Effects of eucalyptus oil odor treatment provided to adults of Dysdercus koenigii (Fabr.) (Heteroptera: Pyrrhocoridae) on the insect's reproductive and subsequent postembryonic developmental programs

The eggs of Argas (A.) reflexus (Fabricius, 1794) were kept at temperature of 25 degrees C and at relative humidity (RH) of 90% from 1, 5-6, 8-10 and 21-25 day of the embryonic development. The highest percentage of dead embryos (10.9) was observed in experiments, in which the eggs were incubated at...

Summary:The eggs of Argas (A.) reflexus (Fabricius, 1794) were kept at temperature of 25 degrees C and at relative humidity (RH) of 90% from 1, 5-6, 8-10 and 21-25 day of the embryonic development. The highest percentage of dead embryos (10.9) was observed in experiments, in which the eggs were incubated at 90% RH from 1 day of the embryonic development. In these experiments developed only 42.4-42.7% normal larvae. 90% RH influenced the large percentage (30.1-42.8%) of abnormally hatched larvae. Disturbances in eggs hatching of Argas (A.) reflexus occurred irrespective of the duration of the 90% RH exposures during the embryonic development.
