The seabuckthorn carpenter moth, Holcocerus hippophaecolus Hua, Chou, Fang et Chen is recently a major pest of seabuckthorn in Inner Mongolia Autonomous region, Liaoning, Shanxi, Ningxia and Shaanxi provinces in China. The generation time of H. hippophaecolus is four years. The larvae cause damage primarily to the stems and roots of seabuckthorn, and the mature larvae pupate in soil.

Four sorts of sex pheromones that were mixed at different ratios with three kinds of main sex pheromone components of seabuckthorn carpenter moth:-7-tetradecenyl acetate (Z7-14:Ac),-3-tetradecenyl acetate (E3-14:Ac) and-7-tetradecenyl acetate (E7-14:Ac), were experimented in the field. The results showed that four kinds of pheromones all had strong, attractive effects on male moths.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
