- Abstract
Oryzophagus oryzae mating behavior and mate recognition were investigated. Bioassays revealed that couples had intense sexual activity in the first 3 h of photophase and scotophase. Adults mated and re-mated at any time of day in the presence of water; however, in the absence of water, only 10 % of adults mated, meaning that water was important for couples to find each other. In the sequence of pre-mating behaviors bioassay four steps were observed and females were always attracted to males, seeking them, before copulation; after mating, males showed guarding activity of variable duration, allowing remating. Cuticule extractions revealed that both sexes had similar cuticular chemical compounds. They were identified as aldehydes and a ketone, probably because of its aquatic life habits. Bioassays suggested that males recognized females by their cuticle composition.
