Abstract
The apicular opening of the cavity between lemma and palea of rice florets is the site of nematode (Aphelenchoides besseyi) entry and this occurs only prior to anthesis. Nematodes were found in natural cavities of florets and grains but never within tissues. Reproduction rates were high in florets before anthesis but declined in the 14 days afterwards and reproduction ceased in maturing grains. About 18 days after anthesis 2nd-stage juveniles became dormant while later stages continued development to adults, possibly because of different responses of 2nd stages and post-2nd stages to declining water content in maturing grains.
