Insects
Characteristics :
rigid or articulated envelope that supports and protects the soft tissues of certain animals.
invertebrate animals having a segmented body, jointed limbs, and a shell of chitin that is shed periodically
- Pair of antennae
paired appendages used for sensing in arthropods. Antennae are connected to the first one or two segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments.
curved arrays of microscopic lenses. Each tiny lens captures an individual image
Different species
A pray mantis is an insect that has a long body with strong forelimbs shaped as if the insect is in a praying position.
An activity that the learner could do for a pray mantis is to have the learners count the number of legs that the pray mantis has and to then write the number of how many legs it has.
A butterfly is an insect that has large colorful wings and feed of the nectar of flowers. They are only awake throughout the day.
An activity that the learners can do in class is coloring two wings and cutting them out and pasting them on a black ice-cream stick. Then taking two black pipe cleaners and twisting them at the ends and then also gluing them to the top of the ice-cream stick
An ant is a small six-legged insect that lives in big colonies with a queen, and they are wingless, only fertile adults have wings.
An activity the learners can do is cutting apart an egg tray and gluing 3 pieces of the egg tray together and paint it brown and then take 3 brown pipe cleaners and cut them in half and then stick 3 pipe cleaners on the left and them 3 pipe cleaners on the right for legs and then stick on eyes in the front.
A spider is an arachnid {scientific name for a spider.} which means that is has eight legs, fangs and an unsegmented body.
An activity the learners can do is gluing the eight legs on to the body but as they are gluing, they are counting how many legs there are on the spider.
How insects can harm us
The 2 greatest risks from most insect stings are allergic reaction and infection. Bites from some insects can also cause illnesses, such as Lyme disease from ticks, scabies from mites, and malaria from mosquitoes in certain parts of the world.
it is the breeding, feeding and defecating habits of these insects that contaminate food. Potential harm includes the following: Contamination of foodstuffs and goods; resulting in serious loss of valuable stock. Damage to processing machinery due to the buildup of food product in machinery caused by the stored product insects.
These insects cause damage by feeding, and some can also transmit diseases to plants causing them to be unsellable or even causing the plants to die.
Bugs, including mosquitoes, ticks, fleas, and flies, can spread diseases such as malaria, yellow fever, Zika, dengue, chikungunya, and Lyme. While some cases are mild, these diseases can be severe and have lasting consequences.
How insects help us
Many insects, principally fly larvae, secret enzymes directly into the carrion, producing liquefaction of the tissues
Insects can supplement traditional feed sources such as soy, maize, grains and fishmeal. Insects with the largest immediate potential for large-scale feed production are larvae of the black soldier fly, the common housefly and the yellow mealworm.
Flowers produce a sugary liquid called nectar which many insects consume on a large basis. When insects land on a flower, pollen grains tend to stick to their bodies. The insect then moves from one to another flower of the same species, pollen gets transferred to the stigma of flowers and hence causing pollination.
many cultures worldwide, traditional medicine has used insects for a long time to treat stomach aches, respiratory issues, and wound healing. However, most of the research on the functional significance of edible insects has been on their ability to act as antioxidants in cell models or in vitro (32).
