Using Luseweilei insecticide to control Dendrolimus superans T.

Luseweilei is an easily-bursted microcapsule insecticide. A test of effectiveness of the insecticide to control the larvae of Dendrolimus superans T. was carried out in larch forest in Baoan Forest Farm of Nehe City, Heilongjiang Province, in April 2001. The solutions of different concentrations (1:150, 1:250, 1:350, and 1:450 Luseweilei : water) were sprayed on the larch trunk before the overwintering larvae climbing on trees and the spraying lengths (height) designed were 1.0, 2.5, and 3.5 m high from ground. The control result showed that spraying 150-, 250-, and 350-fold solutions of the insecticide all produced a good control result, with a mortality rate of 97%, but the 450-fold solution only produced 70% mortality. It is concluded that this insecticide can be used as a kind of good insecticide to control the overwintering larvae of D. superans in spring. Spraying 350-fold solution of easy-burst microcapsule insecticide and one meter spraying length are recommended for the future application..

我不是一个怪人

人们总把我看成是一个不可理喻的怪人。我要申明的是,我不是什么怪人,尤其不是应从社会中清除的野蛮的粗鲁的人。的确,我常常衣冠不整,样子很寒酸,不能保持很庄重的样子。因为我长期都没有收入,我的衣服都是我弟弟提奥的旧东西改的,有些还是廉价的布料做的,加上在作画时再溅上些颜料,我无法成为一个受欢迎的人。

永远辉煌的青春

引子有名的英雄是令人尊敬的,无名的英雄更是可贵的;活着的英雄是令人敬佩的,逝去的英雄却更使后人敬仰。作为国家和民族的脊梁,共和国的旗帜上印有他们血染的风采;中国人民解放军的钢铁洪流中,有他们正气的雄风……我们怀念他们,也想念他们,他们如一支支精神火炬。

喷气飞人

蔚蓝的天空下,忽然出现了一个小黑点,小黑点越来越清晰,它竟然是一位长着翅膀的飞人!这位飞人继续向前飞去,把身下的崇山峻岭都远远的抛在了后面……飞天梦想“我要是能在天空飞翔就好了!”瑞士人罗西望着天空感慨。
