The use of Attractive Toxic Baits (ATBs) is considered to be a low-risk practical method for controlling cockroaches. This study evaluates the attractiveness of a lab-made, fipronil-containing bait, and its effect on the food consumption and mortality of the German cockroach Blattella germanica, under field and laboratory conditions. Different developmental stages of the cockroach were used to determine their preferred carbohydrate/protein rich foods and examine the effectiveness of lab-made baits. The analysis of variance (ANOVA) with Tukey's Test was determined using SAS 9.1 and GraphPad Prism software programs. The significance level was considered at p<0.05. The most-consumed foods were carbohydrate-rich foods (biscuit and banana powder) and food consumption rate was highest in non-gravid females. The most attractive bait ingredients were 20% roasted peanut butter, 50% biscuit and 30% banana powder. The highest lethality was recorded from the baits containing 0.02% fipronil under laboratory conditions, while infested houses baited with the lab-made bait showed 76.5% and 100% decline, respectively, in cockroach numbers in the first- and fourth-week post-baiting. In conclusion, palatable foods with a pleasant odour, like biscuit powder, banana powder and peanut butter were the most effective ingredients for the ATBs. The ATBs impregnated with 0.02% fipronil provide a promising approach for control of the German cockroach. However, there is a need to evaluate the potentials of the lab-made baits, under laboratory and field conditions, in the control of other health-important cockroaches.
使用诱捕毒饵（ATBs）被认为是一种控制蟑螂的低风险实用方法。本研究评估了一种实验室自制的含氟虫腈诱饵的吸引力，及其在野外和实验室条件下对德国小蠊食物消耗和死亡率的影响。使用蟑螂的不同发育阶段来确定它们对富含碳水化合物/蛋白质食物的偏好，并检验实验室自制诱饵的有效性。使用SAS 9.1和GraphPad Prism软件程序进行方差分析（ANOVA）和Tukey检验。显著性水平设定为p<0.05。消耗最多的食物是富含碳水化合物的食物（饼干和香蕉粉），非孕雌虫的食物消耗率最高。最具吸引力的诱饵成分是20%的烤花生酱、50%的饼干和30%的香蕉粉。在实验室条件下，含0.02%氟虫腈的诱饵致死率最高，而用实验室自制诱饵诱捕的房屋中，在投饵后的第一周和第四周，蟑螂数量分别下降了76.5%和100%。总之，气味宜人的可口食物，如饼干粉、香蕉粉和花生酱，是诱捕毒饵最有效的成分。浸渍0.02%氟虫腈的诱捕毒饵为控制德国小蠊提供了一种有前景的方法。然而，有必要在实验室和野外条件下评估实验室自制诱饵在控制其他对健康有重要影响的蟑螂方面的潜力。
