Preference Test of Several Types of Family Leaves of Euphorbiaceae as Alternative Feeds on the Growth and Development of Silkworms (Samia Cynthia Ricini) (Lepidoptera: Saturniidae)

Introduction

The cultivation of silkworms is an essential industry in many countries, including Indonesia, where the production of silk is a significant contributor to the economy. However, the high cost of feed is a major challenge faced by farmers, which can limit their productivity and profitability. In recent years, there has been a growing interest in exploring alternative feed sources that can increase silkworm productivity while reducing costs. One such alternative feed source is the leaves of the Euphorbiaceae family, which are rich in nutrients and can provide a sustainable solution to the feed problem.

Background

The Euphorbiaceae family is a diverse group of plants that includes over 300 species, many of which are found in tropical regions. The leaves of these plants are rich in nutrients, including proteins, carbohydrates, and fiber, making them an attractive alternative feed source for silkworms. In recent years, there has been a growing interest in exploring the potential of Euphorbiaceae leaves as a feed source for silkworms, with several studies investigating their nutritional value and feeding behavior.

Research Methodology

The study was conducted by Puja Anggita Panjaitan in 2020 at the Plant Pest Laboratory of the Faculty of Agriculture, University of North Sumatra. The study aimed to investigate the preference of silkworms (Samia Cynthia Ricini) for different types of Euphorbiaceae leaves as an alternative feed source. The study used a total of 10 different types of Euphorbiaceae leaves, including Manihot esculenta (cassava), Melia azedarach (cassia), and Aleurites moluccanus (tung oil tree).

Results

The results of the study showed that the leaves of Manihot esculenta (cassava) were the most preferred feed source by silkworms. The study found that the leaves of M. esculenta significantly increased the growth of silkworms, including daily weight gain, feed conversion efficiency, and larval weight. The study also found that the leaves of M. esculenta contributed to an increase in the weight of the pupa, the weight of the silk gland, the weight of the cocoon skin, and the length of the silk yarn produced.

Discussion

The results of the study highlight the importance of exploring alternative feed sources that can increase silkworm productivity while reducing costs. The selection of leaves from the Euphorbiaceae family, such as M. esculenta, not only benefits the growth of silkworms but can also have a positive impact on the economy of silkworm cultivation. With the presence of more efficient and economical feed, farmers can increase their crops without having to depend on more expensive or difficult to obtain feed.

In addition, this finding also provides insight into the behavior of eating polyfagus silkworms. This knowledge is very valuable for the development of a more sustainable cultivation strategy, where the use of local plants can be maximized. By increasing feed efficiency, farmers not only reduce operational costs but also support environmental sustainability by using the resources that are around them.

Conclusion

In conclusion, the results of Puja Anggita Panjaitan's research highlighted the importance of alternative feed exploration in supporting the growth of silkworms. This finding provides a great opportunity for innovation in silk cultivation, which is not only beneficial for farmers but also for the textile industry that depends on the quality and quantity of silk products produced.

Recommendations

Based on the results of the study, the following recommendations are made:

Further research: Further research is needed to investigate the nutritional value and feeding behavior of silkworms on different types of Euphorbiaceae leaves.
Commercialization: The results of the study suggest that the leaves of M. esculenta can be used as a commercial feed source for silkworms. Further research is needed to develop a commercial feed product that can be used by farmers.
Sustainable cultivation: The study highlights the importance of sustainable cultivation practices, where the use of local plants can be maximized. Farmers should be encouraged to use local plants as feed sources for silkworms.

Limitations

The study has several limitations, including:

Small sample size: The study used a small sample size of 10 different types of Euphorbiaceae leaves.
Limited geographic scope: The study was conducted in a single location, the Plant Pest Laboratory of the Faculty of Agriculture, University of North Sumatra.
Limited duration: The study was conducted over a short period of time, from June to August 2020.

Future Directions

The study provides a foundation for further research on the use of Euphorbiaceae leaves as a feed source for silkworms. Future studies should aim to:

Investigate the nutritional value: Investigate the nutritional value of different types of Euphorbiaceae leaves as a feed source for silkworms.
Develop a commercial feed product: Develop a commercial feed product that can be used by farmers.
Explore the use of local plants: Explore the use of local plants as feed sources for silkworms.
