The application of plant material is the German cockroach in biological control of a potential growth bias. This study selected three big kinds of a total of 14 plant material of Blattella germanica control is studied, and of two often use repellent agent and two often use sanitary insects insecticides against Blattella germanica action to stop the determination, in order to plant material role comparative evaluation. Select the 7 plant source compounds, their toxicity against Blattella germanica and repellent, illustrates the determination results, Fuji, toosendanin and azadirachtin have different levels of blattellagermanica stomach toxic effect, the Fuji effect in ethyl acetate is strong, 8 hours of death rate has reached 100%, toosendanin lignin and azadirachtin on Blattella germanica also expressed a certain poison effect, not Yacha also invented the Azadirachtin and matrine on Blattella germanica development have teratogenic effect, matrine and toosendanin affect the egg sheath; further to these kinds of compounds repellent research results, notes of berberine hydrochloride Fuji, EC and azadirachtin have repellent effects on different levels of Blattella germanica, the repellent rate were 96. 7%, 51. 3% and 50. 1%, other observations to rotenone ethyl acetate solution and hydrochloric acid berberine against Blattella germanica with strong contact toxicity, the tested insect all knocked down the time separation for 8 hours and 48 hours. Determination of annotation of different concentration of toosendanin, concentration of toosendanin is high, Blattella germanica died more quickly, with 0. 5%, 1%, 2% toosendanin ethyl acetate solution of Blattella germanica LT50 were 18 and 15. 2, 14. 1 days, 0. 25% of Melia toosendan) ethyl acetate solution of Blattella germanica has no death effect by; when toosendanin hormone concentration increases to 2%, of Blattella germanica induced death consequences strengthen effect is not significant. Research shows four plant extracts of Blattella germanica: orange peel oil has good against the German cockroach kills the consequences. Contacting the result annotation, orange peel oil, mustard oil and ginger juice on b.germanica nymphs expressed must level contact toxicity effect, the revised death rate of isolation rate was 58. 62%, 29. 31% and 15. 52%, observation has not yet issued next night garlic extracts on German cockroach killing effect. Repellent test results annotations, cold soak extraction and Soxhlet extraction of orange peel oil, ginger juice, mustard oil, and garlic extract were of Blattella germanica show a certain level of repellent effect, the first day of flooding to avoid isolation rate was 77. 8%, 42. 5%, 48. 8%, 61. 1%, 96. 5%, the duration of 4, 7, 2 isolates, 8 and 14 days. The 1% butyl nasal spray oil, 1% oil of turpentine, camphor ethanol solution the planted were biological repellent test annotation, butyl nasal spray oil and turpentine oil on Blattella germanica first day driving to avoid isolation rate was 92. 8% and 81. 5%, and camphor on German cockroach repellent effect is not expressed. In to effect, butyl nasal spray oil and turpentine against the German cockroach repellent were increased with the passage of time has significant increments, turpentine, a week after the consequences have been very weak. 10%DMP and 10%DEET of German cockroach repellent experiments show that these two kinds of chemicals on the German cockroach repellent rate 1 hours after the separation of 56. 7% and 82. 4%. The effect of holding on, with the passage of time, the repellent effect of agile weakened, especially DEET, to second days have not shown repellent effect; DMP to fifth days after repelling probation gone. 目录: |
