mixed with sotanghon.


The materials used were mongo seeds (300 grams); 150 grams for experimental set up and 150 grams for control set up; bean seeds (300 grams); 150 grams for experimental and 150 grams for control set up; Sapal – 150 grams; and empty glass jars, 4 pieces.



The following are the data gathered from this study:
Table 1
OF “SAPAL” IN CONTROLLING WEEVIL Materials | Experimental Set-up | Control Set-up | | 1st Week | 2nd Week | 3rd Week | 1st
Week | 2nd
Week | 3rd Week | Bean Seeds | 0 | 0 | 0 | 10 | 18 | 25 | Mongo Seeds | 0 | 0 | 0 | 12 | 16 | 28 |

Table 1 shows the comparisons and evaluations on the effectiveness of sapal in controlling weevil. Within one month, Sapal was applied on bean seeds and mongo seeds at 2:1 ratio (2 part seed and 1 part sapal). As the number of weeds increased the presence of weevil also increased in the control set-ups. They were directly proportional. The effectiveness of sapal is 100%effective.

Table 2

Control Set-up | Experimental Set-up |

Material | No. of seeds damaged (grams) | No. of seeds undamaged (grams) | No. of seeds damaged (grams) | No. of seeds undamaged (grams) | Mongo Seeds |
17 |
133 |
0 |
150 | String Bean Seeds |
15 |
135 |
0 |
150 |
Table 2 shows the effect of “Sapal” in controlling weevil. For the period of one month of storing the string bean and mongo seeds, there are only a small number of seeds damaged as shown in table 2 while in the experimental set-up all of the seeds were undamaged.


Based on our study, we are able to find out that using sepal is effective for legumes to control bean weevil. And within the period of one month of longer, “Sapal” can protect mongo and bean from bean weevil. Therefore, sapal has a high potential of being a sufficient source in the storage of leguminous seeds.

Lumalabo na ang paningin ko at sunod sunod na ang pagpatak ng aking mga luha. Mga luhang nagpapahiwatag sa sakit na aking dinaramdam ngayon. At sa bawat pagpatak ng luha ko’y siya ring pagbalik ng ala-ala naming dalawa. Mga ala-ala kung bakit mahal ko siya. Tanggap ko na. Alam kong hindi kami para sa isa’t isa. Wala na siya. Tuluyan na niya akong iniwan dahil sa isang mababaw na rason. Teka lang, tanggap ko na nga ba? Hindi ko alam. Ang tanging alam ko lamang ngayon ay parang namamatay na ang katawan ko.

...attachment that resists separation. “Adhesive” as a general term includes cement, mucilage, glue, and paste—terms that are often used interchangeably for any organic material that forms an adhesive bond. Inorganic substances such as portland cement also can be considered adhesives, in the sense that they hold objects such as bricks and beams together through surface attachment, but this article is limited to a discussion of organic adhesives, both natural and synthetic. ( Fish glue is often made by heating the skin or bones of fish in water. It can also be made from part of the fish’s air bladder which, in the case of glue made from sturgeon, is called isinglass. Adhesives made from fish, as well as hide glue made from other animals, were sometimes used in ancient Egypt. They are still used in art, for shoe and furniture repair, and to preserve old manuscripts. Hide glue is typically manufactured from the skin of non-oily fish. During medieval times in Europe, fish glue was often used to repair animal-based sheets called parchments, which were used for writing. It was also used in painting materials by some artists in China. Paintings and drawings were often coating with fish glue in the 1800s. While the glue by itself is typically brittle, it can be used along with other materials to restore paintings. Artistic uses for fish glue include its application as a binder, glazing agent, or protective coating for paintings.......

Eating Paste, Is It Delicous? eat glue Posted by Ryan Pilling on Mar 2, 2011 in Interesting Facts | 1 comment In the exciting world of adhesives, glue is the organic side of things. Technically, for something to be a true “glue” it will get its sticky quality from an animal or vegetable ingredient. The classic example is sending an old horse to the great glue factory in the sky. In fact horse hooves, along with bone, hide, and connective tissues, provide collagen as the main ingredient for glue. (in all mammals, including you dear reader, over 25% of the protein content is collagen) The process of turning pony toes into glue is, to boil it down, essentially… boiling it down. The collagen leaks out in a jelly-like form, is collected, and ground into powder. When you’re ready to make antique furniture, you mix it with a bit of water, heat it up, and you’re ready to brush it on your joins. Collagen glue like that has been used for at least 8000 years, and has only been replaced by chemical adhesives for common use in the past century. Vegetable glue, commonly called paste, is an even simpler recipe: starch and water. The starch most commonly used is corn starch, but white flour works as well. When sticking things together, the best adhesive is one that shares chemical properties of the items you want to make stick. That’s why paste works so well with paper. The starch, which is a carbohydrate, is similar to the carbohydrate cellulose that forms the paper. So animal glue is......

