Sugar is a phagostimulant component in the German cockroach bait. Knowledge of the chemosensory response of German cockroaches on a type of sugar is needed to design bait formulations. This study aims to determine latency behavior of sugar selection in German cockroaches, Blattella germanica L. Observation method used behavior sampling with  Closed Circuit Television (CCTV) cameras. Observations were made of fifteen mixed sex individuals from VCRU, BKL, PDG, JKT-b, and PKU-b strains with a choice of plain agar and agar containing glucose, fructose, sucrose, or maltose respectively. Observations were carried out starting at 6:00 a.m. to 6:00 p.m. in the test arena, which contained treatment, water and shelter. Data were analyzed with two-way ANOVA, followed by Duncan's test at p < 0.05. The correlation between sugar and latency behavior was analyzed with Redundancy Analysis (RDA) using Canoco program version 4.5. The results showed that latency behavior was influenced by treatment at p < 0.05 (F (1.4) = 3.32), but not affected by strains. The fastest latency in VCRU, BKL, and PDG strains went to maltose, sucrose, and control, whereas in JKT-b and PKU-b strains latency went to treatment in almost the same time range. The results of the Redundancy Analysis showed a correlation between treatment with latency behavior of 0.71 (axis 1) and 0.43 (axis 2) with a total variance reaching 79.8%. VCRU, BKL, and PDG  strains have similar latency behavior patterns in sugar selection compared to the JKT-b and PKU-b strains.
