The Role of Insects Controlling Pests and Trichogramma SPP Potential

Pest control is an essential aspect in agriculture to maintain the productivity and quality of the yield. One environmentally friendly control method is the use of natural enemies, one of which is Trichogramma spp. Trichogramma spp is an effective pest insect egg parasitoid in suppressing pest populations. The use of Trichogramma spp as a biological control agent has been widely recognized due to its ability to target specific pest species, reducing the need for chemical pesticides and minimizing the risk of environmental contamination.

Research conducted by Maman K S Silaban in 2017 aims to determine the effectiveness of the propagation Trichogramma spp in the laboratory by paying attention to the ratio of the number of host eggs (pest insect eggs) and the duration of irradiation. This research was conducted at the Research and Development Center for PTPN II Sei Semayang sugar cane plantation, Medan, during April to May 2017. The study's objective is to provide valuable insights into the optimal conditions for Trichogramma spp propagation, which can be applied in integrated pest management (IPM) programs.

Research Methods and Results Obtained

This study uses a factorial complete random design method with two factors. The first factor is the ratio of the number of host pias, namely 1 (starter piece): 6 (host piece), 1 (starter piece): 8 (host piece), and 1 (starter piece): 9 (host piece). The second factor is the length of irradiation, which is 15 minutes, 25 minutes, and 35 minutes. The combination of these two factors produced 36 treatments with 3 replications. The experimental design allows for the evaluation of the interaction between the two factors, providing a comprehensive understanding of the effects of the ratio of host pias and the length of irradiation on Trichogramma spp propagation.

The results showed that the treatment with 1 (starter piece): 9 (host piece) and the length of irradiation 35 minutes (T2) produced the highest percentage of parasites. This shows that the more the number of host pias available, the more eggs Trichogramma spp can be parasated. In addition, the length of irradiation also has a significant influence on the development of Trichogramma spp. The optimal length of irradiation for Trichogramma spp propagation is 35 minutes, which is essential for the development of the parasitoid.

Further Analysis

This study provides an important picture of how to optimize the propagation of Trichogramma spp in the laboratory. The comparison factor of the number of host pias and the length of irradiation plays an important role in determining the success of the propagation. The results of this study can be applied in the Integrated Pest Control Program (PHT) using Trichogramma spp. By understanding the factors that affect the propagation of Trichogramma spp, it is expected to increase the population and effectiveness of this parasitoid in suppressing the pest population and increasing crop yields.

Recommendations and Conclusions

This study suggested that further research be carried out to examine other factors that can affect the propagation of Trichogramma spp, such as the type of host, temperature, and humidity. By understanding these factors, it is expected to increase the efficiency and effectiveness of propagation Trichogramma spp in the laboratory. The results of this study can be used as a reference for future research on Trichogramma spp propagation and its application in IPM programs.

Conclusion:

This study succeeded in showing that the comparison of the number of host pias and the length of irradiation had a significant influence on the propagation of Trichogramma spp in the laboratory. The best treatment is to use 1 (Starter Piece): 9 (Host Piece) and 35 minutes of irradiation. The results of this study can be applied in an integrated pest control program to increase the effectiveness of Trichogramma spp in suppressing pest populations.

Implications and Future Directions

The findings of this study have significant implications for the development of IPM programs using Trichogramma spp. The optimal conditions for Trichogramma spp propagation, as determined in this study, can be applied in various agricultural settings to increase the effectiveness of this parasitoid in suppressing pest populations. Furthermore, the study's results can be used as a reference for future research on Trichogramma spp propagation and its application in IPM programs.

Limitations and Future Research Directions

This study has several limitations that need to be addressed in future research. Firstly, the study only examined the effects of the ratio of host pias and the length of irradiation on Trichogramma spp propagation. Future studies should investigate the effects of other factors, such as the type of host, temperature, and humidity, on Trichogramma spp propagation. Secondly, the study only used a single type of host, which may not be representative of all host species. Future studies should investigate the effects of different host species on Trichogramma spp propagation.

Conclusion and Recommendations

In conclusion, this study provides valuable insights into the optimal conditions for Trichogramma spp propagation in the laboratory. The results of this study can be applied in IPM programs to increase the effectiveness of Trichogramma spp in suppressing pest populations. However, further research is needed to examine the effects of other factors on Trichogramma spp propagation and to develop more effective IPM programs using this parasitoid.
