【摘要】 研究了6种引诱剂、2种诱捕器以及不同风向对红火蚁的野外诱捕效果.结果表明:用于试验的引诱剂中有4种对红火蚁有一定的引诱作用.其中,引诱剂TB1(鱼粉50g、蛋白胨40g、10%蔗糖水10ml、大豆油20ml)的效果最好,平均每个诱捕器诱捕红火蚁77·6头;引诱剂TB2(火腿肠)的效果次之,平均每个诱捕器诱捕红火蚁58·7头;TB4(10%蔗糖水10ml、甘蔗粉100g、大豆油20ml)和TB6(玉米粉100g、大豆油20ml)分别能诱捕到红火蚁7·7和29头;TB3(10%蔗糖水10ml、玉米粉100g、大豆油20ml)和TB5(蜂蜜)未诱捕到红火蚁.离心管诱捕器的诱集效果显著好于纸碟诱捕器,两种诱捕器分别诱捕红火蚁75·2和35·0头.各种饵剂在下风区的诱集效果明显好于上风区.更多还原

【Abstract】 A field study was made to investigate the trapping effects of different attractants, traps, and wind directions on Solenopsis invicta. The results showed that among the test attractants, TB1 (50 g fishmeal, 40 g peptone, 10 ml 10% sucrose water solution and 20 ml soybean oil) had the best effect, followed by TB2 (ham), TB6 (100 g cornmeal and 20 ml soybean oil) and TB4 (10 ml 10% sucrose water solution, 100 g sugarcane powder and 20 ml soybean oil), with a mean capture efficiency being 77.6, 58.7, 29 and 7.7 individuals per trap, respectively. No S. invicta was trapped with TB3 (10 ml 10% sucrose water solution, 100 g cornmeal and 20 ml soybean oil) and TB5 (honey). Tube trap was superior to dish trap, with a trapping efficiency of 75.2 and 35 individuals per trap, respectively. The attractants had better effects in leeward than in windward.更多还原
