摘要: 以成虫取食孔为选择性指标,在室内就美洲斑潜蝇对22种不同蔬菜的选择性进行了试验,结果表明该虫对不同寄主的选择性大小依次为豆类>瓜类>茄科>十字花科等叶菜类;而非选择性试验中美洲斑潜蝇在10种供试蔬菜的9种上都可取食产卵并完成完整世代,但在不嗜食寄主上各虫态的一些生物学参数受到明显影响,因此美洲斑潜蝇对不同寄主既有选择性又有很强的适应性,因而有扩大其寄主范围的潜力

Abstract: Using the number of feeding puncture as the selectivity indicator,we found in laboratory that the selectivity order of American leafminer to the 22 kinds of vegetables is pea family>gourd family>nightshade family>mustard family and leaf vegetables;In the non-choice test,American leafminer could feed and oviposit on nine of ten kinds of vegetables and complete the whole generation. However the biological parameters were affected obviously in some unpreferential vegetables. This non-choice test sugge...
