P Name of the School : Name of the Subject : Biology Name of the Unit : Agriculture away of life Topic : Different types of pest and pest control methods CURRICULAR STATEMENT By observation, communication drawing the child learns about the different types of pests and pest control methods CONTENT ANALYSIS Terms Quickwilt, Anthrax, Avian fly, brown, plant hopper, fruitfly, bugs, leafroller, beetles, tabacoodecoction, Kernel suspension, Trichocards, psendomonas, trichogrema, wasp Facts è Pests cause reduction of agricultural yield è Pests which affects various crops harmfully è Agriculture will be become economical only if the plants like blight disease, quickwilt disease, mosaic etc. è Their are many disease that affect the plants like blight disease, quickwilt disease, Mosaic etc.
- 2. è Brown Plant hopper is the pest which infects paddy. è Fruit fly which affects the vegetables è Mechanical, biological, and chemical pest controls are the main types of pest control. è Picking pests using hand is Mechanical control è Killing pests using natural enemies is a biological control. è Chemical pesticides cause numerous environmental problems. è In Mechanical control bugs were destroyed by placing burning torches in the field. è Trichocards are cards containing eggs of an insert card trichogremma. Concept 1. Agriculture will become economical only if the pests are controlled effectively. 2. In our early days pesticides did not cause any environmental pollution but today the pesticides are became very harmful and are accumulate in our human body and cause many disease. In order to destroy the pests like leafroller, water containing decayed fish was sprayed to attract the predators of this worm fish was sprayed to attract the predators of this worm.
- 3. * Enables the pupils to acquire the following ideas. è Factual knowledge about different types of pests and pest control methods. 1. Recalling new terms like fruittly, brown plant hopper, aphid, bugs, beetles, leafroller, coconut mite, stemborer etc. 2.

Which are the pests that infectrice? 3. Which is the pests infects vegetables? 4. Coconut bite affects which crops? Group Discussion lead by teacher Ther are many types of pests cause the reduction of agricul-tural yield and they causes many diseases stem borer infects rice, fruitfly infect sall vegetables, coconut can be infected by coconut mite Aphid also infectsrice. All those Pests are very Stem borer, Abid, fruitfly, coconutmite Stemborer, Aphid Fruitfly Coconut bite
- 6. harmful to our crops and they reduce air agricultural yield. Agriculture will become economical only if the pests are con-trolled effectively. Activity - II Teacher divide the pupils into groups and gives the chart shows the different types of pest control METHODS OF PEST CONTROL 1. Mechanical control è Picking pests using hands Here bugs were destroyed by placing torches in the field called light trap. Fordestroying leaf roller with decayed fish sprayed beetle sticks are used to picking beetles. 2. Biological control è Killing pests using their natu-ral enemies eg: trichocards. è These are cards containing egg of an insect trichogremma belonging to the family of wasp. 3. Chemical control è pests controlled using chemicals eg-DDT, Malathion.
- 7. Indicators 1. What are the different method of pest control? 2. How pests are controlled by the Mechanical Method? 3. In which method chemicals are used to control pests? 4. How pests are controlled by the biological method? 5. What is trichocards? Group Discussion lead by the teacher The different methods of pest controls are mechanical, chemical and biological control By using mechanical con-trol bugs were destroyed by placing torches in the field and decayed fish was sprayed to destroy the leaf roller this was done to attract the predators of this worm. Chemical are used to control pests in chemical method killing pests using natu-ral enemies in biological control method eg: trichocards. Mechanical, Chemical, Biological Picking pests using hands in Mechanical Method Chemical method Killing pests using their natural enemies eg: trichocards There are cards containing egg of an insect called trichogremma belonging to the family of a kind of wasp.
