采用粘虫板和玉米根虫诱捕器对玉米（Zea mays L.）在吐丝发生后，以确定诱捕器颜色、嗅觉引诱剂和有毒诱饵分配器类型对玉米根虫甲虫（根萤叶甲（Diabrotica barberi Smith & Lawrence）和玉米根萤叶甲（Diabrotica virgifera virgifera LeConte））成虫捕获的影响。捕获D.在粘虫板上的巴贝虫（每种性别）的颜色不同，但不与存在或不存在的引诱剂（4-甲氧基苯乙醇[MPE]）。黄色诱捕器捕获的D.巴贝里。捕获D。黄姑鱼（雌雄各半）在粘虫板上的引诱力随颜色和引诱剂（4-甲氧基肉桂醛[MCHO]）的不同而不同，颜色和引诱剂之间的交互作用也显著。土星黄和铝箔诱捕器，每一个诱饵与MCHO，捕捉最大数量的D。玉米根比较商业品牌的粘性陷阱的测试表明，Multigard陷阱捕获更多的男性D。Barberi比Pherocon AM诱捕器。无诱饵的Multigard诱捕器捕获了最多的雄性D。v. virgifera，而雌性D.用MCHO作诱饵的Multigard诱捕器捕获玉米根。捕获D.玉米根虫诱捕器（用毒素和取食刺激物诱饵的小瓶型诱捕器）中的barberi不随颜色或引诱剂（MPE）而变化。颜色和引诱剂均影响对黑腹小蜂的引诱效果。v. virgifera：将土星漆成黄色并以MCO为诱饵的陷阱捕获了最多的D。玉米根捕获女性D。barberi因毒饵分配器的类型而异：平均捕获量在托盘型分配器的陷阱中最大。讨论了诱捕成虫的意义。barberi和D.玉米根
Studies were conducted using sticky traps and corn rootworm traps in fields of maize (Zea mays L.) after silking had occurred to determine effect of trap color, olfactory attractants, and type of toxic bait dispenser on captures of adult corn rootworm beetles (Diabrotica barberi Smith & Lawrence and Diabrotica virgifera virgifera LeConte). Capture of D. barberi (each sex) on sticky traps varied with color but not with the presence or absence of attractant (4-methoxyphenethanol [MPE]). Yellow traps captured the greatest numbers of D. barberi. Capture of D. v. virgifera (each sex) on sticky traps varied both with color and attractant (4-methoxycinnamaldehyde [MCHO]); interaction between color and attractant was also significant. Saturn yellow and aluminum foil traps, each baited with MCHO, captured the greatest numbers of D. v. virgifera. Tests comparing commercial brands of sticky traps showed that Multigard traps captured more male D. barberi than did Pherocon AM traps. Unbaited Multigard traps captured the greatest number of male D. v. virgifera, whereas most female D. v. virgifera were captured on Multigard traps baited with MCHO. Capture of D. barberi in corn rootworm traps (vial-type traps baited with toxin and feeding stimulant) did not vary with color or attractant (MPE). Both color and attractant affected capture of D. v. virgifera: traps painted Saturn yellow and baited with MCHO captured the greatest numbers of D. v. virgifera. Capture of female D. barberi varied with the type of toxic-bait dispenser: mean capture was greatest in traps with tray-type dispensers. Implications are discussed for trapping of adult D. barberi and D. v. virgifera.
