Abstract

In the mass production of M. ancylivorus, clorox is used to eliminate the cocoons of the potato tuber worms. The parasitic cocoons may then be separated from the naked pupae of the tuber worm by passing the mixed population into 95% alcohol. The tuber worm pupae sink and the parasite cocoons float and may be skimmed off in 30 sec.
