STUDIES ON BESAIA GODDRICA (NOTODONTIDAE,LEPIDOPTERA)

  • Received Date: 1990-05-28
  • Besaia goddrica (Schaus),one of the main pests of the bamboos,attacks the species of Phyllostachys and has been observed in the wide areas on the south of the Yangtze River as well as in Shanxi Province.With four generations per year in Zhejiang province,the pest insect overwinters on bamboos by larvae which may feed on the foliage occasionally at warm noon in winter,but normally eat more in the next March.The adults appear in bamboo groves from early April to early June,early June to mid-July,early August to early September and,mid-September to early November respectively.The larvae feed on the foliage from late April to early July,late June to late August,mid-August to mid-October and,early October to the next early April.The mean feeding amount of the leaves per larva in each one of the four generations is respectively up to 411.85,390.02,335.85 and 324.95cm2 in area.Each female adult may lay eggs varying from 80 to 490.There are more than ten natural enemies attacking the pest,mainly including Trichogramma sp.,Telenomus sp.,Campoplex sp.,Exorista civilis,Sirthenea ilavipes and Enicospilus sp.,The effective control of the pest can be achieved by the measures of tending of bamboo groves,light-trapping,and application of DDVP smoke generator.

Abstract: Besaia goddrica (Schaus),one of the main pests of the bamboos,attacks the species of Phyllostachys and has been observed in the wide areas on the south of the Yangtze River as well as in Shanxi Province.With four generations per year in Zhejiang province,the pest insect overwinters on bamboos by larvae which may feed on the foliage occasionally at warm noon in winter,but normally eat more in the next March.The adults appear in bamboo groves from early April to early June,early June to mid-July,early August to early September and,mid-September to early November respectively.The larvae feed on the foliage from late April to early July,late June to late August,mid-August to mid-October and,early October to the next early April.The mean feeding amount of the leaves per larva in each one of the four generations is respectively up to 411.85,390.02,335.85 and 324.95cm2 in area.Each female adult may lay eggs varying from 80 to 490.There are more than ten natural enemies attacking the pest,mainly including Trichogramma sp.,Telenomus sp.,Campoplex sp.,Exorista civilis,Sirthenea ilavipes and Enicospilus sp.,The effective control of the pest can be achieved by the measures of tending of bamboo groves,light-trapping,and application of DDVP smoke generator.
