<正>在福建武夷山地区发现桦木属一新种，并命名为武夷桦（BetulawuyiensisXiaoJia-bin）。

According to experiment that 2.5% Lambda-cyhalothrin CS (capsules suspend dose pattern) controls Blattella germanica, with contrast of 2.5% Lambda-cyhalothrin EC (emul-sifiable concentrate dose pattern), the new pesticide dose pattern not only has excellent fast effects for the health pests, but also has a long controlling effect more than 98-days on no-absorbing board for the technical toxicant enwraped. The new health pesticide solves a series of problems that common aerosols have, such as easy explosion, easily burning, with special odd-or, resulting in pollution etc.
