Study on Caragfana Seed Development Stages And The Population Dynamics of Pests

doi:10.7668/hbnxb.2007.S3.014

Abstract

Abstract: Seed pests have caused heavy losses to Caragana seed industry. In order to bring the Caraganaseed pest under control, the paper conducts a study on the inherent relation between the Population dynamicsand Ccaragana seed development stages. The main result found in the study include: (1) Caragana seeddevelopment was seriously effected by pests. (2)The loss of weight due to pests is 3.128 in per 1000 seeds, and Invaded seed weight account for 13.23%. (3)Three kinds of pests grow rapidly to mature by closely combining with Caragana's limited growth and development stages, and damaging Caragana seed.

Key words: Caragana, Seed development, Population dynamics