Classification of Adhesives

...Classification of Adhesives: There are two main classes of adhesives: thermoplastic and thermosetting. Thermoplastic sets either my loss of solvent or by cooling. It will soften again by applying the solvent to the glue line or by re-heating. Thermosetting sets and solidifies through a chemical reaction and is irreversible. Adhesives that set at room temperature are known as 'cold-setting' and those that require heating up to a temperature perhaps in the case of pearl glue 40 and others up to 100 degrees C are known as 'hot-setting'. Types of Adhesives: Animal. Known as scotch glue (yes glue!), pearl or hide glue. Made from the hides, hoofs and bones of animals. Available now in cake or more likely supplied in small beads. It is essential for restoration work, veneering and other applications where compatibility with original artefacts is needed. Used extensively in the musical instrument industries. It is for internal use only and has high gap filling properties. Fish glue is also available which is made out of fish offal and skins. Good for small repairs. Not recommended for structural work. Casein. Manufactured from soured, skimmed milk curbs which are dried and crushed into a powder form. General joinery and woodwork use. It may stain some hardwoods and oak is particularly prone to darken. To use the powder it is mixed with cold water into a smooth creamy paste. Developed in WW2 for the manufacture of the Mosquito plane which was largely......

...a student should have is glue. In our society, we rely on glues for it have innumerable uses. Skim milk is a milk wherefrom the cream is extracted. It is loaded with various nutrients -   protein, calcium, phosphorous, vitamin D and vitamin A. These nutrients maintain the building of teeth, body and muscles. The Protein in skim milk comprises the complete amino acid a human needs regularly, effecting the skim milk to be a source of high- quality, total protein. Knowing that skim milk contains protein, it is proved that glue can be made from casein – the protein in milk. The casein protein is also used in fabricating various goods, including fabrics, adhesives, plastics, and protective coatings. This study aims to make homemade glue by means of coagulation and precipitation. Results show that skim milk can be use as an alternative for glue. BACKGROUND OF THE STUDY Poverty is one of the major problems the world is facing today. Not every student could afford to buy branded glue and not every store opens 24 hours. It is a problem for some people in buying glue. It might not be applicable for all, but in some instances, it is true. The researchers wanted to find a way to help solve this problem.

...Chapter 1 INTRODUCTION A.Background of the study The use of adhesives offers many advantages over binding techniques such as sewing, mechanical fastening, thermal bonding, etc. These include the ability to bind different materials together, to distribute stress more efficiently across the joint, the cost effectiveness of an easily mechanized process, an improvement in aesthetic design, and increased design flexibility. The researcher will make glue out of milk to improved the stickness of milk. An adhesive is any substance applied to the surfaces of materials that binds them together and resists separation.Adhesives may be found naturally or produced synthetically.These are then organized into reactive and non-reactive adhesives, which refers to whether the adhesive chemical reacts in order to harden. Alternatively they can be organized by whether the raw stock is of natural or synthetic origin, or by their starting physical phrase. Adhesive is classified in different material like glue,cement, beewax etc.Disadvantages of adhesive use include decreased stability at high temperatures, relative weakness in bonding large objects with a small bonding surface area, and greater difficulty in separating objects during testing. The researcher chooses this project because I'm interested of this topic. I know that this project is already been done by other people.Adhesive play the important role of the stickness of the raw materials to improved the joined......

Diy: Wrist Corsage for Debut indicate a special person on a special day. By the way, most of your friends are turning eighteen. Why not give them a homemade corsage? To make them feel even more special. How? Listen for the next few minutes and you will learn how to make this 10-step DIY or do it yourself wrist corsage. For the corsage, you’re going to need some simple basic DIY ingredients like stapler, glue gun with the glue stick, and fabric ribbon for about 12” by 1.5” for your bow. You’ll also need a beaded bracelet or any decorative bracelet where you can attach your final corsage. Finally, you need to add some decorative flowers and leaves. I think the cutest flowers for a corsage are mini-roses, paperwhites, cherry flowers or any artificial flowers of your own choice. Now that we have our materials before us, we’re going to start by gluing the fabric ribbon together at the ends to have a loop and staple it at the center to make a two-point bow. Do this with the other ribbon in a like manner. Attach the bow at the top of the other in an opposite direction to make a four-point bow. The next step we’re going to do is to take at least three pieces of any artificial leaves and glue them above the bow in a triangular distribution. Now, it’s time to begin adding in with your flowers. Since the roses take up the most space, I’ll add those first by stripping off the leaves and glue them at the top. (Whenever I gave flowers to my grandma, I always give her white roses because white roses are often......
