Rangrang Oecophylla Smaradigna (Hymenoptera: Formicidae) Ant Preference Tests on Snail Pests Do Not Scatter (Parmarion Pupillary (Humb.))

Introduction

In the world of agriculture, pests are one of the biggest challenges that farmers must face. One of the main pests that attack oil palm plants is the spodoptera litura, or better known as grayak caterpillars. In addition, snails not scattered Parmarion Pupillaris are also considered as pests that can reduce oil palm production. To overcome this problem, Oecophylla Smaradigna, which is a generalist predator, can act as one of the solutions in controlling these pests. This study aims to observe this predatory behavior and measure the ability to predict the larvae of the two pests.

The Importance of Oecophylla Smaradigna in Pest Control

Oecophylla Smaradigna, also known as the rangrang ant, is a species of ant that is widely distributed in Southeast Asia. These ants are known for their ability to farm leaves and build complex nests. However, they are also generalist predators that feed on a wide range of insects, including pests that attack oil palm plants. In this study, we aim to investigate the predatory behavior of Oecophylla Smaradigna and its ability to control the populations of grayak caterpillars and snails not scattered.

Research Methods

The study was conducted in the Asian Agri Group garden in the Old State Garden of the Central State in September to December 2017. The research design used was a complete random design of 2 factors. The first factor is a type of predator, namely workers and soldiers. While the second factor is related to instar larvae, namely the 2nd and 4th larvae of the two types of pests. Each treatment is repeated three times to get more accurate results.

Results and Discussion

The results showed that the Predator Oecophylla Smaradigna had a significant influence on the mortality of S. Litura larvae. The highest percentage of mortality occurs in the 2nd instar larvae which reaches 50.00%. This shows that the young larvae of S. Litura are more vulnerable to predatory attacks than the 4th instar larvae which only reach mortality of 30.00%. Both are significantly different from other treatment.

The time spent by predators in finding an average prey was 9.30 minutes. The speed of handling prey is very important, because it shows the efficiency of predators in controlling pest populations. The 2nd S. Litura instar larvae are reported to be paralyzed faster by O. smaradigna compared to older instar larvae.

Preference testing conducted by the Y-Maze Bioassays method also revealed that O. Smaradigna prefers to prey on S. Litura rather than P. Pupillary. This shows that predation by rangrang ants can focus on pests that are more dangerous for oil palm.

The Role of Oecophylla Smaradigna in Biocontrol

From this study, it can be concluded that Oecophylla Smaradigna is an effective predator of S. Litura larvae and has a higher preference to prey on grayk caterpillars compared to snails not scattered. Thus, the application of rangrang ants as biocontrol agents in oil palm plants is highly recommended to control pest populations. These results provide useful insights for farmers and researchers in an effort to maintain the health of oil palm plants and increase overall production.

Conclusion

In conclusion, this study has shown that Oecophylla Smaradigna is a highly effective predator of S. Litura larvae and has a higher preference to prey on grayk caterpillars compared to snails not scattered. The application of rangrang ants as biocontrol agents in oil palm plants is highly recommended to control pest populations. These results provide useful insights for farmers and researchers in an effort to maintain the health of oil palm plants and increase overall production.

Recommendations

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

  • The use of Oecophylla Smaradigna as a biocontrol agent in oil palm plants is highly recommended to control pest populations.
  • Further research is needed to investigate the effectiveness of Oecophylla Smaradigna in controlling other types of pests that attack oil palm plants.
  • The use of Y-Maze Bioassays method is recommended for preference testing of predators and prey.

Limitations of the Study

This study has several limitations that need to be addressed in future research. These include:

  • The study was conducted in a controlled environment, and the results may not be applicable to field conditions.
  • The study only investigated the predatory behavior of Oecophylla Smaradigna against two types of pests, and further research is needed to investigate its effectiveness against other types of pests.

Future Research Directions

Future research directions include:

  • Investigating the effectiveness of Oecophylla Smaradigna in controlling other types of pests that attack oil palm plants.
  • Investigating the use of Oecophylla Smaradigna as a biocontrol agent in other types of crops.
  • Investigating the use of Y-Maze Bioassays method for preference testing of predators and prey.
