【摘要】 测定了棉铃虫雌、雄蛾对7种花香化合物的触角电位(EAG)反应 结果表明,各种花香化合物均能引起棉铃虫较强的触角电位反应,雌、雄蛾对花香混合物(苯甲醛30%+苯乙醇30%+苯甲酸乙酯40%)的反应最强,相对反应值分别为220,176;对苯乙醇的反应次之;棉铃虫雌虫对不同剂量花香混合物的触角电位反应随剂量增加而增加 不同花香混合物在田间的诱蛾效果以配方G(苯甲醛100μL+苯甲醇100μL+苯乙醇200μL+乙酸苯甲酯600μL)最好,累计诱蛾量达到了196头.更多还原

【Abstract】 The EAG (Electroantennogram) response of female and male Helicoverpa armigera to a range of volatile components from flower was tested. The results show the components could provoke significant EAG responses of Hellicoverpa armigera.The strongest response was provoked by a mixture(30% of benzaldehyde,30% of benzyl ahcohol,and 40% of ethyl benzoate). The relative values were 220 and 176. The amount of H. armigera was positively correlative with the dose. The attracted effect of the compound was tested in the field.The effect of mixture G (benzaldehyde 100 μL, benzyl alcohol 100 μL,phenylethyl alcohol 200 μL,benzyl acetate 600 μL) was the best,trapping 196 moths.更多还原
