摘 要:
根据2002-2004年连续3年田间系统调查，樟巢螟在苏州地区1年发生2代，以老熟幼虫在被害香樟树冠下浅土层内越冬：第1、2代幼虫发生为害高峰期分别为6月下旬-7月初和8月下旬。9月初。田间药剂防治试验表明，在幼虫初孵期分别用4．5％高效氯氰菊酯、2．5％敌杀死乳油2000倍液，2．5％灭幼脲1号、1％杀虫素（Bt制剂）1000-1500倍液等药剂防治，效果明显，校正防效达75．7％-87．4％。多年田间防治实践表明，采用园林技术、人工防治、生物防治、药剂防治等综合防治技术能控制樟巢螟的发生为害。[著者文摘]

WU Xue-fen et al （Suzhou Polytechnical College of Agriculture , Suzhou, Jiangsu 215008 ）
Abstract:
Orthaga achatina Butier harm is more and more severe on Cinnarnomum comphcra （L.） Pres with the enlargement of the camphor growth areas in Suzhou from 1999, By the 2004 investigation,the percentage of damaged plants was up to 71.1% ,pest population of per plant was up to 23. By the 2002-2004 investigation ,the Orthaga achatina Butier occurrence is 2 generation per year. The occurrence peak of the first generation is from the last ten-day of June to the early July; The occurrence peak of the second generation is from the last ten-day of August to the early September. The field experiment showed：in the incubate stage of the first generation grub application of 4.5 % beta-cypemethrin,2.5 % deltamethrin 2000-fold dilution, 2.5 % diflubenzurou, 1% BT 1 000-1 500-fold dilution etc , and are resulted in the control efficiency reached 75.7 %-87.4 % ,this result was remarkable. At the same time,By application garden technology,manual,biology prevention and cure,the Orthaga achatina Butier can be completely controlled.[著者文摘]
