Mass Rearing of Predatory Earwigs, Euborellia annulata for the Control of Asian Corn Borer
Eurobellia annulata is a predatory earwig which can be used as biological control for the Asian corn borer (Ostrinia furnacalis Guenee). It released into the field at the rate of 1 per square meter to control the Asian corn borer population. The technology is a way to mass-rear the earwigs using factitious hosts (dog food and corn cob). The earwigs are mass-reared in the laboratory using a 73 x 37 x 28 cm galvanized box containing a 3:1 soil and sand mixture with a height of 7.5 cm. Fifty male and 150 female adults are introduced into the rearing box for reproduction and regularly fed with a 1:1 ratio of ground dog food and corncobs with a moisture content kept at 27-30%. Two thousand earwigs can be produced in a box in one month. The 3rd instar to adult earwigs are collected from the mass-rearing boxes for release into the field.
