摘  要:
波纹杂毛虫(Cyclophragma undans)在闽北地区1 a发生2代,以3~4龄的幼虫在树干基部杂草中、枯枝落叶层下越冬,翌年3月下旬至4月上旬越冬幼虫开始出蛰活动取食。幼虫老熟后,下树到地面的枯枝落叶层下、杂草丛中以及土缝中结茧化蛹。雌雄成虫一生仅交尾一次。成虫具有强趋光性,卵主要是产于马尾松的中、下部二年生枝条松针上,卵呈卵块或念珠状,少数散生。第二代幼虫于7月上旬开始危害。波纹杂毛虫多发生在海拔300~500 m丘陵地的向阳山坡、立地条件较差的林地。

摘  要:
Cyclophragma undans(Walker) had 2 generations per year in northern Fujian,and overwinter as 3-4instar larvae in the trunk base department weeds,and the withered fallen leaves layer.The overwinter larvae began active and feed from the last ten days of March to the first ten days of April in the next year.The adult larvae climb down to the trunk base department weeds,the withered fallen leaves layer and the gap of soild for oval papal.The adult only mate once one life,had axis of light,laid the eggs in the leaf of two-years Pinus massoniana.The ovum presented the ovum lump or bead form,minorities were scattered.The second generation of larva began to feed in the first ten days of July.Cyclophragma undans occurred in 300~500 m above sea level on south facing slop of hilly forests with poor site condition hill.
