We grade 10 students were taken to Kaver on 14th June, 2019 ( 31st Jestha, 2076) to gain more knowledge about silkworm . When we got on the bus it was around 10:20 AM and we reached our destination on 11:58 AM. The place was very beautiful and peaceful the compound was also really big with many mulberry leaves where there is sufficient area for doing seri-culture. We were only shown the farming of seri-silkworm which is feed on mulberry leaves.There we saw the silk of silkworm, materials and machine required for the processing of thread. After visiting the field we were given more knowledge about silkworm.

According to my understanding, There are two types of silkworm cultivated in Nepal i.e. Seri-silkworm and Eri-silkworm. Seri-culture is the process of rearing silkworm on commercial scale. The small invertebrates insects which are feed on mulberry leaves are known as silkworm. It was found that silkworm are easily cultivated. The teacher(the person who was guiding and giving us knowledge about silkworm) showed us complete metamorphosis in their life cycle. There are 4 stages of silk worm i.e. egg, larva, pupa and adult. In larva there is again a stage which consists of 5 stage that are:-
1) 1st instar
After incubating eggs for about two weeks 1st instar are hatched and they are feed for about 6 days and are stopped feeding for 24 hours and are moult into 2nd instar.
2) 2nd instar
After feeding for 12 days they are stopped feeding for 24 hours and are moult into 3rd instar.
3) 3rd instar
After feeding for about 18 days they are stopped feeding for 24 hours and moults into 4th instar.
4) 4th instar
After feeding for 24 days they are stopped feeding for 24 hours and moults into 5th instar.
5) 5th instar
It is the final stage of larva. It consists of well-developed silk gland and 5th instar starts to produce silk thread and wrap itself in to cocoon.
Lastly, Seri-culture is beneficial for the economic purpose in the context of Nepal. Getting all this information about silkworm wouldn't have been possible if our teachers haven't gave this chance. For providing this kind of facilities and practical education for all the students we are very thankful to the school administration for this opportunity.
THANK YOU!!!!
