An investigation into the use of multiple site characteristics to predict the presence and infestation level of wireworms (Agriotes spp., Coleoptera: Elateridae) in individual grass fields

摘要: Summary Sixty-two grass fields were sampled in England and Wales over a three year period to assess the level of wireworm population present. Data on site-specific variables including soil physical characteristics, duration, genera diversity other abiotic factors such as field aspect, altitude, meteorological parameters collected at each site. Only duration bulk density showed any association with infestation stauts when considered single variates. from sub-set 41 used develop series multi-variate discriminant rules predit presence/absece individual fields. These vaildated using data remaining 21 In general, tended over-estimate number wireworm-infested by misclassifying uninfested infestes. Multivariate models predict populaiton levels infested also developed multiple generalised linear regression. The predictive accuracy these was poor. Neither prediciton nor presence/absence rulses accounted fully for large inte-field variation status.
