Abstract
A method of collecting the eggs of Micromus tasmaniae, an insect predator of the potato aphid
attacking the potato plant is described. The method was adopted for use in the mass production of
the eggs needed for field release trials. Prior tests conducted in the laboratory showed that a solution
of sodium hypochlorite (NaC10) at either 0.75% or 1.00% concentration did not have detrimental
effects on egg hatch after immersing th.em jor 6 or 10 minutes, respect~·vely. Seventy five percent
(75%) of the eggs were removed from the cloth substrate and 95% of them hatched, Sodium hypochloride
at 5% concentration caused the failure of all the eggs to hatch but all of the eggs were
easily removed from the substrate. This method has reduced egg damage and collection time as compared
to the conventional method whereby each egg is collected one by one.
