Statement 1: Exactly one of the integers is negative.
As the odd integers are consecutive, the smaller one must be negative and the other one must be positive. Only such possible pair is -1 and 1. And their product is -1.
Sufficient.
Statement 2: At least one of the integers is positive.
Both of them may be positive or one of them may be positive.
Not sufficient.
