【摘要】 为研究广斧螳在土沉香林地对黄野螟的控制效果，在茂名市茂南区公馆镇和电白区观珠镇设置两个试验点，投放人工室内繁殖的2代广斧螳成虫和卵鞘至土沉香林地。通过设置三种处理，调查其对土沉香树的失叶率、虫口密度和螳螂株率的影响。调查结果显示：处理Ⅲ(释放成虫5头·株^-1+释放卵鞘150个·hm^-2)林地失叶率为33%,较CK（65%）下降49.2%,虫口密度为75头·株^-1,较CK(288·株^-1)下降74.0%,使黄野螟有虫不成灾（成灾标准：失叶率>60%）,防控效果良好。处理Ⅲ的林地平均螳螂株率可达71.3%,定殖情况最好。更多还原

【Abstract】 In order to research the control effect of Heortia vitessoides with Hierodula patellifera in Aquilaria sinensis woodland, in the two testing points of Gongguan Town of Maonan District and Guanzhu Town of Dianbai District in Maoming City, the adult and egg sheath of the second generation of H.patellifera bred in artificial indoor room were put into the A.sinensis woodland.Their effects on the leaf loss rate, H.vitessoides population density and H.patellifera bearing A.sinensis rate with three different modes were investigated.The leaf loss rate of A.sinensis woodland in treatment Ⅲ(release 5 adults per plant+release 150 egg sheaths per hectare) was lower by 33% and 49.2% than CK(65%), respectively.H.vitessoides population density was 75 heads per plant, which was lower by 74.0% than CK(288 heads per plant).Therefore, H.vitessoides was not a disaster(disaster standard: leaf loss rate>60%), and the control effect was good.The average H.patellifera bearing A.sinensis rate of treatment Ⅲ was 71.3%, having the best colonization.更多还原
