Toxicity of 15 insecticides to brontispa longissima gestro and asecodes hispinarum bou ek , a parasitoid of b . longissima 15种杀虫剂对椰心叶甲幼虫及椰甲截脉姬小蜂的毒性
Influence of developmental stage of host plant leaves on the larval development and survival of brontispa longissima gestro 寄主植物叶片生长阶段对椰心叶甲幼虫生长发育的影响
The feasibility of the controlling coconut leaf beetle brontispa longissima with introducing natural enemies asecodes hispinarum 引进天敌椰甲截脉姬小蜂防治椰心叶甲的可行性探讨
The outdoor parasitical efficiency of t . brontispae was normally 40 % - 50 % and tiptop was 100 % , a . hispinarum was normally 20 % - 30 % and tiptop was 47 % 椰心叶甲啮小蜂的大田寄生率一般为40 % ~ 50 % ，最高可达100 % 。
Culture of brontispa longissima ( gestro ) and its two parasitical natural enemies , tetrastichus brontispae fer . and asecodes hispinarum have been developed in research 摘要开展对椰心叶甲的饲养及其两种寄生性天敌椰心叶甲啮小蜂和椰甲截脉姬小蜂的培育繁殖研究。
The culture technology developed increasingly , and day output increased by three and four times for t . brontispae and a . hispinarum moreover , the parasites were fine in quality and efficiency , which insured the controlled effect when released outside 饲养培育从原来采用的“两室繁蜂法”改进为现在的“五室繁蜂法” ，椰心叶甲啮小蜂和椰甲截脉姬小蜂的日产量分别是原来的3倍和4倍，而且蜂种质量优良、寄生率高，能保证大田释放控制效果。
