“…In Indonesia, S. excerptalis is frequently cited as one of the most signi cant "pests" of sugarcane, capable of causing 50-70% economic damage (Pawirosemadi, 2011). The rate of top borer infestation in Java's sugarcane crops has uctuated between locations and sugarcane varieties during the past two years (Muliasari and Trilaksono, 2021). Except for varieties with a low tolerance level for this insect infestation, the incidence of top borer infestation, as shown by dead heart symptoms, was normally less than 5% .…”

In Indonesian sugarcane plantations, the infestation severity by the sugarcane shoot borer, Scirpophaga excerptalis, depends on the sugarcane variety and the presence of natural enemies. However, evaluating the resistance of sugarcane cultivars to borer infestations typically involves artificial infestations and laboratory assays that do not take into account the role of natural enemies, especially predatory ants, as a significant factor in the borer larvae's mortality. The predatory ants associated with sugarcane plants could prey on the shoot borer neonate larvae before the larvae reach the growth point of the sugarcane and cause damage. The purpose of this study was to examine the effect of predatory ants on the natural infestation of sugarcane top borer across five varieties of sugarcane, thereby filling a void in the current research concerning the screening of shoot-borer resistance. The study was conducted in sugarcane plantation at Asembagus, East Java, Indonesia. The symptoms of shoot borer infestation on leaves and dead hearts, as well as the number of predatory ants on the sample units were recorded. Top borer infestations varied in intensity across all five sugarcane varieties. Predatory ants and the survival rate of S. excerptalis neonate larvae were closely correlated. Among the five sugarcane varieties, BL had the lowest number of predatory ants and was the most favorable environment for top borer neonate larvae. Predatory ants play a significant role in determining the fate of the shoot borer on sugarcane plants and provide insight into a variety's susceptibility.

“…In general, the level of shoot borer infestation, which is indicated by dead heart symptoms, is less than 5%, especially in tolerant sugarcane varieties [7,8]. One of the reasons for the low infestation of S. excerptalis is due to the role of its natural enemies as an efficient biotic mortality factor.…”

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.
