| Abstract: | Rodolia limbata occurs one generation a year in Xi ,an, Shaanxi, is lives through winter and summer by means of imago. The imago of overwinter start action, fetch and copulation from the end period of Feb. to the early period of Mar. The period of nit is from the middle period of Mar. to the early period of May, larva is from the early period of Apr.to the early June, pupae is from the early May to the early June, imago is from the middle May to the middle May of mext year. It can effective cortrol the harm of Drosicha corpulena To breed Rodolia limbata im forestry and hang im the harmful area. |
