The Effect of Jeringau Rhizome Extract (Acorus calamus L) on Spodoptera Litura F (Lepidoptera; Noctuidae) in Cabbage in the Laboratory

Introduction

In Indonesia, the demand for vegetables continues to increase, with around 70% of the population living in rural areas and the remaining 30% in urban areas. Cabbage is one of the most consumed vegetables, rich in vitamin A and other essential nutrients. However, its growth is threatened by pests, including Spodoptera Litura, a polyphag leaf-eating insect that can cause significant damage to various crops, including cabbage. In this study, we aim to investigate the effect of Jeringau rhizome extract (Acorus calamus L) on Spodoptera Litura F (Lepidoptera; Noctuidae) in cabbage in the laboratory.

Background

Cabbage is a nutrient-rich vegetable that contains various essential vitamins and minerals, including vitamin A, calcium, potassium, phosphorus, and iron. In 100 grams of raw cabbage, there are 24 calories and other important nutrients that are beneficial for health. However, cabbage growth is often threatened by pests, including Spodoptera Litura, which is a polyphag leaf-eating insect that can cause significant damage to various crops, including cabbage.

Spodoptera Litura is a member of the Order of Lepidoptera and the Family of Noctuidae, which is one of the biggest insect families. This pest is known to attack various types of plants, including soybeans, tobacco, peanuts, potatoes, chili, onion, and cabbage. In Indonesia, these pests often cause significant damage to crops, with the damage caused by Spodoptera Litura reaching up to 80% if not controlled. The pest can attack in the vegetative, generative, or both stages of plant growth.

The Need for Effective Pest Control

With the increase in damage caused by Spodoptera Litura, it is essential to find effective solutions in pest control. One interesting alternative is the use of Jeringau rhizome extract (Acorus calamus L) as a biocontrol agent. This plant has been known in traditional medicine and has the potential to have active compounds that can interfere with the development and survival of Spodoptera Litura larvae.

The Potential of Jeringau Rhizome Extract

Jeringau rhizome extract (Acorus calamus L) has been known in traditional medicine for its various health benefits. The plant has been used to treat various ailments, including fever, rheumatism, and digestive problems. The extract has also been shown to have antimicrobial and antifungal properties, making it a potential candidate for use as a biocontrol agent.

Methodology

In this study, testing will be carried out in the laboratory to determine the effect of the Jeringau rhizome extract on the Larva Spodoptera Litura which attacks the cabbage. The methods used include larvae sampling, jeringau extract treatment, and observation of the mortality rate and larvae development after treatment. The results of this study are expected to provide a clear picture of the effectiveness of Jeringau extract as a pest control agent.

Expected Outcomes

The results of this study are expected to provide a clear picture of the effectiveness of Jeringau extract as a pest control agent. The study aims to investigate the effect of Jeringau rhizome extract on Spodoptera Litura F (Lepidoptera; Noctuidae) in cabbage in the laboratory. The expected outcomes of this study include:

The effect of Jeringau rhizome extract on the mortality rate of Spodoptera Litura larvae
The effect of Jeringau rhizome extract on the development of Spodoptera Litura larvae
The potential of Jeringau rhizome extract as a biocontrol agent for Spodoptera Litura

Conclusion

In conclusion, this study aims to investigate the effect of Jeringau rhizome extract on Spodoptera Litura F (Lepidoptera; Noctuidae) in cabbage in the laboratory. The study uses a combination of larvae sampling, jeringau extract treatment, and observation of the mortality rate and larvae development after treatment. The expected outcomes of this study include the effect of Jeringau rhizome extract on the mortality rate and development of Spodoptera Litura larvae, as well as the potential of Jeringau rhizome extract as a biocontrol agent for Spodoptera Litura.

Recommendations

Based on the expected outcomes of this study, the following recommendations can be made:

Further research is needed to confirm the effectiveness of Jeringau rhizome extract as a biocontrol agent for Spodoptera Litura
The use of Jeringau rhizome extract as a biocontrol agent for Spodoptera Litura should be further explored in field trials
The potential of Jeringau rhizome extract as a biocontrol agent for other pests should be investigated

Future Directions

This study provides a starting point for further research on the potential of Jeringau rhizome extract as a biocontrol agent for Spodoptera Litura. Future studies should aim to confirm the effectiveness of Jeringau rhizome extract as a biocontrol agent and explore its potential as a biocontrol agent for other pests. Additionally, further research is needed to understand the mechanisms by which Jeringau rhizome extract affects the development and survival of Spodoptera Litura larvae.
