对苏云金杆菌和苏云金杆菌与美国白蛾核型多角体复配实验结果表明:单独使用苏云金杆菌,叶片的保存率达到60%,未发现死虫;HcNPV和BT复配,第7天发现少量死虫,第13天出现死亡高峰,为倒挂型典型病毒死亡症状和综合感染症状;第20天虫龄已达5~6龄,发现少量活虫,白蜡叶片保存率为85%。说明两种药剂复配具有良好防效及持续的控制作用,有效降低第3代幼虫对白蜡木的危害,达到生物防治要求。
對囌雲金桿菌和囌雲金桿菌與美國白蛾覈型多角體複配實驗結果錶明:單獨使用囌雲金桿菌,葉片的保存率達到60%,未髮現死蟲;HcNPV和BT複配,第7天髮現少量死蟲,第13天齣現死亡高峰,為倒掛型典型病毒死亡癥狀和綜閤感染癥狀;第20天蟲齡已達5~6齡,髮現少量活蟲,白蠟葉片保存率為85%。說明兩種藥劑複配具有良好防效及持續的控製作用,有效降低第3代幼蟲對白蠟木的危害,達到生物防治要求。
대소운금간균화소운금간균여미국백아핵형다각체복배실험결과표명:단독사용소운금간균,협편적보존솔체도60%,미발현사충;HcNPV화BT복배,제7천발현소량사충,제13천출현사망고봉,위도괘형전형병독사망증상화종합감염증상;제20천충령이체5~6령,발현소량활충,백사협편보존솔위85%。설명량충약제복배구유량호방효급지속적공제작용,유효강저제3대유충대백사목적위해,체도생물방치요구。
The result of aerial spray against Hyphantria cunea (Drury) with BT and BT/HcNPV complex formulation showed that .. Single use BT, rate of leaf protection reached 60%, not found dead insect; BT and HeNPV complex match re- sults:7 day found a small amount of death worm, 13 days appear death peak, For fuchsia type typical virus death symptoms and comprehensive symptoms of infection. The 20th day insect age has reached 5-6 age, found a small amount of live worm, rate of leaf protection reached 85 %, This means that two agents compound with good control effect and continuous control effect, effectively reduce the third generation larvae to ash harm to biological control requirements.
