摘  要:
室内测定了马铃薯块茎蛾成虫对5种寄主植物(马铃薯、烟草、番茄、茄子和辣椒)的产卵选择性,并测定了该虫对5种寄主植物5种不同质量浓度(0.25~4.00gE/mL)的叶表漂洗物的产卵反应,结果表明:马铃薯块茎蛾显著趋向于马铃薯及烟草的叶片上产卵。对寄主叶表漂洗物产卵反应的试验结果表明:4.00gE/mL烟草叶表漂洗物对马铃薯块茎蛾的产卵有极显著促进作用;1.00gE/mL马铃薯叶表漂洗物、2.00gE/mL烟草叶表漂洗物、2.00gE/mL番茄叶表漂洗物、1.00、2.00gE/mL茄子叶表漂洗物、0.50gE/mL辣椒叶表漂洗物分别对马铃薯块茎蛾的产卵有显著的促进作用;但2.00、4.00gE/mL马铃薯叶表漂洗物、4.00gE/mL茄子叶表漂洗物、4.00gE/mL辣椒叶表漂洗物分别对其产卵表现为显著地抑制作用。

摘  要:
The oviposition choices of potato tuber moth(PTM)(Phthorimaea operculella Zeller)adult for five host plants and leaf surface rinses of host plants were tested in laboratory.The results demonstrated,PTM preferred to oviposit on potato and tobacco leaves significantly;Leaf surface rinses of tabacco extremely significantly promoted PTM oviposition at a concentration of 4.00 gE/mL.The leaf surface rinses of potato at 1.00 gE/mL, tobacco at 2.00 gE/mL,tomato at 2.00 gE/mL,eggplant at 1.00 and 2.00 gE/mL and pepper at 0.50 gE/mL significantly promoted PTM oviposition respectively,but the leaf surface rinse of potato at 2.00 and 4.00 gE/mL,eggplant at 4.00 gE/mL and pepper at 4.00 gE/mL significantly inhibited PTM oviposition respectively.
