  • Received Date: 1993-06-07
  • Micadina yingdeensis Chen et He is a new species of Phasmida which wasfirst discovered in the forest of Yingde County of Guangdong Province where it caused serious damage to Castanopsis fissa Rehd.et Wils.forest. Nymphs and adults fed on leaves of Fagaceae,especially on the leaves of Castanopsis fissa.The damage caused by the adults wasthe most.It has 2~3 generations a year with generation overrapping.The eggs deposited bythe adults of the first and second generations overwintered under the leaf litter.During thelast ten days of the following February,the eggs began hatching.The peak period of the over-wintered adults was from mid-May to late-May.During this period an applications of 3% BHC smoke with a dosage of 15 kg/hm2 could kill this pest and resulted in over 85% mortality.Spraying with Metarhizium anisopliae powder at a dosage of 1.5×1013 spores/hm2 also gave an effective control of 70% mortality.
