Evaluasi pelepasan Trichogramma spp. untuk pengendalian penggerek pucuk dan batang tebu

Biological control research in Indonesia has a long history since it was started by Dutch scientists more than 100 years ago. Currently, the number of research has arisen, but there has been no systematic analysis of how this research produces technology that can be practiced in the field. This analysis is essential since it provides baseline information about biocontrol research and provides future research direction. This study aims to conduct a systematic review of biocontrol research conducted in Indonesia over the past 20 years. All articles were obtained from various databases using keywords related to biocontrol. A total of 437 articles were analyzed. We focussed our research on predators and parasitoids and found 269 articles related to parasitoids and predators. We found that biocontrol research in Indonesia was dominated by research on insect pathogens. Further analyses showed that research on identification and biology dominated most of the studies on predators and parasitoids. Almost all the research that was conducted addressed the basic biology of different types of natural enemies for different crops’ pests but has not addressed the full-scale host-parasitoid research that is needed to develop natural enemies that are ready to be released on a large scale. Four natural enemies have been reported in large-scale applications: Anagyrus lopezi, Lanius schach, Trichogramma spp., and Tetrastichus brontispae. There is limited research on the mass release of parasitoids or predators in the field. Most of the research on releases was focussed on the short-term establishment without long-term evaluation and measure of success. It leads to a knowledge gap in biological control research and should become one of the future research directions.

The sugarcane shoot borer (Scirpophaga excerptalis) is an herbivorous insect that primarily infests sugarcane plants, leading to the development of dead heart symptoms. This study aimed to investigate the contribution of egg parasitoids in mitigating the occurrence of dead heart caused by S. excerptalis infestation. The research was conducted in Asembagus and Malang, East Java, Indonesia. The samples collection of shoot borer eggs were done twice in Asembagus, and three times in Malang. The collected eggs were examined to determine the percentage of parasitism, and the emerged parasitoids were identified. The infestation level of shoot borers was evaluated by counting the dead heart symptoms within 5 m2 observation units, comprising 18 and 15 units in Asembagus and Karangploso, respectively. Three species of parasitoids, namely Telenomus sp., Trichogramma chilonis, and Tetrastichus sp., were found to parasitize S. excerptalis eggs. The average parasitism levels by Telenomus sp., T. chilonis, and Tetrastichus sp. were 74% (ranged: 50-100%), 0.6% (ranged: 0-4.4%), and 14.3% (ranged: 0-100%), respectively. Telenomus sp. was the predominant egg parasitoid observed in all observations at both sites. There was an inverse relationship between the mortality of shoot borer eggs by parasitoids and the occurrence of dead heart symptoms. Higher levels of parasitism were associated with reduced dead shoot symptoms. The natural control of S. excerptalis through the complex of egg parasitoids holds a promise for effective management of sugarcane shoot borers and promoting sustainable agriculture.

Sugarcane-borers complex in Indonesia consists of a shoot borer (Scirpophaga excerptalis) and four stem borers (Chilo sacchariphagus, C. auricilius, Sesamia inferens and Tetramoera schistaceana). Control of these borers is carried out biologically through the release of egg parasitoid Trichogramma spp. There are four species of mass-produced egg parasitoids and are used in the borer control program, namely Trichogramma japonicum, T. chilonis, T. nanum, and T. minutum. During this time, to measure the level of effectiveness of egg parasitoid releases was through the level of stalk damage. The effectiveness of the release of egg parasitoid should be measured through the mortality rate of borer eggs or parasitization level by the parasitoid. The observations in sugar cane plantations with release and without release of the Trichogramma spp. showed that releases of T. japonicum and T. chilonis were not effective in causing borer egg mortality. The level of parasitization of the borers’ eggs in both plantations was not significantly different, and the parasitization of sugarcane borer eggs was observed mostly due to natural egg parasitoid species, such as Tetrastichus sp., Telenomus sp., and T. chilonis. Biological control of the sugarcane borer complex by mass release of egg parasitoid needs to be reviewed.
