  3. The hemolymph immune reaction of american cockroach to the entomopathogenic fungus, metarhizium anisopliae isolate cqma102, which is broadly used in locust control, was studied in the research. the results will enrich our knowledge about insect immune mechanism and the insecticidal mechanism of entomofungus. they will also be the fundamental work for insecticide development

    本研究以重要的室內蜚蠊種類? ?美洲大蠊（ periplanetaamericana ）為實驗材料，採用蜚蠊的非致病菌? ?金龜子綠僵菌（ metarhiziumanisopliae ） cqma102菌株作為供試菌，較系統地研究了綠僵菌孢子進入蜚蠊體腔后（點滴和注射處理） ，蜚蠊血淋巴某些理化性質的改變、血淋巴的免疫反應以及蜚蠊的行為反應等，有助為研究昆蟲的抗病機理和生物殺蟲劑的殺蟲機理，同時也為生物殺蟲劑的開發提供了必要的基礎。
  4. The two areas are important in locust control in china because of the frequent massive outbreaks of locusta migratoria manilensis ( meyen ). the selection pressure of op was found higher in huanghua - hebei and beidagang - tianjin than in pingshan - hebei and wudi - shandong. ld50 values for malathion of huanghua - hebei and beidagang - tianjin are higher than those of pingshan - hebei and wudi - shandong

    天津北大港、河北黃驊及河北平山三種群對馬拉硫磷的ld _ （ 50 ）值分別是山東無棣種群的1 . 96 、 1 . 8及1 . 02倍，這說明，我國重點蝗區殺蟲劑的選擇壓力已經造成當地東亞飛蝗種群對常用殺蟲劑的敏感性下降。
  5. Control of prairie locust with metarhizium metsch sorokin and its influence on biodiversity of locust

    綠僵菌防治低密度草原蝗蟲對蝗蟲多樣性的影響
  6. So far the chemical controls are still the major measures taken in locust abatement programs in china. in spite of the effectiveness and convenience, the frequent use of insecticides both in quantity and variety has caused a series of problems like locust resistance development, increased control difficulty and rising cost

    我國目前控制蝗蟲危害的手段主要是採用化學藥劑來降低蟲口密度，化學防治雖然具有快速、高效、使用靈活等優點，但是隨著農藥品種及數量的增加和無限制地使用農藥，會導致引起蝗蟲的抗藥性、農藥的效能降低、農藥生產成本增加等一系列問題。
