In
trials 1 and 2, the screened cages were constructed of
standard window screen (2 mm) and were not ant
proof, resulting in high larval predation. Cages void of
larvae or containing visible larval remains suggestive
of predation were identified as victims of ant predation.
In trial 3, a similar cage made from an in-line liquid
filter (7 3 3 cm diameter) with stainless steel screen
(mesh size-225) was used to eliminate ant effects.
