Abstract

The mating age for successful production of viable eggs of Asian corn borer (ACB), Ostrinia furnacalis (Guenne), was determined using the arranged pairing test whereby day-, 2d-, 3d-, 4d-, and 5d-old males were paired with day-, 2d-, 3d-, 4d-, and 5d-old females by age group, replicated at least 30 times for a total of 1,654 ACB pairs. Results showed that females at all the ages tested laid eggs. Means of eggmasses laid were higher in younger females regardless of age of males. Conversely, old females mated by old males (5d-old male: 5d-old female) laid fewer eggs. Generally, when males of all ages were paired with younger females, the latter laid eggs comparable to those of females in younger pairs. However, hatchability of eggs was higher for those laid by younger pair combination and lowest for 5d-old male: 5d-old female pairs.
