We examined the effects of 3 active ingredients in baits containing glucose on a behaviorally resistant (glucose-averse, T-164) strain of Blattella germanica L. Baits with glucose and hydramethylnon or chlorpyrifos killed few T-164 individuals; however, ÞpronilÐglucose baits killed 60% of the cockroaches by day 14. Although ingestion levels were low, ÞpronilÐglucose baits were consumed more tha...

To choose effective drugs to prevent and control avian colibacillosis in North China, we investigated the resistance of 164 E. coli isolates (from Beijing, Tianjin, Inner Mongolia, Shanxi, and Hebei regions of China) to commonly used clinical sulfonamide antibiotics using a drug su...
