Muga Silkworm

Local name: Muga

Scientific name: Antheraea assama 

Family: Saturnidae

Host plant: Som and Sualu. Secondary host plant: Mejankari, Dighloti, Bagri and Bajramani

Muga Silkworm

Diseases:

1.     Pebrine:

      Pebrine cause by a protozoa namely Nosema bombycis.  The larva of muga silkworm generally got infected from the shell of the eggs. This way this disease is inherited from the infected mother. This disease may also infected leaves from host plants. When infected, the larva becomes weak and the silk glands are not properly developed.

Control:

a)     The disease can be controlled by keeping the live cocoon in a temperature of 34⁰ C at the prepupal stage for about 16 hours.

b)     Another method of disease control is heating the eggs after deposition in 40⁰C in a hot water bath for 20-30 minutes.

2.    Flacherie: 

      It is caused by virus followed by a secondary bacterial infection. Locally this disease is known as “Mukhlaga”. This disease is commonly seen in muga-rearing farm during summer. In this disease, infected larva die soon and sometimes entire brood is completely destroyed. 

Control:

a)     To control this disease, overcrowding of the larvae must be prevented.

b)     Only disease free seeds should be considered for rear.

Life cycle:

The life cycle of Muga silkworm consists of four distinct stages. These are 1. Egg (কণী)   2. Larva (পলু) 3. Pupa (লেটা)  4. Moth (চকৰী). To complete the life cycle it takes 48-52 days in summer and 145 – 150 days in winter.

Amazing plants in the World

        The term "amazing plants in the world" refers to plants that possess unique and striking features, such as unusual shapes, vibrant colors, or exceptional survival abilities. Some examples of amazing plants include the Venus Flytrap, a carnivorous plant that captures insects for nutrients, and the Rafflesia, a rare and endangered plant with the largest single flower in the world. Other examples include the Corpse Flower, which has the largest unbranched inflorescence in the world, and the Slipper Orchid, with its distinctive slipper-shaped petals. These plants are found in various parts of the world and continue to fascinate botanists and plant enthusiasts.

Parasitic plants

    Parasitic plants are a type of plant that derives nutrients and water from another plant, called the host plant, rather than from soil. These plants have specialized structures, such as haustoria, that allow them to tap into the host plant's vascular system and obtain the necessary resources. Example of parasitic plants-

Dodder plant

1. Dodder plant (Common name),

      Scientific name: Cuscuta reflexa Roxb.

       Family: Convolvulaceae

Dodder are a group of over 150 species in the genus Cuscuta. Dodder is a leafless, parasitic weed that relies on its host for survival. These species have a wide variety of host plants, including landscape and nursery grown ornamentals.

Indian Pipe plant 

2. Indian Pipe plant (Common name)

      Scientific name: Monotrapa uniflora

      Family:  Ericaceae (Family)

Insectivours plants

    Insectivorous plants, also known as carnivorous plants, are plants that obtain essential nutrients by capturing and digesting insects and other small animals. These plants typically thrive in nutrient-poor soil and have adapted to obtain necessary nutrients by producing modified leaves, stems, or roots that trap prey. Examples of insectivorous plants-

Design for Raising a Garden

 The design of your garden should be tailored to your space, climate, and personal preferences. Here are key considerations for an effective garden design:

1. Layout Planning

Create a detailed plan that includes pathways, planting beds, and focal points.

Consider using raised beds to improve soil quality and drainage while making maintenance easier.

2. Plant Arrangement

Group plants with similar water and sunlight needs together (known as companion planting).

Use layers (tall plants at the back or center with shorter ones in front) to create depth.

3. Incorporate Hardscaping Elements

Include paths made of stone or gravel for accessibility.

Add benches or seating areas for relaxation.

4. Water Features

Consider adding ponds or fountains to enhance tranquility and attract wildlife.

5. Seasonal Interest

Choose a mix of plants that provide color throughout different seasons—spring blooms, summer foliage, fall colors, and winter structure.

6. Sustainability Practices

Implement organic gardening techniques by using natural fertilizers and pest control methods.

Consider native plants that require less water and maintenance.

7. Maintenance Considerations

Plan for easy access to all parts of the garden for regular upkeep.

By thoughtfully selecting plant materials and designing your garden layout with these principles in mind, you can create a beautiful and sustainable outdoor space that enhances your living environment while providing enjoyment throughout the year.
