Spatial Distribution Patterns and Sampling Techniques of a New Pest Bembecia kaszabi in Licorice Roots
摘要
Abstract
In order to clarify the infestation and spatial distribution pattern of Bembecia kaszabi larvae in licorice roots and the theoretical sampling technique,provide technical support for the scientific population survey and control of the pest.,in this study,the spatial distribution pattern of the Bembecia kaszabi larvae in licorice roots was investigated by using six aggregation indices(C,Ca,I,m*,m*/m,and k),the Iwao regression analysis method,and Taylor's power law,and the theoretical and sequential sampling techniques of Iwao were applied to calculate the Blackith's aggregation mean value λ,the reasons for the aggregation of the Bembecia kaszabi larvae were analyzed,and a theoretical sampling number and sequential sampling model for the field survey of the Bembecia kaszabi larvae in the roots of licorice was established.The results showed that the infestation rate of the Bembecia kaszabi larvae on different annual licorice ranged from 4.83%to 43.00%,and the average population density ranged from 0.02 to 1.75 head/plant.The spatial distribution pattern of the Bembecia kaszabi larvae in the licorice field was generally aggregated,and the basic components of the distribution were groups of individuals,which were attracted to each other,and were greatly affected by the population density,and the degree of aggregation gradually increased with the increase of the population density,and the reason for the aggregation was a result of the joint action of the environmental conditions and the inherent characteristics of the larvae.The theoretical sampling model and the sequential sampling technique based on the control index for the Bembecia kaszabi larvae under different population densities were further analyzed and proposed.关键词
