Synthesis and Actions of Juvenile Hormones In Insect Development (MS Power…Saramita De Chakravarti
A morphogenetic hormone.
Has multiple functions and a primary role of JH in insect development is to modulate ecdysone action.
Maintains the current commitment of the tissues and cells whereas ecdysone causes both predifferentiative and differentiative cellular events that are necessary for the moult.
When JH is present, a moult to a larval stage ensures.
If JH is absent at the onset of the moult, morphogenesis occurs.
Further studies and researches are still going on that can elucidate new
This is our powerpoint presentation about the Hypothalamus, its function, what hormones it secretes and its main role in our body. This also has info about the Pituitary Gland, the hormones it releases and its function in our body.
Welcome to my presentation on the intricate world of the insect thorax! Delving into the fascinating realm of insect anatomy, my presentation offers an in-depth exploration of the structure, function, and significance of the thorax in the insect kingdom.
Designed with meticulous attention to detail, this presentation is a culmination of extensive research and a passion for entomology. It's meticulously structured to provide a comprehensive understanding of the thorax, a crucial part of an insect's anatomy governing its movement and vital physiological functions.
Featuring detailed diagrams and clear explanations, I've endeavored to simplify the complexities of the insect thorax, making it accessible to both enthusiasts and experts in the field. The visually engaging diagrams included in this presentation aim to elucidate the nuanced components and mechanisms of the thorax, providing a visually stimulating and educational experience.
This presentation reflects my dedication to creating informative and visually appealing content, aiming to contribute to the understanding of entomology and the marvels of the insect world. As an uploader, I take pride in presenting information in an engaging and structured manner to facilitate learning and appreciation for the intricacies of insect anatomy.
I invite you to explore this presentation, and I hope it serves as an insightful and valuable resource for anyone eager to learn about the remarkable structure of the insect thorax.
This Presentation is all about Ecdysone Receptor Agonists. All points are explained by diagrammatically. If you need any help about this topic, then mail me on mzeeshan_93@yahoo.com

Hey, this is my BSc assignment which will help you. It contains the basics about sericulture. I will provide you with a brief about sericulture as well.
Sericulture, also known as silk farming, is an ancient practice that involves the cultivation of silkworms for the production of silk. It is a labor-intensive process that requires meticulous care and attention at every stage, from selecting healthy silkworm eggs to the final processing of silk fibers. Sericulture has a rich history that spans thousands of years and has been a significant part of various cultures around the world.
The origins of sericulture can be traced back to ancient China, where it was initially kept as a closely guarded secret. The Chinese closely guarded the production techniques and methods, as silk was considered a valuable commodity and a symbol of wealth and luxury. However, the art of sericulture eventually spread to other parts of Asia and later to Europe and the rest of the world.
The sericulture process begins with the careful selection of silkworm eggs. Healthy and disease-free eggs are chosen to ensure the quality of the silkworms. These eggs are then incubated under controlled conditions until they hatch into tiny silkworm larvae. The larvae are then placed on specially prepared trays and provided with a diet consisting mainly of mulberry leaves, which are the primary food source for silkworms.
Mulberry trees, scientifically known as Morus spp., are cultivated in large quantities to sustain the silk production industry. The leaves of the mulberry trees are rich in nutrients, making them an ideal food source for the silkworms. The silkworms feed voraciously on the leaves, growing rapidly and shedding their skin multiple times in a process called molting.
After several weeks of feeding and molting, the silkworms reach their final stage, known as the cocooning stage. During this stage, the silkworms secrete a protein substance called fibroin, which is used to spin their cocoons. The silkworms create a protective covering by spinning a single continuous silk thread around themselves. This spinning process takes about two to three days, and the resulting cocoon is composed of a single thread that can measure several hundred meters in length.
To obtain the silk fibers, the cocoons are carefully harvested. However, to prevent the silkworms from breaking the silk thread, the cocoons are usually subjected to a process known as stifling. Stifling involves heating the cocoons or exposing them to steam to kill the silkworms inside. This process also makes it easier to unravel the silk thread from the cocoon.
After stifling, the silk thread is carefully unwound from the cocoon. This process is called reeling, and it requires skill and precision to ensure the quality of the silk fibers. Several strands of silk thread are combined to create a stronger and more durable silk yarn. The yarn is then cleaned to remove any impurities and twisted into a usable form.
