Lepidoptera captured on the East China Sea in 2005 and predicted migration sources

This paper provides a list of moths captured in a region at latitudes 29–32°N and longitudes 127–130°E on the East China Sea on 14–28 June and 1–7 July 2005. Sixteen species of moths from the families Plutellidae, Crambidae, Sphingidae and Noctuidae were identified. Among these, three species were recorded on the East China Sea for the first time. The migration paths of the captured moths were analyzed using a three‐dimensional backward trajectory analysis method. Predicted migration sources for these moths are Taiwan and Fujian, Guangdong, Jiangxi, Zhejiang, Jiangsu, and Anhui provinces in China.     

Control of self-incompatibility by CO2 gas in Brassica

Pollen tubes penetrated stigma papilla cells in flowers thatwere illegitimately (self) pollinated, after CO₂ treatment ofthese flowers. This shows that the self-incompatible reactionin Brassica can be removed by CO₂ gas. Ethylene gas was noteffective. (Received May 16, 1969; )
