Exploration of Parasitoid Egg Spodoptera frugiperda on Various Varieties of Corn Plants in Sumber Melati Diski Village, Serdang Regency

Introduction

The control of pests is a crucial aspect of agriculture, and one of the most significant pests that affect corn plants is the Spodoptera frugiperda. This pest can cause significant damage to corn crops, resulting in reduced yields and economic losses for farmers. In recent years, there has been a growing interest in using natural enemies, such as egg parasitoids, to control pest populations. This study aims to explore the effectiveness of egg parasitoids in controlling Spodoptera frugiperda pests on various varieties of corn plants in Sumber Melati Diski Village, Serdang Regency.

Background

Spodoptera frugiperda is a significant pest that affects corn crops worldwide. It is a noctuid moth that feeds on corn leaves and can cause significant damage to the plant. The use of chemical pesticides to control this pest has been the primary method of control, but it has several drawbacks, including environmental pollution and the development of pesticide-resistant pests. In recent years, there has been a growing interest in using natural enemies, such as egg parasitoids, to control pest populations.

Egg parasitoids are a type of wasp that lays its eggs inside the eggs of other insects, including pests. They are a natural and environmentally friendly way to control pest populations. The use of egg parasitoids has several advantages, including reduced environmental pollution, reduced development of pesticide-resistant pests, and increased biodiversity.

Methodology

This study was conducted in Sumber Melati Diski Village, Serdang Regency, from April to June 2023. The study was guided by Ms. Ameilia Zuliyanti Siregar and was conducted on agricultural land owned by local residents. The study used a factorial random design group (shelf) with two factors analyzed. The first factor was the planting pattern (monoculture and intercropping), while the second factor was a corn variety consisting of BISI 2, Paragon, and Pioneer P35, with each treatment repeated four times.

The study used a total of 16 treatments, with 4 replicates for each treatment. The treatments were arranged in a 2x3 factorial design, with the first factor being the planting pattern and the second factor being the corn variety. The study used a random sampling method to select the treatments.

Results

The results of this study showed that there was a genus of egg parasitoid found, namely Telenomus. The highest level of parasitism was recorded in the treatment of intercropping planting patterns with BISI-2 varieties, which was 26.18%. Conversely, the lowest level of parasitism occurred in the monoculture planting pattern with Paragon varieties, which only reached 4.04%.

These findings indicate that intercropping planting patterns are more effective in increasing parasitoid populations, which can help in controlling Spodoptera frugiperda pests naturally. The results also show that the selection of corn varieties can affect the effectiveness of parasitoids in suppressing pest attacks.

Discussion

The existence of parasitoids as a natural enemy of pests is a very important strategy in continuing pest control. The use of egg parasitoids such as Telenomus can not only reduce the population of Spodoptera frugiperda pests but also helps maintain the balance of agricultural ecosystems. This study shows that variations in planting patterns and the selection of corn varieties can affect the effectiveness of parasitoids in suppressing pest attacks.

The intercropping planting pattern is proven to be more effective in supporting the existence of parasitoids. This could be caused by the diversity of plants that exist in the intercropping system, thus creating habitats that are more supportive for parasitoids to multiply. In addition, with intercropping planting patterns, the possibility of mutual benefit between plants can also improve the overall health of plants, which can reduce the impact of pest attacks.

The importance of the selection of corn plant varieties also cannot be ignored. Corn varieties such as Bisi-2 that show high parasitism can be an option for farmers to increase yields while reducing dependence on chemical pesticides. In the long run, this does not only have a positive impact on environmental health but also for public health.

Conclusion

This study provides insight into the effectiveness of egg parasitoids in controlling Spodoptera frugiperda pests on various varieties of corn plants in Sumber Melati Diski Village, Serdang Regency. The results show that intercropping planting patterns are more effective in increasing parasitoid populations, which can help in controlling Spodoptera frugiperda pests naturally. The study also highlights the importance of selecting corn plant varieties that show high parasitism.

Recommendations

Based on the results of this study, it is recommended that farmers use intercropping planting patterns and select corn varieties that show high parasitism to increase yields while reducing dependence on chemical pesticides. This study also provides a reference for further research on pest control and the use of parasitoids as an environmentally friendly alternative.

Future Research Directions

This study provides a foundation for further research on pest control and the use of parasitoids as an environmentally friendly alternative. Future research directions include:

  • Investigating the effectiveness of other natural enemies in controlling Spodoptera frugiperda pests.
  • Studying the impact of climate change on the effectiveness of parasitoids in controlling pest populations.
  • Developing integrated pest management strategies that combine the use of parasitoids with other control methods.

Limitations of the Study

This study has several limitations, including:

  • The study was conducted in a single location, and the results may not be generalizable to other locations.
  • The study used a small sample size, and the results may not be representative of the larger population.
  • The study did not investigate the impact of other factors, such as climate change, on the effectiveness of parasitoids in controlling pest populations.

Conclusion

In conclusion, this study provides insight into the effectiveness of egg parasitoids in controlling Spodoptera frugiperda pests on various varieties of corn plants in Sumber Melati Diski Village, Serdang Regency. The results show that intercropping planting patterns are more effective in increasing parasitoid populations, which can help in controlling Spodoptera frugiperda pests naturally. The study also highlights the importance of selecting corn plant varieties that show high parasitism.
