摘要
通过触角电位(EAG)和嗅觉仪等技术,测定了自然和室内条件下,蕉藕和几个玉米品种对亚洲玉米螟的产卵诱集作用。结果表明:(1)自然条件下,蕉藕叶片上亚洲玉米螟的落卵量显著高于供试玉米品种。(2)室内条件下,亚洲玉米螟在涂有0.1g.ml-1和10g.ml-1浓度蕉藕叶片粗提物的玻璃板上的平均落卵量显著高于供试玉米品种。EAG反应结果显示,亚洲玉米螟对蕉藕和4个玉米品种叶片粗提物均可产生EAG反应,多数反应相对值之间无显著差异。但在0.1g.ml-1浓度时,交配雌蛾对蕉藕叶片粗提物的反应相对值显著高于供试玉米品种。行为测定结果表明,蕉藕叶片粗提物对亚洲玉米螟交配雌蛾、处女雌蛾和雄蛾均有较强的诱集作用,其平均诱捕率显著高于供试玉米品种。经相关性分析显示,田间试验与行为反应结果之间有极显著的相关性。综合表明,蕉藕对亚洲玉米螟有显著的产卵诱集作用,且这种作用在0.1g.ml-1至10g.ml-1的范围内有随叶片粗提物浓度降低而升高的趋势。
By using electroantennography（EAG）,olfactometer,and other technologies,the ovipositional attraction of Canna edulis Ker and several maizes to Ostrinia furnacalis（Guenée）at the natural and indoor conditions were studied.The results revealed that：（1）At field conditions,the numbers of eggs of O.furnacalis oviposited on C.edulis were significantly higher than that on maizes.（2）At the indoor conditions,the numbers of eggs on the glass board coated with C.edulis extracts were significantly more than maizes at the two concentration conditions（0.1 g·ml-1 and 10 g·ml-1）.The results of the EAG showed that O.furnacalis had responses to extracts of C.edulis and 4 maizes,moreover all these responses had no significant difference.Only at the concentration of 0.1 g·ml-1,the EAG relative potential of the mated females to C.edulis showed significantly higher,compared with the extracts of maizes.The behavior response bioassay indicated that C.edulis extractant had the strongest attractiveness to all groups of O.furnacalis adults,and the mean trappability of C.edulis extracts to O.furnacalis exceeded significantly that of maizes.Relativity analysis showed that the results of field experiment and behavior reaction had very significant regression relationship.Altogether,all data suggested that C.edulis had significantly ovipositional attraction to O.furnacalis,and these attractiveness decreased with the increase of the concentration of leave extractant between 0.1 g·ml-1 and 10 g·ml-1.
