Abstract
The viability of the oothecae (eggs) of Blattella germanica females which were killed by ingesting fenitrothion MC bait and hydramethylnon bait was studied under the high humidity condition (75 % RH). In case of the females treated with fenitrothion MC bait, 17 oothecae out of 25 (68%) and 520 eggs out of 807 (64.4%) were hatched during the period of 4-24 days after treatment. In case of the females treated with hydramethylnon bait, 15 oothecae out of 25 (60%) and 499 eggs out of 842 (59.3%) were hatched during the period of 1-28 days after treatment. In the control group (decapitated females), 21 oothecae out of 25 (84%) and 728 eggs out of 835 (87.2%) were hatched during the period of 1-24 days after decapitation, which was significantly different from those of the eggs of the females treated with both fenitrothion MC bait and hydramethylnon bait (P<0.05). Neither the degree of maturity of oothecae, nor detachment/attachment of oothecae from/to female abdomens were correlated to the hatching (viability) of the oothecae.
