ABSTRACT ABSTRACTABSTRACT ABSTRACT
Maize (Zea mays L.) is one of the main agricultural commodities contributing to national food security and has strategic value because it can be cultivated in various regions. However, maize production in Riau Province has decreased due to infestations by the corn ear borer (Helicoverpa armigera Hubner), which may cause yield losses of up to 40%. Farmers generally use synthetic insecticides to control this pest, but excessive application negatively affects ecosystems, leading to resistance, resurgence, secondary pest outbreaks, and the death of non-target organisms. Utilizing natural enemies offers an alternative approach. The earwig (Euborellia annulata Fabricius) is a natural predator of various maize pests. This study aimed to determine its predation ability against H. armigera larvae under laboratory conditions. The experiment used a Completely Randomized Design (CRD) with five treatments and four replications, producing 20 experimental units. Treatments consisted of one female, one male, two females, two males, and a male–female pair of E. annulata, each provided with 25 second-instar H. armigera larvae. Observed parameters were the number of larvae consumed per hour, predation rate, total larvae consumed, and predation behavior. Data were analyzed using ANOVA followed by DNMRT at a 5% significance level. Results showed that two female E. annulata had the highest predation rate (84%) with 21 larvae consumed within 21 hours, indicating strong potential as a biological control agent for H. armigera in maize fields.
Keywords: Biological control, prey ability, predator, male, female
