Objective To investigate tick infestation of a war readiness warehouse and its influencing factors and evaluate the outcome of the control measures. Methods The visual method, chemical stimulating method and the technique of dragging a blanket over the vegetation on the grounds were used for the survey on the tick damage and observation of the effects of tick prevention and control. Results The average tick bearing index in dog reached 2520, with the tick density in the war readiness warehouse between 8/400 cm² to 200/400 cm². The range where ticks infringed was consistent with that in which dogs were fed. Residual spray in the indoor environment was administered using the mixture of 0.2% fendona and 0.3% propoxur. D-cyphenothrin, with conventional spray done with 0.1% cyhalothrin and 2% fenthion in an outdoor environment. The density of ticks decreased to less than 3/400 cm² after the first spray and to zero after the second one. Conclusion Two residual sprays combined with the control of dog ticks in the environment contribute to the effective control of tick damage to the warehouse.

【Abstract】 Objective To study the synthesis control effects of the poison bait and the gel bait to Blattella germanica in the passenger trains.  Methods One percent acephate and 1% Yekang gel bait were applied exclusively or both were jointly used in the passenger trains. The density of B.germanica was monitored before and after treatment respectively. Results There was significant difference between the combined application of poison bait and gel bait and single application of poison bait（χ2＝17.146，P＝0.000）. The combined application of poison bait and gel bait also significantly differed compared to that of the single gel bait（χ2＝15.499，P＝0.000）. Conclusion The combined application of cockroach poison bait and gel bait had a remarkable efficacy to the fast killing of B.germanica and the maintenance of low cockroach density in the passenger trains.
